- Object Memory Modeling.
W3C Incubator Group Report, Worldwide Web Consortium, 2011.
Abstract
This report summarizes the findings of the Object Memory Modeling Incubator Group. An XML-based object memory format is introduced, which allows for modeling of events or other information about individual physical artifacts, and which is designed to support data storage of those logs on so-called "smart labels" attached to the physical artifact. The group makes several recommendations concerning the future evolution of the object memory format at the W3C; these address connections to provenance modeling, the embedding of object memories in web pages, and potential benefits of an object memory API.

Abstract
In this paper we describe a demonstration as it was presented to a wide audience at the Hannover Messe Industrie 2010. The demonstration shows a future production scenario spanning several linked stages ranging from individual ordering over assembly, filling, and shipping to individual support and comprises in total 5 demonstrators from 5 partners. Visitors could order and configure their own product and how to ship. Products which were produced in this scenario were equipped with a so-called digital product memory. Via this digital product memory data is collected along the product life cycle from individual ordering, assembling, filling to shipping. At home the user could browse the digital product memory and benefit from individual services which build up on the digital product memory.

Abstract
Digital Object Memories, DOM, comprise concepts and technologies to physically and conceptually associate digital information with physical objects in an application-independent manner. By storing information about an object's properties, state, and history of use in its digital memory, objects become self-representative, which allows for novel kinds of open-loop applications in the Internet of Things. In this paper we report on work on performed on architectures for Digital Object Memories, concepts for interacting with Digital Object Memories, and the application of Digital Object Memories in the context of the Internet of Things.

Abstract
Auto-ID as well as traditional identification technologies such as barcodes allow for linking physical products with digital data. Thus products become "smart items", which may contribute to the consumer's retail experience in future retail environments. In this article, we discuss how digital assistants can utilize so-called digital product memories for personalized support during tasks typically for the interaction between consumer and product. A demonstration system allowed participants of an IT fair to explore various approaches to personalized support on the basis of this technology in a storyline spanning several spaces, some of them public, some private. Feedback gathered from 132 visitors indicates that this kind of support is in general perceived well; however, it also emphasizes the diversity of people's interest in interaction metaphors and means of privacy protection.

Abstract
Smart packaging solutions may support a patient in the intake of drugs - for instance, through the packages form factor or a linking of the packages physical artefact with digital data and services built upon this data. This article discusses the application potential of a so-called "digital product memory" in this domain. Starting point is a visionary scenario, in which the interplay of intelligent environments and medicine packages equipped with digital product memories allows for unobtrusively supporting a patient in dealing with situations that might affect his or her therapy compliance. In the following, components of a technical infrastructure are described, which are of particular relevance for the envisioned kind of support. This discussion is complemented with a review of prototype implementations of interaction mechanisms taken from the scenario.

- Remarkable Objects: Supporting Collaboration in a Creative Environment.
In Proceedings of the 12th ACM International Conference on Ubiquitous Computing (UBICOMP 2010), pp. 37-40, ISBN 978-1-60558-843-8, 2010.
Abstract
In this paper, we report the results of a field trial of a Ubicomp system called CAM that is aimed at supporting and enhancing collaboration in a design studio environment. CAM uses a mobile-tagging application which allows designers to collaboratively store relevant information onto their physical design objects in the form of messages, annotations and external web links. The purpose of our field trial was to explore the role of augmented objects in supporting and enhancing creative work. Our results show that CAM was used not only to support participants' mutual awareness and coordination but also to facilitate designers in appropriating their augmented design objects to be explorative, extendable and playful, supporting creative aspects of design work. In general, our results show how CAM transformed static design objects into "remarkable" objects that made the creative and playful side of cooperative design visible.

Abstract
Everyday objects tagged with sensors and actuators that communicate and cooperate provide the foundation of the Internet of Things. Most applications in the Internet of Things deal with information related to such objects in the one or other way, whilst Digital Object Memories comprise hardware and software components, which together provide an open and universal platform that allows for the continuous capture and conceptual and/or physical association of digital information with physical objects. As such, they support information exchange and reuse across environments and applications, and pave the way for novel kinds of applications and services.
The goal of this workshop is to unite these two perspectives on connected objects and object memory in a hybrid workshop format that combines traditional presentations and discussion with a practical experiment. As such, the workshop should bring together technical experts, artists, designers, and possible end-users of Digital Object Memories in order to discuss technical, social, privacy, and legal implications of object memory systems, to establish a common view on requirements to digital memories, and to leverage cooperation in future activities.

- Using Object Memories For Resource Efficiency.
In Proceedings of the International Workshop on Digital Object Memories in the Internet of Things (DOME-IoT) at UbiComp 2010, Technical Report DFKI-D-10-01, pp. 9-10, ISSN 0946-008X, 2010.
Abstract
Object memories support the creation of item-level records, which can be exploited for a deep analysis of processes a physical artefact is involved in. We believe that this technology has particular uses for conserving resources such as energy and water, and thus may provide a valuable contribution to an "Internet for Resource Efficiency". In this article, we discuss this idea on the basis of several application scenarios. We use these to identify research issues related to the application of object memories in this particular field in order to increase awareness of potential benefits and challenges and thus to stimulate research in this area.

Abstract
Physical design objects such as sketches, drawings, collages, storyboards and models play an important role in supporting communication and coordination in design studios. CAM (Cooperative Artefact Memory) is a mobile-tagging based messaging system that allows designers to collaboratively store relevant information onto their design objects in the form of messages, annotations and external web links. We studied the use of CAM in a Product Design studio over three weeks, involving three different design teams. In this paper, we briefly describe CAM and show how it serves as "object memory".

- Demonstrating the Application of Digital Product Memories in a Carbon Footprint Scenario.
In Proceedings of the 6th International Conference on Intelligent Environments (IE'10), pp. 164-169, ISBN 978-0-7695-4149-5, IEEE Computer Society, 2010.
Abstract
The carbon footprint is an environment indicator, which is of special interest not only for assessing and optimizing production and logistic processes, but also for addressing a growing interest of customers in the ecologic characteristics of a product. Its computation and processing are tightly bound to research challenges, such as the capturing and exploration of item-level data, and the aggregation of item-level process instances. In this article, we report about a demonstration system, which aims at illustrating visitors of a technology fair how these challenges can be addressed by means of item-level records created from input obtained via smart labels. In a scenario spanning several steps of a product's lifecycle, the system enables the creation and exploitation of these records. During each stage, the system combines item-level data with more general information related, e.g., to the product class and the underlying process model - with the ultimate goal not only to support the assessment of an item's carbon footprint, but also its reduction for future products of the same class.

Abstract
Smart labels enable novel item-centric ways of communication along a product's lifecycle. With respect to the open nature of a scenario ranging from manufacturer to consumer, the expectations to such "smart items" are diverse. In this article, we discuss the perspective of potential users and system architects on selected aspects of so-called digital product memories. Our report aligns information we acquired from 332 visitors of a complex prototype system presented at a public IT fair, an internal questionnaire where 14 members of the project SemProM reported about their vision of this concept from an application and technology point of view, and the ongoing implementation works within that project. Our observations address to a large extent research issues related to smart items in general and thus do not only provide an insight to the research development process in this particular project, but also can be exploited for design decisions in other projects in this field.

Abstract
Bedingt durch den rapiden Fortschritt der Computertechnik wird die Zukunft der Kennzeichnung von Produkten neue Möglichkeiten mit sich bringen. Extreme Miniaturisierung wird erlauben, Produkte mit nahezu unsichtbaren Informationsträgern auszustatten. Sensorknoten können lokal Verarbeitungsschritte durchführen, Netzwerke bilden und umfangreiche Daten am Objekt archivieren. Ein mittels solcher Technik gekennzeichnetes Produkt kann sich selbst beobachten, mit seiner Umgebung kommunizieren, und seine Beobachtungen und Interpretationen in einem eigenen Speicher ablegen - und besitzt damit die Möglichkeit, ein Digitales Produktgedächtnis aufzubauen.

Abstract
Adherence to therapy, what is termed "compliance", is a very important topic in Medicare. It has considerable effects not only in terms of enhancing quality of life for patients, but also in reducing the financial burden on the health care system. The individualized weekly medicament blister for patients (7x4 Box) from 7x4 Pharma increases the compliance and helps to keep the health expenditures as low as possible. A potential extension of the 7x4 Box could be a digital product memory which makes the imprinted data on the box electronically accessible in order to enable new innovative services which helps to increase the compliance. If we do not secure the data from an unauthorized access there is a possibility that third parties can read out the data unperceived and on a grand scale. In this paper we show how we can realize an authorized access - individually or role-based - on the data via identification by the new German electronic identity card.

Abstract
In the Project "Semantic Product Memory" we exploit the lessons learned so far for the general design of a Digital Product Memory (DPM). DPMs can be used along their product's life cycle to collect data by different instances. In case of the individualized weekly medicament blister for patients from 7x4 Pharma not only the collected data but even the product itself is private. If we equip such a product with a DPM the collected data should be accessible -individually or role-based- only by authorized persons. This authorized access can be accomplished via a roles and rights management system and a secure identification provided by the new German electronic identity card. With our demonstrator we will present a system, which allows an authorized access on a DPM. Depending on the rights and roles of a user different data and different views will be available and displayed accordingly.

Abstract
There are many strategies to assist the user in pervasive environments. In some cases, the user has to achieve a goal according to a plan known by the environment. We address the issue of enabling the environment to be aware of which task of the plan is currently on-going. We present a strategy that makes use of temporal patterns called memory chronicles and that watches events that occur in object memories to recognize if they match any memory chronicle of any task of the plan. We take the example of a smart kitchen where tools and ingredients are considered as objects with memories and where the cook reproduces a recipe according to a recipe plan known by the kitchen. We explain how the kitchen makes use of memory chronicles to applying cooking task recognition and guide the cook through the recipe plan.

Abstract
The continuous collection of digital information via smart labels attached to physical objects is a promising way to support information availability across all stages of a product's lifecycle. Since such "digital product memories" may contain a vast amount of heterogeneous data, we expect a strong demand for user support in tasks related to information retrieval and discovery. In this article, we focus on the interaction between consumers and digital product memories in a retail scenario. On the basis of several prototype implementations, we summarize various ways of retrieving and presenting product-related information with the goal to shed some light upon aspects of relevance for the interaction between users and object memories in general.

Abstract
Smart objects are a promising way to achieve digital support for our daily life. However, despite the constantly decreasing manufacturing costs of electronic components, complex embedded systems are still too expensive in relation to the price of most everyday objects. In this paper we demonstrate, how complex applications can still be realized with cheap and weakly instrumented smart objects by establishing so-called object memories and consequently exploiting the capabilities present in the static environment to use and update this memory. We illustrate this idea with a concrete application scenario, in which we accompany a frozen pizza through selected stages of its lifecycle. We report on requirements regarding technology and memory content, and describe our memory framework implementation as well as two hardware demonstrators from the smart home domain.

Abstract
The ongoing augmentation of our everyday environment with digital artifacts and electronic sensors enables machines to observe with increasing precision a user’s interaction with the environment and contained applications. If these observations are recorded over time, then the resulting collection can become a user’s personal “digital memory”. Like a blog, such a semi-automatically built resource can be of interest for sharing information between users. With this article, we want to provide some answers to the question of how people exploit other persons’ digital memories, and how the resulting sharing behavior can be evaluated. We report about two small-scale user studies, which emphasized different aspects of the exploitation of shared personal memories in the everyday. Our report comprises a short description of a platform for collecting and sharing digital memories used in both scenarios, the study methods, and a discussion of the results. These confirm the utility of the respective sharing approaches and provide an insight to people’s expectations concerning the interaction with such a resource.

Abstract
The popularity of the ubiquitous sharing of user-created content motivates the authors to research a general content-sharing framework. They focus on sharing digital memories automatically created by intelligent environments. On the basis of three different application scenarios and several user studies, they provide insight into the framework's basic concepts, including a memory model. They also discuss various kinds of shared content and methods for managing access to such content in the memory model.

Abstract
Enhancing user perception in smart environments is an active area of research. Its foundation is the use of sensor technology in order to capture automatically events that might otherwise escape the user's knowledge. Organized in a personal diary, such events may be exploited for various kinds of user support. However, while the approach requires that the user is not forced to interact with incoming information, the information captured should nevertheless match her expectations. In this article, we describe various strategies that let the user control the creation and structuring of events generated in a virtual shopping environment. Our report comprises a summary of information sources offered to the user in this setting as well as methods employed to construct a diary of shopping actions in a semi-automated way.

Abstract
An automatically created digital memory enables an intelligent environment to accompany its user's actions with information from past events. Reminders, recommendations of action alternatives, and the sharing of personal digital memories among users are examples of applications, which may not only serve the user's comfort, but also support older people at home, thus keeping them independent and integrating them in their social network. In this article we use the prototype of a digital kitchen assistant in order to illustrate how this approach may be deployed in an everyday environment. Our report comprises the technical setup as well as first results from a pilot study about "Cooking based on digital memories".

Abstract
Intelligent assistants need precise knowledge about activity sequences and the habits of their users so as to support them in an adequate manner. The following contribution addresses an approach to user support, which takes advantage of the object centred nature of many day-to-day activities. By means of application examples from the everyday, we illustrate how a combination of smart items and digital memories allows for realizing innovative support mechanisms, which take into account static knowledge about objects as well as situational observations and historical data. Here, we devote special attention to applications originating from the sharing of data gathered this way between users and systems.

Wir illustrieren anhand von Anwendungsbeispielen, wie durch die Kombination von Smart Items und digitalen Gedächtnissen innovative Formen der Benutzerunterstützung möglich werden, die statisches Wissen über Objekte mit dynamischen Informationen und historischen Daten kombinieren. Besondere Aufmerksamkeit widmen wir hierbei Anwendungsmöglichkeiten, die aus dem Austausch der so gewonnenen Daten zwischen Benutzern und Systemen entstehen.

Abstract
Selecting relevant people is crucial for collaborative systems exploiting other users' experiences. With the new developments of the Web and ubiquitous technologies, various user data may support people selection. Given the wide range of user data sources, the question is now how to select appropriate users meeting the information seeker's goal. We propose recommendations for the design of people search interfaces, providing an overview of the user data and tools of relevance and two examples of how such recommendations can be met in one single interface, ensuring the selection of appropriate and reachable people. We also show applications of people search interfaces in different scenarios.

Abstract
The rapid deployment of low-cost ubiquitous sensing devices - including RFID tags and readers, global positioning systems, wireless audio, video, and bio sensors - makes it possible to create instrumented environments and to capture the physical and communicative interaction of an individual with these environments in a digital register. One of the grand challenges of current AI research is to process this multimodal and massive data stream, to recognize, classify, and represent its digital content in a context-sensitive way, and finally to integrate behavior understanding with reasoning and learning about the individual's day by day experiences. This augmented personal memory is always accessible to its owner through an Internet-enabled smartphone using high-speed wireless communication technologies. In this contribution, we discuss how such an augmented personal memory can be built and applied for providing the user with context-related reminders and recommendations in a shopping scenario. With the ultimate goal of supporting communication between individuals and learning from the experiences of others, we apply this novel methods as the basis for a specific way of exploiting memories - the sharing of augmented personal memories.

Abstract
The exchange of personal experiences is a way of supporting decision making and interpersonal communication. In this article, we discuss how augmented personal memories could be exploited in order to support such a sharing. We start with a brief summary of a system implementing an augmented memory for a single user. Then, we exploit results from interviews to define an example scenario involving sharable memories. This scenario serves as background for a discussion of various questions related to sharing memories and potential approaches to their solution. We especially focus on the selection of relevant experiences and sharing partners, sharing methods, and the configuration of those sharing methods by means of reflection.

Abstract
Dense logging of a user's interactions with an intelligent environment enables the creation of artificial memory structures, which augment the user's natural memory. In this article we discuss the interrelationship between such augmented memories and ubiquitous user modeling, and the particular benefits of linking both concepts. On the basis of a prototype implementation, we illustrate how ubiquitous user modeling contributes to the building of personal, augmented memories, and discuss how the latter one may enrich ubiquitous user models and thus grant other applications access to memory content. We conclude with a discussion of how users may exploit such hybrid systems to share their personal memories with other users.

In this article, previous work concerning the building, exploitation, and sharing of a so-called personal digital memory, which was conducted in the projects SPECTER and SharedLife, is summarized with a special focus on its potential for life long user modeling.

Abstract
Current technology makes it increasingly feasible for personal assistance systems to create an augmented episodic memory that supplements their users' own episodic memory. After considering the question of what such an augmented episodic memory might be useful for, we present a proof-of-concept system SPECTER that realizes this idea. We consider in turn the challenges of (a) automatically capturing and appropriately representing information about the user's actions and experiences; (b) enabling the user to review and revise the information captured; (c) offering functions based on the episodic memory that can help the user deal more effectively with everyday situations; and (d) determining in what situations to make these functions available proactively.

Abstract
Limitation of the human memory is a well-known issue that anybody has experienced. Some of these can be addressed by exploiting one of the strengths of computers: the ability to store huge amounts of information for an unlimited time without loss of precision. And actually, state-of-the-art mobile devices in general provide features for creating reminders, linking notes to time and dates, and for managing time. However, these techniques require the user to capture this data manually, and thus the quality of such memories greatly depends on her cognition and carefulness. Thus, this chapter provides a discussion of various challenges related to building and exploiting such augmented personal memories in everyday's life. It concentrates on a number of crucial aspects: the importance of abstraction processes for building this memory and the design of a user interface for supporting interaction between user and memory. It further illustrates authors' approach with examples of processing and exploiting information about the user's location in the shopping assistant SPECTER.

In Proceedings of the 2nd International Conference on Intelligent Environments (IE 2006). Athens, Greece, July 5-6, 2006.
Abstract
One of the human strengths is to utilize past experiences to solve problems. This process can be technically supported by collecting and exploiting the history of a user's interactions with an intelligent environment. However, most of today's applications cannot or do not take on the additional burden of providing the user with sophisticated memory functionality. In this paper we present the concept of an open personal memory, which allows arbitrary applications to contribute knowledge to the memory with minimal extra effort. We describe a proof-of-concept implementation and show how users can exploit such memories.

Abstract
Advances in technological support for augmented personal memories make possible new ways of enhancing the process of product recommendation. Instead of simply analyzing information about a user's past behavior in order to generate recommendations, a recominder1 system can additionally supply various types of information from the user's augmented memory that allows the user to take a more active role in the search for suitable products. We illustrate the paradigm of recomindation with reference to a prototype implementation of the system SPECTER in a CD shopping scenario and the results of a study with 20 subjects, who found most of the recomindation functionality to constitute a useful enhancement of their shopping experience.

Abstract
A comprehensive log of the user's behavior together with corresponding context descriptions allows adaptive systems to learn about users, to identify their habits, and to improve the quality of user support. In addition, users can apply such knowledge to learn from others and about themselves. We describe in this article how these issues can be addressed by the means of augmented memories created from sensor data automatically captured in an intelligent environment. After discussing how to represent and process such memories, we show how they can be exploited by adaptive systems as well as by their users. One promising way of exploiting memories is to share them with others; this is reflected by the last part of our contribution where we explain how ubiquitous user modeling may enable the sharing of information inferred from memories.

Abstract
User support which takes into account the user's current context is a key issue of ambient intelligence applications. In this contribution we address the question of how a user may configure and keep control of situated user support. Background of our work is a system, which creates an augmented, personal memory from events perceived in an instrumented environment. We show how the user may - assisted by the system - perform a collaborative introspection of this memory in order to learn about and to exploit past events for user support. In particular we discuss methods for evaluating events and for acquiring proactively feedback in order to improve the quality of a binding between situations and system services.

Abstract
Keeping a history of the user's interaction with the environment is of use for many reasons. However, collecting, structuring, accessing, and reviewing such potentially large amounts of information is not trivial. In this paper we present our ideas for a memory model for pervasive computing applications addressing these questions. The proposed architecture allows applications to deliver ad-hoc support taking into account the user's history and general attitudes as well as providing a personal diary to review events and retrieve memories. We also include a brief discussion of a novel user interface, which allows the user to bind services to general contexts based on his previous experiences.

Abstract
We discuss and illustrate design principles that have emerged in our ongoing work on a context-aware, useradaptive mobile personal assistant in which an extended episodic memory - the personal journal - plays a central role. The prototype system SPECTER keeps track of its user's actions and affective states, and it collaborates with the user to create a personal journal and to learn a persistent user model. These sources of information in turn allow SPECTER to help the user with the planning and execution of actions, in particular in instrumented environments. Three principles appear to offer useful guidance in the design of this and similar systems: 1. an emphasis on usercontrolled collaboration as opposed to autonomous system initiatives; 2. provision of diverse, multiple benefits to the user as a reward for the effort that the user must inevitably invest in collaboration with the system; and 3. support for diverse forms of collaboration that are well suited to different settings and situations. We illustrate the way in which these principles are guiding the design of SPECTER by discussing two aspects of the system that are currently being implemented and tested: (a) The provision of multiple, qualitatively differentways of interacting with the personal journal allows the user to contribute to its construction in various ways, depending on the user's current situation - and also to derive multiple benefits from the stored information. (b) SPECTER's collaborative methods for learning a user model give the user different ways in which to contribute essential knowledge to the learning process and to control the content of the learned model.

Abstract
Designing user assistance systems in intelligent environments poses many challenges. The system has to provide useful support for its user in everyday situations, while keeping the user interface as simple as possible. This requires a well-founded understanding of the user's needs, and deep knowledge of pervasive human-computer technology, such as RFID sensors and computer vision. In this paper, we present a new design method, based on Activity Theory, and a toolkit that supports the designer of ambient intelligence systems. The toolkit integrates a geometric location model with a symbolic activity model, so that the typical activities of the user can be analyzed with respect to the environment in order to identify useful assistance features. Furthermore, the system supports the designer to make the necessary decisions for the instrumentation of the environment, i.e. which sensors to use and where to place them.

Abstract
We revisit the top-level ontology Gumo for the uniform management of user and context models in a semantic web environment. We discuss design decisions, while putting the focus on ontological issues. The structural integration into user model servers, especially into the U2M-UserModel & ContextService, is also presented. We show ubiquitous applications using the user model ontology Gumo together with the user model markup language UserML. Finally, we ask how data from Web 2.0 and especially from a social tagging application like del.icio.us as a basis for user adaptation and context-awareness could influence the ontology.

Abstract
We propose an approach for using data from a social tagging application like del.icio.us as a basis for user adaptation. We discuss several algorithms for mining taxonomies of tags from tag spaces. The mined taxonomy can be used to define adaptation rules that determine how to adapt a system to a user given the user's personal tag space.
The contributions of this work are a description of an application scenario for taxonomymining algorithms, a discussion of algorithms by Mika[3], Heymann et al.[2], and Schmitz et al.[4], and the proposal of an extension to the algorithms that takes the contexts of tags into account when building a taxonomy. We look at the performances of the algorithms on a dataset retrieved from del.icio.us and give a tentative recommendation of what algorithm to use.

- Providing Context-Aware Personalization through Cross-Context Reasoning of User Modeling Data.
In Proceedings of the UM 2007 workshop on Ubiquitous and Decentralized User Modeling, pp. 2-7, Corfu, Greece, 2007.
Abstract
Existing personalization systems base their services on user models that typically disregard the issue of context-awareness. This work focuses on developing mechanisms for cross-context reasoning, i.e., inferences linking user model data in two different contexts. That reasoning process can augment the typically sparse user models, by inferring the missing information from other contextual conditions, and can better support context-aware personalization. Thus, the proposed approach improves existing personalization systems and facilitates provision of more accurate context-aware personalized services.

Abstract
The existing personalization systems typically base their services on general user models that ignore the issue of context-awareness. This position paper focuses on developing mechanisms for cross-context reasoning of the user models, which can be applied for the context-aware personalization. The reasoning augments the sparse user models by inferring the missing information from other contextual conditions. Thus, it upgrades the existing personalization systems and facilitates provision of accurate context-aware services.

Abstract
Starting from the assumption that an integration of digital services might help brick-and-mortar bookstores to compete with online sellers, we propose a recommender system which takes into account not only content-based similarity of books, but also local availability and spatial distance. This article addresses work in progress; its focus is on a particular question tightly connected to the user interface design of such a system: how to communicate results from these different information sources to a customer in a transparent way. We contribute to this topic with several design proposals and a discussion of feedback collected in a user study.

Abstract
Long-term records of user actions captured and recorded in an intelligent environment allow for realizing new kinds of user support, which exploit a user's past experiences for supporting his or her future actions. In this article, a mobile shopping assistant equipped with such augmented memories serves as background for a discussion of a user interface especially tailored to support typical functions of augmented memories including context-based reminding, generation of recommendations, and reflection on past experiences. Starting from interactions observed in a user study of the system, we report about how exchangeable and interconnected views on augmented memories can be applied in order to achieve a user interface, which presents the memory in a way appropriate for the user's current context. These views establish a display context, which together with the user's context, imposes constraints on the actual display of memory contents. In order to address this issue, we continue with an approach, which exploits the memory content ontology for deciding about a visualization style appropriate within a given display context.

Abstract
The personalized delivery of content is a way of making online content portals more attractive to end users, and consequently, nowadays many online portals provide varying ways of personalizing their service. In order to facilitate the creation of such personalized services, the IMAGEN toolset came into existence. IMAGEN aims at creating personalized content packages, where documents are selected from a repository with respect to the customer's interests, and are bundled to a package. The appearance of packaged documents may be revised in order to take the layout preferences of authors, service providers, and customers into account. In this contribution, we describe varying ways of personalizing the layout style of content packages, ranging from a plain exchange of styles as suggested by the content authors to a constraint-based style unification. In the sequel we describe how service providers as well as customers may take influence on that revision process in order to obtain personalized layout styles.

Zusammenfassung
Im Rahmen des IMAGEN Projektes werden Werkzeuge zur Erstellung personalisierter Web Portale entwickelt. Grundgedanke von IMAGEN ist es, auf Anfrage Informationspakete für den Leser aus vorhandenen Dokumenten zusammenzustellen, die bezüglich Inhalt und Layout den Präferenzen des Lesers weitmöglichst entgegenkommen. Dieser Beitrag bietet einen kurzen Überblick über die Architektur des IMAGEN Toolsets, gefolgt von einer näheren Betrachtung der Layout Komponente. Letztere verwendet Constraint-Techniken, um einen Stil zu ermitteln, der die Vorgaben der an einem Paket beteiligten Autoren mit den Präferenzen des Portal-Betreibers und des Lesers verschmilzt. Von besonderem Interesse sind dabei die Constraints, die zur Auswahl der Lösung verwendet werden. Wir stellen ein interaktives, grafisches Werkzeug vor, das die Justierung dieser Constraints anhand einer abstrakten Visualisierung der Menge der gültigen Lösungen erlaubt. Optional kann hier ein Clustering der Lösungsmenge durchgeführt werden mit dem Ziel, Gruppen ähnlicher Lösungen leichter zu identifizieren und somit die Analyse der Lösungsmenge zu vereinfachen.

Abstract
The background of this article is formed by work on IMAGEN, a toolset for the creation of Web portals that aim at providing their users with personalized content packages. After an overview of the system, we focus on the resolution of layout problems imposed by the content packaging approach. The core of the presented component for layout management applies constraint techniques for integrating layout preferences of authors, portal providers, and end users who receive the compiled content packages. Since IMAGEN aims at cross-platform delivery, we continue the discussion of our component with the question of how IMAGEN can be extended so that mobile access to personalized content packages becomes possible. Our discussion includes a description of experimental work conducted within the IMAGEN project. The focus of this work is on the customization of graphical representations for display on mobile devices with tiny screens. We have developed a module that uses techniques from the area of machine learning to chose from a set of available image transformations a transformation which most likely produces a reasonable result for a yet unseen image.

- Managing Layout Constraints in a Platform for Customized Multimedia Content Packaging. In Proceedings of the Working Conference on Advanced Visual Interfaces (AVI) 2002, pp 89-93, Trento, Italy, May 22-24, 2002.
Abstract
A promising approach to customize the delivery of multimedia content is based on methods for compiling content packages from repositories of existing media assets, such as text paragraphs and images. Since the authors of media assets may have specified layout preferences for their assets neither knowing in which package these assets eventually will occur, nor knowing the personal layout preferences of all potential customers, layout conflicts, such as incompatible style attributes, are preprogrammed when packages are compiled on the fly by an automated system. In this contribution we present a constraint-based approach for resolving layout conflicts in automatically compiled content packages. Depending on the number and nature of the layout constraints to be considered, many eligible layout styles may exist. In fact, the exploration of a style solution space creates a problem on its own. Therefore, we are also investigating clustering and visualization techniques to assist a system administrator in the exploration of the solution space. The work has been conducted in the context of the EU funded project IMAGEN which aims at the development of an integrated set of tools for the customized publication and distribution of multimedia content.

Abstract
We report on our work towards a layout management system that supports cross-platform delivery of multimedia content. As input, the system expects content packages that have been compiled automatically or manually from repositories of existing media assets, such as text paragraphs and images. Since the authors of these assets may have specified layout preferences neither knowing in which package their assets will occur, nor knowing the customer's layout preferences, layout conflicts, such as incompatible style attributes, are preprogrammed during packaging. We present a constraint-based approach for resolving layout conflicts in automatically compiled content packages. A further aspect of our work is cross-platform delivery. With a focus on the customization of graphical representations for display on mobile devices with tiny screens, we have developed a module that uses techniques from the area of machine learning in order to chose from a set of available transformations the one which may produce the best result for a yet unseen image.

Abstract
IMAP provides software tools that support the authoring of electronic presentation by helping the author in multimedia content selection and layout design. IMAP consists of a Content Manager and a Layout Manager. In this paper we present the usage of IMAP tools for the authoring of online newspapers. The content selection is based both on the author's specifications and the user's interests, where the interrelations between objects play an important role in the evaluation of the set of objects. Layout management relies on a set of layout requirements taken from a layout profile and an author-defined style sheet. As was demonstrated in our experiments, integrating of both techniques yields interesting newspapers, whose layout can be customized by the reader.

Abstract
Accumulating experience suggests that constraint programming is broadly applicable to many computationally intensive tasks, such as automated layout, where the problem is to articulate and apply constraints on the placement of objects in some limited space. Despite the appeal and popularity of this approach, the creation of a feasible system remains relatively challenging, as there are typically an incredible number of important details that arise when attempting to transform the abstract idea of constraints into a practical problem solving architecture. Here we explain our experience with such a development, which addresses the integration of constraint programming and artificial intelligence methods in the problem of layout for multimedia directories (MMD). Our goal is to provide a sketch of the overall process from idea to implementation, which relates each design decision to its theoretical foundation adapted for the practical situation at hand. The implemented system YPPS for yellow page directories provides a practical basis for explaining such decisions and for providing examples of the overall system operation.
