Compressive Document Summarization via Sparse Optimization

  title={Compressive Document Summarization via Sparse Optimization},
  author={Jin-ge Yao and Xiaojun Wan and Jianguo Xiao},
In this paper, we formulate a sparse optimization framework for extractive document summarization. The proposed framework has a decomposable convex objective function. We derive an efficient ADMM algorithm to solve it. To encourage diversity in the summaries, we explicitly introduce an additional sentence dissimilarity term in the optimization framework. We achieve significant improvement over previous related work under similar data reconstruction framework. We then generalize our formulation… CONTINUE READING
