The AIFB Web Portal is the public web site of the Institute of Applied Informatics and Formal Description Methods (AIFB) at Karlsruhe Institute of Technology. It uses Semantic MediaWiki to provide a highly customised Content Management System. The site provides content in two languages (German and English), and it offers rich views for browsing different kinds of data. The content of the AIFB Web Portal is regularly edited by most members of the institute, from secretary to professor, but it is not open for public editing.

YAGO is a huge semantic knowledge base. Currently, YAGO knows more than 2 million entities (like persons, organizations, cities, etc.). It knows 20 million facts about these entities. Unlike many other automatically assembled knowledge bases, YAGO has a manually confirmed accuracy of 95%. YAGO is part of the YAGO-NAGA project at the Max-Planck Institute for Informatics in Saarbrücken/Germany.

"Ontologies are formal descriptions of the world encoded in a "computational logic". The Web is the largest information structure in the world encompassing everything from a substantial part of the world economy to the fluffiest of emphemera. When the tidy world of logic hits the sprawling mudball of the web, the result is the W3C's Web Ontology Language, OWL."

Twarql - Streaming Annotated Tweets project ("twarql") In this project we investigate the representation of tweets as RDF in order to enable flexibility in handling the information overload of those interested in collectively analyzing social media for sensemaking.
