Similarity Based Collaborative Filtering Model for Movie Recommendation Systems

摘要

Recommendation systems are information filtering tools and techniques which provide valuable suggestions to users about items they may like by considering various attributes. In Recommendation algorithms, similarity metrics are the main components and performances of these will have direct influence on the recommendations generated. Selecting suitable Similarity measures will be a major factor in improving performance of data mining techniques.
