在移动搜索日趋普遍和手机应用(APP)数量迅速增长的背景下,研究用户移动搜索行为与APP交互之间的关联,可以掌握用户在移动互联网环境下的搜索习惯,为用户提供更好的移动搜索服务。本文通过对在校大学生15天的手机日志挖掘和调查,分析了大学生的移动搜索会话、查询式与APP交互之间的关系,以及搜索时间、搜索主题与APP类型要素之间的关系。研究发现,大学生在移动搜索会话中,会较多地发生与其他APP的交互,其搜索途径更加丰富,查询式提交过程中的跨应用特征较为明显;大学生使用不同APP以及搜索不同主题信息时,搜索持续时长存在差异;大学生搜索参考类、购物类等信息时会偏向使用垂直类搜索引擎,而使用浏览与搜索类APP和社交类APP时,搜索主题十分广泛;大学生对同一主题类型信息的搜索,搜索时间不同也会影响APP的使用类型。图7。表2。参考文献30。 相似文献

[目的/意义] 搜索引擎是用户访问网络资源的重要入口,识别用户搜索策略有助于发现用户搜索的认知规律,让搜索引擎更好地理解用户搜索。[方法/过程] 采用Microsoft顺序分析与聚类分析算法对用户搜索日志中的搜索时间进行分析,识别用户利用搜索引擎时普遍采用的搜索策略,并概括不同类型搜索策略的特征。[结果/结论] 用户在搜索中存在“快速消费”策略、“试探”策略、“探索”策略和“终止与确认”策略,不同策略在搜索时间、浏览次数、用户认知过程等方面表现出明显的差异。 相似文献

通过对大学生进行“搜索引擎搜索语法使用情况”问卷调查,根据调查统计数据得出大学生对搜索引擎搜索语法的使用整体不高的结论。作为搜索引擎主要使用者的大学生应该学会利用能有效提高搜索有效性和精确度的搜索语法。搜索引擎运营商和图书馆都应为大学生掌握搜索语法做出努力。 相似文献

信息搜索用户的学习交互是包含用户-搜索系统交互、用户-搜索引擎结果页面交互、用户-搜索内容交互、用户-其他用户交互等维度的综合概念体系。协同搜索情境则进一步增加了用户学习交互的复杂性。文章设计一项信息搜索实验,以探究不同社交关系类型和协作效能水平对协同搜索用户学习交互的影响,为理解信息搜索用户的协作学习机制奠定基础;使用双因素方差分析法、Mann-Whitney U非参数检验与质性分析法,综合分析实验当中产生的数据。研究发现：社交关系类型不能对协同搜索用户的学习交互产生影响;协作效能对协同搜索用户的网页链接深度、知识讨论次数和知识共享次数具有主效应;社交关系类型与协作效能对用户的网页平均浏览时间具有交互作用：高协作效能水平下,朋友组的网页平均浏览时间多于陌生人组,低协作效能水平下,陌生人组的网页平均浏览时间多于朋友组。相关研究结论能够激励信息搜索用户对协作学习的重视,并为支持良好学习体验的协作信息检索系统的设计提供借鉴。 相似文献

近年来,搜索引擎对人类认知能力产生的负面影响正引起越来越多的社会关注,而学术界时这个问题的探讨还局限在思辨层面.本文选取当代大学生这个从小就使用搜索引擎的群体,来初步窥探搜索引擎的认知影响.问卷调查的数据显示,搜索引擎已成为大学生不可或缺的学习工具,然而搜索而来的海量信息却未必能与大学生的认知结构融会贯通;控制实验则发现:在信息需求强烈的情况下,使用搜索引擎所获得的认知效果明显不如使用书本所获得的认知效果,而且,同样是使用搜索引擎,男生所获得的认知效果明显不如女生. 相似文献

AbstractThis study aims to investigate the perception of faculty members at King Abdulaziz University (KAAU) towards online search service in the Jeddah main campus. Survey methods were used to determine the demands of the faculty members from different faculties and to find out the subject areas for which more search requests are made. The data for this study were collected by administering a specially designed questionnaire to all the chairmen of departments within each faculty. Personal interviews were conducted with the library staff responsible for the online search service at the KAAU Central Library. Analysis of relevant data indicates that out of 73 questionnaires delivered to chairmen, 51 completed questionnaires were received, a 70% response rate. Further analysis revealed that 139 requests were made by 11 faculties and institutions during 1989 and 1990. Forty-five percent of respondents used online search service to conduct personal research. 相似文献

Abstract A current discussion topic among academic librarians is opening the library 24/7. Concern frequently focuses on whether the patrons per hour justify this use of resources. In other words, “If we open the library, will the users come?” In response to student demand for 24/7, researchers at the University of Oklahoma conducted a pilot study of late-night use at the main library. More than 80 percent of the respondents reported they were satisfied with the current hours. Seventy-four percent indicated their primary reason for coming to the library was to study. The preliminary results will be useful in designing follow-up studies. As a result of the pilot survey at Bizzell Memorial Library (the main library), the University Libraries administration has determined that extending hours to 24/7 will only be offered during finals week. 相似文献

Physician's referral letter bibliographic service: a new method of disseminating medical information
N J Lodico 《Bulletin of the Medical Library Association》1973,61(4):422-425
At the time this paper was written a unique trial project for disseminating medical literature to physicians had been in operation for six months (October 1971-April 1972) at the Virginia Medical Information System. Doctors in the state who referred patients to the Medical College of Virginia received short lists of references relevant to the problems of their patients as described in referral letters sent them by MCV consultants. Doctors receiving such lists were offered free photocopies of the articles cited if they could not obtain them locally. Of some 700 reference lists sent out, VAMIS received 12(1/2) percent direct responses, and 22 percent of respondents to a questionnaire reported obtaining articles elsewhere. Ninety percent of the respondents favored the service and approved of its method. Funding problems necessitated revision of the service in the summer of 1972. Presently the service is provided only on request of the referring physician. 相似文献

The ready availability of on-line information resources may have resulted in a change in biomedical researchers' patterns of use of resources which are not available on-line. To investigate the occurrence and extent of these changes, the distribution patterns by date of citations from every major article published in ten high-impact biomedical journals in 1959, 1969, and 1979 were analyzed. The analysis showed that in all three time periods approximately 89% of the references fell within fifteen years of the journal's publication date. In 1979, however, references were more evenly distributed over the fifteen years available on-line. In addition, a marked increase was noted in the number of cited references per article. To verify the citation analysis results, a random selection of senior authors of 1979 papers was surveyed. Major findings showed that: (1) approximately 29% of the respondents had used a computer bibliography to prepare the paper which was analyzed; (2) approximately 73% of those using a computer search used it in combination with a manual search; and (3) less than 22% of all respondents had never used a computer-generated bibliography. 相似文献

通过分析NSTL用户检索表达式发现:全文检索和字段检索的使用比例相当;精确检索只占4.08%，布尔检索表达式占38.44%，并且随着单个检索表达式中布尔运算符数量的增加，相应检索表达式的数量呈现指数递减现象，其中使用“and”运算符的比例达91%;用户最倾向使用的前5个检索字段依次为标题、关键词、出版年、作者和来源文献题名。从这些现象可以看出NSTL用户的部分检索特征，对于系统的改进具有重要意义。 相似文献

A survey to determine attitudes toward end-user searching was made at Loyola University's Medical Center Library using MEDIS, an online full-text and bibliographic medical retrieval system. One hundred forty-one completed questionnaires were analyzed for this report. Information was collected on user familiarity with computers, end-user training, system use, mechanics of searching, and attitudes toward future use. Computer familiarity was highest among the faculty users. Ninety percent of the respondents saw librarians as a crucial agent in training and in providing end-user assistance. Respondents identified five major reasons for using the system: helpfulness, convenience, time savings, rapid feedback, and presentation of needed information. Searching the MEDLINE database rather than the full-text database was the search method of choice. Continued use of both mediated and end-user searching was intended by most of the respondents. Survey results support a perceived need for end-user searching and confirmed recommendations of the Association of American Medical Colleges on medical information science skills. 相似文献

This article reports a survey on the use of Internet services and resources in the engineering colleges of Punjab and Haryana states of India. Data were collected by using a questionnaire and follow-up interviews with Internet users, i.e. teachers and students of engineering colleges. The response rate was 80.8%. Results showed that all the respondents make frequent use of the Internet because they have access either at college or at home. The survey revealed that the majority of the respondents, i.e. 65.6%, access the Internet from college or their workplace. More than 75% of the respondents use the Internet services mainly for educational and research purposes. Google and Yahoo search engines are found to be more widely used than other search engines. More than 70% of the respondents feel that the Internet is useful, informative, easy to use, inexpensive and time saving. 相似文献
