Design and implementation of domain-oriented intelligent search engine

摘要

Traditional topic-specific search is difficult to meet the needs of a wide range of vertical intelligent search.Topic-specific search and semantic search technologies are applied to the data collection and intelligent inquiry process respectively.Specifically,this paper uses the domain data collection robot based on hierarchical classification model to gather the domain information.Besides,based on Chinese Encyclopedia Resource,a domain-ontology is built automatically,and is applied into semantic inference and query expansion of search engine,so a domain-oriented intelligent search engine is proposed in order to achieve professional and intelligent search.The results show that,the hierarchical classification for domain has a more high precision and recall rate,and this system has many advantages compared with other search engines,such as highly specialized domain,easy to transplant,more intelligent and so on.
