I am trying to build a Recommendation system that could use the information from facebook. Well on the process I am trying to find the similarity between a user and his friends. That way I could consider only n similar friends information as a training data set, instead of all the friends. So I would appreciate some suggestions regarding the features from facebook which could be used as measure of similarity. One such feature would be, say age. Friends within same age group would be similar.
