Abstract
This paper discusses some of the issues in Web information extraction, focusing on automatic extraction methods that exploit wrapper induction. In particular, we point out the limitations of traditional heuristic-based wrapper generation systems, and as a solution, emphasize the importance of the domain knowledge in the process of wrapper generation. We demonstrate the effectiveness of domain knowledge by presenting our scheme of knowledge-based wrapper generation for semi-structured and labeled documents. Our agent-oriented information extraction system, XTROS, represents both the domain knowledge and the wrappers by XML documents to increase modularity, flexibility, and interoperability. XTROS shows good performance on several Web sites in the domain of real estate, and it is expected to be easily adaptable to different domains by plugging in appropriate XML-based domain knowledge.
