■Title
A Joint Model of Term Extraction and Polarity Classification for Aspect-based Sentiment Analysis

■Abstract
Aspect-based sentiment analysis (ABSA) is a significant task in opinion mining, which aims to extract explicit aspects of an entity along with the sentiment expressed towards these aspects. To achieve this goal, two subtasks are performed: aspect term extraction (ATE) and aspect polarity classification (APC). However, recent work has solved these two subtasks separately. In this paper, we propose a joint model for ABSA that can deal with two subtasks, ATE and APC, simultaneously. The experimental results show that the performance of our proposed method is better than or comparable to previous methods. This paper presents the study of the first author's master thesis.

■Comment
It is extremely grateful and honor to receive the Best Paper Award at KSE 2018 conference.
First, I would like to express the deepest appreciation to my supervisor, Associate Professor Kiyoaki Shirai who was always willing to give me the advice on the problem that I was stuck. Without his guidance, I might not finish the research on time and achieve this prize.
Moreover, I would like to thank Associate Professor Minh Le Nguyen, Associate Professor Shinobu Hasegawa, and Associate Professor Kokoro Ikeda for their useful comments in mid-term and final-term defenses that were key points in improving the quality of my paper in term of content and presentation.
Finally, special thanks to my family, all members of Shirai's and Hasegawa's laboratories, and my friends. They not only gave me the encouragement and inspiration but also was beside me whenever I was in trouble.
