摘　　要：为提高资源描述的规范化及标准化,提升资源之间的互操作能力,各类型词表不断被创建及使用,词表重用已成为资源描述中的关键问题。本文从资源描述的基本结构出发,基于数据模型和资源标注两个阶段对词表层、模式层及数据层进行详细分析;探讨词表层、概念层两种重用类型,认为当前用户更关注于词表层重用,概念层重用将随着词表生态环境的完善得到进一步发展;以数据模型中的类与属性为划分对象,以RDF三元组形式入手对词表重用实现方式进行深入研究,有助于明确各种方式之间的差异性及适用环境,能够有效地指导用户运用已有词表对数据集的类、属性及其取值范围进行准确描述,从而提升数据集的质量。The purpose of the resource description is to add meaningful data to the described objects so that machine and human users can effectively identify find and discover various types of resources.In order to improve thenormalization and standardization of resource description and enhance the interoperability between resources varioustypes of vocabulary are constantly created and used to describe resources and can express semanticcontent contained in resources as much as possible.Vocabulary reuse needs to select proper classes and attributes from the existing vocabularies to define the internal and external characteristics of the describ edobjects and use shared terms to define the common mode of information exchange.This will realizeth e accurate description and formal representation of datasets to improve the interoperability between datasets and avoid ambiguity and conflict of expressions.In the process of data modeling whether the datasetcan be described accurately whetherthe connection between data sets can be established clearly and whether the human-computer readable and comprehensible environment can be provided largely depend onthe reuse of vocabularies.The paper anal yzes the basic structure of resource description and divides its processinginto two phases data model andresource annotation.According to the function it is deeplyclassified into vocabulary layer schema layer and the data layer.Then it discusses the types and implementationmethods of vocabulary reuse by taking the bibliographic data of the British Library as an example and shows the differences and applicable environments of various ways guiding the users of vocabulary reu se to accurately describe classes attributes and value ranges of datasets by using existing vocabulary soas to improve the quality of datasets and offer the basis for their further application.There aretwo types of vocabulary reuse vocabulary layer reuse and conceptual layer reuse occurred at the modeling stage ac cording to different users.focus.The vocabulary layer reuse fo
