Abstract

The embodiment of the invention provides a named entity recognition method and device, a named entity recognition method and device for an e-commerce platform, a case clue recognition method and device, a content recognition method and device, electronic equipment and a computer storage medium. The named entity recognition method comprises the steps of generating a basic graph corresponding to a to-be-recognized text, wherein the basic graph comprises a plurality of character nodes; obtaining a word matching rule matched with the to-be-recognized text, wherein the word matching rule comprises a plurality of words and a word order relationship among the words; determining a plurality of first character nodes corresponding to the words in the word matching rule from a plurality of character nodes of the basic graph; according to the word order relation between words in the word matching rule, at least adding a connecting edge used for representing the word matching rule into the basic graph, generating a target graph to recognize the named entity in the to-be-recognized text, and connecting the connecting edge used for representing the word matching rule with part or all of the first character nodes.

Description

technical field [0001] The technical field of data processing in the embodiment of the present application, in particular, relates to a named entity recognition method and device, a named entity recognition method and device for an e-commerce platform, a case clue recognition method, a device, a content recognition method, a device, an electronic device, and computer storage media. Background technique [0002] Named Entity Recognition (NER for short), also known as "proper name recognition", refers to the automatic identification of entities with specific meanings in texts through automated methods, mainly including names of people, places, institutions, trade names, proper nouns etc. Named entity recognition plays an important role in the field of text processing, such as question answering systems, translation, etc. [0003] However, some words can be understood as different meanings in different situations, that is, they need to be identified as different entities. For...
