term weight 基本例句 词汇权重 In local retrieval,the newterm weightcalculation method is designed to solve the problem about txt search in homogeneous collection.对于本地检索设计了新的词条权重的计算方法,解决了同构文档集内的文本检索问题。 The new method establishes vector space model ofterm weightaccording to the theory of latent semantic index, and may eliminate disadvantageous factors.该方法应用lsi理论来建立文本集的向量空间模型;在词条的权重中引入了语义关系;消减了原词条矩阵中包含的“噪声”因素;从而更加突出了词和文本之间的语义关系. The key technologies are studied and the improvedterm weightalgorithm of VSM is put forward.Then the paper sets out the platform’s function model, and its design and development.介绍平台的框架结构,对其关键技术进行研究,提出一种向量空间模型特征词权重的改进算法,然后阐述平台的功能模型和各模块的设计与开发。 |
