Abstract

The invention belongs to the technical field of computers, and particularly relates to a named entity recognition method and device, equipment and a storage medium, which are used for improving the named entity recognition efficiency. The named entity recognition method comprises the steps of obtaining a target text to be subjected to named entity recognition, and obtaining a word embedding vector sequence corresponding to the target text; the word embedding vector sequence is input into a named entity recognition model, the output of the obtained named entity recognition model is a target category label sequence corresponding to a named entity in a target text, and the named entity recognition model is used for extracting target feature vectors corresponding to word embedding vectors contained in the word embedding vector sequence in parallel; classifying the target feature vectors in parallel; and obtaining a named entity recognition result of the target text according to the target category label sequence. The named entity recognition efficiency can be greatly improved.

Description

technical field [0001] The present application belongs to the field of computer technology, and in particular relates to a named entity recognition method, device, equipment and storage medium. Background technique [0002] Natural language processing technology can better realize the interaction between human and computer, among which named entity recognition is an important part of natural language processing technology. Named entity recognition refers to the process of identifying the names or symbols of things with specific meanings in the text. Named entities mainly include person names, place names, institution names, dates, proper nouns, etc. If the named entities in the text can be identified more accurately, it will help the computer to better understand the semantics of the language and perform tasks better, thereby improving the human-computer interaction experience. [0003] At present, the commonly used named entity recognition scheme is: input the target text ...
