Topic modeling for answers detection in online game chats

Sirotkin A., Musabirov I., Okopny P., Bulygin D., Ivanov V.

Helping behavior is a significant part of social learning process in online games. One type of such a behavior is answering questions in a chat. We provide a method to detect if the question asked in a chat was answered and by whom. Proposed method is based on topic modeling for chat messages and comparison of a detected topic of question with a topic of possible reply. We show its efficiency on chat messages from online games.
