An algorithm of word indexing model for document summarization based on perspective of document

Computer Engineering

Natural language processing (NLP) is an area of computer science, artificial intelligence, and computational linguistics connected with the communications between computers and natural languages. There are many challenges in NLP involve natural language understanding, that is, enabling computers to derive meaning from human or natural language input, and others involve natural language generation. Document summarization is a part of it. Many different classes of such process based on machine learning are developed. In researches earlier document summarization mostly use the similarity between sentences in the document to extract the most significant sentences. The documents as well as the sentences are indexed using traditional term indexing measures, which do not take the context into consideration. The resulting indexing weights are used to compute the sentence similarity matrix. The proposed sentence similarity measure has been used with the baseline graph-based ranking models for sentence extraction.
