Web2.0对编目工作的影响

Web2．0的研究和讨论已经引起了图书情报界的巨大热情。Web2．0作为下一代的互联网，会对各个方面造成巨大的影响，编目工作也不例外。本文从Web2．0对编目环境、编目技术、编目方式、编目内容等方面的影响进行了讨论，指出Web2．0环境下的编目工作将为知识组织的实现举有力的支持。     

发展中的新一代OPAC

发展中的新一代OPAC,深入挖掘OPAC内部已经积聚并时刻生成着的大量可资利用的信息.在Web2.0环境下,新一代OPAC进一步从外部获取信息,向用户提供服务;同时,通过向互联网开放OPAC的书目及相关信息,让用户在自己熟悉的网络环境中使用OPAC,改善用户使用OPAC的体验,致力于吸引用户更多地利用图书馆及其服务.     

Web挖掘的伦理问题研究

Web挖掘中涉及到的伦理问题有:对用户隐私权的侵犯,对用户个性特征的忽视,知识产权问题,信息安全问题。解决这些问题应从多方面入手:制订伦理守则,运用技术手段践行伦理要求,用户对隐私权等信息权利认真追究,管理部门加强监管。参考文献16。

Dimensions of variability in embedded operating systems

Design, implementation, and re-engineering of operating systems are still an ambitious undertaking. Despite, or even because, of the long history of theory and practice in this field, adapting existing systems to environments of different conditions and requirements as originally specified or assumed, in terms of functional and/or non-functional respects, is anything but simple. Especially this is true for the embedded systems domain which, on the one hand, calls for highly specialized and application-aware system abstractions and, on the other hand, cares a great deal for easily reusable implementations of these abstractions. The latter aspect becomes more and more important as embedded systems technology is faced with an innovation cycle decreasing in length. Software for embedded systems needs to be designed for variability, and this is in particular true for the operating systems of this domain. The paper discusses dimensions of variability that need to be considered in the development of embedded operating systems and presents approaches that aid construction and maintenance of evolutionary operating systems.

基于Web服务的语义网格与异构资源的推送研究

阐述构建教学参考信息服务系统的思路：利用Web服务为基础实现技术,初步完成教参系统语义网格,实现各种架构数据库的透明访问及与各院系资料室功能上的对接;在此基础上,利用语义网格实现异构资源的推送集成,并分析服务质量评价体系的内容和相关参数。     

基于UDDI扩展的Web服务信誉度模型研究

通过对现有UDDI规范进行扩展，提出一个Web服务信誉度评估模型，通过引入量化的概念，采用客户反馈、主动监视的机制，对UDDI中注册的Web服务信誉度进行动态评估和调整，实现基于信誉度约束的Web服务发现机制。     

基于统计-规则方法的网页层次分类技术研究

基于统计的自动分类是网页层次分类中常用的技术，但其有不足之处，主要表现为当子类之间出现严重的特征交叉现象时，分类精确率将大大下降。而网页层次分类的本质决定了同一大类下的子类存在许多相同的特征。针对这一局限性，结合基于规则的自动分类技术的优点，提出一种基于统计-规则方法的网页层次分类技术。实验表明，基于统计-规则方法的网页层次分类技术能够获得比较理想的分类效果。     

The accessibility of Chinese local government Web sites: An exploratory study

With the rapid development of Chinese e-government, Chinese citizens are encouraged to access e-government services as their convenience. However, the accessibility of Chinese e-government Web sites has been overlooked. This research study tries to provide an overview of the accessibility of Chinese local government Web sites. Three hundred twenty-four Chinese local government Web sites were examined to find out how accessible they are with reference to the Web Content Accessibility Guidelines 1.0 (WCAG) published by the World Wide Web Consortium (W3C). This research found that all the surveyed Chinese e-government Web sites failed one or more W3C's accessibility measures and thus many disabled Chinese people may have substantial problems to access them. Several valuable recommendations are made based on the research findings and the China's actual conditions.     

Web多媒体相关文本提取研究

基于结构对Web网页区域分割与语义识别，实现网页语义理解，给出Web多媒体相关文本的定义，并结合其分布特点，采用个体级、区域级、网页级三级分析方法分别进行提取，从而实现Web多媒体相关文本准确提取。
