【Abstract】 In order to integrate and query irregular and dynamic information on Web in a database like fashion, we use Object Exchange Model (OEM) to construct information model of Web. In order to express each component of pages as an OEM object, this paper designs an arithmetic which extracts semistructured data from HTML pages, shows testing results.
