A Personalized Information Dissemination System Based on How-Net

摘要

The information dissemination model is becoming increasingly important inwide-area information systems. In this model, a user subscribes to an information disseminationservice by submitting profiles that describe his interests. There have been several simple kindsof information dissemination services on the Internet such as mailing list, but the problemis that it provides a crude granularity of interest matching. A user whose information needdoes not exactly match certain lists will either receive too many irrelevant or too few relevantmessages. This paper presents a personalized information dissemination model based on How-Net, which uses a Concept Network-Views (CN-V) model to support information filtering, user'sinterests modeling and information recommendation. A Concept Network is constructed uponthe user's profiles and the content of documents, which describes concepts and their relationsin the content and assigns different weights to these concepts. Usually the Concept Network isnot well arranged, from which it is hard to find some useful relations, so several views from areextracted it to represent the important relations explicitly.
