An Implementation of Semantic Web System for Information retrieval using J2EE Technologies.

摘要

Accessing web resources (Information) is an essential facility provided by web applications to every body. Semantic web is one of the systems that provide a facility to access the resources through web service applications. Semantic web and web Services are new emerging web based technologies. An automatic information processing system can be developed by using semantic web and web services, each having its own contribution within the context of developing web-based information systems and applications. This combination, called Semantic Web Services (SWS), provides several potential opportunities and challenges in ebusiness. Web services provide a verity of dynamic services for accessing web resources, but until now, they have been managed separately from conventional web contents resources. A new system is proposed here for a semantic web information retrieval, which incorporates semantic web, web services and J2EE technologies to enable dynamically locate the web resources that include homogeneous or heterogeneous web contents and web services. In this multi-tier architecture system the middle tier components contains the semantic web services.
