International Workshop Series CIA on

Information Agents

After twelve years, the annual international workshop series on cooperative information agents will close with its 2008 edition in Prague.
The research area of intelligent information agents is established within both the scientific community and the business world. But it has been a long way
to that since the term “intelligent information agent” has been coined in the seminal work of Mike Papazoglou and his colleagues in 1992. In fact, the
CIA workshop series was founded in 1997 to complement the conference series on cooperative information systems (CoopIS) at that time with a
small but distinguished workshop forum for all people interested in research and development of intelligent information agents for the Internet, the Web
and – later on – the Semantic Web. Since the beginning of the 1990s, an increasing number and variety of agent-based information systems in different
application domains such as e-health, e-government, bioinformatics, e-commerce, and logistics has been deployed. In addition, most of the original topics
of the CIA series have been taken up by major scientific conferences in relevant disciplines like intelligent agents and multi-agent systems, service-oriented
computing, information systems, and P2P computing by default now. Recently, the CIA series has been top-ranked 55 from 620 considered conferences
in the domain Artificial Intelligence/Machine Learning (, July 21, 2008).
So, personally, I think the series did successfully accomplish its mission in support of inter-disciplinary research of intelligent information agents.
Whether there will be a need and demand to continue with it or to join forces for a similar enterprise in the future remains to be seen; it largely
depends on the further evolution of the field and its sufficient coverage by other major events.
Therefore, I would like to very gratefully thank all authors of submissions, the participants, the invited speakers, as well as each of the brave local
organisation teams, the program co-chairs, and the program committee members of all editions for their absolutely impressive and encouraging
collaboration in various ways in the past dozen of years. My particular thanks go to the sponsors of the series for their generous support,
and last but not least to the incredible team at Springer for publishing all proceedings as volumes of the Lecture Notes in Artificial Intelligence
(LNAI) series.
Thank you!! 
With best wishes, Matthias Klusch

The CIA workshop series has been top-ranked 55 from 620 considered conferences in the domain Artificial Intelligence/Machine Learning;
its EIC value (Estimated Impact of Conference; normalized to be in the range 0.00-1.00 - the closer the number to 1.00, the better the conference)
 is 0.55. Weights used to determine EIC: CP: 30% - citation of papers; RR: 30% - quality of referees' reports; RS: 25% - availability of resources
to students by the conference (funds for travel, fees, hotel); JA: 10% - conference papers accepted/appeared in reputable journals after the conference;
IN: 5% indexing. Source: (Topics II, status as of July 21, 2008)


The objective of the international workshop series on cooperative information agents (CIA) is to provide a small but lively and inter-disciplinary forum for researchers, software developers, and managers to get informed about, present, and discuss latest high-quality results in advancements of theory and practice of agent-based intelligent and cooperative information systems, and applications for current and future open information and service environments in the Internet, Web, and semantic Web. Each event of the series is designed to offer the registered participants the following items for a very reasonable registration fee
The series has been founded in 1997; since then the events of the series are held annually at different locations across the world (though, up to date mainly in Europe). The proceedings of the series are regularly published as volumes of the Lecture Notes in Artificial Intelligence (LNAI) series of the Springer Verlag.


One key challenge of developing advanced agent-based information systems is to balance the autonomy of networked data and knowledge sources with the potential payoff of leveraging them by the appropriate use of intelligent information agents on the Internet. An information agent is a computational software entity that has access to one or multiple, potentially heterogeneous, and geographically and logically distributed data and information sources, pro-actively acquires, mediates, and maintains relevant information on behalf of its human users or other agents, preferably just-in-time. In other words, it is supposed to manage and overcome the difficulties associated with information overload in the open and exponentially growing Internet and Web. Originally, the term "information agent" has been coined by Papzoglou in his seminal work on intelligent cooperative information systems (1992).
Depending on the application and tasks at hand intelligent information agents may collaborate in open, networked data and information environments to provide added value to a variety of applications in different domains. Thus, research and development of information agents is inherently inter-disciplinary: It requires expertise in information retrieval, artificial intelligence, database systems, human-computer interaction, and Internet and Web technology.

   Awards of the Series

Since 2001, the series issues a Best Paper Award, and a System Innovation Award, to acknowledge and further stimulate highly innovative research and development, respectively, in the domain of intelligent information agents.

Nominations for the best paper awards are to be done by the program committee in due course of the reviewing process; for the best paper award only submissions to the workshop are eligible for nomination. Nominations for the system innovation award can be placed either by the extended organisational board of the workshop (PC, chairs, sponsors) concerning some regular paper submitted to the workshop, or by the author(s)/developer(s) themselves via an explicit request for nomination sent to one of the co-chairs of the workshop. Each nominee is requested to demonstrate a running prototype of the nominated system at the workshop to all participants and the jury. Explicit request by author/developer (no need to submit a regular paper) is via submission of a brief description of the considered system of information agents (max. 4 pages, informal, including figures, references) in terms of its (1) core functionality, main techniques used, and (publicly available reference to) experimental results, and (2) a brief summary of the innovative features of your system in comparison to other existing systems. In addition, each submission including such a description may also be nominated by the extended organisational board.
