英文摘要	This paper proposes an ontology-driven self-adapting approach in semi-structure web information extracting field, where ontology provides semantic support and plays a central role during the extraction process. It excels traditional wrapper systems at adaptiveness and maintenance. Firstly, we build a domain-dependant ontology. Then we design three templates generating algorithms, which have self-adaptiveness and self-maintenance based on the ontology, to perform the web page information extraction. Experiment results show that our prototype system can achieve 100% recall & 97.64% precision. ? 2003 IEEE.; EI; 0
