The topic of my presentation is an approach to the problem of automated identification of Internet users’ interests. The core of the proposed approach is the technique called Latent Dirichlet Allocation — a Machine Learning method based on an elegant probabilistic generative model. After minor adjustments the model appears to be applicable to the problem of user interests identification. We will discuss the algorithm used to train the model and sketch its MapReduce implementation. To demonstrate the efficiency of the proposed approach I will present the results of modeling Mail.Ru Group users’ interests. The presentation is intended for technical specialists interested in applying Machine Learning methods to Big Data processing.
