我们描述了一种独立于域的方法，以扩展SemRep覆盖范围超出生物医学领域。SemRep是一个最初为生物医学文本设计的自然语言处理应用程序，它使用统一医学语言系统（UMLS（c））提供的知识源。为了支持其他领域的知识，需要对系统进行本体和术语扩展。我们通过开发一个以前不支持的领域的语义表示来扩展SemRep的应用程序。这是通过适应著名的本体工程阶段，并将它们与UMLS知识源SemRep至关重要的依赖。虽然扩展SemRep覆盖范围的过程已成功应用于早期的项目，本文详细介绍了我们遵循的逐步方法和实现的机制。医学信息学领域的案例研究说明了本体工程阶段如何适应与UMLS的最佳集成。我们提供了定性和定量的结果，这表明我们的方法的有效性和实用性。爱思唯尔公司出版
We describe a domain-independent methodology to extend SemRep coverage beyond the biomedical domain. SemRep, a natural language processing application originally designed for biomedical texts, uses the knowledge sources provided by the Unified Medical Language System (UMLS (c)). Ontological and terminological extensions to the system are needed in order to support other areas of knowledge. We extended SemRep's application by developing a semantic representation of a previously unsupported domain. This was achieved by adapting well-known ontology engineering phases and integrating them with the UMLS knowledge sources on which SemRep crucially-depends. While the process to extend SemRep coverage has been successfully applied in earlier projects, this paper presents in detail the step-wise approach we followed and the mechanisms implemented. A case study in the field of medical informatics illustrates how the ontology engineering phases have been adapted for optimal integration with the UMLS. We provide qualitative and quantitative results, which indicate the validity and usefulness of our methodology. Published by Elsevier Inc.
