A New Lexical Chain Algorithm Used for Automatic Summarization
نویسندگان
چکیده
Lexical chains are widely used as a representation of text for Natural Language Processing tasks. However, efficient algorithms for the construction of lexical chains often resort to local decisions. We propose a new algorithm for Lexical Chaining, based on a global function optimization through Relaxation Labelling. A preliminary evaluation of the performance of our approach has been performed on a Catalan agency news corpus. The comparison to an efficient state-ofthe-art algorithm for Lexical Chaining gives promising results. The resulting lexical chainer has been used for a complete multilingual Automatic Summarization system, available on-line.

Biogeography-Based Optimization Algorithm for Automatic Extractive Text Summarization
Given the increasing number of documents, sites, online sources, and the users’ desire to quickly access information, automatic textual summarization has caught the attention of many researchers in this field. Researchers have presented different methods for text summarization as well as a useful summary of those texts including relevant document sentences. This study select...
متن کاملLexical Cohesion Based Topic Modeling for Summarization
In this paper, we attack the problem of forming extracts for text summarization. Forming extracts involves selecting the most representative and significant sentences from the text. Our method takes advantage of the lexical cohesion structure in the text in order to evaluate significance of sentences. Lexical chains have been used in summarization research to analyze the lexical cohesion struct...
متن کاملExtractive Based Automatic Text Summarization
Automatic text summarization is the process of reducing the text content and retaining the important points of the document. Generally, there are two approaches for automatic text summarization: Extractive and Abstractive. The process of extractive based text summarization can be divided into two phases: pre-processing and processing. In this paper, we discuss some of the extractive based text ...

While automatic text summarization is an area that has received a great deal of attention in recent research, the problem of efficiency in this task has not been frequently addressed. When considering the size and quantity of documents available on the Internet and from other sources, the need for a highly efficient tool that produces usable summaries is clear. We present a linear time algorith...
متن کاملUsing Genetic Algorithms with Lexical Chains for Automatic Text Summarization
Automatic text summarization takes an input text and extracts the most important content in the text. Determining the importance of information depends on several factors. In this paper, we combine two different approaches that have been used in the text summarization domain. The first one is using genetic algorithms to learn the patterns in the documents that lead to the summaries. The other o...
