Kurzfassung
The technical challenges associated with the development and
deployment of ontologies have been subject to a considerable
number of research initiatives since the beginning of the
nineties. The economical aspects of these processes are, however,
still poorly exploited, impeding the dissemination of
ontology-driven technologies beyond the boundaries of the academic
community. This paper aims at contributing to the alleviation of
this situation by proposing ONTOCOM (ONTOlogy
COst Model), a model to predict the costs
arising in ontology engineering processes. We introduce a
methodology to generate a cost model adapted to a particular
ontology development strategy, and an inventory of cost drivers
which influence the amount of effort invested in activities
performed during an ontology life cycle. We further present the
results of the model validation procedure, which covered an
expert-driven evaluation and a statistical calibration on
36 data points collected from real-world
projects. The validation revealed that ontology engineering
processes have a high learning rate, indicating that the building
of very large ontologies is feasible from an economic point of
view. Moreover, the complexity of ontology evaluation, domain
analysis and conceptualization activities proved to have a major
impact on the final ontology engineering process duration.
