Actions are productive concepts, but they are both linguistically and cognitively underdetermined: what defines an action in the event continuum is still an open question. The linguistic encoding of actions offers both problems and solutions to the issue of identifying these concepts. First of all, many action verbs do not identify one single action, but can refer to different action concepts. Secondly, each language categorizes actions in its own way. The IMAGACT Ontology of Action adopts a flexible approach of categorization that allows to deal with different levels of action concepts in different language. To this aim, IMAGACT exploited the systematic annotation of Local Equivalence relations, which correspond to the possibility that different verbs (with different meanings) refer to the same action concept. However, the observation of Local Equivalence cannot solve the problem of action identification by itself: it has to be associated with the evaluation of the productivity of the relation. When productivity is missing, the local equivalence is not essential and exists just for an accidental pragmatic fact.
