Research And Implementation Of The Restructuring Of The Network Of Educational Resources

The world wide web (www) is a large distributed hypertext system with hundreds of millions of users and more than 4 million websites nowadays. At present, the resources, e.g., those related to education, from the internet becomes more and more so that it has become a common concern for people to search these information from the web. Search engine technology (SET) makes it possible for one to find the formation of their needs.Recently, a program is being carried out in Guangdong province, called "151" project, in which many related universities and colleges are constructing the web sites, resources and web demonstrated courses related to high educations. In this thesis, we will focus on the study of how to reconstruct these resources and provide a more convenient way for the users. In this project, we designed and constructed the gate website of "151" project and reorganized miscellaneous resources in a more efficient way. Further, we provided many more convenient searching ways, e.g., subject category classification searching and keywords search, in which the keywords searching can collect the webpage information of "151" project automatically, indexing and saving these information, and performing the search based on the keywords provided by the users, and then presenting the corresponding final searching results.An introduction and survey of the development and the features of the classification of SET is outlined in the first and the second chapters. Then, in Chapter 3, the principle of SET is introduced, in which some related techniques, such as search technique, Chinese participle techniques etc. are discussed.In Chapter 4, based on the analysis of he functions of the web portal of "151" project, the structure frame of the web site is proposed and realized.The key technique of the web portal is the realization of the search engine. Hence, in Chapter 5, we described the system structure of the search engine of our web portal and designed its four subsystems, i.e., search, analysis, index, and query subsystems. The key algorithms are also given on how to realize these functions within these chapters.The thesis is summarized at the final chapter, and some proposals are given for future work in developing "151" web portal.
