The task of automatically detecting emotion in text is challenging. This is due to the fact that most of the times, textual expressions of affect are not direct - using emotion words - but result from the interpretation and assessment of the meaning of the concepts and their interaction, described in the chains of actions presented. This article presents the core of EmotiNet, a knowledge base (KB) for representing and storing affective reaction to real-life contexts and action chains described in text, and the methodology employed in designing, populating, extending and evaluating it. The basis of the design process is given by a set of self-reported affective situations in the International Survey on Emotion Antecedents and Reactions corpus. From the evaluation performed, we conclude that our final model represents a semantic resource appropriate for capturing and storing the semantics of real actions and predict the emotional responses triggered by chains of actions.
