情报学中概念的组配性质,概念之间联系的多维性以及它们的整体所显示的某种线性空间的性质,是矩阵与向量运用到情报学中的前提。检索系统矩阵向量模型对传统的情报检索理论和方法是一次带有根本性质的变革,其潜力是不可忽视的。一、概念及概念空间概念是反映客观事物的一般的、本质的特征,概念词是这种特征的文字表述。概念之间的联系是空间的多维的,任何一个复杂概念可以由简单概念组合而成。我们如果把每个简单概念用一根座标轴表示,那么任何
The nature of the composition of concepts in informatics, the multidimensional relations among concepts, and the properties of some linear space displayed by them as a whole are the prerequisites for using matrices and vectors in informatics. The retrieval system matrix vector model is a fundamental change to the traditional information retrieval theory and method, whose potential can not be neglected. First, the concept and concept of space Concept is to reflect the general nature of the objective things, the concept of words is the character of the text. The connection between concepts is multi-dimensional in space. Any one complex concept can be composed of simple concepts. If we put each simple concept with a coordinate axis, then any
