Collecting Information for Action Understanding: The Enrichment of the IMAGACT Ontology of Action

This paper presents the status of our work aimed at enriching the IMAGACT Ontology of Action by linking it to other resources. In order to achieve this goal we performed a visual mapping, exploiting the IMAGACT visual component (video scenes that represent physical actions) as the linkage point among resources. By using visual objects, which are free from linguistic constraints and can be interpreted and described from different perspectives, we connected resources responding to different scopes and theoretical frameworks, in which a concept-to-concept mapping appeared difficult to obtain. We provide a brief description of two linking obtained by using this technique: an automatic linking between IMAGACT and BabelNet, a multilingual semantic network, and a manual linking between IMAGACT and Praxicon, a conceptual knowledge base of action.
