Keyword Based User Profiling for News Recommendation
News Recommendation is increasingly being deployed by online news publishers. Recommender Systems are
used as a way to deal with information overload and to increase page views. Collaborative filtering and content based
filtering are two common approaches used in recommendation systems. In this paper, we propose a News Recommendation
System Model that uses keywords obtained from the articles to profile the user. We then use a collaborative filtering model
to generate recommendations to the users. Coping with ever changing user interests is also a major challenge for
recommendation system. This model also proposes a decay function to deal with such a challenge.
