Summary

This is the second chapter about aspect-based sentiment analysis. In Section 2.1.1, we defined each opinion as a quintuple (e, a, s, h, t), where e is an entity and a is one of its aspects, s is the sentiment about the aspect a, h is the opinion holder, and t is the time when the opinion is expressed. Chapter 5 focused on aspect-based sentiment classification, which determines s. This chapter addresses extraction of entities and aspects about which sentiments or opinions have been expressed.
