| Xinjiang corps of Chinese Armed Police Force developed an answer system of training and management in 2006. After operation, the system resolved, to a great extent, some problems which the officer of the frontline troops encountered in the training and management. However, under the new era, the continual emergence of new ideas and situations takes big difficulties to the existing management. Obviously, relying solely on the answering system has been unable to meet demands. The research, which make the answer system to achieve the tree-tier network resource library expansion using that search engine collect the information in the three-tier network, must not be delayedAt present, there are still many limitations of the search engine. Users hope that the search results will meet demands, under search engine ensuring efficient. To solve this problem, the paper researches the search engine-related technologies based on the concept. This paper studies mainly:(1) Search Engine Technology. The paper sums up the history of the development of search engine, analyzes the working principle of search engine, decrypts the key search engine technology, analyzes the reason on that search results of the current search engine is not fine.(2) Construction of semantic network. The paper introduces the methods of the construction of semantic network, proposes the model of semantic network and knowledge representation of semantic network. In the paper semantic network based on the concept is designed and realized, and the maintenance of the concept database is realized.(3)In the paper the overall framework of the search engineer system is resigned, the Implementation is presented. And Generation Index and search based on the concept are realized. At last, search engine application of this model to answer the system is explained.At last the paper summarizes the work done, proposes the questions of the studies, outlooks the future of the search engine technology... |
