Using a Double Clustering Approach to Build Extractive Multi-document Summaries
نویسندگان
چکیده
This paper presents a method for extractive multi-document summarization that explores a two-phase clustering approach. First, sentences are clustered by similarity, and one sentence per cluster is selected, to reduce redundancy. Then, in order to group them according to topics, those sentences are clustered considering the collection of keywords that represent the topics in the set of texts. Evaluation reveals that the approach pursued produces highly informative summaries, containing many relevant data and no repeated information.

SIMBA: An Extractive Multi-document Summarization System for Portuguese
This is a proposal for demonstration of simba in PROPOR 2012. simba is an extractive multi-document summarization system that aims at producing generic summaries guided by a compression rate defined by the user. It uses a double-clustering approach to find the relevant information in a set of texts. In addition, simba uses a sentence simplification procedure as a mean to ensure summary compress...

متن کاملUsing N-Grams To Understand the Nature of Summaries
Although single-document summarization is a well-studied task, the nature of multidocument summarization is only beginning to be studied in detail. While close attention has been paid to what technologies are necessary when moving from single to multi-document summarization, the properties of humanwritten multi-document summaries have not been quantified. In this paper, we empirically character...
متن کاملA Hybrid Approach to Multi-document Summarization of Opinions in Reviews
We present a hybrid method to generate summaries of product and services reviews by combining natural language generation and salient sentence selection techniques. Our system, STARLET-H, receives as input textual reviews with associated rated topics, and produces as output a natural language document summarizing the opinions expressed in the reviews. STARLET-H operates as a hybrid abstractive/...
متن کاملFeature expansion for query-focused supervised sentence ranking
We present a supervised sentence ranking approach for use in extractive summarization. Using a general machine learning technique provides great flexibility for incorporating varied new features, which we demonstrate. The system proves quite effective at query-focused multi-document summarization, both for single summaries and for series of update summaries.
