Process ontologies contain organization's process elements which are related to the business activities, in a structured format. Once organizations establish process ontologies, searching process information as well as discovery, modeling and automation become more efficient. Process ontologies are frequently developed from organizational resources such as guidelines, regulations and procedures by interpreting the document, discovering the process information and building the ontology. The studies depict that the development of process ontologies can be partially automated. However, a significant success factor in this automation is the language of the document and the tools available to interpret the written text in a given language. In this study, we conducted an exploratory case study in order to analyze the potential of process ontology discovery in different languages. We applied the process ontology discovery method we have developed for guidelines written in English and Turkish and compared the success rates. We also discuss the requirements for process discovery automation.
