Dual-mode-based event corpus automatic construction method and device and storage medium

Abstract

The embodiment of the invention relates to the field of data processing, and discloses a dual-mode-based event corpus automatic construction method and device and a storage medium. The dual-mode-basedevent corpus automatic construction method includes: acquiring the first subject event keyword inputted by a user; retrieving a first topic event corpus according to a first topic event keyword, andexpanding the first topic event corpus to obtain a second topic event corpus; obtaining the third topic event corpus according to the correlation between the second topic event corpus and the topic, and forming the corpus by the third topic event corpus. Through the dual-mode-based event corpus automatic construction method, experts are not required to annotate news information related to the subject event, thus improving the efficiency of constructing the corpus and saving the labor cost. Moreover, a corpus of all relevant events can be automatically collected, so the corpus is made to be more complete and accurate.

Description

technical field [0001] The embodiments of the present invention relate to the field of data processing, and in particular to a method, device and storage medium for automatically constructing an event corpus based on dual modes. Background technique [0002] In recent years, network technology has developed rapidly, and Internet data has become the main source of information for people due to its advantages such as rapid update, wide range, and easy access. According to statistics, the vast majority of network data are stored in the form of text, recording a large number of news events, and these news events often revolve around a certain theme. In the era of big data, all news events related to a certain topic are screened out from massive data, and a corpus of news topic events is constructed, which is helpful for the mining and analysis of news events. [0003] The inventors found that there are at least the following problems in the prior art: when constructing most new...

Problems solved by technology

[0003] The inventors found that there are at least the following problems in the prior art: when constructing most news topic event corpora, experts often need to manually label news information related to topic events, which is not only inefficient but also high in cost

And for news events, generally a theme event will have many related sub-theme events, it is difficult to collect all relevant event corpus during manual labeling, resulting in incomplete corpus, incomplete coverage, and low accuracy
