Retrieval Effect Evaluation And Optimal Research On Information Resources Of Network

Technique of information retrieval is a kind of key technique by which to organize and manage information resources and is the center of information resource management .At present, it has become one of important fields which are found research emphasis and fruitful outcomes. It is high time to solve the new question for study on retrieval and utilization of information resources.According to the generalization from a good many documents, we find organization and retrieval of network information resources leave much to be desired.This article makes profound researches into organization of network information resources, retrieval technique of search engine and Chinese network catalogue to make them more reasonable and scientific. Concrete contents are follows:1,Solve the problems of organization of network information resources and retrieval results by information and knowledge integration.2,Set up the optimal model of retrieval technique of search engine. W(IRC)=f[PR,R(P),C(P)]3,Present the optimal scheme of classification system of a guide to chinese network catalogue ,and design a integrated classification system by referring to the traditional classification and experience in classification system of a guide to chinese network catalogue.
