Summary Among the many ways the World Wide Web has changed libraries are the additional tools gained by librarians and library users for answering reference questions. In addition to the growing number of licensed resources providing the full text of articles from newspapers, magazines, academic journals, and reference works are the millions of free Web sites offering an incredible variety of information about everything. Locating the most useful of these sites and organizing them into categories on library Web sites can be enormously beneficial both to patrons and libraries. After deciding to make their sites reference portals, librarians must make a number of important decisions. 相似文献

Abstract As the World Wide Web continues to grow, the problem of locating quality resources becomes progressively more acute. While search engines can be invaluable tools for locating certain specific types of information, the technology is more limited in dealing with broad enquiries. This article outlines the development of the BUBL LINK / 5:15 service, which combines powerful browse and search options with a selective approach toresource discoveryand cataloging, and describes how the service overcomes some of the problems in locating Internet resources. 相似文献

There are a number of multimedia tasks and environments that can be collaborative in nature and involve contributions from more than one individual. Examples of such tasks include organising photographs or videos from multiple people from a large event, students working together to complete a class project, or artists and/or animators working on a production. Despite this, current state of the art applications that have been created to assist in multimedia search and organisation focus on a single user searching alone and do not take into consideration the collaborative nature of a large number of multimedia tasks. The limited work in collaborative search for multimedia applications has concentrated mostly on synchronous, and quite often co-located, collaboration between persons. However, these collaborative scenarios are not always practical or feasible. In order to overcome these shortcomings we have created an innovative system for online video search, which provides mechanisms for groups of users to collaborate both asynchronously and remotely on video search tasks. In order to evaluate our system an user evaluation was conducted. This evaluation simulated multiple conditions and scenarios for collaboration, varying on awareness, division of labour, sense making and persistence. The outcome of this evaluation demonstrates the benefit and usability of our system for asynchronous and remote collaboration between users. In addition the results of this evaluation provide a comparison between implicit and explicit collaboration in the same search system. 相似文献
