Autoabstract method for multi-document

Abstract

The invention discloses a method which utilizes a graph partition method to automatically extract a multi-document summarization, and the method comprises the following steps that: the sentence boundary dividing is carried out, and the document is expressed by the divided sentences; the sentences are expressed into vectors, the similarities among each two sentences are calculated to compose a sentence incidence matrix, which is reduced according to the appointed threshold value, at the same time, the normalized treatment is carried out; the crawling of the implied logical topic of a topic is introduced into the multi-document summarization, and a document set is divided into different implied sub-topics according to the topic, thereby the summarization task is changed into the selection and the extraction processes to the sub-topics; by applying the graph partition method, the importance degree of the sub-topic of the sentences is ensured from the global characteristics, and the low redundancy of the contents among the different sub-tops is ensured from the local characteristics, thereby effectively improving the quality of the summarization.

Description

technical field [0001] The present invention relates to the field of information processing, and further relates to a multi-document automatic summarization method. Background technique [0002] With the progress of the times and the development of the economy, people's demand for information in daily life is increasing, especially with the increasing popularity of the Internet, a large amount of information is released and disseminated on the Internet every day.
