Method and device for generating multi-document summarization

Abstract

The embodiment of the invention discloses a method and a device for generating a multi-document summarization, relates to the field of data processing and solves the problem of poor performance of a summarization generated by an existing automatic multi-document summarization technology. A specific scheme of the method comprises the steps of dividing multiple documents into n sentences; generatingan input word bag vector; performing unsupervised training on each sentence represented by the input word bag vector to obtain an encoding hidden layer vector of each sentence and a potential semantic vector of each sentence; collecting m potential semantic vectors; obtaining m decoding hidden layer vectors and m output word bag vectors according to the m potential semantic vectors; updating them decoding hidden layer vectors and the m output word bag vectors; estimating an importance degree of each sentence; acquiring the importance degree and a redundancy degree of a verb phrase of each sentence and the importance degree and the redundancy degree of a noun phrase of each sentence; and generating the summarization of multiple documents according to the importance degree and the redundancy degree of all noun phrases and the importance degree and the redundancy degree of all verb phrases. The embodiment of the invention is used for a process for generating the multi-document summarization.

Description

technical field [0001] The embodiments of the present application relate to the field of data processing, and in particular to a method and device for generating multi-document summaries. Background technique [0002] In the era of information explosion, facing massive amounts of information, people are increasingly in urgent need of rapid and effective means of information processing. As one of the channels for obtaining information, news reading occupies a considerable part of people's life. However, the mass and redundancy of news brings great inconvenience to people's reading. Multi-Document Summarization (MDS) technology refers to the automatic generation of short summaries with a word limit for multiple documents on a topic, which can describe the main content of the topic to the maximum extent for users to read. Thereby improving the efficiency of information reading and information acquisition. [0003] From the summary generation method, it can be divided into th...
