With the extensive application of ontology in many fields, it is more and more important to build practical ontologies. However, available editing tool for Chinese ontologies is rare, so efficient ontology development tool which is designed for Chinese is needed. In this paper, we present a tool for editing and Visualization of Chinese ontologies on MVC mode, which reads and writes Chinese ontologies with the protégé-owl API, and implements ontology visualization with prefuse library. The experiments show that the design can edit and realize the visualization of chinese ontologies efficiently, which provides a more convenient platform for chinese ontology researchers.
