User-intent custom adaptive search service based on ontology and similar-word retrieval algorithm composition

The most important aspect of information retrieval function provided search engine is that finding results correct reflecting information searcher's intention. This point is related relevance to decide how useful search result is a important criterion of assessing search engine. The standard of relevance is divide into precision which means how system finds related documents accurately, and recall that sense does it finds all related documents well. Most studies researched review for search engine of improves performance but from the user perspective can cause different satisfaction to relevance of search result depending on search engine or algorithm usage. Not only the performance of algorithm and research engine but also understand the intent of users then adapt this to interface and presenting to users can be an important research for increasing the satisfaction of research reusal. The research suggested to satisfy user's intention that designing ontology and user experience-based search algorithm and implementing interface with comply to user way to provide the best research result
