    Abstract
    The present essay is based on research funded by the German Ministry of Economics and Technology and carried out by the Munich School of Philosophy (Prof. Godehard Brüntrup) in cooperation with the IT company Comelio GmbH. It is concerned with setting up the philosophical framework for a systematic, hierarchical and categorical account of questions and answers in order to use this framework as an ontology for software engineers who create a tool for intelligent questionnaire design. In recent years, there has been considerable interest in programming software that enables users to create and carry out their own surveys. Considering the, to say the least, vast amount of areas of applications these software tools try to cover, it is surprising that most of the existing tools lack a systematic approach to what questions and answers really are and in what kind of systematic hierarchical relations different types of questions stand to each other. The theoretical background to this essay is inspired Barry Smith's theory of regional ontologies. The notion of ontology used in this essay can be defined by the following characteristics: (1) The basic notions of the ontology should be defined in a manner that excludes equivocations of any kind. They should also be presented in a way that allows for an easy translation into a semi-formal language, in order to secure easy applicability for software engineers. (2) The hierarchical structure of the ontology should be that of an arbor porphyriana.

    Abstract
    Drawing on the ideas of process philosophy, this study elaborates the nature of information-seeking process by approaching them as temporal developments. To this end, a conceptual analysis was made by comparing key models which approach information seeking as stage-based and cyclic processes. The nature of such processes was scrutinized by devoting attention to two main aspects, that is, the temporal order in which the constituents of information seeking appear during the process, and the changes occurring in the constituents. Stage-based approaches draw on linear time concept by conceptualizing such processes as sets of consecutive activities progressing toward a final point. Cyclic approaches conceptualize information-seeking processes as sets of iterative activities which may be repeated. The findings suggest that stage-based and cyclic approaches should not be opposite approaches; rather, they complement each other. However, cyclic models emphasizing the importance of feedback loops have gained more popularity in the modeling of web searching, whereas the interest in the development of stage-based approaches has decreased since the 1990s.

    Abstract
    The aim of this study was to measure the efficiency of the system by which scientists worldwide communicate results to each other, providing one measure of the degree to which the system, including all media, functions well. A randomly selected and representative sample of 246 active research scientists worldwide was surveyed. The main measure was the reported rate of "late finds": scientific literature that would have been useful to scientists' projects if it had been found at the beginning of these projects. The main result was that 46% of the sample reported late finds (±6.25%, p0.05). Among respondents from European Union countries or other countries classified as "high income" by the World Bank, 42% reported late finds. Among respondents from low- and middle-income countries, 56% reported late finds. The 42% rate in high-income countries in 2009 can be compared with results of earlier surveys by Martyn (1964a, b, 1987). These earlier surveys found a rate of 22% late finds in 1963-1964 and a rate of 27% in 1985-1986. Respondents were also queried about search habits, but this study failed to support any explanations for this increase in the rate of late finds. This study also permits a crude estimate of the cost in time and money of the increase in late finds.

    Abstract
    With the use of machine learning and other advances, modern information search systems make it easy for searchers to access information to meet their most frequent information needs. Building from Kuhlthau's concepts of exploration and differentiating, this article argues that along with the benefits of greater accessibility, these advances impede the development of information literacy, conceptualized as processes for planning, accessing, judging and communicating information. It is argued that information literacy emerges during interaction with search systems and modern system designs hide or render unworkable the contextual information needed for the judgment processes of information literacy. In response to these concerns, the article contributes desiderata for new designs that facilitate the discovery, navigation and use of context information.

    Abstract
    Large amounts of health-related information of different types are available on the web. In addition to authoritative health information sites maintained by government health departments and healthcare institutions, there are many social media sites carrying user-contributed information. This study sought to identify the types of drug information available on consumer-contributed drug review sites when compared with authoritative drug information websites. Content analysis was performed on the information available for nine drugs on three authoritative sites (RxList, eMC, and PDRhealth) as well as three drug review sites (WebMD, RateADrug, and PatientsLikeMe). The types of information found on authoritative sites but rarely on drug review sites include pharmacology, special population considerations, contraindications, and drug interactions. Types of information found only on drug review sites include drug efficacy, drug resistance experienced by long-term users, cost of drug in relation to insurance coverage, availability of generic forms, comparison with other similar drugs and with other versions of the drug, difficulty in using the drug, and advice on coping with side effects. Drug efficacy ratings by users were found to be different across the three sites. Side effects were vividly described in context, with user assessment of severity based on discomfort and effect on their lives.

    Abstract
    In the context of online question-answering services, an intermediary clarifies the user's needs by eliciting additional information. This research proposes that these elicitations will depend on the type of question. In particular, this research explores the relationship between three constructs: question types, elicitations, and the fee that is paid for the answer. These relationships are explored for a few different question typologies, including a new kind of question type that we call Identity. It is found that the kinds of clarifications that intermediaries elicit depend on the type of question in systematic ways. A practical implication is that interactive question-answering services-whether human or automated-can be steered to focus attention on the kinds of clarification that are evidently most needed for that question type. Further, it is found that certain question types, as well as the number of elicitations, are associated with higher fees. This means that it may be possible to define a pricing structure for question-answering services based on objective and predictable characteristics of the question, which would help to establish a rational market for this type of information service. The newly introduced Identity question type was found to be especially reliable in predicting elicitations and fees.

    Abstract
    Keeping up to date with research developments is a central activity of academic researchers, but researchers face difficulties in managing the rapid growth of available scientific information. This study examined how researchers stay up to date, using the information journey model as a framework for analysis and investigating which dimensions influence information behaviors. We designed a 2-round study involving semistructured interviews and prototype testing with 61 researchers with 3 levels of seniority (PhD student to professor). Data were analyzed following a semistructured qualitative approach. Five key dimensions that influence information behaviors were identified: level of seniority, information sources, state of the project, level of familiarity, and how well defined the relevant community is. These dimensions are interrelated and their values determine the flow of the information journey. Across all levels of professional expertise, researchers used similar hard (formal) sources to access content, while soft (interpersonal) sources were used to filter information. An important "pain point" that future information tools should address is helping researchers filter information at the point of need.

    Abstract
    Purpose - Uncovering faculty members' conceptions of Information Literacy (IL), as well as exploring their perceptions with regard to the importance given to a previously defined set of core IL competences grouped into four categories: searching, evaluation, processing and communication and dissemination. Ascertaining the possible differences among the five knowledge branches (arts and humanities, sciences, social and legal sciences, health sciences, and technical disciplines); and understanding the importance granted to a set of learning improvement initiatives by the faculty. The paper aims to discuss these issues. Design/methodology/approach - The survey was completed by a set of faculty members from the University of Granada (Spain). Data were collected using the IL-HUMASS survey. The research is based on subjective data, first approached from a descriptive point of view. Later, data correlation, analysis and non-parametric tests were used with the goal of finding significant differences of faculty perceptions among the relevant academic areas. Findings - Results suggest that more than half of the surveyed faculty have what the authors define as an Academic Concept of IL. The IL categories of communica\tion and dissemination and searching were graded in significance by the staff as being "very important," while those of evaluation and processing were assigned a slightly lesser rating of "important." Results suggest that IL awareness falls into two broad groups differentiated by subject discipline: those from health sciences, social and legal sciences and arts and humanities representing the first group, and sciences and technical disciplines the other. Research limitations/implications - This approach address the subjective status of faculty concepts in a single university, but also in all knowledge branches. Future research is needed. Originality/value - This is one of the few papers regarding faculty perceptions of IL.

    Abstract
    The article reports the findings of a content analysis study of 16 student-group proposals for a grade eight history project. The students listed their topic and thesis in the proposal, and information in support of their thesis. The study's focus is this topic-to-thesis transition. The study's conceptual framework is Kuhlthau's six stage ISP Model's transition from exploring information in Stage 3 to formulating a focus or personal perspective on the assignment topic in Stage 4. Our study coding scheme identifies elements of the students' implicit knowledge in the 16 proposals. To validate implicit knowledge as a predictor of successful student performance, implicit knowledge was coded, scored, and then the correlation coefficient was established between the score and the students' instructors' marks. In Part 2 of the study we found strong and significant association between the McGill coding scores and the instructors' marks for the 16 proposals. This study is a first step in identifying, operationalizing, and testing user-centered implicit knowledge elements for future implementation in interactive information systems designed for middle school students researching a thesis-objective history assignment.

    Abstract
    Adopting an intradisciplinary perspective, this article evaluates the information-seeking behavior of academics from different subfields of physics and astronomy. It investigates the effect of interdisciplinarity (reliance on the literature of other subjects) and the scatter of literature on two aspects of the information-seeking behavior: methods used for keeping up-to-date and for identifying articles. To this end a survey of 114 PhD students and staff at the Department of Physics and Astronomy at the University College London was carried out. The findings showed that the subfields that are more interdisciplinary or have a more scattered literature are more likely to use general search facilities for finding information. The study also showed that cross-disciplinary use of the literature is not necessarily an indicator of scattered literature. The study reveals intradisciplinary differences among physicists and astronomers in terms of their information-seeking behavior and highlights the risk of overlooking the characteristics of information-seeking behavior of specialized subject communities by focusing on very broad subject categories.

    Abstract
    Purpose - The purpose of this paper is to introduce the term Information Literacy 2.0 as a subset of information literacy, to describe its development and significance and give an outline of its underlying theoretical assumptions. Design/methodology/approach - The paper first examines the grounds for the possible re-conceptualizations in the field of information literacy and identifies the current developments in the information universe as the principal drive for perception shifts. Based on a literature review and a descriptive analysis of contrasting features of library user education, information literacy and Information literacy 2.0, the paper highlights the main foci of paradigm shifts. Findings - The paper found that the new meaning and understanding of the central conceptions in information literacy are shifting the focus of classical information literacy towards Information literacy 2.0. Many of the aspects of current information literacy practices originate from a print-based culture, which is incongruent with the transient and hybrid nature of digital environments. These radically changing environments are causing the appearance of anomalies in the information literacy paradigm, which could effectively be resolved through the introduction of a sub-concept of information literacy. Practical implications - The article specifies the possibilities for putting theoretical conceptualizations of Information literacy 2.0 into practice by determining the range of shifts in information literacy activities and identifying how new practices differ from the earlier approaches. Originality/value - The study attempts to advance the research field of information literacy by proposing a new outlook on information literacy through the integration of its underlying theoretical conceptions and practical applications.

    Abstract
    Dass eine erfolgreiche Suche nach im Unternehmen vorhandenen Informationen oftmals schwieriger zu bewerkstelligen ist als eine Suche im Internet, wird in der Privatwirtschaft zunehmend als Problem gesehen. Enterprise Search ist eine Strategie, diesem Problem zu begegnen. In einer Studie mit explorativem Charakter wurde der Frage nachgegangen, wie es um den Stand unternehmensweiten Suche in österreichischen Unternehmen bestellt ist. m Rahmen einer Onlinebefragung wurden dazu im März / April 2009 469 Unternehmen befragt. Es beteiligten sich 104 Unternehmen. Das entspricht einem Rücklauf von 22 %. Dieser Beitrag gibt Auskunft über Status quo der unternehmensweiten Informationsorganisation und -suche in Österreich und benennt unternehmens- bzw. personengebundene Faktoren, die darauf Einfluss haben. Im einzelnen werden Ergebnisse zu folgenden Aspekten präsentiert: Regelung der Informationsorganisation; Anreicherung unstrukturierter Informationen mit Metadaten; Probleme bei der Suche nach unternehmensinternen Informationen; täglicher Zeitaufwand für die Suche; vorhandene, wünschenswerte und benötigte Suchfunktionalitäten; Zufriedenheit mit der Suche und der Informationsorganisation Unternehmen.

    Abstract
    Purpose - The purpose of this paper is to elaborate how source preference criteria are defined in the context of everyday projects that require the seeking of problem-specific information. More specifically, to find out how information seekers explain their preference criteria by characterizing the perceived strengths and weaknesses of diverse sources. Design/methodology/approach - The approach takes the form of qualitative content analysis of empirical data gathered by semi-structured interviews with 16 prospective home buyers in 2008. The source preference criteria were elicited by making use of the construct of information source horizon. Findings - Networked sources were favoured most strongly, followed by printed media, human sources and organizational sources. Content of information was the primary source preference criterion. Availability of information was a fairly important criterion, while user characteristics, usability of information and situational factors were fairly marginal in this regard. In the definition of the preference criteria, more emphasis was placed on the perceived strengths than weaknesses of sources. Positive qualities such as "provides updated information" were referred to particularly while judging the relevance of the networked sources. Negative qualities like "outdated information" were primarily associated with printed media and organizational sources. Research limitations/implications - The study is exploratory, drawing on a relatively small sample recruited through a web-based service. Thus, the findings cannot be generalized to prospective home buyers. Practical implications - Prospective home buyers tend to favour web-based information sources and services. They should provide the customers with detailed information about the property, including photos. Originality/value - The paper specifies the picture of user-defined relevance judgment in the context of everyday life information seeking.

    Abstract
    Purpose - This research seeks to gain a detailed understanding of how researchers come across information serendipitously, grounded in real-world examples. This research was undertaken to enrich the theoretical understanding of this slippery phenomenon. Design/methodology/approach - Semi-structured critical incident interviews were conducted with 28 interdisciplinary researchers. Interviewees were asked to discuss memorable examples of coming across information serendipitously from their research or everyday life. The data collection and analysis process followed many of the core principles of grounded theory methodology. Findings - The examples provided were varied, but shared common elements (they involved a mix of unexpectedness and insight and led to a valuable, unanticipated outcome). These elements form part of an empirically grounded process model of serendipity. In this model, a new connection is made that involves a mix of unexpectedness and insight and has the potential to lead to a valuable outcome. Projections are made on the potential value of the outcome and actions are taken to exploit the connection, leading to an (unanticipated) valuable outcome. Originality/value - The model provides researchers across disciplines with a structured means of understanding and describing serendipitous experiences.

    Abstract
    We report a naturalistic interactive information retrieval (IIR) study of 18 ordinary users in the age of 20-25 who carry out everyday-life information seeking (ELIS) on the Internet with respect to the three types of information needs identified by Ingwersen (1986): the verificative information need (VIN), the conscious topical information need (CIN), and the muddled topical information need (MIN). The searches took place in the private homes of the users in order to ensure as realistic searching as possible. Ingwersen (1996) associates a given search behaviour to each of the three types of information needs, which are analytically deduced, but not yet empirically tested. Thus the objective of the study is to investigate whether empirical data does, or does not, conform to the predictions derived from the three types of information needs. The main conclusion is that the analytically deduced information search behaviour characteristics by Ingwersen are positively corroborated for this group of test participants who search the Internet as part of ELIS.

    Abstract
    Granularity is a novel concept for presenting information in search result interfaces of hierarchical query-driven information retrieval systems in a manner that can support understanding and exploration of the context of the retrieved information (e.g., by highlighting its position in the granular hierarchy and exposing its relationship with relatives in the hierarchy). Little research, however, has been conducted on the effects of granularity of search results on the relevance judgment behavior of engineers. Engineers are highly motivated information users who are particularly interested in understanding the context of the retrieved information. Therefore, it is hypothesized that the design of systems with careful regard for granularity would improve engineers' relevance judgment behavior. To test this hypothesis, a prototype system was developed and evaluated in terms of the time needed for users to find relevant information, the accuracy of their relevance judgment, and their subjective satisfaction. To evaluate the prototype, a user study was conducted where participants were asked to complete tasks, complete a satisfaction questionnaire, and be interviewed. The findings showed that participants performed better and were more satisfied when the prototype system presented only relevant information in context. Although this study presents some novel findings about the effects of granularity and context on user relevance judgment behavior, the results should be interpreted with caution. For example, participants in this research were recruited by convenience and performed a set of simulated tasks as opposed to real ones. However, suggestions for further research are presented.

    Abstract
    The quality of online health information for consumers has been a critical issue that concerns all stakeholders in healthcare. To gain an understanding of how quality is evaluated, this systematic review examined 165 articles in which researchers evaluated the quality of consumer-oriented health information on the web against predefined criteria. It was found that studies typically evaluated quality in relation to the substance and formality of content, as well as to the design of technological platforms. Attention to design, particularly interactivity, privacy, and social and cultural appropriateness is on the rise, which suggests the permeation of a user-centered perspective into the evaluation of health information systems, and a growing recognition of the need to study these systems from a social-technical perspective. Researchers used many preexisting instruments to facilitate evaluation of the formality of content; however, only a few were used in multiple studies, and their validity was questioned. The quality of content (i.e., accuracy and completeness) was always evaluated using proprietary instruments constructed based on medical guidelines or textbooks. The evaluation results revealed that the quality of health information varied across medical domains and across websites, and that the overall quality remained problematic. Future research is needed to examine the quality of user-generated content and to explore opportunities offered by emerging new media that can facilitate the consumer evaluation of health information.

    Abstract
    Purpose - The paper seeks to draw on Sice's systems model, itself based on Senge's "fixes that fail" archetype, and on data from two previous research projects conducted by one of the authors. The purpose of this paper is to synthesise a new model that portrays the information-seeking behaviour of children and young people. Design/methodology/approach - The systems model provides the backbone of the new framework but additions, accommodations and revisions were made to ensure that the version featured here represents the phenomenon of information seeking by the young as appropriately as possible in terms of the data that were gathered. Findings - One of the new model's most significant characteristics is its emphasis on problems and issues that prevent information seeking from proceeding smoothly. Information seeking is also shown to be an iterative process, with the individual often revisiting previous stages, frequently in response to difficulties. Research limitations/implications - Data were collected from pupils in just seven schools. The undertaking of research further a-field would be invaluable, if the extent to which the model is applicable to other information-seekers in different environments is to be ascertained. Practical implications - The model demonstrates the importance of the information professional's educative role, in terms of both delivering formal information literacy instruction and providing assistance at the point of need. Originality/value - Although the use of ideas and frameworks from other disciplines, with the aim of increasing understanding of phenomena within LIS, is a growing trend, this paper represents one of the first attempts to apply an existing model associated with systems thinking to information behaviour.
