Abstract
There are many different kinds of ontologies used for different purposes in modern computing. Lightweight ontologies are easy to create, but difficult to deploy; formal ontolgies are relatively easy to deploy, but difficult to create. This paper presents an approach that combines the strengths and avoids the weaknesses of lightweight and formal ontologies. In this approach, the ontology includes only high level concepts; subtle differences in the interpretation of the concepts are captured as context descriptions outside the ontology. The resulting ontology is simple, thus it is easy to create. The context descriptions facilitate data conversion composition, which leads to a scalable solution to semantic interoperability among disparate data sources and contexts.
