Abstract: Personal Publication Reader (PPR)
The Personal Publication Reader demonstrates how to provide personalized,
syndicated views on distributed Web data using Semantic Web technologies. The
application comprises three steps: The information gathering step, in which
information from distributed, heterogeneous sources is extracted and enriched
with machine-readable semantics; the reasoning step in which rules reason
on the created semantic descriptions and additional knowledge-bases like
ontologies and user profile information, and the user interface creation step
in which the semantic descriptions resulting the reasoning step are
interpreted and translated into a personalized user interface. As a showcase,
we demonstrate how to extract, syndicate and reason on information about
scientific publications from partners of the REWERSE project.

Abstract:
Location-awareness is one of the big keywords nowadays.
Different localization techniques are available, which differ in various aspects:
The Global Positioning System (GPS) for example is best known for outdoor positioning,
but unfortunately it does not work in buildings. The techniques for indoor positioning
often use WiFi hotspots, infrared beacons or ultrasound- or RFID-tags. These aproaches
differ in cost, reliability and precision, so it seems only natural to combine these
technologies to some sort of hybrid positioning system.
Our system uses infrared beacons and active RFID tags that are placed in the environment
and respective sensors on an PDA to determine the position of a user. The system can work
with either infrared beacons or RFID tags alone or, if both signals are available at the
current location, it combines the sensor readings with the help of geo referenced
Dynamic Bayesian Networks (geoDBNs) to get an even better estimation of the user position.
These geoDBNs help to cancel out false readings and to prevent the calculated position
from "jumping". Another aspect of our system is that the sensor readings and all the
required calculations are carried out on the personal device of the user
(there is no externel server involved) so that the positioning information is literaly
in the hands of the user (he is not being tracked). This helps to increase the user's
privacy concerns.

Abstract: We introduce the concept of Product Associated Displays - PADs - as a way of providing visual feedback to users interacting with physical objects in an instrumented environment. PADs are projected public displays created at locations that can be intuitively associated with the objects they show information about. The concept is illustrated in a shopping scenario.
