| Abstract: | This paper presents a construction method for vertical search engine utilizing ontology filtering and text mining towards existing problems in the domain.Firstly,it discusses ontology and text mining as well as their applications.Then,we provide a set of key techniques for the construction of vertical search engine which include ontology-based Web crawling,Web page analyzing combined with text mining,indexer and searcher constructing.Finally,an evaluation of our proposed ideas is presented by implementing a prototype of job hunting search engine towards college students.[JP |
