【Abstract】 Illustrating the constituted modules of search engine and the relation of these modules. The fundamental algorithms are reconstructed according to the characteristics of the railway information. The design needs the following technologies: natural language processing technology, search robot technology and the Chinese and English index technology. The purpose of design is to provide users with a quick, efficient and exact search tool at the railway information shared system. This search engine is able to provide the indexes of all the railway information, and users could search the needed data through the intelligent user interface.更多还原
