Abstract

The invention embodiment discloses a method and device generating a multi-file summary, so the generated multi-file summary can have high coverage rate for multi-file important information, and redundancy can be reduced; the method comprises the following steps: destructing a multi-file sentence set into a phrase pool, and obtaining feathers and relations of each phrase in the phrase pool; selecting a phrase set, satisfying a preset constraint condition, from the phrase pool as a summary phrase set according to the features and relations; combining the selected summary phrase set into summary sentences according to a preset combination mode, thus forming the multi-file summary.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method and device for generating multi-document summaries. Background technique [0002] In the era of information explosion, people are increasingly in urgent need of rapid and effective information processing methods in the face of massive amounts of information. 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 takes multiple documents under the same topic as input, and automatically generates a specific length summary text for users to read. Thereby improving the efficiency of information reading and information acquisition. [0003] At present, sentences from multiple documents can be clustered, and then the dependency tree / dependency graph dependency graph can be used to fuse cla...
