Introducing Docear's Research Paper Recommender System. In their early stage, recommender systems only focused on pure information filtering field. In section 7.4 we explain MAP: Mean Average Precision. The authors then introduced a number of "item re-ranking methods that can generate substantially more diverse recommendations across all users while maintaining comparable levels of recommendation accuracy. Today we introduce UnSuggester, “the worst recommendation system ever devised™.” UnSuggester is a brand new idea in recommender technology. In this demo paper we present Docear's research paper recommender system. Following the post on evaluation metrics in your blog, we would be glad to help you testing new evaluation metrics for GraphChi. Until recently, this literature suggests, research on recommendation systems has focused almost exclusively on accuracy, which led to systems that were likely to recommend only popular items, and hence suffered from a "popularity bias'' (Celma and Herrera 2008). Title: An MDP-based Recommender System MDPs introduce two benefits: they take into account the long-term effects of each recommendation, and they take into account the expected value of each recommendation. Not long ago (this year, actually), with Sherry we wrote a book Chapter on recommender systems focusing on sources of knowledge and evaluation metrics.
