Title:
SYNONYM DETERMINATION METHOD, COMPUTER-READABLE RECORDING MEDIUM IN WHICH SYNONYM DETERMINATION PROGRAM IS RECORDED, AND SYNONYM DETERMINATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/188883
Kind Code:
A1
Abstract:
A synonym determination method is provided with: a step of converting a word included in a document into a first vector which represents a meaning of the word; a step of acquiring a similarity between words on the basis of the first vector; a step of converting a sentence included in the document into a second vector which represents a meaning of the sentence; a step of acquiring a similarity between sentences on the basis of the second vector; a step of classifying the words included in the document on a topic basis; and a step of determining whether the words included in the document are a synonym or not on the basis of the similarity between the words, the similarity between the sentences, and the classification result on the topic basis. As a result, the present invention provides the synonym determination method by which a synonym determination can be automatically performed with high accuracy.
