论NT用户组在代理软件中的应用

代理服务器广泛应用于网络中, 它能实现Internet 的快速访问, 节约网络带宽和IP 地址, 减少网络堵塞, 提高网络安全, 但如果配置不当, 便会给用户带来很大的经济损失, 本文以Microsoft  Proxy2. 0 为例, 详细介绍一下对出站访问用户的控制。     

Experience,Challenges, and Opportunities of Being Fully Embedded in a User Group

Embedded librarian models can assume different forms and levels, depending on patron needs and a library’s choice of delivery services. An academic health sciences library decided to enhance its service delivery model by integrating a librarian into the College of Pharmacy, approximately 250?miles away from the main library. This article describes the embedded librarian’s first-year experience, challenges, and opportunities working as a library faculty in the college. The comparison of one-year recorded statistics on preembedded and postembedded activities demonstrated the effectiveness and impact of such an embedded librarian model.     

基于用户群体影响的协同过滤推荐算法

协同过滤是推荐系统中广泛使用的推荐技术,对推荐结果可解释强.基于用户的协同过滤是一种重要的系统推荐方法,用户评分数据的极端稀疏性制约着系统的推荐质量.针对上述情况,提出一种基于用户群体影响的协同过滤推荐算法.首先,定义了用户群体的概念并根据群体影响提出两条相应准则;然后,计算用户相似性时,不仅考虑了用户个体之间的相似性,而且考虑了用户所处群体之间的相似性.该算法不仅可以更加精确地刻画用户之间相似度,而且一定程度上增强了推荐系统的稳定性.实验结果表明,该算法能有效地提高系统的推荐质量,而且满足所提出的两条准则.

Library User Instruction in the Curriculum:

Teaching patrons to use library resources unaided has long been recognized as highly desirable, yet the education of reference librarians to do this important instruction has been scattered and haphazard. Slow to develop and emerge as a separate course in library school curricula, this article reports that the situation has now changed, due primarily to the organized efforts and perseverance of practitioners and library and information science educators.

Tools of Academic Library Assessment: the User Survey

ABSTRACT

Academic libraries are taking a closer look at how well they are serving the needs of their users. As a result assessment activities become more important. In this column, the authors will focus on and describe one major tool of assessment—the user survey.     

Personas: Stepping Into the Shoes of the Library User

Personas are researched-based user archetypes which can help uncover gaps, highlight new opportunities, and inform the functionality of a space, resource, or service. Personas are a useful tool for organizations, such as libraries, which are interested in improving the user experience, since they tap into users' expectations, behaviors, and attitudes. This column will explain what personas are, the advantages and disadvantages of using personas, and where personas are used. A list of resources for exploring and creating personas is also provided.     

Giving the User a Voice: Capturing Impact Through the Interjection of User Impact Surveys into the Information Retrieval Workflow

This article discusses a novel approach being developed at Oregon State University Libraries to move beyond usage statistics as a method to capture the larger impact of a specific set of resources for faculty. Utilizing a custom developed survey application, Oregon State University collection development librarians are able to modify the proxy workflow, inserting a point-of-use survey, allowing data collection to occur at the point of need and only on specific resources of interest.     

天津图书馆联盟用户管理系统用户分析与鉴别模块设计及其功能研究

以天津图书馆联盟为例,论述了图书馆联盟用户管理系统的用户分析与鉴别模块的主要内容及其功能。用户分析模块主要采取职业分类的标准对用户信息进行分析,而用户鉴别主要通过分析用户特征,将他们分成不同的用户群,从而便于图书馆了解用户的需求及其规律,制定服务计划,建立个性化主动服务机制。
