摘要	The information dissemination model is becoming increasingly important in wide-area information systems. In this model, a user subscribes to an information dissemination service by submitting profiles that describe his interests. There have been several simple kinds of information dissemination services on the Internet such as mailing list, but the problem is that it provides a crude granularity of interest matching. A user whose information need does not exactly match certain lists will either receive too many irrelevant or too few relevant messages. 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's interests modeling and information recommendation. A Concept Network is constructed upon the user's profiles and the content of documents,, which describes concepts and their relations in the content and assigns different weights to these concepts. Usually the Concept Network is not well arranged, from which it is hard to find some useful relations, so several views from are extracted it to represent the important relations explicitly.
