ICT and BusinessICT and Business
• Networks (e.g. Internet) enabling many-to-many interactions beyond physical boundaries
• The very essence of business is about enabling people to interact to create value
• e-Business deals with similar subjects (collaborative commerce, supply chain management, e-markets, networked organisations dynamic trading networks)organisations, dynamic trading networks)
• Evolution is driven by:– The need for Industry consolidation– The requirement to move closer to customers, suppliers and partners– The growth of e-commerce – change “conventional” business models– The formation of “common interest” communities

Component/Service-oriented Architecture and semantic interoperability
• Repositories and software systems are programmatically accessed by business processes
• The definition of interfaces and their access at runtime is not uniform at all
• Every enterprise uses different technology for the programmatic accessW b S i d if d i l• Web Services are proposed as a uniform and universal technology for this problem

The Rationale of P2PThe Rationale of P2P• Discovery of resources (e.g.
N G ll )Napster, Gnutella)– What about security?
• Eliminating the single source• Eliminating the single-source bottleneck – Use P2P search capabilities to– locate Web service registries– and also individual not registered
servicesservices• The enterprise can now
participate in B2B marketplaces d di tl ll b t ith itand directly collaborate with its
suppliers

Turn networked Business standards more flexible through Semantics
Thi b ibl b i t d i ti t• This can be possible by introducing semantics to Web services:
f– By classifying Web services with well-known taxonomies, ontologies and controlled vocabulariesvocabularies
• management, retrieval and use easier and more accurate
– By introducing semantics to the messagesBy introducing semantics to the messages exchanged

Summary and discussionSummary and discussion
• From the Infrastructure Provider viewpoint: A Semantic Web Service based toolkit using P2P discovery mechanisms to locate the Web service registries and Web services
• From Business User viewpoint: Tools that facilitate the advertisement and discovery of their Web Services especially for SMEs
• From End User viewpoint: Easy discovery,From End User viewpoint: Easy discovery, composition and invocation of services
