Potential Requirements for SWS (the big picture) For WS, interpretation of XML seems essential. • For SWS, Agents must be able to: – Interpret OWL (or equiv) • Or bridging by providing semantics for non-semantic agents – Incorporate of new classes, descriptions dynamically – Formulate goals that can be satisfied by discovery (or possibly composition) of remote services – Access internal knowledge to supply information required for service requests (e. g. credit card info) – Utilize internal or external translation capabilities
WSMF and Oracle EI approach Internet SWIFT WSMF VAN
Content and Process Mediation Internet • Process Mediation SWIFT WSMF VAN – Anticipate and provide processes to handle ordering constraints between mediated parties • Semantic Mediation SAP POA S E M A N T I C MAP ING OAGIS PO OAGIS ACK OAGIS POA OAGIS ACK Process mediation 4/3/2003 – Large semi-automated message format and term mapping system – Mappings are necessarily PARTIAL – Teams of people to maintain them due to continuous version changes 4
Relevant Agent Architectures to Consider As Participating in the Semantic Web • • FIPA Co. ABS Grid Cougaar Retsina OAA Scientific Grid …
Architectures for Semantic Integration (Whose ontologies are these anyway? ) • Holy Grail: Ontological Negotiation • Status Quo – (manual mappings, limited interlingua…) • • Global Ontologies Manual Mapping Interlingua Ontologies Community Ontologies
Near-term Objectives • Develop full use cases in different environments, domains – Use cases with people interacting with services and not, providing ontology maintenance support at different points in the architecture • Review and determine feasibility of building on top of W 3 C WS Architecture • Build some small feasibility prototypes – Tools is the key issue
Possible Architectural Use Cases 1. Interacting w. traditional web services 1. (Amazon, Travel, Shopping) C 2 B 2 B, composed C 2 B 2. Large-scale B 2 B commerce 1. like Oracle EI 3. Pervasive Computing 1. Smart space environment 1. services appropriate to a room 1. convert a file to make it printable, then print it 4. My. Grid computing 1. Semantics for long-lived distributed computing
