A New Approach to Managing the Evolution of OWL Ontologies

摘要

The growing demand for large and complex on-tologies present new challenges related to their design, maintenance and evolution. In this paper, we propose an approach to managing the evolution of large OWL on-tologies. Unlike conventional approaches that focus on the versioning of entire ontology, we use an evolutionary log to track the lifeline of each axiom or annotation that appears in an evolving ontology. We introduce the formal model for our ontology evolution framework, present related algorithms, and discuss the potential implementation scenarios.
