Challenges and solutions in the opinion summarization of user-generated content

Estimating mass opinion from subjective texts on the Web can beuseful for many real-world applications e.g., marketing, business intelligence,product assessment, decision-support etc. In this paper, we present di erentapproaches to summarizing opinion. We apply these approaches to: a) identifypositive and negative opinions in blog threads in order to produce a list ofarguments in favor and against a given topic and b) summarize the opinionexpressed in reviews. Subsequently, we evaluate the proposed methods on twodistinct datasets and analyze the quality of the obtained results, as well asdiscuss the errors produced. Finally, we conclude that the proposed approachis appropriate in the context of opinion summarization.
