中文摘要：	2014年南开大学正式引入EDS资源发现系统，用以全面揭示图书馆馆藏资源，方便用户通过一个统一的检索界面迅速获取所需信息，其结果就是被称为“南开搜索”的南开大学资源发现系统。本研究旨在考察南开搜索作为一个“一站式”信息查询工具的可用性，为南开搜索的持续改进提供建议。 本文以卡罗尔·巴纳姆的可用性测试要点为依据，选取12名不同专业/领域的在校师生，使用实验法辅之以访谈法和问卷调查法，将用户置于具体的情境下，通过观察用户在给定情境下的信息检索过程，分析发现系统的可用性，通过用户的切身体验参与未来“南开搜索”的改进。具体来说，本研究主要通过各项子任务的完成情况及出现失败/失误较多的关键点衡量系统各功能的可用性；通过任务完成时间及点击次数的前后对比衡量“南开搜索”的易用性；通过查全率查准率、用户满意度和半结构化访谈的内容衡量系统的检索效果。 调查结果显示，从资源类型来看，“南开搜索”针对馆藏图书的查询效果最好，针对馆藏其他资源（如购置的数据库资源）的查询效果相对逊色。在系统的易用性方面，“南开搜索”比较容易使用，这表现为新手能够快速掌握它的使用方法。但在检索效率方面，与用户习惯上采用的检索工具（非“一站式”工具）相比，“南开搜索”没有明显优势，资源覆盖率较低。与用户之前习惯使用的检索工具相比，过半数人表示更加信赖之前的工具。虽然有75%的参与者表示以后会继续使用“南开搜索”，但很少有人将其视为独立的检索工具，认为“南开搜索”起到的是补充和辅助的作用。 对于上述现象，笔者对其产生的原因从用户信息行为、用户信息素养、图书馆及图书馆员、系统供应商与内容提供商这四个角度进行分析和归纳，并提出了相应建议。在检索界面方面，本研究根据用户追求简单和直接获取全文的信息行为趋向，提出了简化系统检索界面设计、将用户最需要的功能放在最关键的位置、统一“下载全文”的名称等建议。在用户信息素养培训方面，本研究提出了应重视对基本检索术语、检索技能、高质量资源识别能力的教学，并发挥专业导师的指导作用。在图书馆配套服务方面，本研究建议图书馆及馆员可以推出简短的教学视频；针对不同的用户群体制定不同的图书馆教学计划；实事求是，列明“南开搜索”包含的资源范围，不做模糊宣传；追求透明性等等。根据用户追求可靠的检索结果、希望实现资源全覆盖的信息行为趋向和用户期待，建议图书馆引入中文资源发现系统；促进图书馆与供应商之间进行合作，修订全文术语，将链接及位置标准化；提供多种排序方式以及多与用户进行可用性测试，了解用户需求，增强自身的竞争力和不可替代性等。
英文摘要：	In 2014, Nankai University formally introduced the EDS resource discovery system to fully reveal the library's collection resources and facilitate users to quickly obtain the required information through a unified search interface. The result is the Nankai University resource discovery system called "Nankai Search". This research aims to examine the usability of Nankai Search as a "one-stop" information query tool and provide suggestions for the continuous improvement of Nankai Search. Based on the main points of Carol Barnum’s usability test, this article selects 12 teachers and students in different majors/fields, and uses experimental methods supplemented by interviews and questionnaires to put users in specific situations. By observing the user's information retrieval process in a given context, analyzing and discovering the usability of the system, and participating in the future improvement of "Nankai Search" through the user's personal experience. Specifically, this research mainly measures the usability of each function of the system through the completion of various subtasks and the key points where there are more failures/mistakes; the ease of use of "Nankai Search" is measured by the comparison of task completion time and the number of clicks before and after Measure the retrieval effect of the system through the recall rate, user satisfaction, and the content of semi-structured interviews. The survey results show that, in terms of resource types, "Nankai Search" has the best query effect on collections of books, while its query effect on other resources in the collection (such as purchased database resources) is relatively inferior. In terms of the ease of use of the system, "Nankai Search" is relatively easy to use, which shows that novices can quickly master its use. However, in terms of retrieval efficiency, "Nankai Search" has no obvious advantages compared with the retrieval tools used by users (not "one-stop" tools), and the resource coverage rate is low. Compared with the search tools that users were accustomed to using before, more than half of people said they trusted the previous tools more. Although 75% of the participants said that they would continue to use "Nankai Search" in the future, few people regard it as an independent search tool and think that "Nankai Search" plays a supplementary and auxiliary role. For the above phenomenon, the author analyzes and summarizes the causes from four perspectives: user information behavior, user information literacy, library and librarian, system supplier and content provider, and puts forward corresponding suggestions. In terms of the search interface, this research proposes to simplify the system search interface design, put the functions most needed by users in the most critical position, and unify the name of "download the full text" based on the user's trend of pursuing simple and direct access to full text information. In terms of user information literacy training, this research proposes that the teaching of basic search terms, search skills, and the ability to identify high-quality resources should be emphasized, and professional instructors should play a guiding role. In terms of library services, this research suggests that libraries and librarians can launch short teaching videos; develop different library teaching plans for different user groups; seek truth from facts, list the range of resources included in "Nankai Search", and don’t do it. Vague publicity; pursuit of transparency, etc. According to the user’s pursuit of reliable search results, the desire to achieve full coverage of information behavior and user expectations, it is recommended that libraries introduce a Chinese resource discovery system; promote cooperation between libraries and suppliers, revise full text terminology, and standardize links and locations ; Provide a variety of sorting methods and more usability tests with users to understand user needs, enhance their own competitiveness and irreplaceability, etc.
