As researchers continue to create new languages in the hope of developing a Semantic Web, they still lack consensus on standard. The authors describe how Protege-2000, tool for ontology development and knowledge acquisition, can be adapted editing models different Web languages.
Metadata for the World Wide Web is important, but metadata Peer-to-Peer (P2P) networks absolutely crucial. In this paper we discuss open source project Edutella which builds upon standards defined WWW and aims to provide an RDF-based infrastructure P2P applications, building on recently announced JXTA Framework. We describe goals main services will architecture connect Peers based exchange of RDF metadata. As query service one core Edutella, other are built, specify in detail Common Data...
To meet the growing need for enterprise-wide knowledge management, authors have developed and fielded a three-layered model processing knowledge. This article shows how their organizational memory serves as an intelligent assistant deals with both formal non-formal elements in task-oriented fashion.
Personalized support for learners becomes even more important, when e-Learning takes place in open and dynamic learning information networks. This paper shows how to realize personalized distributed environments based on Semantic Web technologies. Our approach fills the existing gap between current adaptive educational systems with well-established personalization functionality, open, repository We propose a service-based architecture establishing e-Learning, where functionality is provided...
Semantic Web Services are a promising combination of and service technology, aiming at providing means automatically executing, discovering composing semantically marked-up services. We envision peer-to-peer networks which allow for carrying out searches in real-time on permanently reconfiguring to be an ideal infrastructure deploying network Service providers. However, P2P evolving unorganized manner suffer from serious scalability problems, limiting the number nodes network, creating...
Databases have employed a schema-based approach to store and retrieve structured data for decades. For peer-to-peer (P2P) networks, similar approaches are just beginning emerge. While quite few database techniques can be re-used in this new context, P2P management infrastructure poses additional challenges which solved before networks become as common databases. We will describe some of these discuss solve them. Our discussion based on the design decisions we our Edutella infrastructure,...

<div class="abstract_container"> <strong>Abstract:</strong> Selecting appropriate learning services for a learner from the large number of heterogeneous knowledge sources is complex and challenging task. This paper presents idea Smart Spaces Learning. A Space Learning defined as distributed system (ie "space") that provides management support "smart" retrieval consumption via Personal Assistants. Personalisation interoperability play an important role realisation In this we illustrate...
Medical CBIR (content-based image retrieval) applications pose unique challenges but at the same time offer many new opportunities. On one hand, while can easily understand news or sports videos, a medical is often completely incomprehensible to untrained eyes. other semantics in domain much better defined and there vast accumulation of formal knowledge representations that could be exploited support semantic search for any specialty areas medicine.In this paper, however, we will not dwell...
