Abstract

The invention provides a named entity identification and linking method and device, equipment and a readable storage medium. The method comprises the steps of obtaining a to-be-recognized text containing a special name; based on a pre-constructed dictionary, performing word segmentation on the to-be-identified text, and obtaining a target entity word corresponding to the special name; and determining the type of the target entity word based on the annotation information of the target entity word, wherein the dictionary comprises entity words and background words, the probability of the entitywords is nonlinearly related to the length of the entity words, the probability of the background words is nonlinearly related to the length of the background words, and both the probability of the entity words and the probability of the background words are used for word segmentation of the to-be-recognized text. The method can improve the accuracy of named entity identification.

Description

technical field [0001] The present disclosure relates to the technical field of computer applications, and in particular to a method, device, device and readable storage medium for identifying and linking named entities. Background technique [0002] With the development of semantic recognition technology, the application of named entity recognition and linking technology has been widely used. For example, a voice assistant in a smart device (smartphone, tablet, etc.) obtains the user's voice, converts the voice into text through voice recognition, and needs to identify the named entities in it, and then link the identified named entities to corresponding knowledge base. For example, if the user voice inputs "play Qilixiang", after the smart device recognizes the song "Qilixiang", it will use music skills to link it to the playback software to play the song. [0003] However, the current named entity and link technology is still difficult to disambiguate. [0004] It shou...
