| Abstract: | Focusing Service is one of the main solutions to solve the personal accurate service of the internet information resource. This paper presents an approach of information resource focusing service based on subject analysis. It proposed a TF-IDF-IM algorithm, which combining the user interest and document classify technologies, and then constructed a subject-tree and a subjects-relation-graph, which can realize the accurate information focusing service effectively. |
