Structural quantization of vagueness in linguistic expert opinions in an evaluation programme

This paper aims to develop a methodology for the construction of a membership function for linguistic expert opinions in a realistic evaluation problem. It contains a PC-aided procedure of information acquisitions and modelling of data for favour of an evaluator's aid. It assumes that the evaluator need not be knowledgeable in fuzzy mathematics but use common linguistic terms in the making of his expert comments and uses his subjectivity and common reasoning ability (and sincerity) in conversation with the system. For this purpose, a follow-up model is supplemented which assumes existence of a single expert only.
