【摘要】 World Wide Web是一个巨大的分布式信息系统，拥有数十亿的网页和数百万的用户，互操作性是其成功的关键。如何有效的组织Internet上的各种信息资源，成为数字图书馆发展中的重要问题，并由此引申的信息系统与知识组织体系的互操作问题引起了数字图书馆研究人员的重视，提出和研发了新的技术和标准来解决这一问题。本文就在分析知识组织体系的互操作的技术和发展上，着重介绍了XML Topic Maps (XTM主题图)技术，并提出了以XTM主题图作为语义互操作的基础实现知识组织体系互操作的系统结构，最后试验了基于XTM主题图的搜索引擎的实现。 本文包括四个部分，第一部分介绍了目前数字图书馆的知识组织体系。第二部分在分析信息系统互操作的基础上对知识组织体系的互操作的技术和发展进行分析。第三部分介绍了描述知识组织体系的元数据，它既是知识组织体系的描述工具，也是实现互操作的基础。第四部分着重介绍了XTM主题图技术，以及利用XTM实现知识组织体系互操作的范例和系统，提出了基于XTM的互操作模型，并试验了以XTM组织信息的搜索引擎的实现。在最后还总结了该试验的不足和知识组织体系互操作的发展。更多还原

【Abstract】 World Wide Web is a huge distributed information system which owns billions of web pages and millions of users, so the interoperability is the key to its success. How to effectively organize all kinds of information resources on internet has become an important problem in the development of digital libraries, from which comes up another problem - the interoperability of information systems and knowledge organize systems. Digital librarians attach importance to these problems and have put forward new technologies and slanders to solve them.This essay analyses the technology and development of the interoperability of knowledge organize systems , mainly introduces XML Topic Maps, presents a system framework which helps realize the interoperability of knowledge organize systems based on XTM Topic Maps, and experiments the realization of the XTM-based search engine.This essay includes four parts.The first part gives a gentle introduction to the latest knowledge organize systems of digital libraries.After analyzing the interoperability of information systems, the second part goes further to explain the technology and development of the interoperability of knowledge organize systems.The third part introduces such metadata as Resource Description Framework (RDF) and SHOE, which are both the describing tools and operation basis ofknowledge organize systems.The fourth part, the main part of the essay, focuses on XTM Topic Maps, presenting some interoperability examples and systems which have been realized by the use of XTM. Then, the essay introduces an interoperability model, examines the realization of the XTM-based search engine. Finally, it points out some shortcomings of this experiment and sums up the development of the interoperability of knowledge organize systems.更多还原
