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..
