HCI and Natural Progression of Context-Related Questions.

The ability of humans to effectively interact socially relies heavily on their awareness of the context the interaction takes place. In order for computer systems to accordingly possess the same ability, it is crucial they are also context-aware in terms of a formalization of context based on the W5+ framework aspects ofWho, What, Why, Where, What and How. Research work presented in this paper contributes towards this goal by bridging the conceptual gap and exploiting semantics and cognitive and affective information of non verbal behavior and investigating whether and how this information could be incorporated in automatic analysis of affective behavior. A semantic concept extraction methodology is proposed and its application to indicative examples from the SEMAINE corpus is presented that validates the proposed approach.
