A Collaborative Development of Ontology-Based Knowledge Bases

The paper describes the model of collective development of knowledge bases (KB), based on ontologies, and knowledge base editor that implements this model. In addition, the paper discusses the requirements for knowledge base editors that support collaborative KB building. The model proposed uses asynchronous editing mode as default and knowledge base version control system. The model supports integration of notifications and discussions into the development process, as well as the presence of the flexible roles and permissions management system to support groups of developers and experts with various levels of ontological competence and areas of expertise. The implementation of this model in KB editor integrated into the thematic intelligent scientific Internet resource (ISIR) is described. Collaborative KB building is supported by version control subsystem that constantly monitors the consistency of the knowledge base, and by the notification subsystem intended to make development transparent for users and to integrate the discussions to the development process.
