A Process Ontology for Business Intelligence

Abstract

Abstract. This paper presents oXPDL, a process interchange ontology based on the stan-dardised XML Process Definition Language (XPDL). XPDL was introduced to allow pro-cess model exchange between information systems, most of which are based on proprietary workflow models. In its current form, XPDL allows only syntactic vendor-specific exten-sions without clear semantics, has only limited support for informational and organisational modelling aspects and cannot be interlinked to existing standardised knowledge bases. Our process interchange ontology oXPDL explicitly models the complete semantics of XPDL process models in a standard Web ontology language. The oXPDL ontology has a strong focus on the reuse and integration of existing standard ontologies such as PSL, RosettaNet, SUMO and eClassOWL. We present the ontology and the accompanying tool to automat-ically translate an XPDL process model to its corresponding oXPDL. The oXPDL process models may be used for integrated process analysis, by querying and reasoning over multi-ple models, each of which may originate from different information systems, in combination with business rules described in background ontologies.
