The prototype we describe is a biomedical knowledge base, constructed for a demonstration at Banff WWW2007 , that integrates 15 distinct data sources using currently available Semantic Web technologies such as the W3C standard Web Ontology Language [OWL] and Resource Description Framework [RDF]. This report outlines which resources were integrated, how the knowledge base was constructed using free and open source triple store technology, how it can be queried using the W3C Recommended RDF query language SPARQL [SPARQL], and what resources and inferences are involved in answering complex queries. While the utility of the knowledge base is illustrated by identifying a set of genes involved in Alzheimer's Disease, the approach described here can be applied to any use case that integrates data from multiple domains.

Europeana - the European digital library, museum and archive - is a 2-year project that began in July 2007. It will produce a prototype website giving users direct access to some 2 million digital objects, including film material, photos, paintings, sounds, maps, manuscripts, books, newspapers and archival papers. The prototype will be launched in November 2008 by Viviane Reding, European Commissioner for Information Society and Media.

DynaQ stands for 'Dynamic Queries for document based, personal information spaces'. The goal of the project is to conceptualise and to develop a prototypical inquiry system to explore the personal information space, that supports the user with the help of the searching paradigm orienteering. The document-based, personal information space of the user constitutes by all documents on his computer. Included are documents of several file formats (e.g. *.pdf), but also the users emails. Also included are all available meta informations and existing semantic informations according to the documents. Users that are not aware of the scientific context of the project can just think of DynaQ as an desktop search engine.

SMOB is a distributed / decentralised microblogging system built on RDF and Semantic Web technologies, mainly SIOC and FOAF. Currently, we have simple prototypes of a publishing and an aggregating service, less than 100 lines of PHP code each. Code at http://code.google.com/p/smob/

OntoWebber is a Web site management system, which facilitates the creation, generation and maintenance of Web sites. Using OntoWebber, site engineers can build site models for domain-specific Web sites. The site models are based on explicit ontologies including the domain ontology and four distinct site-modeling ontologies. Using a RDF-aware rule engine, rules can be defined to check integrity constraints on the resulting site models, thus enforcing desirable properties of the materialized Web site. Both ontologies and site models are expressed using RDF(S)/XML languages. Rules are defined in the F-logic format. The prototype system provides an Integrated Development Environment (IDE) for site engineers to performed all the above tasks for managing Web sites.

PowerMeeting is a Web-based synchronous groupware framework. It also refers to a research prototype that demonstrates the kind of groupware built with the framework. Such groupware allow participants to plan, perform, and coordinate their synchronous collaboration.

The YAGO-NAGA project started in 2006 with the goal of building a conveniently searchable, large-scale, highly accurate knowledge base of common facts in a machine-processible representation. We have already harvested knowledge about millions of entities and facts about their relationships, from Wikipedia and WordNet with careful integration of these two sources. The resulting knowledge base, coined YAGO, has very high precision and is freely available. The facts are represented as RDF triples, and we have developed methods and prototype systems for querying, ranking, and exploring knowledge. Our search engine NAGA provides ranked answers to queries based on statistical models.
