Design And Application Of Educational Resource Retrieval Based On Trie Tree Algorithm

With the rapid development of the Internet,the Internet has become an important way of education and learning needs people access to educational resources,the development of Internet technology has opened up the distance education development of new areas of growth.Digital educational resources are one of the basic elements of Modern Distance Education in China.Digital educational resources bear the dual functions of remote teaching support and service.But because the education resource is not increased,the real effective information to be fully extracted,will lead to difficult to find educational resources,students and educators work efficiency is low,to solve this problem,first of all need a retrieval system is very effective and feasible education resources.Based on the existing educational resources retrieval system and search engine technology research system based on the design of a technical system to retrieve the Trie Tree algorithm based on educational resources,educational resources,efficient and accurate retrieval of the target,the specific function is mainly:1)education resources management,resources will be increasingly large in a unified platform management education will.(2)intelligent retrieval,on the basis of the semantic identification of educational resources text,according to the user type different keywords to provide users with different search Association tips.(3)query fault tolerance and fuzzy query.(4)relevant recommendation,according to the user query results,recommend the relevant educational resources that may be needed to the user.Intends to use the Visual Studio 2013,SQL Server2008 Trie Tree tool to develop educational resources retrieval system based on the algorithm,the key steps include:(1)the document data source(2),inverted index establishment and compression(3),inverted index update,(4)the inverted index based on searching,(6 Trie)Tree search based on Lenovo,(7)the query error tolerance and fuzzy query,search ranking design(8).After the completion of the system test,the educational resource retrieval system based on Trie Tree algorithm has completed the established functional requirements and performance requirements.Effective management of educational resources to improve the availability of many educational researchers concern,design and implementation of retrieval system Trie Tree algorithm based on education resources,has certain practical significance to solving this problem;at the same time,the design and Realization of this system will greatly improve the students and educators work and learning efficiency.
