TITLE:
Collaborative filtering: prospects and problems

ABSTRACT:
Today's abundance of information and of consumer choice in a variety of
domains is making recommendation systems increasingly important in 
helping users find the items they are interested in. Such recommendation 
systems are often based on the idea of collaborative filtering, 
effectively utilizing the correlations among ratings explicitly or 
implicitly provided by users of the system, and are already in 
widespread use in recommending books, movies, songs, etc. I'll consider
the prospects of this technology and in particular discuss some open 
problems that need to be solved for such systems to realize their full
potential. In addition, I will focus on the possibilities and obstacles 
when applying such techniques to the scientific research literature. 


Welcome!
