Abstract

Information extraction techniques provide automated generation of a structured representation from unstructured or semi-structured content. Structured information enables or facilitates further processing by third-part Web applications. This work describes the implementation of a domain-oriented information extraction system. The system automatically converts semi-structured Web content into structured content, by means of object-oriented production rules that instantiate a specific domain classes provided. These rules are implemented in JEOPS, a Java-based first-order forward chaining inference engine. We have fully specified classes modeling the Brazilian Soccer Championship to show the feasibility of the proposal. Taking as input a Web site address, the system uses facts and rules defined in its knowledge base in order to identify related links, find the championship classification table and extract table data. As a result, it automatically fulfills domain classes’ instances.
