2. November 2005SNAC2 Semantics in and on the Grid The Semantic Grid is an extension of the current Grid in which information and services are given well-defined meaning, better enabling computers and people to work in cooperation

3. November 2005SNAC3 The Semantic Grid challenge my Grid Combechem Wish to reuse –Data –Services –Knowledge –Software –Practice Anticipated use Unanticipated use

4. November 2005SNAC4 New ways of discovery: e-Science A large part of scientific discovery is now a joint human machine endeavour Distributed, collaborative community endeavour Virtual organizations include people With this will come new ways of accessing and understanding results We need new tools and methods to understand the knowledge landscape

5. November 2005SNAC5 Message Using community to map knowledge Using knowledge to map community e-Science is a distributed, collaborative community endeavour, i.e. virtual organizations We need to focus on both…

14. November 2005SNAC14 The CS AKTive Space: International Semantic Web Challenge Winner 24/7 update of content Content continually harvested and acquired against community agreed ontology Easy access to information gestalts - who, what, where Hot spots –Institutions –Individuals –Topics Dynamic Communities of Practice… Impact of research –citation services etc –funding levels –Changes and deltas

15. November 2005SNAC15 AKT Community of Practice Tool Based on the AKT reference ontology Integrates a range of information from different sources – mediated via the ontology Can see the CoP change through time Can have CoPs of people, projects – any object in the ontology NB FOAF

16. November 2005SNAC16 Summary e-Science is a distributed collaborative community endeavour –Community maps knowledge –Knowledge maps community Semantic Web technologies facilitate both –Social networks for virtual organizations Cyberinfrastructure environments need tools to study and support communities of practice
