ABSTRACT:
To overcome the limitations of text-based de-scriptions a HAZOP ontology has been proposed that provides a basic set of standard concepts and terms The development of the ontology uses the Upper level Ontology, SUMO (The Suggested Upper Merged Ontology) and a Process Engi-neering Ontology, that define general-purpose terms and act as a foundation for more specific domains. The ontology is developed so that en-gineers can build new concepts out from the basic set of concepts. This paper evaluates the proposed ontology by means of use cases that measure the performance in finding relevant information used and produced during the safety analyses. In this paper, the extraction of knowledge is performed using JTP (An object oriented Modular Reason-ing System) that is used for querying the ontol-ogy.
