Semantic web search engines can take advantage of machineunderstandable data published on the Web to provide more precise search results and advanced query capabilities. Semantic data embedded in web documents (serialized as RDFa or microformats, for example) can be used in conjunction with a semantic web search engine to provide a better web navigation experience. We present Semantic Navigator...

Semantic Web is an extension of the current Web. It gives the existing Web content a well-defined meaning: enabling machines understand and process semantic information, and cooperate with humans to realize the full potential of the Web. In this paper, we give a general description and discuss the role of each layer of the Semantic Web architecture, and compare Semantic Web and the XML based We...

In this paper, we present an approach, called RS2D v1, to adaptive probabilistic search for semantic web services in unstructured P2P networks. Each service agent dynamically learns the averaged queryanswer behavior of its neighbor peers, and forwards service requests to those with minimal mixed Bayesian risk of doing so in terms of estimated semantic gain and commmunication cost. Experimental ...

Learning technologies have already started to make use of both Social Web (or Web 2.0) and Semantic Web principles, techniques, approaches and tools. Recently, researchers and developers have started to combine these two worlds, thus giving rise to the Social Semantic Web. Consequently, the world of learning technologies turns itself more and more to the Social Semantic Web as one of its key su...

The paper discusses an approach for facilitating the authoring process for Technology Enhanced Learning by providing service oriented access to learning materials based on their content. This service-oriented approach is based on Semantic Web Service technologies. It reflects current work in the frame of an ongoing Bulgarian research project SINUS “Semantic Technologies for Web Services and Tec...

In this paper we present a Semantic Web application (http:// uranos.khaos.uma.es/atfast), which is based on a Semantic Web infrastructure (NEMESIS). This application is a Semantic Web graphical tool used for analyzing transcription factor databases. NEMESIS not only solves several problems of the Semantic Web but is also a generic infrastructure for the Semantic Web. This infrastructure, togeth...

Web search engines are designed to retrieve and extract the information in the web databases and to return dynamic web pages. The Semantic Web is an extension of the current web in which it includes semantic content in web pages. The main goal of semantic web is to promote the quality of the current web by changing its contents into machine understandable form. Therefore, the milestone of seman...
