The category identification unit 710 may implement topic modeling based on Latent Dirichlet Allocation (LDA) for identification of a viewing category and a sub-category. Topic modeling is a method of analyzing words existing in various documents and applying them to statistical models to analyze the subject of each document. There are several approaches to performing topic modeling, and the present disclosure uses one of them, LDA. The graph 900 applies LDA-based topic modeling to content related to sports, news, and entertainment viewed by a user.

LDA, a kind of topic modeling, is a Probabilistic Model using Bayesian inference, and considers documents as a mixed model of subjects, and assumes that these subjects are composed of probability distributions of words. In other words, assuming that a person writes a subject when writing, and assuming that he or she writes by probabilistically selecting the subject and the words related to the subject, conversely, a large number of document groups are used to construct words. The subject can be inferred, and the similarity calculation and classification work between documents can be efficiently and accurately performed. In the inference process, a modified Expectation-Maximization algorithm or Markov Chain Monte Carlo Gibbs Sampling is used. When this is applied to vectorized data such as text, images, and user behavior patterns, it is possible to infer the topics related to the data.

LDA is a stochastic generation model that generates a group of documents. It is assumed that documents are represented by topics, which are randomly generated randomly mixed models, and each topic is modeled to be composed of probability distributions of words. Because the generation model goes through three levels of hierarchical Bayesian inference, the topic is represented by the Dirichlet distribution, a special conjugate dictionary probability characteristic. Therefore, the previously complicated calculation process can be simplified by using the Dirichlet distribution known in advance.
