Embodiment 1

[0108] The method of the present invention is used to automatically generate a timeline summary of the event "Nth Room", and the results are as follows:

[0109] date Sub-event summary (substitute title for longer summary content) 2020-03-23 Dr. Zhao's identity in Room N is revealed 2020-04-09 Hundreds of thousands of people in South Korea petition to replace the judge in "Room N" 2020-04-17 The 18-year-old accomplice of South Korea's "Nth Room" was shown to the public 2020-04-29 South Korea's "House N" principal appears in court for the first time 2020-05-18 The founder of Room N was publicly revealed 2020-06-05 The founder of South Korea's "Nth Room" was detained by the prosecutor and charged

Abstract

The invention discloses a method for automatically generating timeline abstracts based on event detection technology, comprising: S10, clustering news text collections to obtain sub-event document collections of news events, each sub-event document collection corresponding to a sub-event; S20, obtaining A summary of each sub-event document set; S30, screen the sub-events, automatically determine the timeline summary length L', and the corresponding L' sub-events; S40, obtain the sub-event document sets corresponding to the L' sub-events , sort the abstracts in order of date, and output a sequence of abstracts with timestamps. And, automatic generation of timeline summaries based on event detection techniques, electronic devices and storage media. The invention has the advantages of being able to automatically determine the length of the timeline abstract, strong flexibility, and being able to deal with dynamically changing news events.

Description

technical field [0001] The present invention relates to the field of natural language processing. More specifically, the present invention relates to a method for automatically generating timeline summaries based on event detection technology. Background technique [0002] The automatic generation of news event timeline summaries is to identify key dates or sub-events from a large number of news documents with a long time span, and generate a short description for each date or sub-event, construct a collection of summaries with timestamps, and finally form Timeline summary. The automatic generation of timeline summaries not only reduces labor costs, but also improves users' reading efficiency. [0003] A high-quality timeline summary requires the system to be able to select a set of dates or sub-events that can cover the key content of the event (that is, the length of the timeline). In the existing scenario, the timeline summary generation adopts two strategies: setting ...
