Domain-Oriented Retrieval Model Research Based on Meta-search
In allusion to the complex information resource and more and more difficulty of retrieval for the user,this paper present a new retrieval model based on the Meta-search.It associates the user retrieval interface with the domain-specific knowledge base which produce the domain-specific formula and the standard formula as the input of general search engine,at last,by means of meta-search dispatching module and document sorting module adopting Extended Boolean Model,it will return the sorted document set according to the correlativity degree.The experiment proves efficient in satisfying the users query request.
