Abstract

In recent years, aspect-level sentiment analysis has been widely used in product evaluation, catering, e-commerce decision-making, etc. A core point of this task is aspect word extraction. At present, the commonly used method is to use opinion words to assist in extracting aspect words to mark the text sequence, or to use span notation to predict the beginning and ending positions of aspect words. These methods do not consider the influence of opinion word extraction and emotion polarity classification on aspect word extraction. Aiming at this problem, this paper proposed a multi-relationship collaborative learning model for aspect extraction, which used opinion word extraction, aspect word extraction, and relationship modeling between emotion polarity classification to achieve multi-task collaborative learning and joint training in relationships. The experimental results on the three datasets of REST14, REST15 and LAP14 show that the proposed method is better than the current state-of-the-art method.
