User Modeling and User-Adapted Interaction
| Hi-index | 0.00 |
Adaptive surveys provide an efficient method for customizing questionnaires to the particular requirements of a study and specific features of the respondent. Hypermedia can enhance the presentation of questionnaires and enables interactive feedback. As comparability of survey results is crucial, adaptation is constrained by the requirement of cognitive equivalence. The scenario of a survey-based early warning system for virtual enterprises supplies a context for the discussion of further requirements concerning structure, markup, and adaptation of surveys. An XML markup for adaptive surveys is proposed that is applied within a survey system for virtual enterprises.
