Chinese word sense disambiguation based on neural networks

摘要

The input of a network is the key problem for Chinese word sense disambiguation utilizing the neural network.This paper presents an input model of the neural network that calculates the mutual information between contextual words and the ambiguous word by using statistical methodology and taking the contextual words of a certain number beside the ambiguous word according to( - M,+ N).The experiment adopts triple-layer BP Neural Network model and proves how the size of a training set and the value of M and N affect the performance of the Neural Network Model.The experimental objects are six pseudowords owning three word-senses constructed according to certain principles.The tested accuracy of our approach on a closed-corpus reaches 90.31% ,and 89.62% on an open-corpus.The experiment proves that the Neural Network Model has a good performance on Word Sense Disambiguation.
