摘 要: | 基于X结构的词义选择利用单词所在的X结构,并与词典的用法部分的X结构相比较,通过比较结构及结构中其它词的相似性来决定单词的含义,单词间的相似性利用WordNet来实现.这一方法只要较少的学习例子,可以避免传统的基于单词同现的方法中需要大量的语料库及数据稀少等问题。

A WORD SENSE DISAMBIGUATION BASED ON X-BAR |
| |
Abstract: | A word sense disambiguation based on X bar is introduced. The approach compares the word's X bar with the usage in the dictionary from two aspects:the structure and the words in the X bar. The words' similarity is evaluated using WordNet. The approach has the virtue of the demand for a small training set and it can avoid the problems in traditional methods based on word co occurrence, such as the demand for a large corpus, sparse data, etc . |
