User Profile Model: A View from Artificial Intelligence

The goal of this paper is to develop a user profile model for agent-based information filtering. We try to formalize the whole process of information filtering from an Artificial Intelligence point view. This research is related to develop novel techniques for interactive information gathering with the application of Artificial Intelligence, and Information Retrieval technologies. In this paper, we present a dynamical model to represent user profiles. We describe the user profiles as random sets on a concept space (taxonomy). We also present a rough set based qualitative decision model for the task of information filtering.
