Abstract

A synonym search method and device, said method comprising: inputting into an optimized word vector matrix a component word to be matched, said optimized word vector matrix being obtained using pre-set models, said pre-set models including a Word2vec model used for obtaining the component word and a Skip-Gram model trained using said component word as a training sample, said component word to be matched being a component word in a pre-set word library (S101); obtaining from the optimized word vector matrix a target word vector corresponding to the component word to be matched; calculating separately the cosine distances between the target word vector and other vectors in the optimized word vector matrix (S102); obtaining n synonyms of the component word to be matched according to all cosine distances and the pre-set word library (S103). Said device implements the method, and enhances the accuracy of synonym search.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of word processing, and in particular to a method and device for searching synonyms. Background technique [0002] Synonym lookup is an important research topic. The existing synonym lookup method analyzes the number of times each word appears in the current text and the number of times it appears in the entire text collection, and then uses the word frequency information to model the text as a vector, and then uses the one-hot-encoding encoding algorithm Or algorithms such as tf-idf, and use the cosine similarity between vectors, jaccard similarity and other methods to calculate the similarity between words, that is, the existing technology is based on the similarity method of word frequency information to search for synonyms. [0003] However, when studying the semantics of words, it is actually necessary to figure out how people use a certain word when describing objective thing...
