观点摘要的www会议论文，摘要如下： This paper presents a new unsupervised approach to gen- erating ultra-concise summaries of opinions. We formulate the problem of generating such a micropinion summary as an optimization problem, where we seek a set of concise and non-redundant phrases that are readable and represent key opinions in text. We measure representativeness based on a modied mutual information function and model readability with an n-gram language model. We propose some heuris- tic algorithms to eciently solve this optimization problem. Evaluation results show that our unsupervised approach out- performs other state of the art summarization methods and the generated summaries are informative and readable.
