A Study on Mapping Users' Topic Interest for Question Routing for Community-based Q&A Service

본 연구에서는 커뮤니티 기반 질의응답 서비스에서의 질의할당을 위하여, 해당 커뮤니티에 축적된 질의응답 데이터 세트를 이용하여 해당 카테고리내의 토픽을 분석하고 이를 바탕으로 해당 토픽에 관심을 가지는 이용자의 관심 토픽을 분석하고자 하였다. 특정 카테고리 내의 토픽을 분석하기 위해서 LDA기법을 사용하였고 이를 이용하여 이용자의 관심 토픽을 모델링하였다. 나아가, 커뮤니티에 새롭게 유입되는 질의에 대한 토픽을 분석한 후, 이를 바탕으로 해당 토픽에 대해 관심을 가지고 있는 이용자를 추천하기 위한 일련의 방법들을 실험하였다.

Abstract

The main goal of this study is to investigate how to route a question to some relevant users who have interest in the topic of the question based on users’ topic interest. In order to assess users’ topic interest, archived question-answer pairs in the community were used to identify latent topics in the chosen categories using LDA. Then, these topic models were used to identify users’ topic interest. Furthermore, the topics of newly submitted questions were analyzed using the topic models in order to recommend relevant answerers to the question. This study introduces the process of topic modeling to investigate relevant users based on their topic interest.
