This study reports the results of a survey conducted at Aligarh Muslim University (AMU) to determine the extent to which Internet users are aware and make use of the Internet resources and services. The study examines the information searching behavior of Internet users. A questionnaire and follow-up interviews with the postgraduate students, research scholars and academic staff were conducted to collect data. A total of 489 questionnaires were distributed to the selected sample of eight faculties; 405 valid samples were collected. The data were analyzed according to the background of Internet users, Internet information searching behavior, use of Internet resources and services, quality of Internet information, problems of the Internet access and need for Internet literacy. The study found that the majority of respondents had a 5 year history of Internet access. The academic staff spent more time on the Internet than the students and research scholars. Although Internet search engines were the preferred information searching tool, other methods such as databases, gateways and World Wide Web (WWW) were also used. Online journals and databases were the preferred information sources among the Internet users. Respondents chose e-mail, WWW and search engines as important Internet services. About 60% of respondents believed that the good quality of information on the Internet made it a useful tool for education and research. Slow speed, lack of training and information overload were indicated as some of the factors affecting Internet usage. Further, recommendations are made to improve the use of Internet, including a well-planned Internet literacy program and preparation of subject gateways. 相似文献

Abstract Presently, eating disorders affect millions of people. Today, the media and the Internet are major publishing channels for consumer health information. Much research has found that the media may offer insufficient information on eating disorders. This research examines the quantity of adult consumer health publications on eating disorders in magazine articles and on the Internet in 1998 and investigates the effectiveness of Internet search engines. The results indicate that the resources found in popular magazines and on the Internet are not adequate, and that the Internet search engines are not effective in searching for information. 相似文献

There is a current trend to make museum collections widely accessible by digitising cultural heritage collections for the Internet. The present study takes a user perspective and explores the characteristics of online museum visitors' web search behaviour. A combination of quantitative and qualitative methods was deployed in a case study at a National Museum of Military History. Quantitatively, data from a web questionnaire survey and a user study of interactive searching behaviour were collected and analysed. Qualitatively, observation protocols were coded and analysed based on inductive content analysis. It was found that metadata elements on factual object related information, provenience, and historic context was indicated to be relevant by the majority of the respondents, characterising the group of special interest museum visitors as information hungry. Further, four main characteristics of online museum visitors' searching behaviour were identified: (a) searching behaviour has a strong visual aspect, (b) topical searching is predominantly exploratory, (c) users apply broad known item searches, and (d) meaning making is central to the search process. 相似文献

This paper notes the interrelations between the types and methods of information searches, including Internet searches. It
suggests the general approach for making a search for documents on the Internet, for example, scientific articles on information
and communication. The methods for information searches used on the Internet are characterized with placing a particular emphasis
on the method of searching with the use of search systems. General recommendations for successful conduction of searches are
advanced to increase their efficiency. The goals and problems faced by a user during scientific information searches are presented.
A user’s rights for the results of a search for scientific information are described from the standpoint of legal relations
regulated by Russian legislation. Copyright protection methods are also considered based on Russian and foreign legislation. 相似文献

Internet的发展使互联网成为一个巨大的信息库,但是信息的获取质量却停滞不前。传统的搜索引擎大都基于关键字机械匹配,因而不具备理解文档内容的能力,导致查询效率普遍不高。由于计算机可以理解RDF描述和携带的元数据的含义,因此可以做到基于内容的精确检索。为此,本文提出一种基于RDF的科技论文搜索引擎的设计与实现方案。该方案包括含词汇集设计、RDF描述生成工具、运行于服务器端的RDF描述信息收集和解析程序、基于词汇集的查询四个模块。查询结果为搜索网页的元数据显示,从而使用户对查询结果有准确的了解,可大大提高用户的搜索效率。 相似文献

Little research has explored how exactly information processes relate to their context. Context is defined as all those things which are not an inherent part of information phenomena, but which nevertheless bear some relation to these. This article addresses the issue by discussing empirical findings from a study on Internet searching and personal development. The purpose of the article is to construct a general typology for researching the links between information seeking and its context. Grounded analysis of the whole corpus revealed 11 different relationships between Internet searching and the goals of personal development. Because these seem to be quite generalizable to information seeking in other contexts (e.g., parenting or location), too, they were then abstracted into four generic relationships: detachment, unity, direction, and interaction. The classifications are offered as tools for understanding information seeking more contextually and for conducting further research in this area. 相似文献

Searches with learning intent typically require the users to interact with the searching environment and perform knowledge acquisition features such as scan, read, and process the online content to fulfill their information needs. To capture indicators from searching behaviors that could account for the knowledge gained during a Web search, a qualitative study was performed using the Concurrent Think-Aloud protocol to observe the mechanisms of transfer and map knowledge flows during 78 search sessions. Findings indicate evidence of transfer of learning in the form of sixteen online information searching strategy indicators. This research aids the understanding of how knowledge is gained during search sessions and how to identify behaviors that could indicate that learning has occurred, which could be used to represent knowledge gain on Web search engines. In this way, it can aid search engines to become not only better tools of searching, but also tools of learning. 相似文献

In recent years, the amount of video content created and uploaded to the Internet has grown exponentially. Video content has unique accessibility challenges: indexing, transcribing, and searching video has always been very labor intensive, and there were no automated ways of searching videos for specific content. New software tools that use deep learning methods are automating some of these processes, making video content more discoverable and useful. There are also many new tools for processing and manipulating video in interesting ways. This column will briefly discuss the idea of deep learning and how deep learning tools can be used to transcribe, translate, search, and even manipulate videos. It will suggest ways that librarians can use these tools to help their institutions better manage video content. It also includes a list of video-related software tools. 相似文献
