Towards Building a Competitive Opinion Summarization System: Challenges and Keys
نویسندگان
چکیده
This paper presents an overview of our participation in the TAC 2008 Opinion Pilot Summarization task, as well as the proposed and evaluated post-competition improvements. We first describe our opinion summarization system and the results obtained. Further on, we identify the system’s weak points and suggest several improvements, focused both on information content, as well as linguistic and readability aspects. We obtain encouraging results, especially as far as Fmeasure is concerned, outperforming the competition results by approximately 80%.

متن کاملThe Pareto Principle Is Everywhere: Finding Informative Sentences for Opinion Summarization Through Leader Detection
Most previous works on opinion summarization focus on summarizing sentiment polarity distribution towards different aspects of an entity (e.g., battery life and screen of a mobile phone). However, users’ demand may be more beyond this kind of opinion summarization.
