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

Process mediation

• Process Mediation– Anticipate and provide processes

to handle ordering constraints between mediated parties

• Semantic Mediation– Large semi-automated message

format and term mapping system – Mappings are necessarily

PARTIAL– Teams of people to maintain them

due to continuous version changes

Relevant Agent Architectures to Consider As Participating in the Semantic Web

• FIPA

• CoABS 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 W3C WS Architecture

• Build some small feasibility prototypes– Tools is the key issue

Possible Architectural Use Cases Interacting w. traditional web services

(Amazon, Travel, Shopping) C2B2B, composed C2B

Large-scale B2B commerce
