网站自动评价中的指标形式化研究

Study on Formalizing Indicators in Automated Website Evaluation

对评价指标形式化进行界定,分析指标形式化的原理,重点探讨指标形式化所涉及的两个关键问题,为指标的形式化提供有效途径。提出一种多层次、二维的指标映射模型,该量化模型实现从网站评价目标到度量的转换;设计一种简单的指标映射模型定义语言IMMDL,实现指标的形式化表示。

This paper gives the definition of the formalization and analyzes the principles. Two key problems are discussed. It provides the effective approach of the formalization. The author proposes an indicator mapping model, which is multi - level and two -dimension. This quantitative model realizes the transform of evaluation goals and metrics. The author also designs the indicators mapping model definition language, which is used for formalized description of indicators.
