Abstract

In this article the authors present Eurovision, a textbased system for cross-language (CL) image retrieval. The system is evaluated by multilingual users for two search tasks with the system configured in English and five other languages. To the authors' knowledge, this is the first published set of user experiments for CL image retrieval. They show that (a) it is possible to create a usable multilingual search engine using little knowledge of any language other than English, (b) categorizing images assists the user's search, and (c) there are differences in the way users search between the proposed search tasks. Based on the two search tasks and user feedback, they describe important aspects of any CL image retrieval system.

Abstract

This paper presents the first large-scale investigation of the users and uses of WorldCat.org, the world's largest bibliographic database and global union catalog. Using a mixed-methods approach involving focus group interviews with 120 participants, an online survey with 2,918 responses, and an analysis of transaction logs of approximately 15 million sessions from WorldCat.org, the study provides a new understanding of the context for global union catalog use. We find that WorldCat.org is accessed by a diverse population, with the three primary user groups being librarians, students, and academics. Use of the system is found to fall within three broad types of work-task (professional, academic, and leisure), and we also present an emergent taxonomy of search tasks that encompass known-item, unknown-item, and institutional information searches. Our results support the notion that union catalogs are primarily used for known-item searches, although the volume of traffic to WorldCat.org means that unknown-item searches nonetheless represent an estimated 250,000 sessions per month. Search engine referrals account for almost half of all traffic, but although WorldCat.org effectively connects users referred from institutional library catalogs to other libraries holding a sought item, users arriving from a search engine are less likely to connect to a library.

Abstract

This article proposes that the value of information is a topic worth revisiting in the contemporary era. Although the topic has been of perennial interest to information professionals and others, since at the least the early 1980s, we believe that it is timely to revisit this question in the context of a more connected and networked environment of data, information, and knowledge. The principal argument is that existing models of information exchange and use do not sufficiently take account of the multiplicity of networked users as a source of value, for example, their implicit and explicit interactions with other users, and with the information system. We briefly review existing kinds of value that have been theorized, operationalized, and measured in the information science literature. Principally, these are the notions of information as embedded value; and information and information systems as adding value. To these notions we add the further notion of connected or cocreated value. We conclude our opinion article with a set of questions intended to orient future research into the question of the value of information in the contemporary era.
