Abstract

Information retrieval services on the Internet have tried to provide Internet users with information processed as the way users want. These information retrieval systems merely show html pages that include the index word abstracted from the user's query. There are a number of difficulties to be overcome in the present technology which could be solved by considering semantics in html documents. However it can heighten the precision of retrieval results by using the structural information of the document as an alternative source of information. The tabular form, which appears on ordinary documents, usually has the most relevant information. Based on the similarity to a Web's html document, we try to improve the precision of results by analyzing the table on html documents. Our main purpose here is to do table parsing and construct a dictionary of table indexes for applying to our information retrieval system and thus enhance the accuracy.
