چکیده

In Peer-to-Peer data sharing systems, peers typically play equal roles and have equal capabilities. From the service perspective, peers provide a single service. For this reason, there is no need to explicitly model services. We argue, that for knowledge sharing systems, we need an effective combination of the capabilities of the peers both in terms of the services as well as the content they provide. In this paper we present an approach for modeling peers with content and service capability descriptions that allows a decentralized discovery and selection of peers. We show instantiations for various kinds of bibliographic services that are realized in the Bibster system, a semantics-based Peer-to-Peer system for sharing bibliographic metadata.

Using Multi-Agent Based Middleware to Implement a Distributed Peer-To-Peer Semantic Service Oriented Architecture

In this work we give the outline for a novel approach to semantic web service based applications. This approach centers around the use of so-called intelligent agents as the basis for the middleware layer. We give a broad outline of our prototype architecture and preliminary correctness results.

Peer-to-Peer Semantic Web Services: A Symbiotic Relationship for Knowledge Sharing

The building of complex information systems got a big boost with the advent of service-driven architectures. However, at present, service architectures look beyond standardize remote procedure calls and textual directories to locate and describe a service provider based on human intervention. In this paper we consider three important paradigms for building next generation service-driven systems...

Enabling semantic search in P2P systems through a three-layer Distributed Service Registry

Effective searching and access to data and functionalities in P2P environments require platform independency for integrating different sources over the Web and must take into account the presence of high dynamicity and the absence of a common resource conceptualization. Service Oriented Architecture enables to export shared data and functionalities through Web Services, thus enabling platform-i...
