基于ASP木马的攻击与保护

随着计算机网络的飞速发展,网络安全日益成为不可忽视的问题。如何防范网络黑客攻击,是当今热门话题。通过分析黑客攻击的手段之一ASP木马程序的运行过程和特点,根据ASP木马的原理以及IIS组件,提出通过修改服务器IIS相关组件来清除与防范ASP木马。     

JSP与JavaScript整合使用

通过Java Server Pages(JSP)和Javascfipt相结合的方法来实现服务器端参数和客户端参数相互引用，从而实现动态的WEB页面。这种方法主要是将由JSP数据库端传来的相关信息“预存”到JavaScfipt函数中，利用JavaScfipt函数在客户端执行来动态交换信息且减少网络流量，减少对数据库的访问次数。     

基于领域本体的Web页面信息抽取

由于当前信息抽取系统因知识库结构和内容的不同带来的搜索质量问题,将本体引入信息抽取中,有助于信息抽取系统对领域内的概念和概念之间的联系的统一认识,为用户提供更有价值的信息。提出了基于本体的文本信息抽取算法,通过本体元素描述抽取的文本信息。最后,利用此算法对某领域样本Web页面进行抽取并分析。实验表明性能有所提高。     

基于Web的开放实验室管理系统

以培养能力为主的素质教育，使实验在教育中的比重不断加大，从而对实验教学管理工作也提出了更高的要求。本系统是从实验教学管理的实际管理需要出发，针对实验教学管理的现状，开发了一个综合，实用的信息管理系统。     

Helping Users Help Themselves

Abstract

Traditionally, distance students have completed their research in an electronic environment and off-campus librarians have strived to meet the needs of these students using a variety of methods. Today our students are familiar with the Web as a medium of interaction, and library usage has changed as a result of electronic services on the Internet. Given the dramatic increase in usage of our Off-Campus Library Services' Web site, a survey was conducted to determine whether the content of the site and the services offered were simple and useful to our users. This paper presents the results of the survey as well as a discussion of the changes to the site as a result of feedback from students.     

“Be All That You Can Be”

Abstract

Library school provides librarians with a good background in library science, but to be a professional reference librarian, continuous improvement must be sought. Professionalism can include developing basic employee skills, supporting library standards, participating in university and library functions; presenting papers; and publishing. Being sensitive to communication skills can impact how a librarian is perceived by library users. Image does play a role in the effectiveness of the library professional.

Professional reference librarians must market themselves by being visible on campus, in the community, and on the Internet. Being a professional librarian is an opportunity for personal growth and educating the public about a very exciting discipline.     

The Availability of Faculty Publication Databases from Library Web Pages

Abstract

Faculty publication databases or author bibliographies offer libraries an opportunity to provide services to users. Initially, these databases remained initiatives of special libraries in the health-sciences fields. Librarians used the publication information derived from these databases to compile lists for annual reports. However, the advent of new technologies, especially the Web, prompted numerous libraries to develop faculty publication databases for their institutions. The author conducted a survey of various listservs to discover the history and development of these databases. The results illustrate the popularity of Web-based faculty publication databases. The motivation for their creation varied, but most respondents emphasized the desire to highlight the research activities of their institutions. In addition, the content of materials included in the databases and the definition of faculty also varied, depending on the type of library. Librarians reported a wide range of software employed in the development of these databases highlighting their creation by librarians with various levels of programming skills. Moreover, additional features included in these projects underscore the potential for librarians to provide added value from this service. Finally, while institutional repositories seemingly present similar content, publication databases differ in their focus on a citation format that offers a solution to items without copyright permission for full-text accessibility.     

增量式关键资源页面判定树

本文针对互联网上信息的日益海量增长的情况,在评述前期算法的基础上,提出了一种关键资源页面判定树的增量式更新算法.新算法使用Web页面的链接分析方法,选择合适的Web页面属性,并基于反例的统计信息来构造判定树的测试属性值,采用ID5R算法来处理训练样本不断增长的关键资源页面判定的机器学习任务.同时设计了适合于该算法的剪枝策略,它通过引入并实时更新反例样本比率并在其值低于抑制因子时停止分裂的办法,避免了树的过度增长与抗嗓能力差、泛化情况糟糕的情况.实验表明增量式更新算法能更高效地生成关键资源页面判定树.最后讨论了该算法的应用领域.
