Practical Experiences in Trading Off Ontology Usability and Reusability
Abstract
This paper describes the practical application of ontologies in
designing knowledge-based systems. We built a common ontology to allow
knowledge sharing among several applications in the domain of air
campaign planning. In trying to reuse this shared ontology, we confirmed
previous findings in the knowledge acquisition literature: it is
difficult to simultaneously obtain high usability (i.e., adequacy for a
specific use) and reusability (i.e., adequacy for several uses). In this
article, we discuss some of the reasons for this trade-off, and present
some lessons learned about the limitations of current tools for ontology
construction in practical applications.
