Abstract

The invention discloses a named entity identification method and a device thereof, a computer readable storage medium and a processor. The method comprises the steps of obtaining text data; performing feature mapping on the text data to obtain a first text vector and a second text vector; and respectively inputting the first text vector and the second text vector into two channels of an identification model for named entity identification to obtain an identification result of the text data. According to the method and the device, the technical problem of relatively low identification performance caused by word embedding deviation easily occurring in a named entity identification process in related technologies is solved.

Description

technical field [0001] The present invention relates to the field of information extraction, in particular to a named entity recognition method and device, a computer-readable storage medium and a processor. Background technique [0002] With the increasing popularity of the Internet and the continuous development of computer technology, information extraction has received extensive attention. Information Extraction (IE) is mainly to structurally process unstructured information in the text, extract specific entities or events from the text, and help users automatically classify, extract, and reconstruct the content of massive texts. Named Entity Recognition (NER) is an important subtask of information extraction. Among them, Chinese named entity recognition refers to the computer identifying all named entities existing in a piece of Chinese text data according to their categories. [0003] In recent years, deep learning has been widely used in natural language processing t...
