This paper presents a preliminary description of the database schema and associated procedures that are the foundation for the "engine" that will produce Meta-1.2. Meta-1.2 is the next incarnation of the Metathesaurus, which is one of the principal components of the National Library of Medicine's Unified Medical Language System (UMLS). We use the word "engine" as a generic term that includes a database and the programs that operate on it. While this design builds heavily upon previous work, it incorporates some major changes in philosophy. A major hypothesis is that the simple representation described here is suitable for any controlled vocabulary in the biomedical domain. Indeed, this hypothesis is central to a strategy for producing future versions of the Metathesaurus and for supporting collaboration with people who wish to contribute additional terms and relationships to the Metathesaurus. Another change involves the representation of classes and relationships. The revised database schema includes an explicit representation of the source or "authority" for relationships, which is analogous to the way that the sources of terms have been represented since the first version of the Metathesaurus. A sequence of steps utilizing the new representations to produce the Metathesaurus is presented.
本文初步描述了数据库模式及相关程序，它们是生成Meta-1.2的“引擎”的基础。Meta-1.2是叙词表的下一版本，叙词表是美国国立医学图书馆统一医学语言系统（UMLS）的主要组件之一。我们使用“引擎”一词作为通用术语，它包括一个数据库以及在其上运行的程序。虽然此设计在很大程度上基于先前的工作，但它在理念上纳入了一些重大变化。一个主要假设是，此处描述的简单表示适用于生物医学领域的任何受控词汇表。事实上，这一假设对于生成叙词表未来版本以及支持与希望为叙词表贡献更多术语和关系的人员进行协作的策略至关重要。另一个变化涉及类和关系的表示。修订后的数据库模式包括对关系的来源或“权威”的显式表示，这类似于自叙词表第一版以来术语来源的表示方式。本文还介绍了利用新表示来生成叙词表的一系列步骤。
