Business-OWL (BOWL)—A Hierarchical Task Network Ontology for Dynamic Business Process Decomposition and Formulation

Abstract

Collaborative Business Processes (cBPs) form the backbone of enterprise integration. With the growing reliance on the web as a medium of business collaboration, there is an increasing need to quickly and dynamically form cBPs. However, current Business-to-Business (B2B) information systems are still static in nature, and are unable to dynamically form cBPs based on high-level Business Goals (BGs)and their underlying criteria (e.g., item cost, product name, order quantity, etc). This paper introduces the Business-OWL (BOWL), an ontology rooted in the Web Ontology Language (OWL), and modeled as a Hierarchical Task Network (HTN) for the dynamic formation of business processes. An ontologized extension and augmentation of traditional HTN, BOWL describes business processes as a hierarchical ontology of decomposable business tasks encompassing all possible decomposition permutations. Through BOWL, high-level business goals (e.g., "Buy”) can be easily decomposed right down to the lowest level tasks (e.g., "Send Purchase Order”), effectively bridging the gap between high-level business goals with operational level tasks and complementing currently static business process modeling languages. The design of BOWL and a case study demonstrating its implementation are also discussed.
