为了解决评价分析中同时具有可比性和不可比性的语言值问题,采用格蕴涵代数的方法去处理语言值。基于十元语言值格蕴涵代数,建立了一个新的语言值教学评价系统模型。该方法能够很好地表达和处理评价问题中的可比信息和不可比信息,且具有丰富的适用于语言值推理的蕴涵运算。在评价分析过程中语言值直接参与推理和运算。研究结果表明所提出的方法在教学评价系统对处理语言值推理时更有效。该成果将有助于推动智能评价系统的实现。
To solve the evaluation problems such as both comparable and incomparable linguistic values exist at the same time,it is proposed that the linguistic values are processed using lattice implication algebra. Based on 10-element linguistic-valued lattice implication algebra,a new model for linguistic-valued teaching evaluation system is built. The proposed approach can better express and process both comparable and incomparable information. With its implication characteristics,it can better perform the linguistic-valued reasoning in evaluation process. The reasoning and operations are directly acted by the evaluation linguistic values. The study result shows that the proposed approach is very efficient for linguistic-valued teaching evaluation under a fuzzy environment with both comparable and incomparable linguistic values. It is very useful for achieving an intelligent evaluation system.
