Automatic Text summarization (ATS) is a viable option to reduce the content of textual documents, e.g., as a possible preprocessing step in many text mining applications. single-document extractive summarizers have been developed based on different approaches, but many of them have the drawback of producing summaries with low coherence among the selected sentences in the generated summaries. In this paper, we present an unsupervised summarization system as an attempt towards coherent extractive single-document summarization. This system relies on Integer Linear Programming (ILP) as an optimization technique for selecting the smallest subset of sentences of a document maximizing the coverage of relevant concepts. Furthermore, our solution uses a graph-based algorithm for two goals: representing both sentences and concepts and enabling local coherence scoring among the sentences in the generated summaries. The proposed system is evaluated on two single-document benchmark datasets (DUC 2001-2002) using ROUGE measures, and compared with other state-of-the-art summarizers. The achieved results are very competitive.

Automatic single-document summarization is a process that receives a single input document and outputs a condensed version with only the most relevant information. This paper proposes an unsupervised concept-based approach for single-document summarization using Integer Linear Programming (ILP). Such an approach maximizes the coverage of the important concepts in the summary, avoiding redundancy, and taking into consideration some readability aspects of the generated summary as well. A new weighting method that combines both coverage and position of the sentences is proposed to estimate the importance of a concept. Moreover, a weighted distribution strategy that prioritizes sentences at the beginning of the document if they have relevant concepts is investigated. The readability of the generated summaries is improved by the inclusion of constraints into the ILP model to avoid dangling coreferences and breaks in the normal discourse flow of the document. Experimental results on the DUC 2001-2002 and the CNN corpora demonstrated that the proposed approach is competitive with state-of-the-art summarizers evaluated regarding the traditional ROUGE scores.

single-document summarization is a challenging task. In this paper, we explore effective ways using the tweets linking to news for generating extractive summary of each document. We reveal the very basic value of tweets that can be utilized by regarding every tweet as a vote for candidate sentences. Base on such finding, we resort to unsupervised summarization models by leveraging the linking tweets to master the ranking of candidate extracts via random walk on a heterogeneous graph. The advantage is that we can use the linking tweets to opportunistically "supervise" the summarization with no need of reference summaries. Furthermore, we analyze the influence of the volume and latency of tweets on the quality of output summaries since tweets come after news release. Compared to truly supervised summarizer unaware of tweets, our method achieves significantly better results with reasonably small tradeoff on latency;compared to the same using tweets as auxiliary features, our method is comparable while needing less tweets and much shorter time to achieve significant outperformance.

Due to the great amount of documents available on the Web, end users need to be able to access information in summary form - keeping the most important information in the document. The methods employed for automatic text summarization generally allocate a score to each sentence in the document, taking into account certain features. The most relevant sentences are then selected, according to the score obtained for each sentence. In this paper, the extractive single document summarization task is treated as a binary optimization problem and, based on the Global-best Harmony Search metaheuristic and a greedy local search procedure, a new algorithm called ESDS-GHS-GLO is proposed. This algorithm optimizes an objective function, which is a lineal normalized combination of the position of the sentence in the document, sentence length, and coverage of the selected sentences in the summary. The proposed method was compared with the state of the art methods MA-singleDocSum, DE, FEOM, UnifiedRank, Net-Sum, QCS, CRF, SVM, and Manifold Ranking, using ROUGE measures on the DUC2001 and DUC2002 datasets. The results showed that ESDS-GHS-GLO outperforms most of the state-of-the-art methods except MA-singleDocSum. ESDS-GHS-GLO obtains promissory results using a fitness function less complex than MA-singleDocSum, therefore requiring less execution time.

EXPERT SYSTEMS WITH APPLICATIONS 2016年 65卷 68-86页

作者： Oliveira, Hilario Ferreira, Rafael Lima, Rinaldo Lins, Rafael Dueire Freitas, Fred Riss, Marcelo Simske, Steven J. Univ Fed Pernambuco Recife PE Brazil Univ Fed Rural Pernambuco Recife PE Brazil HP Brazil Porto Alegre RS Brazil HP Labs Ft Collins CO 80528 USA

The volume of text data has been growing exponentially in the last years, mainly due to the Internet. Automatic Text summarization has emerged as an alternative to help users find relevant information in the content of one or more documents. This paper presents a comparative analysis of eighteen shallow sentence scoring techniques to compute the importance of a sentence in the context of extractive single and multi-document summarization. Several experiments were made to assess the performance of such techniques individually and applying different combination strategies. The most traditional benchmark on the news domain demonstrates the feasibility of combining such techniques, in most cases outperforming the results obtained by isolated techniques. Combinations that perform competitively with the state-of-the-art systems were found. (C) 2016 Elsevier Ltd. All rights reserved.

Preprocessing is a preliminary step in many fields including IR and NLP. The effect of basic preprocessing settings on English for text summarization is well-studied. However, there is no such effort found for the Urdu language (with the best of our knowledge). In this study, we analyze the effect of basic preprocessing settings for single-document text summarization for Urdu, on a benchmark corpus using various experiments. The analysis is performed using the state-of-the-art algorithms for extractive summarization and the effect of stopword removal, lemmatization, and stemming is analyzed. Results showed that these pre-processing settings improve the results.

Automatic document summarization has become increasingly important in the age of big data. However, traditional summarization systems have two major weaknesses: term-vector data sparsity and semantic information deficiency. In this paper, we solve these problems by adopting word and sentence embeddings, whose distributed nature enables the relation establishment between words and sentences. Experimental result shows that our models outperform two state-of-the-art graph based summarization systems.
