In this paper a new technique is presented for automatic design of optimal questionnaires. The technique, that is based on the Item Response Theory, performs multiple-choice item selection by a Genetic Algorithm. The experimental results demonstrate the validity of the proposed approach to adjust the characteristics of the questionnaire to the abilities of the student class.

Having a modern application capable to automatically collect and process data from users, based on information and lifestyle answers is one of current challenges for researchers and medical science. The purpose of the current study is to integrate user experience design (UXD) in a cloud-based medical application to improve patient safety, quality of care and organizational efficiency. The proce...

In the era of data science, it is common to encounter with different subsets variables obtained for cases. An example split questionnaire design (SQD), which adopted reduce respondent fatigue and improve response rates by assigning sampled respondents.
