电子知识表示以正式本体和不太正式的参考词汇（例如 UMLS）的形式变得越来越普遍。临床知识库的开发者需要重用这些资源。这种重用需要新一代的本体开发和管理工具。很少或没有计算机科学经验的医学专家需要工具来开发知识库，并提供直接从正式知识库和参考术语导入知识的能力。然后，需要将从不同资源导入的知识库部分合并或相互对齐，以便链接相应的术语、消除冗余、解决逻辑冲突。我们讨论了本体管理工具的要求，这些工具将实现不同知识源的互操作性。我们的小组正在开发一套基于 Protégé-2000 环境的知识库管理工具，用于本体开发和知识获取。我们在这里详细描述了一个这样的工具：一个用于将来自远程知识源（例如 UMLS）的信息合并到 Protégé 知识库中的应用程序。
Electronic knowledge representation is becoming more and more pervasive both in the form of formal ontologies and less formal reference vocabularies, such as UMLS. The developers of clinical knowledge bases need to reuse these resources. Such reuse requires a new generation of tools for ontology development and management. Medical experts with little or no computer science experience need tools that will enable them to develop knowledge bases and provide capabilities for directly importing knowledge not only from formal knowledge bases but also from reference terminologies. The portions of knowledge bases that are imported from disparate resources then need to be merged or aligned to one another in order to link corresponding terms, to remove redundancies, to resolve logical conflicts. We discuss the requirements for ontology-management tools that will enable interoperability of disparate knowledge sources. Our group is developing a suite of tools for knowledge-base management based on the Protégé-2000 environment for ontology development and knowledge acquisition. We describe one such tool in detail here: an application for incorporating information from remote knowledge sources such as UMLS into a Protégé knowledge base.
