Abstract
Ontology Engineering is currently advancing from a pure research topic to real
applications. This state of the art is emphasized by the wide range of European
projects with major industry involvement and, in the same time, by the
ever-growing interest of small and medium size enterprizes asking for
consultancy in this domain. A core requirement in all of these efforts is,
however, the availability of proved and tested methods which allow an efficient
engineering of high-quality ontologies, be that by reuse, new building or
automatic extraction methods. Several elaborated methodologies, which aid the
development of ontologies for particular application requirements, emerged in
the last decades. Nevertheless, in order for ontologies to be built and deployed
at a large scale, beyond the boundaries of the academic community, one needs not
only technologies and tools to assist the engineering process, but also means to
estimate and control its overall costs. These issues are addressed only
marginally by current engineering approaches though their importance is well
recognized in the community. Different approaches exist to estimate costs for
engineering processes. We will present the parametric cost estimation model ONTOCOM. Part of parametric cost estimation model is the identification of
relevant cost drivers and the alignment of the cost factors with a process model.
Therefore we identify the cost drivers relevant for the five process steps in
the DILIGENT model. Based on the cost function some analytical evaluations of
application scenarios for the DILIGENT model are provided.
