Ontology-Extended Component-Based Workflows: A Framework for Constructing Complex Workflows from Semantically Heterogeneous Software Components

摘要

Virtually all areas of human endeavor involve workflows -that is, coordinated execution of multiple tasks. In practice, this requires the assembly of complex workflows from semantically heterogeneous components. In this paper, we develop ontology-extended workflow components and semantically consistent methods for assembling such components into complex ontology-extended component-based workflows. The result is a sound theoretical framework for assembly of semantically well-formed workflows from semantically heterogeneous components.
