A Framework for Generating Extractive Summary from Multiple Malayalam Documents

Abstract

Automatic extractive text summarization retrieves a subset of data that represents most notable sentences in the entire document. In the era of digital explosion, which is mostly unstructured textual data, there is a demand for users to understand the huge amount of text in a short time; this demands the need for an automatic text summarizer. From summaries, the users get the idea of the entire content of the document and can decide whether to read the entire document or not. This work mainly focuses on generating a summary from multiple news documents. In this case, the summary helps to reduce the redundant news from the different newspapers. A multi-document summary is more challenging than a single-document summary since it has to solve the problem of overlapping information among sentences from different documents. Extractive text summarization yields the sensitive part of the document by neglecting the irrelevant and redundant sentences. In this paper, we propose a framework for extracting a summary from multiple documents in the Malayalam Language. Also, since the multi-document summarization data set is sparse, methods based on deep learning are difficult to apply. The proposed work discusses the performance of existing standard algorithms in multi-document summarization of the Malayalam Language. We propose a sentence extraction algorithm that selects the top ranked sentences with maximum diversity. The system is found to perform well in terms of precision, recall, and F-measure on multiple input documents.

Extractive approach for text summarisation using graphs

“…Average document-summary compression 0.85 (8) implements the TextRank algorithm and expands on the pre and post-processing part. The data (sentences) is encoded and different methods are considered such as tf-idf and Word2vec.…”

A boundary-based tokenization technique for extractive text summarization

“…In a recent study by Manju et al [16] extractive text summarization technique was adopted to make sense of the sensitive part of the document by neglecting the irrelevant and redundant sentences. The researchers proposed a framework for extracting summary from multiple documents in the Malayalam Language by a sentence extraction algorithm that selects the top ranked sentences which also has maximum diversities.…”

“…They have provided acceptable accuracy with a shorter computational time. Recently, machine learning and deep learning have progressed rapidly and resulted in significant achievements in several fields, such as natural language processing [16], computer vision [17], and recommendation systems [18]. Since deep neural networks can effectively learn complex data representation, studies regarding neural networks can be applied to construct complex relationships among users and services.…”
