Unsupervised query-focused multi-document summarization using the cross entropy method

Abstract

We present a novel unsupervised query-focused multi-document summarization approach. To this end, we generate a summary by extracting a subset of sentences using the Cross-Entropy (CE) Method. .Theproposed approach is generic and requires no domain knowledge. Using an evaluation over DUC 2005-2007 datasets with several other state-of-The-Art baseline methods, we demonstrate that, our approach is both effective and eficient.
