Ontology-based HTML to XML conversion
WAIM'05 Proceedings of the 6th international conference on Advances in Web-Age Information Management（2005）
摘要
Current wrapper approaches break down in extracting data from differently structured and frequently changing Web pages. To tackle this challenge, this paper defines domain-specific ontology, captures the semantic hierarchy in Web pages automatically by exploiting both structural information and common formatting information, and recognizes and extracts data by using ontology-based semantic matching without relying on page-specific formatting. It is adaptive to differently structured and frequently changing Web pages for a domain of interest.
