1st International Conference on Semantics, Knowledge and Grid SKG2005 1st International Conference on Semantics, Knowledge and Grid
Introduction David De Roure
Visions e-Science Grid e-Science is about global collaboration in key areas of science and the next generation of infrastructure that will enable it Grid “…flexible, secure, coordinated resource sharing among dynamic collections of individuals, institutions, and resources - what we refer to as virtual organizations” November 2005 SKG2005
Requirements These visions require an infrastructure for flexible, coordinated resource sharing They are about joining resources up, automatically, in order to do things that weren’t possible before We wish to reuse Data, Services, Knowledge, Software Anticipated use and Unanticipated use November 2005 SKG2005
Two infrastructure enablers An automatically processable, machine understandable web Distributed knowledge and information management Information integration On demand transparently constructed multi-organisational federations of distributed services Distributed computing middleware Computational Integration Goble November 2005 SKG2005

Scale of Interoperability Semantic Grid SKG2005 Semantics & Knowledge Scale of Interoperability Classical Web Classical Grid Scale of data and computation November 2005 SKG2005 Based on an idea by Norman Paton
Semantics in and on the Grid Computing The Semantic Web The Semantic Grid Web Services November 2005 SKG2005
Motivation Future visions of computing involve Virtualisation Raising the level of abstraction over scale and heterogeneity of resources This requires automation Self-managing, Self-configuring, Self-healing This requires machine processable descriptions and content This requires semantics and knowledge This requires SKG2005 !
