In paper, we propose an unsupervised text summarization model which generates a summary by extracting salient sentences in given document(s). In particular, we model text summarization as an integer linear programming problem. One of the advantages of this model is that it can directly discover key sentences in the given document(s) and cover the main content of the original document(s). This model also guarantees that in the summary can not be multiple sentences that convey the same information. The proposed model is quite general and can also be used for single- and multi-document summarization. We implemented our model on multi-document summarization task. Experimental results on DUC2005 and DUC2007 datasets showed that our proposed approach outperforms the baseline systems.
► We model unsupervised generic text summarization as an optimization problem.
► We define the objective function by weighted combination of the two objective functions based on the cosine and the NGD-based similarity measures.
► Experiments on DUC2005 and DUC2007 datasets show that the proposed model performs well.
