AI Technical Summary

Technical Problem

The prior art is difficult to effectively solve the long-tail word meaning disambiguation task under low resources, especially when the number of training samples is insufficient and the word meaning annotation text is limited.

Method used

Using a method based on the constraints of a class of quantum non-homologous representation, the traditional and quantum word meaning recognition scores are calculated by obtaining the target word representation and word meaning definition representation, and adding them as the final word meaning disambiguation result, to improve the accuracy of word meaning definition representation and distinguish boundaries.

Benefits of technology

It significantly improves the accuracy of long-tail word meaning recognition under low resources and can be applied to text representation problems under other low resources, verifying the effectiveness of this method in the long-tail word meaning disambiguation task.

Abstract

The invention discloses a word sense disambiguation method based on quasi-quantum non-homologous representation constraint. The method comprises the following steps: obtaining target word representation corresponding to a target word in a to-be-disambiguated text; obtaining word meaning definition representation and word meaning example representation in the dictionary; based on the target word representation and the word meaning definition representation, respectively calculating similarity scores of the target word representation and each word meaning representation, namely traditional word meaning recognition scores; calculating a similarity score of the target word representation and the word meaning representation obtained under each non-homologous representation constraint mechanism, namely a quantum word meaning recognition score; and adding the results of the traditional word meaning recognition score and the quantum word meaning recognition score to serve as a word meaning recognition result finally output by the word meaning disambiguation model.
