Advanced web-based systems are needed for creating an infrastructure e-supply chain. However, this requires more than the technical connectivity of entities or the sharing of online data. What is required is a semantic system that embeds human expertise and knowledge in a computer-understandable format. Therefore, ontologies are needed as a foundation for such semantic systems. Since no single ontology will be universally utilized, dynamic ontology merging presents itself as a solution to facilitate interoperability among several organizations using different process models and ontologies. This research proposes an ontology that benchmarks a sample of models. It also introduces formal concept analysis as an approach for merging different ontologies.
