The Design Of SMS-based Mobile Search System And The Research Of Its Implement Techniques

With the fast development of mobile communication and search engine, mobile search attracts more and more attention. It combines mobile communication technology with search engine and enables mobile phone users to search the Internet and obtain relevant information at any time and any place they want. Thus, mobile search do has important worth of application and significant applied space.This paper focuses on real use. According to the particularity of mobile search system, it chooses a suitable mode to show the result for mobile users. Our SMSBMS system's service orientation is: providing short information retrieval for mobile users and optimizing the service of frequent search. Then we finish the request analysis of SMSBMS system.According to the service orientation and request analysis of the SMSBMS system, we designed the whole structure of the system and divide the system into five modules: (1) the meta search engine module to obtains system data. it adopts genetic algorithm in schedule strategy to improve the quality of system data source, (2) the local store module to manage the web snapshot content of frequent words, this can reduce the system complexity, saves store space. Meanwhile it accelerates the search process by cache.(3) the Chinese word segmentation module to support the text segmentation of system, it uses HMM-based disambiguation algorithm to improve the accuracy of the word segmentation.(4) the search module to response the users'search request, it applies an efficient clustering/classification algorithm to optimize the search service quality. (5) the communication interface module to transfer data with short message gateway. It follows to the protocol of CMPP3.0. Besides, according to the request of modules'function and real technique, we gave the design of relevant tables'structure of SMSBMS system.At last, we implement those designs on PC. The results of simulate test showed that: the SMSBMS system can quickly and efficiently provides short information retrieval service for the mobile users, satisfied the expectation.
