Social navigation for the spoken web

This paper describes our experiences deploying a recommender system for a mobile phone-based knowledge sharing application to farmers in rural India. Users of the system record questions and call back for answers left by other users and experts. We used collaborative filtering to derive relevant content for each user based on historical navigation patterns of the community. An empirical analysis of behavioral and interview data reveals key issues for future mobile recommender systems in developing regions of the world. Copyright 2010 ACM.
