The contextual analysis can help to determine the specific meaning of the polysemy in a sentence and rule out the ambiguities 利用上下文语境可以确定多义词在语句中的具体语义、排除歧义，可以确定语句中词语的语法意义。
A simple analysis on the differences among conversion words and homophones , polysemants and flexible uses of words are made so as to confirm judge - standard of conversion words 通过兼类词与同音词、多义词、词的活用等语言现象之间区别的浅析，便可以初步确定兼类词的判定标准。
Polysemy is realized on the basis of image schema by the means of metaphor and metonymy , and it expands from the basic meaning to the extended meanings , with those extended meanings having close relations with each other 一词多义现象是在一定的意象图式的基础上，借助隐喻和转喻模式实现的，是由基本词义向其它词义的引申，而且多义词各义项之间相互关联。
Lsa is similar to vector space mode ( vsm ) , representing textual materials with space vectors . lsa can advance the accuracy of subsequent processes by using a truncated singular value decomposition ( svd ) to remove the influences of synonymy 在技术上,它同向量空间模型类型类似,都是采用空间向量表示文本,但通过svd分解等处理,消除了同义词、多义词的影响,提高了后续处理的精度。
Now , the most word sense disambiguation algorithm on the parallel corpora is limited in the context of the single ambiguous word and its alignment information . in this paper , we made full use of computability of the concept in the hownet and changed word sense disambiguation problem into the similarity calculation problem between the ambiguous word and the whole sentence of the other language . in this way , we disambiguated the ambiguous word from a new point of view and achieved the satisfactory result 当前大多数基于双语语料的词义排歧算法都局限在利用单个多义词的上下文环境及其对应信息，本文则充分利用当前hownet资源中概念的可计算性，将词义排歧的问题转化为多义词和另一种语言的相应句子的整体意义相似性问题，从一个新的角度来进行词义排歧，因此得出了满意的研究结果。
With the help of grammatical context , we can make students understand that the same word used in the different grammatical structures may have different meaning , certain words can be only occurred in a particular grammatical context , and differem parts of speech may have different functions in the sentence . in other words , in grammatical context , the syntactic structure of the context determines various individual meaning of a polysemous word . with the help of lexical context , students can study the collocative relationship and the collocative meaning of the word 借助语法语境，可以让学生理解同一词语在不同的句法结构中的意义是不尽相同的，某些词只能出现在特定的句法结构中，以及不同的词类出现在句中有着不同的功用等；词汇语境可以帮助学生理解和把握词的搭配关系，当和不同的词搭配在一起的时候，词语的意义可能发生变化，某些词只能和特定的词搭配在一起使用；言语语境不仅能帮助学生理解词的意义，而且还可以使学生懂得如何利用言语环境的帮助来猜测和确定生词的意义，使多义词在特定的语境中的含义得以定位。
