A ective computing studies and develops both systems and de- vices to recognize, interpret, process, and simulate human a ect| i.e., the experience of feelings or emotions. Software engineering involves people in a broad range of activities (from requirements to validation) where personality, moods, and emotions play a crucial role. Recently, researchers have started to study the role of af- fective computing and a ective states in software engineering but contributions on this topic are presented and discussed in diverse conferences and workshops. The SEmotion workshop follows on the fourth edition held at ICSE 2019, towards the consolidation of an international, sustainable forum for researchers and practition- ers interested in the role of a ects in software engineering to meet, present, and discuss their work-in-progress. SEmotion showcases contributions about empirical methods for emotions detection in software engineering, theoretical models inspired by neighboring elds, as well as ad-hoc tools for supporting emotion awareness in software development. This paper presents and overview of the fth edition of the workshop.
