传统学科主题研究主要基于学术文本题录数据,研究对象单一。本文以SIGIR(Special Interest Group on Information Retrieval)邮件列表为切入点分别构建SIGIR邮件列表数据集和同期会议论文数据集,并在两个数据集的基础上对信息检索的主题结构和主题演化进行对比分析。研究发现,信息检索领域存在研究内容不断深入、研究方法不断增多和核心主题逐渐分裂的规律;同时还发现,SIGIR邮件列表研究主题较会议论文而言,在时序上存在一定的"领先性",通过该研究旨在揭示SIGIR邮件列表在信息检索领域的学术价值。 相似文献

高校图书馆OPAC中的分面搜索对用户体验的影响——基于不同任务的对比实验分析 总被引：1，自引：0，他引：1
[目的/意义] 研究高校图书馆OPAC中引入分面搜索技术给用户带来怎样的搜索体验。[方法/过程] 主要通过对用户在两种界面下(传统列表界面和基于列表与分面的界面)进行两种搜索任务(已知任务和探寻式任务)时所表现出的行为和喜好进行实验与观察,从搜索时间、搜索结果准确度、用户评价3方面对比分析搜索界面、搜索任务对用户搜索体验的影响。[结果/结论] 通过研究发现:相对于传统列表界面,受试者在使用基于列表与分面的界面时,搜索用时更短、用户评价更高。 相似文献

Shortly after midnight every Thursday morning, a list server in Massachusetts delivers an electronic table of contents message to the Kostoris Medical Library at the Paterson Institute for Cancer Research in Manchester, UK. The messageins details of the latest edition of the New England Journal of Medicine, complete with hyperlinks to the full text of the content online. Publishers’ electronic current awareness services have been integrated into the dissemination process of the Library service to enhance the speed of communication and access to full text content. As a means of promoting electronic journal use, a system of e‐mail delivery coupled with fast Internet access has allowed a migration from paper‐based current awareness alerting to a seamless online product. 相似文献

This study explored the household use of electronic mail. In a telephone probability sample of 881 adults, 112 adults reported they used electronic mail. This sample provided four superordinate reasons for home e‐mail use: interpersonal relationships; personal gain; business; and gratification opportunities. Overwhelmingly, home e‐mail was reported to be used for interpersonal relationship reasons regardless of user demographics. The findings suggest that e‐mail is used for the maintenance of interpersonal relationships and that gratification opportunities play an important role in home e‐mail use. 相似文献

This study examined workplace romantic relationship partners’ e‐mail practices and perceptions. Results suggest that the relationship may play an integral role in determining participants' uses and perceptions of e‐mail Workplace romantic couples used e‐mail as frequently as face‐to‐face communication to interact with romantic partners and rated it as both rich and important Participants used e‐mail for both work‐related and social tasks. In addition, participants used business e‐mail addresses for communicating with relational partners and perceived that few organizational policies existed regarding its use. Theoretically, these findings suggest the importance of studying the relationship as a factor that affects e‐mail practices and perceptions. Practically, results indicated that e‐mail may present an additional channel for enhancing communication and connectedness in workplace romantic relationships, and that organizations may need to reflect more carefully about policies concerning e‐mail use in the workplace. 相似文献

This paper gives suggestions to librarians on how to get started with electronic mail. It discusses the cost- and time-saving advantages of using electronic mail rather than TWX, United States mail, or telephones for communicating ILL requests and messages. For instance, preliminary cost data show that electronic mail is often half as expensive as TWX and costs no more than a 22 stamp. Key management concerns that must be considered when setting up electronic mail are discussed, including the need for subscribers to agree on one system. Also covered are the types of equipment that can be used with electronic mail, including print terminals. 相似文献

Interest in using electronic mail as a basis for reference service has grown considerably in recent years. This paper reviews some of the specific uses reported in the professional literature. In addition, it considers the more sophisticated capabilities of mail systems operating in compliance with the Multipurpose Internet Mail Extensions (MIME) and how systems supporting the interchange of complex, socalled "multimedia" documents may be expected to affect the use of electronic mail for library and information services. 相似文献

Commonly recognized computer-mediated communication (CMC) tools include virtual environments, bibliographic databases, listservers, newsgroups, group teleconferencing, interactive messaging systems and electronic mail. The use of these technologies in libraries has grown exponentially over the past decade. Electronic mail has emerged as an especially popular communication tool for librarians, and their colleagues and patrons. This paper explores the use of a reference department electronic mail service and its impact on reference services and librarian-client interactions. Several issues related to the implementation of CMC technologies are presented, including the maintenance and monitoring of reference electronic mail systems, the types of questions that are typically posted, and potential barriers to the implementation and use of reference e-mail. 相似文献
