在许多大型应用领域中出现的一个主要问题是不同信息系统的术语之间的差异。一个组织的信息系统使用的术语可能与另一个组织使用的术语不一致，即使它们在同一个域中。这种情况显然阻碍了沟通和信息共享，降低了业务效率。这种性质的问题可以通过使用受控词汇表（CV）来克服，CV是一个概念系统，它巩固和统一了一个领域的术语。然而，简历很大，很复杂，很难理解。本文提出了一种基于语义网络的CV表示为面向对象数据库（OODB）的方法。我们称这种表示为面向对象的词汇库（OOVR）。该方法基于对源CV的结构分析和分区。作为OOVR的CV的表示提供了数据库管理系统的典型支持级别和促进对CV的结构和内容的理解的抽象视图。在讨论了该方法的理论方面后，我们将其应用于MED和InterMED，两个现有的医疗领域的简历。一个程序，称为OOVR发电机，自动执行我们的方法进行说明。MED-OOVR和InterMED-OOVR都是使用OOVR Generator创建的，并且都存在于商用OODBMS ONTOS之上。来自InterMED的OOVR目前可在网络上获得。
A major problem that arises in many large application domains is the discrepancy among terminologies of different information systems. The terms used by the information systems of one organization may not agree with the terms used by another organization even when they are in the same domain. Such a situation clearly impedes communication and the sharing of information, and decreases the efficiency of doing business. Problems of this nature can be overcome using a controlled vocabulary (CV), a system of concepts that consolidates and unifies the terminologies of a domain. However, CVs are large and complex and difficult to comprehend. This paper presents a methodology for representing a semantic network-based CV as an object-oriented database (OODB). We call such a representation an Object-Oriented Vocabulary Repository (OOVR). The methodology is based on a structural analysis and partitioning of the source CV. The representation of a CV as an OOVR offers both the level of support typical of database management systems and an abstract view which promotes comprehension of the CV's structure and content. After discussing the theoretical aspects of the methodology, we apply it to the MED and InterMED, two existing CVs from the medical field. A program, called the OOVR Generator, for automatically carrying out our methodology is described. Both the MED-OOVR and the InterMED-OOVR have been created using the OOVR Generator, and each exists on top of ONTOS, a commercial OODBMS. The OOVR derived from the InterMED is presently available on the Web.
