While ontology development is beneficial, it is very costly and time consuming. In order to reduce this cost as well as to increase the accuracy and quality of ontology development, researchers have proposed different methodologies. The goal of these methodologies is to present a systematic manual or semi-automated development of ontologies, while each differs and has its strengths and weaknesses. In this paper, after reviewing current methodologies, we present a new integrated collaborative methodology for ontology development, and compare it with the existing ones. This new system, called Ontirandoc, has been used in two ontology development projects and its accuracy has been evaluated.
