Embodiment Construction

[0022] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0023] figure 1 It is an application environment diagram of the named entity recognition method in one embodiment. refer to figure 1 , the named entity recognition method is applied to the named entity recognition system. The named entity system includes a terminal 110 and a server 120 . Terminal 110 and server 120 are connected via a network. The terminal 110 runs a service processing platform, such as a search platform or a payment platform, and users operate (such as search or pay) on the service processing platform of the terminal to generate service text data. Th...

Abstract

The present application relates to a named entity recognition method, device, computer-readable storage medium and computer equipment. The method includes: obtaining the regular expression corresponding to the frequent sequence text pattern of the current business scene, and combining the text to be extracted with the regular expression Perform pattern matching, extract corresponding text information from the text to be extracted according to the matched regular expression, and obtain a named entity extraction result of the text to be extracted. This method automatically mines entity recognition patterns based on the frequent sequence pattern mining algorithm, extracts recognition rules from limited patterns to obtain frequent sequence text patterns, and converts them into regular expressions for extraction without parameter adjustment, which saves parameter adjustment time and further improves improved the efficiency of named entity recognition.

Description

technical field [0001] The present application relates to the technical field of natural language processing, in particular to a named entity recognition method, device, computer-readable storage medium and computer equipment. Background technique [0002] Named Entity Recognition (NER), also known as "proper name recognition", refers to identifying entities with specific meanings in texts, mainly including names of people, places, institutions, names of works, network words with specific meanings, etc. Proper nouns, etc., as well as text such as time, quantity, currency, and proportional values. Named entity recognition has a wide range of application scenarios in practical applications, such as the entity name of the point of interest, the determination of the entity in the search, the determination of the payment subject in the payment, etc. [0003] Named entity recognition has been widely used in various fields, and the current methods for named entity recognition are ...
