Abstract

The embodiment of the invention provides a named entity recognition method and device, equipment and a machine readable medium. The method comprises: segmenting a to-be-recognized text into a plurality of language units; calculating the distance between any two adjacent language units in the plurality of language units; according to the distance between any two adjacent language units, combining the plurality of language units to obtain one or more combined language units; and determining an entity recognition result corresponding to the to-be-recognized text according to the entity information corresponding to the one or more combined language units. According to the embodiment of the invention, the named entity recognition efficiency can be improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a named entity recognition method, a named entity recognition device, a device, and a machine-readable medium. Background technique [0002] With the popularity of computers and the rapid development of the Internet, a large amount of information appears in the form of electronic documents. In order to cope with the severe challenges brought by the information explosion, automated tools are needed to extract truly valuable information from massive amounts of data, and information extraction came into being. Named entities refer to entities with specific meanings in the text, such as names of people, places, institutions, proper nouns, etc. Named Entity Recognition (NER, Named Entity Recognition) Named Entity Recognition plays an important role in information extraction. It can accurately identify and classify proper nouns representing named entities in te...
