Research on the General Architecture of Ontology Learning System

This paper proposes a unified, open, extensible, domain independent, and scalable architecture of ontology learning systems. The unified functional structure and standardized access interfaces are defined for ontology learning systems. Our architecture consists of resource layer and five main function modules: resource management module, general resource read/write module, data preprocessing module, ontology extraction module and ontology evaluation and editing module. Functions and constitutions of resource layer and all modules are depicted in detail. Its main goal is to provide support for reuse of ontology learning methods and components, ontology industrialization producing, periodical ontology refinement.
