Abstract

The embodiment of the invention relates to artificial intelligence, and provides a Chinese named entity recognition method and device, a storage medium and electronic equipment, and the method comprises the steps: obtaining a to-be-recognized Chinese text sequence; for each character in the Chinese text sequence, determining a relative position code of a current character and each character in the Chinese text sequence; determining a query matrix and a measurement matrix corresponding to the Chinese text sequence based on the type of the named entity type; and for each named entity category, according to the query matrix, the measurement matrix and each relative position code, judging whether the character segments from the position i to the position j in the Chinese text sequence belong to the current named entity category or not. According to the scheme provided by the embodiment of the invention, the problem of error propagation caused by sequence labeling is solved, and accurate named entity category identification can be carried out on any text fragment in the Chinese text sequence.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of artificial intelligence, and in particular to a Chinese named entity recognition method, device, storage medium and electronic equipment. Background technique [0002] Chinese named entity recognition (Named Entity Recognition, NER) is a deep learning technical method for extracting specified information in articles. It is common to extract information such as automobile brands, auto parts, parts quality, and quotations. NER technology is a very important basic task in Natural Language Processing (NLP), and is the basic task for building knowledge graphs, information search and other application tasks. The general Chinese NER method is to carry out the task in the form of sequence labeling, and add a prefix to each word in the text according to BIOE, for example: B-BRAND indicates the initial text of the brand category, I-BRAND indicates the middle text of the brand category, E-B...
