Abstract

The invention discloses a named entity recognition method, a named entity recognition device, equipment and a medium. The named entity recognition method comprises the following steps: acquiring a voice signal in a specific scenario; extracting a voice feature vector in the voice signal; extracting a character feature vector in a character result according to the character result subjected to voice recognition based on the voice signal; splicing the voice feature vector and the character feature vector so as to obtain a composite feature vector of each character in the voice signal; and processing the composite feature vector of each character in the voice signal by virtue of a deep learning model, thereby obtaining the named entity recognition result.

Description

technical field [0001] The present disclosure relates to the field of artificial intelligence, and more specifically relates to a named entity recognition method, a named entity recognition device, a named entity recognition device and a medium. Background technique [0002] With the development of artificial intelligence and big data technology, the technical requirements for speech recognition and natural language processing continue to increase. Among them, named entity recognition, as a necessary pre-operation for tasks such as semantic understanding and speech synthesis, plays an important role in natural language understanding. effect. [0003] At present, the commonly used entity recognition methods are mostly aimed at speech recognition in a wide range of application scenarios. However, in special scenarios, such as works of art with complex special names, books, foreign names, etc., existing named entity recognition methods are difficult to recognize well. [0004]...
