Design And Research Of Campus Information WeChat Service Platform Based On Vertical Search Engine

With the development of information technology and the advancement of university informatization,all universities have established their own digital campus information service systems.Most of the traditional digital campus information service systems are based on B/S architecture development which is equipped with relative good compatibility,and the user can have data interactions through the computers or intelligent terminal systems.Under the promotion of the 4g network,the user can through a smartphone to do most of business operations which could only be done by the computer in the past.Apart from that,the functions of the smartphone can be expanded in terms of the application of APPs,providing more humanized services for the users.And the leading instant messaging softwares such as QQ,WeChat have became the essential APPs of a smartphone.All above inventions have changed people's way of living for they could improve the efficiency of business which provides much convenience for the extensive number of students and teachers.Campus WeChat platform based on the technology of vertical search engines,to be frank,is to inject digital campus information into WeChat public platform,and to build vertical search engine crawler system for digital campus which is based on the particularity of campus environment for a vertical search function.Through the crawler system to realize the unity of the each system of digital campus information retrieval,and to unify every page into campus WeChat working platform,so as to realize a unified portal and a unified authentication.The campus information platform designed by the researching project,using PHP,MySQL,Linux Bash Shell and some other technologies for secondary development of WeChat ID and using cloud services to build server as a point of contact data transmission,through which the WeChat client,WeChat server,and campus data among various information system can interact efficiently.Besides,the platform can analyze and summary the data analysis of the user request by the MemCache technology frequently accessed data to form pile and reduce the user waiting time for data returned by the response.The functions of information retrieval has used the web crawler system which is based on the technology of vertical search engines to design the work the web crawler in a flow way,and optimize the extraction algorithm of the keywords insides the web crawler,so as to realize the optimization of retrieval sort,making the searching more professional and more accurate.
