现代情报检索模型理论比较与发展研究

Research on the Comparison and Development of Modern Information RetrievalModel Theories

关于相关性的计量一直是情报检索的核心问题 ,为此 ,人们提出了一系列检索模型。本文从比较与发展的角度 ,按时间顺序介绍了布尔模型、向量空间模型、概率模型、模糊模型、逻辑模型、概念模型、网络模型等 ,并在分析、比较与评价的基础上 ,对情报检索模型研究发展的未来趋势做了一些预测。

The measure for relativity is key to information retrieval, so a series of information retrieval model (IRM) are put forward to answer it in theory and practice. In this article, Boolean logic model (BLM), vector model of information retrieval (VRM), probabilistic model of information retrieval (PRM), fuzzy information retrieval model (FRM), logical model, concept based IRM and net model are discussed in chronological sequence from the point of comparison and development. At the end this article attempt to describe the future development trends of IRM on the basis of analysis, comparison and evaluation of the above-mentioned models.
