Evolving multimedia ontologies: the BSM tool environment

Goal of this paper is to present the BOEMIE Semantic Manager (BSM) tool environment providing advanced tool-assisted functionalities for domain experts and content managers to support design and evolution of ontology knowledge about multimedia resources. In particular, key features of the tool are i) the capability to figure out the different situations where available background knowledge is not sufficient for multimedia resource interpretation, and ii) the capability to support the design of the missing knowledge not only through the traditional "from scratch" approach, but also by enforcing the (re)use of externally harvested matching knowledge chunks.
