Text key information extraction method and device, electronic equipment and storage medium

Abstract

The invention discloses a text key information extraction method and device, electronic equipment and a storage medium, and relates to the field of artificial intelligence. According to the specific implementation scheme, an original text is segmented according to preset segmentation units, and a unit sequence corresponding to the original text is generated; extracting recognition information of at least one target fragment based on the original text by adopting a fragment copying principle according to the unit sequence and a pre-trained information extraction model; and generating key information based on the recognition information of the at least one target segment. According to the technical scheme, the segment comprising the continuous words can serve as the target segment to be copied, in the process of extracting the key information, the frequency of copying can be effectively reduced, accumulated errors are reduced, and then the speed and accuracy of extracting the key information can be effectively improved.

Description

technical field [0001] The present application relates to computer technology, especially to the field of artificial intelligence technology, and in particular to a method, device, electronic equipment and storage medium for extracting key information of text. Background technique [0002] Key information extraction in text, that is, copying key information fragments from text and splicing them into key information, has been widely used in many natural language processing tasks. For example, in the task of automatically extracting abstracts from text, key information can be copied from the text as an abstract or title. Another example, in the information extraction task, accurately copy entities and texts that reflect the relationship between entities to achieve extraction. Therefore, improving the accuracy of copying key information fragments can improve the performance of upper-layer application tasks, thereby serving the final product. [0003] In existing key informati...

Problems solved by technology

[0004] However, the word-level copying scheme in the above-mentioned existing key information extraction process needs to be continuously copied multiple times when continuously copying segments including multiple words, which will accumulate errors and cause the accuracy of the key information extraction of the text to be relatively low.
