The Research Of The Distant Education Knowledge Management Platform

The Modern Distant Education Knowledge Management System provides a robust software platform and rich coursewares for distant network training, which provides a new way for cadre study. It will update cadre's study concepts and enhance their knowledge and abilities.This dissertation designed and completed the full-text search engine module with java technology, also did some researches on concurrent user number of the system. The full-text search engine is the most important method for resource searching and locating. With this technique, the user simply submits the searching keywords and the engine will find all the related resources ordered by a pre-determined match degree. The full-text search process implemented in this dissertation is as follows: first, design a java class with the classic "mechanical matching method" for the Chinese word segmentation, then, use this class to perform segmentation on the description field of every resource in the database, and insert the results into the index table. When the user submits his searching keywords, also the class makes the segmentation into single word and matches each word of jiansuo table. The results are ordered according to the matching degree. The function of separating pages is also completed. As for enhancing concurrent users, I have done same research in database design, program design and middle ware configuration.Chapter 1 and chapter 2 introduce the purpose and functions of the system. Chapter 3 introduces the system architecture and some related techniques. Chapter 4 interprets the module design ideas, the Chinese word segmentation strategy, the matching degree algorithm and sorting, then a detailed implementation is given. Chapter 5 proposes a design to enhance the concurrent user number. Chapter 6 introduces the application of full-text search in this project, proposes some ideas to improve the module performance, such as match degree algorithm and synonym search, especially the effects of full-text search in data mining.
