Method Research Of The E-learning Resources Collecting And Automatic Classification Based On Focused Crawling Technique

With the explosive growth of Internet, the E-learning resources is more and more abundant, and with the rapid development of information technology education, establishment of structural E-learning resources become more and more valued. A rich and well-structured E-learning Resources can not only effectively improve the quality of teaching, promoting educational reform, but also to meet the needs of modern education.However, there are some problems for the current construction of the E-learning Resources: the resource is not rich, organizational chaos and so on, the rapid development of information technology offers the possibility to solve these problems, study how to use existing information technology serve as the establishment of structural E-learning resources is become a very important issue.Based on analyzes the current status of the E-learning Resources construction and presentation of related information technology, A set of method use of existing information technology serve as the establishment of structural E-learning resources is proposed and research the first two parts of the method for the first two parts: First, for the focused crawler is to collected the specific topic information online, the ACO is proposed to guide its search strategy——ACO-FC, proved by experiment the validity of the proposed method, it's provide a guarantee for access to rich learning resources online. Secondly, for the collection E-learning resources, analysis by the PSO and K-means, an improved hybrid clustering algorithm——ISPO + K-means, and compared with several other algorithms, the experimental results show that the new clustering algorithm is better, so able to capture down to automatically organize learning resources, reduce manual labor and improve efficiency.This paper aims to find a set of method use of existing information technology serve as the establishment of structural E-learning resources, hope for the establishment of structural E-learning resources provide some useful reference.
