Using navigation spectra for internet media sites classification

Recommendation systems play an important role in the modern Internet, providing users with the information they need. The development of recommendation systems requires both an understanding of user behaviour and continuous improvement in the quality of the information provided. In this paper we demonstrate how the use of the method of navigation spectra can significantly improve the quality of media sites classification. We describe how the application of this method allows us to build whitelists of media sites for more than a hundred countries. These lists are later used in the real recommendation system.
