SemanticPeer: An Ontology-Based P2P Lookup Service
نویسندگان
چکیده
Locating content efficiently and conveniently is the key issue in P2P systems. In this paper we present SemanticPeer, an Ontology-Based P2P lookup service, to address this problem, which is an extension of Chord protocol. In SemanticPeer, one can easily locate desired data items using the domain knowledge, beyond the keywords scheme. By the separate of share knowledge and private knowledge, SemanticPeer provides a high degree of node autonomy. SemanticPeer clusters the documents according to the domain knowledge, so we can answer a query with a specified characteristic efficiently.

SPiDeR: P2P-Based Web Service Discovery
In this paper, we describe SPiDeR, a peer-to-peer (P2P) based framework that supports a variety of Web service discovery operations. SPiDeR organizes the service providers into a structured P2P overlay and allows them to advertise and lookup services in a completely decentralized and dynamic manner. It supports three different kinds of search operations: For advertising and locating services, s...
متن کاملSemantic Lookup in Service-Oriented Architectures
Lookup of services is an important issues in many distributed systems. This paper deals with lookup in service-oriented architectures, such as Web services, P2P systems, GRIDs, or spontaneous networks. Service-oriented architectures impose specific requirements onto the lookup service, for instance regarding the runtime extensibility of lookup models, runtime extensibility of lookup queries, co...
متن کاملA Case for Locally-Organized Peer-to-Peer Lookup Services
Distributed lookup services have predominantly fallen into one of two categories: Gnutella-based systems and DHTs. In this paper, we identify a set of applications for P2P lookup services, and analyze each of their requirements along a commonlychosen set of dimensions. We show that neither Gnutella nor DHTs may provide the desired tradeoffs among these dimensions. We go on to demonstrate a loca...
متن کاملA Peer-to-Peer Approach to Semantic Web Services Discovery
Web Services with distributed and dynamic characteristics need efficient and decentralized discovery infrastructure supporting the semantic descriptions and discovery. In this paper, a novel peer-to-peer indexing system with related P2P registries is proposed to support the completely decentralized discovery capabilities. In the presented system, with the ontology encoding scheme, the semantic ...
متن کاملA Testbed-based Analysis of the Incorrect Lookup Routing Attack on the Pastry DHT
Distributed Hashtables (DHT), with Pastry [2] as a prominent representative, are one of the most recent peer-to-peer (P2P) architectures. DHTs scale well to the network size due to a small routing table and a hierarchical routing scheme. In Pastry, the number of routing entries scales logarithmically with respect to the number of participating nodes, because each node maintains route entries to...
