Abstract

This paper presents the design and implementation of an ontology construction support tool. The Inferential Modeling Technique (IMT) (Chan, 2004), which is a technique for modeling the static and dynamic knowledge elements of a problem domain, provided the basis for the design of the tool. Existing tools lack support for modeling dynamic knowledge as defined by the IMT. Therefore, the focus of this work is development of a Protégé (Gennari, 2003) plug-in, called Dyna, which supports dynamic knowledge modeling and testing. Within Dyna, the Task Behaviour Language (TBL) supports formalized representation of the task behaviour component of dynamic knowledge. The interpreter for TBL can also enable the task behaviour representation to be run and tested, thus enabling verification and testing of the model. Dyna also supports storing the dynamic knowledge models in XML and OWL so that they can be shared and re-used across systems. The tool is applied for constructing an ontology model in the domain of petroleum contamination remediation selection.
