In this work we describe a novel approach to goal-oriented knowledge capturing that, differently from the standard knowledge acquisition pipelines, employs a dynamic conceptual reframing mechanismrelying on a non monotonic reasoning procedure. This approachhas been implemented in a knowledge based system able to findthe solution to not directly satisfiable goals by recombining, in aninnovative way, at least two concepts of a given knowledge base(KB). The output of such combinatorial mechanism results, de facto, in an extension of the initial KB able to satisfy the original goal. The proposed approach has been tested in the task of goal-driven concept invention and has been compared with human responses.
