Hnatovskyj, Vítek ; Rozman, Jaroslav (referee) ; Zbořil, František (advisor)
This work focuses on a movie recommendation system. First, the issue of recommendation systems in general is described, and the various types of these systems are outlined. The main goal is to implement a system that recommends relevant movies to the user based on their preferences. This system is hybrid, consisting of a content-based system and a collaborative filtering system. To test the system, a simple application is implemented, which is also described in this work. Subsequently, the system is evaluated using offline metrics and user testing.

Recommendation system module analysis and design
KORTUS, Lukáš
Recommendation systems serve to users of e-commerce applications for individual recommendations to certain products or services based on their preferences. The aim of this thesis is to create a module of recommender system. The work includes analysis of recommendation systems and the methods used in these systems, including a description of the calculations. This work also solves the cold start problem, which is a problem when generation of some good recommendations for the new user is needed, but the recommendation system has no or little information about this user. Based on analysis is in this thesis designed module for recommender system, which is applicable e.g. internet for e-commerce or other internet-based application. Part of this module is the realization of a platform Apache Mahout, which some parts are built on a distributed computing platform Apache Hadoop project. Furthermore, in this work, on the aforementioned platform Mahout, selected methods of calculating the similarity using selected criteria (e.g. the average time for a recommendation, and the number of users for who have not been able to generate recommendations) are tested.
