Sergey Koltsov and Olesya Koltsova told the participants of the Summer School about the method of topic modeling: the features of approaches in topic modeling (TM) with a focus on regularization models based on Gibbs-sampling, the problem of stability of the TM and the problem of choosing the number of topics in TM were considered. The participants also had an opportunity to get acquainted with the professional soft "TopicMiner" developed at the laboratory for Internet studies, and practiced in its use in solving practical problems, e.g., the profiling of users of social networks and predicting their attributes.
The conference was held from 2 to 4 September where Olessia Koltsova took part as a keynote speaker. Her report "Topic modeling of user-generated content: opportunities and limitations" was devoted to considering the possibilities and limitations of topic models, especially LDA models.
