Abstract

At the present time, systems dedicated to information retrieval/extraction perform an important role fetching relevant and qualified information from the World Wide Web (WWW). The Semantic Web can be described as the Web’s future, once it introduces a set of new concepts and tools. For instance, ontologies are being used to insert knowledge into contents of the current WWW, giving meaning to such contents. This allows software agents to better understand the Web’s content so that such agents execute more complex and useful tasks for users. This work introduces an architecture that uses some Semantic Web concepts allied to Regular Expressions (REGEX) in order to develop a system that retrieves/extracts specific domain information from the Web. A prototype based on such an architecture was developed in order to find information about offers announced on supermarket Web sites.
