Information needs becoming more complex and the growing trend to hybrid information processing (human+machine) increasingly require the use of semantic web technologies and port legacy data.

Specific subject areas of the centre of excellence are:

Knowledge Extraction and Storage

• Web-Scale Knowledge Extraction (TAIPAN, FOX, AGDISTIS, OCELOT)
• Federated Queries (Quetsal)
• Large-Scale Storage and Caching (Quetsal, BDE)
• Benchmarking (GERBIL, HOBBIT)

Knowledge Integration and Fusion

• Statistical Relational Learning (LIMES)
• Link Discovery and Fusion (LIMES, DEER)
• Machine learning (EAGLE, WOMBAT)

Knowledge Access

• Keyword Search (SINA, DIESEL)
• Hybrid Question Answering (HAWK)
• Browsing and Interfaces (Ginseng, Onto Wiki)
