Abstract: Le RDF (Resource Description Framework) est une infrastructure qui permet le codage, l'echange et la reutilisation de metadonnees structurees (metadonnees du Web)

Abstract: In today's fast-paced world, anecdotal evidence suggests that information tends to inundate people, and users of information systems want to find information quickly and conveniently. Empirical evidence for convenience as a critical factor is explored in the data from two multi-year, user study projects funded by the Institute of Museum and Library Services. The theoretical framework for this understanding is founded in the concepts of bounded rationality and rational choice theory , with Savolainen's (2006) concept of time as a context in information seeking , as well as gratification theory , informing the emphasis on the seekers' time horizons. Convenience is a situational criterion in peoples' choices and actions during all stages of the information-seeking process. The concept of convenience can include their choice of an information source, their satisfaction with the source and its ease of use, and their time horizon in information seeking. The centrality of convenience is especially prevalent among the younger subjects (“millennials”) in both studies, but also holds across all demographic categories—age, gender, academic role, or user or non-user of virtual reference services. These two studies further indicate that convenience is a factor for making choices in a variety of situations, including both academic information seeking and everyday-life information seeking, although it plays different roles in different situations.

Abstract: Purpose – This paper seeks to understand how users know when to stop searching for more information when the information space is so saturated that there is no certainty that the relevant information has been identified.Design/methodology/approach – Faculty, undergraduate and graduate students participated in focus group interviews to investigate what leads them to satisfice their information needs.Findings – Academic library users describe both qualitative and quantitative criteria, which lead them to make rational choices determining when “enough” information satisfices their need. The situational context of both the participants' specific information need and their role in academic society affects every stage of their search – from the selection of the first resource, to ongoing search strategies, to decisions on how much information is enough.Originality/value – These findings broaden the scope of earlier user research, which tends to focus on the more static views of habitual information‐seeking and ...

Abstract: The Dublin Core is a 15-element metadata element set intended to facilitate discovery of electronic resources Originally conceived for author-generated description of Web resources, it has also attracted the attention of formal resource description communities such as museums and libraries

Abstract: The shortcomings and limitations of Library of Congress Subject Headings (LCSH) are examined, focusing on problems of subject term specificity, inconsistent identification and selection of concepts as subject headings, retention of outmoded headings, inadequate cross-reference structure, and low level of indexing exhaustivity. These problems are attributable to both Cutter's Rules for a Dictionary Catalog (the theoretical model upon which LCSH are based), and the unsystematic manner in which LC has applied Cutter's Rules in constructing entries for its subject catalog. Methods of improving subject access in libraries, for both on-line and printed catalog environments, are discussed.
