MIWeb: Mediator-based Integration of Web Sources
نویسندگان
چکیده
MIWeb realizes a mediator-based integration of heterogeneous metadata sources over the Web. Mediators are well known from database integration. They improve the quality of search results by providing a query language, by automatically coupling sources, and by filtering redundant results. The MIWeb system contributes mediator architectures in the context of Web sources, metadata standards for integration by using modern web technologies. MIWeb supports the search for learning materials and related publications. It is based on in-house learning object sources, the search engine Google, and the research index CiteSeer. Technical the integration layer uses technologies like HTTP, RDF and the RDF query language RDQL.

متن کاملUsing Agents for Generation and Maintenance of Mediators in a Data Integration System on the Web
In this paper we present a system for data integration on the web, where an XML-based mediator plays a key role providing a homogeneous view of different data sources. One novelty of our approach is that we also propose solutions for the problems of generation and maintenance of mediators. Observe that, in dynamic environments, such as the Web, individual data sources may change not only their ...
متن کاملA View Integration Approach to Dynamic Composition of Web Services
Web services enable the user to integrate and manipulate data from distributed data sources without worrying about the underlying syntactical details. We describe extensions to the view integration approach to support dynamic integration of data from web services and support dynamic composition of web services from existing web services. In particular, we describe techniques to extend the “inve...
