本文介绍了路易斯安那州立大学州立大学网站的描述性研究。这项研究的目的是在给定的时间点上获得用户人口统计数据和对网站的满意度的一些想法，并测试网站的导航系统。我们希望了解谁在使用该网站，他们为什么使用它，以及他们对网站导航的满意程度。然后，我们分配任务（搜索已知的项目）的主题，以更好地确定在何种程度上该网站的导航系统促进定位信息在网站上。导航系统的评价基于正确点击与错误点击和返回按钮点击总和的比率。可以将该比率与检索已知项目所需的某个预定最佳点击次数进行比较。本研究的意义是理论和实践。这些模型的内部，基于Web的信息搜索可能会使用其他机构的类似性质，寻求提供有用的网站，为他们的用户，以及提供一个基础，为进一步研究的问题，基于Web的信息检索系统的开发。* 1999年秋天，路易斯安那州立大学（LSU）图书馆网站包含超过6000层：以html、htm或txt扩展名结尾的文件。该网站提供了数据库、期刊文章和书籍全文、图书馆工作人员和工作时间的信息、预订图书馆教室的表格等。由于1999年一天中最低时段的使用率高于1995年最高时段的使用率，很明显，该网站越来越频繁地用于多种目的。为了更好地利用图书馆网站进行研究，有必要对研究者的网站搜索行为进行分析。路易斯安那州立大学图书馆网站在1999年春季学期开始时重新设计。在重新设计之前，路易斯安那州立大学图书馆网络小组进行了图书馆范围的论坛，向所有图书馆员工开放。网络组要求论坛参与者填写一份简短的调查，讨论他们认为网站的主要问题是什么。此外，网络小组向与会者介绍了各种图书馆网站，促进了对其他图书馆网站的方法和风格的讨论，并记录了评论意见。最后，网络小组向与会者展示了新网站的几个原型（仅第一层），并征求反馈意见。根据论坛的反馈，设计了五个新的网页原型，网络小组要求图书馆员工提供更多的反馈。网络组的研究导致了路易斯安那州立大学图书馆网页的新设计，使用了七个标题的目录结构：LOLA-在线目录，电子资源，关键链接，一般信息，服务，图书馆部门和校园图书馆，搜索图书馆的网页。论坛上指出的主要问题是导航：人们并不总是知道在哪里点击才能找到他们要找的东西。新的设计试图通过几种方式来解决这个问题：新的目录结构，每个标题下都有相关的链接，使导航更加直观;搜索这个网站功能，以前在网站的更深处提供，被前移到前面一层;以及A到Z：网站内容被添加到“一般信息”标题下，以详细列出网站可能搜索的网页和主题用户.在新设计实施后不久，在主页上添加了一个Web调查链接，以调查用户对网站设计的看法，从而启动了我们的研究。问题理想的图书馆网站以一种直接有效的方式将读者引导到他们正在寻找的任何信息。网站的组织、措辞和内容在引导用户获得所需信息方面很重要。…
This paper presents a descriptive study of the Louisiana State University Libraries' Web site. The intent of the study was to gain some idea of user demographics and satisfaction with the site at a given point in time and to test the site's navigation system. We wished to find out who was using the site, why they were using it, and to what extent they were satisfied with the site's navigation. We then assigned tasks (searching for known items) to subjects to better determine the extent to which the site's navigation system facilitated locating information on the site. Evaluation of the navigation system was based on a ratio of correct clicks to the sum of incorrect and back button clicks. This ratio may be compared to some predetermined optimal number of clicks needed to retrieve a known item. The implications of this research are both theoretical and practical. These models of in-house, Web-based information seeking may be used by other institutions of a similar nature that seek to provide useful Web sites for their users as well as to provide a basis for further research on the problem of Web-based development of information retrieval systems. ********** In fall 1999, the Louisiana State University (LSU) Libraries Web site contained more than six thousand layers: files ending with the extensions html, htm, or txt. The site provides access to databases, full-text journal articles and books, information about the library staff and hours, forms to reserve library classrooms, and more. With usage during the low time of day in 1999 greater than that for the peak time in 1995, it is obvious that the Web site is used more and more frequently for many purposes. In order to facilitate successful research through the libraries' Web site, it is necessary to analyze researchers' behavior when searching the Web site. The LSU Libraries Web site was redesigned at the start of the spring 1999 semester. Prior to the redesign, the LSU Libraries Webgroup conducted library-wide forums open to all library employees. The Webgroup asked the forum participants to fill out a brief survey, discussing what they thought the major problems of the Web site were. Furthermore, the Webgroup presented various library Web sites to the participants, facilitating a discussion on the methods and styles of other library Web sites, and taking notes on the comments. Finally, the Webgroup presented the participants with several prototypes of a new Web site (first layer only) and solicited feedback. Based on the feedback from the forums, five new prototypes for Web pages were designed, and the Webgroup asked the library employees for more feedback. The Webgroup research resulted in a new design for the LSU Libraries Web page, using a directory structure with seven headings: LOLA--online catalog, Electronic Resources, Key Links, General Information, Services, Library Department and Campus Libraries, and Search the Libraries' Web Pages. The major problem specified at the forums was navigation: people did not always know where to click to find what they were looking for. The new design attempted to solve this problem in several ways: the new directory structure with related links under each heading made navigation more intuitive; a Search this Site feature, formerly available deeper within the site, was moved forward to the front layer; and an A to Z: Web Site Contents was added under the General Information heading to alphabetically list Web pages and topics likely to be searched for by Web site users. Shortly after the new design was implemented, a link to the Web survey was added to the home page to survey users about the Web site design, initiating our research. Problem The ideal library Web site leads its patrons to whatever information they are seeking in a straightforward and efficient manner. The organization, wording, and content of the Web site are important in leading its users to desired information. …
