As stated in the previous chapters, recommender systems have long been a favorite application area for agent and multiagent systems researchers. The recommender systems space has traditionally been divided into systems that try to analyse the contents of documents and system that use methods other than content analysis. Content-based filtering systems are using techniques like weighed keyword vectors and SVD, while collaborative filtering and pair-wise ratings are used in the second systems category. In this chapter we will introduce two systems: Amalthaea, that falls in the former category and uses weighed keyword vectors as its representation and Histos, a pair-wise rating system that falls in the latter category.
