- Abstract
- I analyze the text of an article that appeared in this journal in 2007 that published the results of a questionnaire in which a number of experts were asked to define the concepts of data, information, and knowledge. I apply standard information retrieval techniques to build a list of the most frequent terms in each set of definitions. I then apply information extraction techniques to analyze how the top terms are used in the definitions. As a result, I draw data-driven conclusions about the aggregate opinion of the experts. I contrast this with the original analysis of the data to provide readers with an alternative viewpoint on what the data tell us.

- Abstract
- Dominican University's Graduate School of Library and Information Science (GSLIS) was one of a funnel group of graduate schools of library and information science selected to test RDA. A seminar specifically for this purpose was conducted from August to December 2010. Fifteen students participated in the test, creating records in AACR2 and in RDA, encoding them in the MARC format, and responding to the required questionnaires. In addition to record creation, the students were also asked to submit a final paper in which they described their experiences and recommended whether or not to accept RDA as a replacement for AACR2.

- Abstract
- A recent study in information science (IS), raises important issues concerning the value of human indexing and basic theories of indexing and information retrieval, as well as the use of quantitative and qualitative approaches in IS and the underlying theories of knowledge informing the field. The present article uses L&E as the point of departure for demonstrating in what way more social and interpretative understandings may provide fruitful improvements for research in indexing, knowledge organization, and information retrieval. The artcle is motivated by the observation that philosophical contributions tend to be ignored in IS if they are not directly formed as criticisms or invitations to dialogs. It is part of the author's ongoing publication of articles about philosophical issues in IS and it is intended to be followed by analyzes of other examples of contributions to core issues in IS. Although it is formulated as a criticism of a specific paper, it should be seen as part of a general discussion of the philosophical foundation of IS and as a support to the emerging social paradigm in this field.

- Abstract
- This article reports the author's recent research in developing a holistic model for various levels of digital library (DL) evaluation in which perceived important criteria from heterogeneous stakeholder groups are organized and presented. To develop such a model, the author applied a three-stage research approach: exploration, confirmation, and verification. During the exploration stage, a literature review was conducted followed by an interview, along with a card sorting technique, to collect important criteria perceived by DL experts. Then the criteria identified were used for developing an online survey during the confirmation stage. Survey respondents (431 in total) from 22 countries rated the importance of the criteria. A holistic DL evaluation model was constructed using statistical techniques. Eventually, the verification stage was devised to test the reliability of the model in the context of searching and evaluating an operational DL. The proposed model fills two lacunae in the DL domain: (a) the lack of a comprehensive and flexible framework to guide and benchmark evaluations, and (b) the uncertainty about what divergence exists among heterogeneous DL stakeholders, including general users.

- Abstract
- RDS are usually cross-disciplinary, centralised services, which are increasingly provided at a university by the academic library and in collaboration with other RDM stakeholders, such as the Research Office. At research-intensive universities, research data is generated in a wide range of disciplines and sub-disciplines. This paper will discuss how providing discipline-specific RDM support is approached by such universities and academic libraries, and the advantages and disadvantages of these central and discipline-specific approaches. A descriptive case study on the author's experiences of collaborating with a central RDS at the University of Cambridge, as a subject librarian embedded in an academic department, is a major component of this paper. The case study describes how centralised RDM services offered by the Office of Scholarly Communication (OSC) have been adapted to meet discipline-specific needs in the Department of Chemistry. It will introduce the department and the OSC, and describe the author's role in delivering RDM training, as well as the Data Champions programme, and their membership of the RDM Project Group. It will describe the outcomes of this collaboration for the Department of Chemistry, and for the centralised service. Centralised and discipline-specific approaches to RDS provision have their own advantages and disadvantages. Supporting the discipline-specific RDM needs of researchers is proving particularly challenging for universities to address sustainably: it requires adequate financial resources and staff skilled (or re-skilled) in RDM. A mixed approach is the most desirable, cost-effective way of providing RDS, but this still has constraints.

- Abstract
- This paper presents the final phase of a research project that aims to develop a bilingual taxonomy (English and French) for the indexing of ordinary digital images. The objective of this last stage was to ask a representative sample of image searchers to complete retrieval tasks of images indexed using the new taxonomy TIIARA to measure its degree of effectiveness and efficiency. During this experiment, a sample of 60 participants were asked to indicate where in the taxonomic structure they thought they would find each one of the 30 images shown. Respondents also completed a questionnaire intended to obtain their general opinion on TIIARA and to report any difficulties encountered during the retrieval process. The quantitative data was analyzed according to statistical methods, while the content of the open-ended questions was analyzed and coded to identify emergent themes. The findings of this ultimate phase of the research project indicated that, despite the fact that some categories still need further refining, TIIARA already constitutes a successful tool that provides access to ordinary images. Furthermore, the bilingual taxonomy constitutes a definite benefit for image searchers who are not very familiar with images indexed in English, which is still the dominant language of the Web.

- Abstract
- People who are collaborating can share files in two main ways: performing Group Information Management (GIM) using a common repository or performing Personal Information Management (PIM) by distributing files as e-mail attachments and storing them in personal repositories. There is a trend toward using common repositories with many organizations encouraging workers to use GIM to avoid duplication of files and management. So far, PIM and GIM have been studied by different research communities, so their effectiveness for file retrieval has not yet been systematically compared. We compared PIM and GIM in a large-scale elicited personal information retrieval study. We asked 275 users to retrieve 860 of their own shared files, testing the effect of sharing method on success and efficiency of retrieval. Participants preferred PIM over GIM. More important, PIM retrieval was more successful: Participants using GIM failed to find 22% of their files compared with 13% failures using PIM. This may be because active organization aids retrieval: When using personally created folders, the failure percentage was 65% lower than when using default folders (e.g., My Documents), and more than 5 times lower than when using folders created by others for GIM. Theoretical reasons for this are discussed.

- Abstract
- Purpose - People often engage in different information-seeking strategies (ISSs) within a single information-seeking episode. A critical concern for the design of information retrieval (IR) systems is how to provide support for these different behaviors in a manner which searchers can easily understand, navigate and use, as they move from one ISS to another. The purpose of this paper is to describe a dialogue structure that was implemented in an experimental IR system, in order to address this concern. Design/methodology/approach - The authors conducted a user-centered experiment to evaluate the IR systems. Participants were asked to search for information on two different task types, with four different topics per task, in both the experimental system and a baseline system emulating state-of-the-art IR systems. The authors report here the results related explicitly to the use of the experimental system's dialogue structure. Findings - For one of the task types, most participants followed the search steps as predicted in the dialogue structures, and those who did so completed the task in fewer moves. For the other task type, predicted order of moves was often not followed, but participants again used fewer moves when following the predicted order. Results demonstrate that the dialogue structures the authors designed indeed support effective human information behavior patterns in a variety of ways, and that searchers can effectively use a system which changes to support different ISSs. Originality/value - This study shows that it is both possible and beneficial, to design an IR system which can support multiple ISSs, and that such a system can be understood and used successfully.

- Abstract
- This article reports the results of a study that examined relationships between primary emotions, secondary emotions, and mood in the online information search context. During the experiment, participants were asked to search Google to obtain information on the two given search tasks. Participants' primary emotions were inferred from analysis of their facial expressions, data on secondary emotions were obtained through participant interviews, and mood was measured using the Positive Affect Negative Affect Scale (PANAS; Watson, Clark, & Tellegen, 1988) prior, during, and after the search. The search process was represented by the collection of search actions, search performance, and search outcome quality variables. The findings suggest existence of direct relationships between primary emotions and search actions, which in turn imply the possibility of inferring emotions from search actions and vice versa. The link between secondary emotions and searchers' evaluative judgments, and lack of evidence of any relationships between secondary emotions and other search process variables, point to the strengths and weaknesses of self-reported emotion measures in understanding searchers' affective experiences. Our study did not find strong relationships between mood and search process and outcomes, indicating that while mood can have a limited effect on search activities, it is a relatively stable and long-lasting state that cannot be easily altered by the search experience and, in turn, cannot significantly affect the search. The article proposes a model of relationships between emotions, mood, and several facets of the search process. Directions for future work are also discussed.

- Abstract
- Purpose The purpose of this paper is to examine researchers' motivations to publish by comparing different career stages (PhD students; temporarily employed postdocs/new professors; scholars with permanent employment) with regard to epistemic, pragmatic, and personal motives. Design/methodology/approach This qualitative analysis is mainly based on semi-structured narrative interviews with 91 researchers in the humanities, social, and natural sciences, based at six renowned (anonymous) universities in Germany, the UK, and the USA. These narratives contain answers to the direct question "why do you publish?" as well as remarks on motivations to publish in relation to other questions and themes. The interdisciplinary interpretation is based on both sociological science studies and philosophy of science in practice. Findings At each career stage, epistemic, pragmatic, and personal motivations to publish are weighed differently. Confirming earlier studies, the authors find that PhD students and postdoctoral researchers in temporary positions mainly feel pressured to publish for career-related reasons. However, across status groups, researchers also want to publish in order to support collective knowledge generation. Research limitations/implications The sample of interviewees may be biased toward those interested in reflecting on their day-to-day work. Social implications Continuous and collective reflection is imperative for preventing uncritical internalization of pragmatic reasons to publish. Creating occasions for reflection is a task not only of researchers themselves, but also of administrators, funders, and other stakeholders. Originality/value Most studies have illuminated how researchers publish while adapting to or growing into the contemporary publish-or-perish culture. This paper addresses the rarely asked question why researchers publish at all.

- "As knowledge brokers, we are living in interesting times for libraries and librarians. We wonder sometimes if our traditional tools like the Dewey Decimal Classification (DDC) system can cope with the onslaught of information. The categories provided don't always seem adequate for the knowledge-discovery habits of today's patrons. They have grown accustomed to new ways for their information needs to be met, from the fire-and-forget style of a hard-to-control classic Google search to the pervasive, always-on style of Google Now, anticipating users' information needs without their having even asked a verbal question. Contrariwise, I believe that we, as librarians, could be making better use of our tools. Many (like the DDC) are a reflection of the same social and epistemological forces that brought about modernity at the turn of the last century. We as librarians are in the unique position of providing services that are as ground-breaking as these tools. As we see the need to provide unique and cutting-edge knowledge discovery to our users, I argue in this article that the DDC can play a key role in fulfilling this purpose."
