Fuzzy usability evaluation of Information systems in Public administration

摘要

This paper deals with the problem of evaluating a usability of information systems in public administration based on a theory of fuzzy sets. For such purpose, a completely new methodology has been created. The evaluation of the model is based on a set of criteria that synthesizes commonly used Web usability guidelines. Together with the model, Fuzzy Usability Evaluator - the application that is able to operate with the vague nature of evaluating has been developed. While the inputs are fuzzy measures, the output of the model is a crisp value representing an overall usability score of the Web portals in Public administration.
