Seminar Thursday 13 July at 4:15 in 1W 3.6 Title: OpenKnowledge and interaction model language. Sindhu Joseph iiia.csic.es In this talk I will be discussing about a European project that I am participating currently. I'll talk about the general aims and motivations, the main research questions the project aims to address, and explain the role of interaction protocols in the context. Following is the abstract taken from the project proposal. The existing, open Worldwide Web has been successful on a global scale because the cost of participation at a basic level is low and the individual benefit of participation is immediate, rising rapidly as more participants take part. The same cannot currently be said about semantic based systems because the cost of being precise about semantics for sophisticated components is prohibitively high and the cost of ensuring an individual, absolute semantics for a component rises rapidly as more participants take part. OpenKnowledge aims to break out of this deadlock by focusing on semantics related to interaction (which are acquired at low cost during participation) and using this to avoid dependency on a priori semantic agreement; instead making semantic commitments incrementally at run time. A key contribution OpenKnowledge hopes to realize is that by shifting the emphasis to interaction (the details of which may be hidden from users) we can obtain knowledge sharing of sufficient quality for sustainable communities of practice without the barrier of complex meta-data provision prior to community formation. We ground our research in two testbed arenas: bioinformatics and emergency response.
