Conceptual Modeling of Geographic Information System Applications [chapter]

Adnan Yazici, Kemal Akkaya

Weighting of Features in Content-Based Filtering with Entropy and Dependence Measures

Jorge Castro, Rosa M. Rodriguez, Manuel J. Barranco
2013 International Journal of Computational Intelligence Systems  
In this contribution, it is proposed a new method for obtaining the weights of the features by means of entropy and coefficients of dependency.  ...  In such a process, it is very interesting to know which features of the items are more important for each user, thus the CBRS provides them higher weight.  ...  Before applying these measures, it is necessary to fix a relevance criteria to decide whether a product is relevant for a user.  ...

Rocchio Algorithm to Enhance Semantically Collaborative Filtering [chapter]

Sonia Ben Ticha, Azim Roussanaly, Anne Boyer, Khaled Bsaïes
2015 Lecture Notes in Business Information Processing  
The aim of our approach is to predict users preferences for items based on their inferred preferences for semantic information of items.  ...  Recommender system provides relevant items to users from huge catalogue. Collaborative filtering and content-based filtering are the most widely used techniques in personalized recommender systems.  ...  For example, the attribute movie genre is multivalued because a movie can have several genres while movie origin is a mono valued attribute because a movie has only one origin.  ...
