Research on Collaborative Ontology Development Method Based on Lock Granularity

Ontology is a method of expressing knowledge. It is essential for multiple engineers to develop a collaborative ontology. However, current tools, techniques and methodologies for developing collaborative ontology system are inadequate. Against this background, a collaborative ontology development method based on lock-granularity is proposed in this paper. The method aims to control the lock-granularity flexibly, and improve the locking reliability and integrity in collaborative environment. Correlation among nodes and users' locking authority ensure the collaborative ontology construction in the method. At the same time, the relativity threshold and the semantic radius are also used to control the lock-granularity. Then, two relevant algorithms are given. Finally, the experimental results show that the method is efficient and feasible..
