| 摘 要： | 领域知识和术语的复杂性和多样性是影响知识管理系统成功的关键。本体将在开放式知识管理系统中起到至关重要的作用 ,它通过定义精确的共享术语 ,以提供某一特定领域可重用的知识。但是这些知识并不是静态的 ,而是随着时间的推移不断演化。领域的改变、自适应不同的任务、或概念模型的改变都要求本体的变更。本体演化的支持在本体的分布式开发和应用中非常重要。本文首先对知识管理中本体演化的原因和所带来的问题进行分析 ,然后讨论了本体演化管理的系统框架和应用实例 ,着重强调了本体标识和本体变化机制的定义 ,并对今后的研究工作进行了展望

| Abstract: | The complexity and diversity of domain knowledge and terminology is the major hurdle for a successful operation of knowledge management system. Ontologies are set to play a key role in the KM system, as they provide a reusable piece of knowledge about a specific domain. However, those pieces of knowledge are not static, but evolve over time. Domain changes, adaptations to different tasks, or changes in the conceptualization require modifications of ontology. Support for ontology evolution becomes very important in distributed development and use of ontologies. The paper first analyzes the causes and the consequences of ontologies evolution in knowledge management. Then the system framework and application experiment of ontology evolution management are discussed. Ontologies identification and the definition of ontology change mechanisms are our focuses. Finally we propose the future work of ontology evolution management. |
