Evaluating Option-related Text Descriptions for Decision Aiding

This short paper presents an approach for evaluating the meaning of text descriptions regarding the appropriateness of a method, a tool, or, in general, of an approach, for solving ill-structured, ill-defined problems. This evaluation approach is based on the framework of fuzzy sets and in particular, test score semantics [9]. The text descriptions are descriptions of problems which correspond to a number of (sub)problems belonging to human activity systems elicited and represented through the use of soft systems methodology (SSM)[1,2,6]. A number of papers [3,4] have described the overall approach through specific problem spaces. An implemented decision support system to support computer system designers in the area of human computer interaction, which was based on the above approach is also described in a previous paper. The specific theme of this paper is to present and discuss some further aspects of the reasoning of such a system.
