Abstract

Background User Experience (UX) evaluation is crucial for Information Systems, as it is closely related to their acceptance and post-adoption performance. It often involves the use of one or more standardized questionnaires. This evaluation can
be costly, from selecting the appropriate questionnaire to extracting data from a significant number of users, analyzing the data and comparing results, especially with evaluations that use different questionnaires. Thus, Artificial Intelligence is increasingly adopted to aid these tasks. To this end, we explore several machine learning (ML) algorithms to correlate and predict the answers of different UX and mood questionnaires. Results The developed approach successfully predicted
questionnaire responses with high accuracy (error less than 1 on a 7-point Likert scale), particularly for the longer
questionnaire. Additionally, it revealed that mood significantly contributes to this accuracy. Conclusions Our main
contributions include demonstrating how ML can be utilized to reduce UX evaluation costs and exploring the impact of user mood on this evaluation.
