Application: Method and apparatus for named entity recognition, and non-transitory computer-readable recording medium (Patent ID: US20230394240A1)

The patent filed by Ricoh Co Ltd. describes a method and apparatus for named entity recognition, involving traversing text elements in a text to identify candidate entity words and recognizing the class to which each candidate entity word belongs. This recognition process includes generating a prompt template, concatenating the text with the template to create a concatenated text, generating vector representations of the text elements, and classifying the candidate entity word based on these representations. The method also involves integration processes to obtain span representations of the candidate entity word and the use of a mask word for classification.

Furthermore, the apparatus described in the patent includes memory storing computer-executable instructions and processors to execute these instructions. The apparatus is designed to traverse text elements, recognize the class of candidate entity words, generate prompt templates, concatenate text, and perform integration processes to classify the candidate entity words. The apparatus utilizes vector representations and a softmax function to determine the probability of candidate entity words belonging to different classes, ultimately selecting the class with the highest probability. Overall, the method and apparatus aim to improve named entity recognition by utilizing prompt learning, vector representations, and integration processes for accurate classification.
