At present, Internet has already been the main medium of the world, and the information on the Internet expands with the explosive speed. How to get the network resource effectively according to the user's intention has become a very important and urgent problem. Rational information retrieval mechanism will be able to improve the user's availability factor, but because these systems at present are based on keyword, and return with large amount of useless information sometimes. So it costs a great deal user's time to eliminate the useless information, so the recall factor and pertinency factor cannot get the request of users. It becomes a hotspot to seek the intellectualized retrieval way.During the past years, for the hiberarchy of conception, supporting reasoning, ontology-based information retrieval has become import study task. Considering the complicated degree of designing Ontology, so I choose the fire fighting area to build ontology. The article introduces the background and interrelated concepts of information retrieval system and Ontology first, then advance the framework of the Fire Fighting Information Search System. At last realizes inquiring about information retrieval with realizing systematic semanteme in fire control equipment area.The research content of this thesis includes the following several aspects:(1) Advance the framework of the Fire Fighting Information Search System by analyzing common Information Search Systems. Design and elementary realize this model that aim at semantic query.(2) Be familiar with knowledge of fire control field, build the ontology of fire fighting, and realize permanence by OWL.(3) Integrate the popular information search systems and compare them with Fire Fighting Information Search System. Provide individuation searching system service. |
