Here you can find some demos showing OpenKnowledge at work in various different fields. Please note that demos explaining how the kernel works and how you can become an OK user can be found on the downloads page.

• The SemanticLogger is a system for the unobtrusive capturing of autobiographical metadata, and has been completely ported to OpenKnowledge. The archived metadata is then used to drive Photocopain, an automatic image annotation service. The demo is described in Deliverable 5.5.
• The emergency response demo illustrates the work done in this testbed. Further details can be found on the case studies page and Deliverable 6.8.
  (This demo is not available yet. This should be on the webpage on November 24th)
• PowerAqua is a multi-ontology-based Question Answering (QA) system, which takes as input queries expressed in natural language and is able to return answers drawn from relevant distributed resources on the Open Knowledge Peer to Peer infrastructure. In contrast with any other existing natural language front end, PowerAqua is not restricted to a single ontology and therefore provides the first comprehensive attempt at supporting open domain QA on the Semantic Web.

• OKOmics is a system for sharing sequenced MS spectra between proteomic laboratories. Using this system, proteomic researchers can send proteomic queries to multiple laboratories and compare the results.
