Core entity labeling method and device and electronic equipment

Abstract

The invention provides a core entity labeling method and device and electronic equipment, and relates to the technical field of intelligent search. The method comprises the following steps: respectively carrying out character vector mapping, word vector mapping and entity vector mapping on a target text to obtain a character vector sequence, a first word vector sequence and an entity vector sequence respectively corresponding to the target text; generating a target vector sequence corresponding to the target text according to the character vector sequence, the first word vector sequence and the entity vector sequence corresponding to the target text; encoding and decoding the target vector sequence by using a preset network model, and determining a start character probability and an end character probability of taking each character in the target text as a core entity; and determining the core entity of the target text according to the start character probability and the end characterprobability of each character as the core entity. Therefore, through the core entity labeling method, the core entity in the text is accurately extracted, the semantic information of the core contentof the text is enriched, and the universality is good.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of intelligent search technology, and proposes a core entity labeling method, device and electronic equipment. Background technique [0002] With the development of information technology, text data is growing explosively. In the face of massive text content, it is impossible to extract the core content only by manual processing. Therefore, computer technology is urgently needed to realize intelligent understanding of text content and realize automation. , Intelligent text content production, processing and distribution recommendations. Among them, entity understanding is an important part of text understanding, and other fine-grained text understanding results such as corresponding entity profiles and topics can be extended through the annotation of core entities, which can help users better understand webpage text resources or according to The user's inte...

AI Technical Summary

Problems solved by technology

[0004] The core entity labeling method, device and electronic equipment proposed by this application are used to solve the problem of characterizing the core content of short texts by extracting keywords of short texts in related technologies. Since keywords are not necessarily entity words, the determined Short text core content, lack of semantic information, difficult to meet different application requirements
