Abstract It’s hard to search the needed knowledge in the Internet, because the same knowledge usually have different descriptions and name when knowledge management system takes mass knowledge in the Internet as source. Knowledge was described with ontology and different descriptions of the same knowledge were connected by using the similar ontology to resolve the problem. A prototype of web knowledge management system based on ontology (O-WKMS) was developed in order to reduce the difficult of ontology establishment and decrease the ontology maintenance costs. The system structure model and process model were presented. The technology for ontology establishment of collaborative based on self-organization principle was described in detail, and ontology-based semantic search was realized with Lucene engine. Primary application shows that the enterprise’s knowledge base can be further ordered and the efficiency for web knowledge discovery, management and retrieval can be improved with the knowledge ontology establishment of collaborative and self-organization mode.

知识本体协同建立和应用
针对当知识管理系统以互联网上存在的丰富海量知识作为知识源时,因同一知识的不同描述造成所需知识的查找困难问题,提出利用本体对知识进行描述,使同一知识的不同描述通过相似本体关联起来.为了降低本体的建立难度以及维护成本,研究并开发了一种基于本体的web知识管理系统(O-WKMS)原型. 给出了系统结构模型、过程模型,详细描述了基于自组织原理的本体协同建设技术,结合Lucene引擎,实现基于本体的语义搜索.初步应用表明,该系统通过本体的自组织的协同建设,可以有效地促进企业知识库的有序化,提高企业进行web知识的发现、管理和搜索的效率.
