Quality assessment of cultural web sites with fuzzy operators

We present FQT4Web, a quantitative inspector-based methodology for Web site evaluation, with a hierarchical structure. A new approach, based on fuzzy operators, permits a sophisticated aggregation of measured atomic quality values, using linguistic criteria to express human experts' evaluations. A wide reference to standards and the limited number of subjective items increase the reliability of site analysis. This methodology has been fine-tuned for cultural sites; however, the assessment method is general-purpose. It is possible to obtain quality charts, which allow decision-makers to validate site quality on the basis of design goals
