Questionnaires are widely used instruments for usability evaluation, but their correct construction is often a complex task since several previous administrations are required to obtain a fine-tuned version of the questionnaire. In this work, we describe a novel approach to design questionnaires that is based on a knowledge representation of the concepts involved in questionnaire-based usability evaluation. As a proof of concept of the model, a prototype has also been constructed, aimed at supplying a guided questionnaire development process especially useful for novel Web designers.
