Opinosis Opinion & Text Summarization Library

The Opinosis Summarizer Software is a text summarizer that generates concise abstractive summaries of highly redundant text. It  was primarily used to summarize opinions, and thus it can  be regarded as a opinion summarization software.

Abstract

This paper presents a new unsupervised approach to generating 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 modifi ed mutual information function and model readability with an n-gram language model. We propose some heuristic algorithms to efficiently solve this optimization problem.
