【摘要】 数字图书馆是一种基于计算机网络，功能强大的管理分布式、海量的数字化多媒体资源的信息存储和检索系统。数字图书馆所面向的领域远远超出了传统图书馆的范围，国内外已经对数字图书馆开展了许多研究工作，并推出了自己的数字图书馆产品，如IBM数字图书馆、中国数字图书馆、超星数字图书馆等等。但是，目前还没有一个可以按照用户需求建立其自己的数字图书馆的产品，因此我们开发研制了一种基于机群并行计算环境的并行数字图书馆系统，它可以帮助用户根据自己的数据特点轻松地建立自己的数字图书馆。 本文在借鉴了现有数字图书馆人机交互系统特点的基础上提出了一种新的基于计算机机群并行环境人机交互子系统的设计方法，该方法克服了其他数字图书馆人机交互系统的缺陷，提供给用户标准而友好的交互界面，使用户不需特殊训练就能掌握各种文本的检索操作，快速准确地获取信息。此外，本文还提出了并行数字图书馆系统中文本的保护策略，很好地保护了作者的权益。更多还原

【Abstract】 Digital Libraries are an extension and enhancement of information storage and retrieval systems based on computer network, which manipulate digital data in any medium and exist in distributed networks. The field of digital libraries have features not possible in traditional libraries, thereby extending the concept of library far beyond physical boundaries. A lot of research work have done at home and abroad, and they have developed their digital library such as IBM digital library,China digital library, Super Star digital library.But there is not any digital library products that user can build himself digital library based on their data character by these digital library products.So a parallel digital library system based on parallel computing environment has been developed by our group.Users can build their digital library used it easily.This paper presents a new design method of Human-Computer interaction subsystem,it gets over the lack of Human-Computer interaction subsystem in other digital library. Our subsystem provide a standard and friendly interface in order to let users finish all kinds of query operation no training and get information quickly and exactly.In addition to,we present a method of protecting resource in digital library,it protects the copyright of publisher commendably.更多还原
