Abstract

We propose a new web information extraction system, PIES, to convert web information into XML documents. PIES uses a user-specified ontology and HTML tag pattern descriptions. The ontology validates the web information the pattern descriptions extract. We designed a new language to describe HTML tag patterns and extraction rules. We implemented PIES and applied it to the US patent web site for evaluation.
