Design and Implementation of Web English Teaching Information Retrieval Platform Based on Page Link Mining

Abstract

How to effectively use the huge information base of web for English teaching information retrieval plays an important role in English teaching reform. The traditional keyword based search engine has made some achievements, but there is a problem of low precision. In fact, the link structure between web pages implicitly expresses authoritative information, which has been used by many researchers to improve the performance of Web Information Retrieval (including search engines). This method has achieved good results, but there is still a lot of room for improvement. Therefore, this paper proposes a Web graph authority resource mining algorithm based on frequency. This method interprets the new definition of authority page, and proposes the concepts of frequent subgraph with order and authoritative community. Experimental results show that the algorithm improves the effectiveness of information retrieval.
