An ontology-supported web focused-crawler for Java programs

This paper proposed an ontology-support web focused-crawler: OntoCrawler III for Java programs, in which only the user entered some keywords would the system supported by the domain ontology actively provide comparison and verification for those keywords so as to up-rise the precision and recall rates of webpage searching. This technique has practically been installed in Google and Yahoo search engines and furthermore searched and filtered out unduplicated and related Java open source webpages and accordingly downloaded and stored the results into a database to let the backend systems to do advanced processes. The preliminary experiment outcomes proved the OntoCrawler III based on ontology-supported techniques proposed in this paper could not only really up-rise the precision and recall rates of webpage searching but also should successfully download related webpage information.
