Query Form Analysis of Search Sites in Meta-Search System DAISEn

摘要

DAISEn is a meta-search engine generation system which integrates specialized search engines dynamically. Meta-search engines, in general, require a program to deal with a different format of query for each site. DAISEn analyzes the query format of the search page and generates a wrapper automatically. As an empirical evaluation of DAISEn, the present paper evaluates the extraction of the query formats of 2882 search sites registered on NDL Database Navigation Service Dnavi.
