Abstract

The Turn analyzes the research of information seeking and retrieval (IS&R) and proposes a new direction of integrating research in these two areas: the fields should turn off their separate and narrow paths and construct a new avenue of research. An essential direction for this avenue is context as given in the subtitle Integration of Information Seeking and Retrieval in Context. Other essential themes in the book include: IS&R research models, frameworks and theories; search and works tasks and situations in context; interaction between humans and machines; information acquisition, relevance and information use; research design and methodology based on a structured set of explicit variables - all set into the holistic cognitive approach. The present monograph invites the reader into a construction project - there is much research to do for a contextual understanding of IS&R. The Turn represents a wide-ranging perspective of IS&R by providing a novel unique research framework, covering both individual and social aspects of information behavior, including the generation, searching, retrieval and use of information. Regarding traditional laboratory information retrieval research, the monograph proposes the extension of research toward actors, search and work tasks, IR interaction and utility of information. Regarding traditional information seeking research, it proposes the extension toward information access technology and work task contexts. The Turn is the first synthesis of research in the broad area of IS&R ranging from systems oriented laboratory IR research to social science oriented information seeking studies.

Rez. in: Mitt. VÖB 59(2006) H.2, S.81-83 (O. Oberhauser): "Mit diesem Band haben zwei herausragende Vertreter der europäischen Informationswissenschaft, die Professoren Peter Ingwersen (Kopenhagen) und Kalervo Järvelin (Tampere) ein Werk vorgelegt, das man vielleicht dereinst als ihr opus magnum bezeichnen wird. Mich würde dies nicht überraschen, denn die Autoren unternehmen hier den ambitionierten Versuch, zwei informations wissenschaftliche Forschungstraditionen, die einander bisher in eher geringem Ausmass begegneten, unter einem gesamtheitlichen kognitiven Ansatz zu vereinen - das primär im sozialwissenschaftlichen Bereich verankerte Forschungsgebiet "Information Seeking and Retrieval" (IS&R) und das vorwiegend im Informatikbereich angesiedelte "Information Retrieval" (IR). Dabei geht es ihnen auch darum, den seit etlichen Jahren zwar dominierenden, aber auch als zu individualistisch kritisierten kognitiven Ansatz so zu erweitern, dass technologische, verhaltensbezogene und kooperative Aspekte in kohärenter Weise berücksichtigt werden. Dies geschieht auf folgende Weise in neun Kapiteln: - Zunächst werden die beiden "Lager" - die an Systemen und Laborexperimenten orientierte IR-Tradition und die an Benutzerfragen orientierte IS&R-Fraktion - einander gegenübergestellt und einige zentrale Begriffe geklärt. - Im zweiten Kapitel erfolgt eine ausführliche Darstellung der kognitiven Richtung der Informationswissenschaft, insbesondere hinsichtlich des Informationsbegriffes. - Daran schliesst sich ein Überblick über die bisherige Forschung zu "Information Seeking" (IS) - eine äusserst brauchbare Einführung in die Forschungsfragen und Modelle, die Forschungsmethodik sowie die in diesem Bereich offenen Fragen, z.B. die aufgrund der einseitigen Ausrichtung des Blickwinkels auf den Benutzer mangelnde Betrachtung der Benutzer-System-Interaktion. - In analoger Weise wird im vierten Kapitel die systemorientierte IRForschung in einem konzentrierten Überblick vorgestellt, in dem es sowohl um das "Labormodell" als auch Ansätze wie die Verarbeitung natürlicher Sprache und Expertensysteme geht. Aspekte wie Relevanz, Anfragemodifikation und Performanzmessung werden ebenso angesprochen wie die Methodik - von den ersten Laborexperimenten bis zu TREC und darüber hinaus.
- Kapitel fünf enthält einen entsprechenden Überblick über die kognitive und benutzerorientierte IR-Tradition. Es zeigt, welche anderen (als nur die labororientierten) IR-Studien durchgeführt werden können, wobei sich die Betrachtung von frühen Modellen (z.B. Taylor) über Belkins ASK-Konzept bis zu Ingwersens Modell der Polyrepräsentation, und von Bates Berrypicking-Ansatz bis zu Vakkaris "taskbased" IR-Modell erstreckt. Auch Web-IR, OKAPI und Diskussionen zum Relevanzbegriff werden hier thematisiert. - Im folgenden Kapitel schlagen die Autoren ein integriertes IS&R Forschungsmodell vor, bei dem die vielfältigen Beziehungen zwischen Informationssuchenden, Systementwicklern, Oberflächen und anderen beteiligten Aspekten berücksichtigt werden. Ihr Ansatz vereint die traditionelle Laborforschung mit verschiedenen benutzerorientierten Traditionen aus IS&R, insbesondere mit den empirischen Ansätzen zu IS und zum interaktiven IR, in einem holistischen kognitiven Modell. - Kapitel sieben untersucht die Implikationen dieses Modells für IS&R, wobei besonders ins Auge fällt, wie komplex die Anfragen von Informationssuchenden im Vergleich mit der relativen Einfachheit der Algorithmen zum Auffinden relevanter Dokumente sind. Die Abbildung der vielfältig variierenden kognitiven Zustände der Anfragesteller im Rahmen der der Systementwicklung ist sicherlich keine triviale Aufgabe. Wie dabei das Problem der Einbeziehung des zentralen Aspektes der Bedeutung gelöst werden kann, sei dahingestellt. - Im achten Kapitel wird der Versuch unternommen, die zuvor diskutierten Punkte in ein IS&R-Forschungsprogramm (Prozesse - Verhalten - Systemfunktionalität - Performanz) umzusetzen, wobei auch einige kritische Anmerkungen zur bisherigen Forschungspraxis getroffen werden. - Das abschliessende neunte Kapitel fasst das Buch kurz zusammen und kann somit auch als Einstieg in dieThematik gelesen werden. Darauffolgen noch ein sehr nützliches Glossar zu allen wichtigen Begriffen, die in dem Buch Verwendung finden, eine Bibliographie und ein Sachregister. Ingwersen und Järvelin haben hier ein sehr anspruchsvolles und dennoch lesbares Buch vorgelegt. Die gebotenen Übersichtskapitel und Diskussionen sind zwar keine Einführung in die Informationswissenschaft, decken aber einen grossen Teil der heute in dieser Disziplin aktuellen und durch laufende Forschungsaktivitäten und Publikationen berührten Teilbereiche ab. Man könnte es auch - vielleicht ein wenig überspitzt - so formulieren: Was hier thematisiert wird, ist eigentlich die moderne Informationswissenschaft. Der Versuch, die beiden Forschungstraditionen zu vereinen, wird diesem Werk sicherlich einen Platz in der Geschichte der Disziplin sichern. Nicht ganz glücklich erscheint der Titel des Buches. "The Turn" soll eine Wende bedeuten, nämlich jene hin zu einer integrierten Sicht von IS und IR. Das geht vermutlich aus dem Untertitel besser hervor, doch dieser erschien den Autoren wohl zu trocken. Schade, denn "The Turn" gibt es z.B. in unserem Verbundkatalog bereits, allerdings mit dem Zusatz "from the Cold War to a new era; the United States and the Soviet Union 1983-1990". Der Verlag, der abgesehen davon ein gediegenes (wenn auch nicht gerade wohlfeiles) Produkt vorgelegt hat, hätte derlei unscharfe Duplizierend besser verhindert. Ungeachtet dessen empfehle ich dieses wichtige Buch ohne Vorbehalt zur Anschaffung; es sollte in keiner grösseren Bibliothek fehlen."

Abstract

Although much of the hubris and hyperbole surrounding the 1990's Internet has softened to a reasonable level, the inexorable momentum of information growth continues unabated. This wealth of information provides resources for adapting to the problems posed by our increasingly complex world, but the simple availability of more information does not guarantee its successful transformation into valuable knowledge that shapes, guides, and improves our activity. When faced with something like the analysis of sense-making behavior on the web, traditional research models tell us a lot about learning and performance with browser operations, but very little about how people will actively navigate and search through information structures, what information they will choose to consume, and what conceptual models they will induce about the landscape of cyberspace. Thus, it is fortunate that a new field of research, Adaptive Information Interaction (AII), is becoming possible. AII centers on the problems of understanding and improving human-information interaction. It is about how people will best shape themselves to their information environments, and how information environments can best be shaped to people. Its roots lie in human-computer interaction (HCI), information retrieval, and the behavioral and social sciences. This book is about Information Foraging Theory (IFT), a new theory in Adaptive Information Interaction that is one example of a recent flourish of theories in adaptationist psychology that draw upon evolutionary-ecological theory in biology. IFT assumes that people (indeed, all organisms) are ecologically rational, and that human information-seeking mechanisms and strategies adapt the structure of the information environments in which they operate. Its main aim is to create technology that is better shaped to users. Information Foraging Theory will be of interest to student and professional researchers in HCI and cognitive psychology.

Abstract

Information Science (IS) is commonly said to study collection, classification, storage, retrieval, and use of information. However, there is no consensus on what information is. This article examines some of the formal models of information and informational processes, namely, Situation Theory and Shannon's Information Theory, in terms of their suitability for providing a useful framework for studying information in IS. It is argued that formal models of information are concerned with mainly ontological aspects of information, whereas IS, because of its evaluative role with respect to semantic content, needs an epistemological conception of information. It is argued from this perspective that concepts of epistemological/aesthetic/ethical information are plausible, and that information science needs to rise to the challenge of studying many different conceptions of information embedded in different contexts. This goal requires exploration of a wide variety of tools from philosophy and logic.

Rez. in: Information Research, 9(3), review no. R129 (T.D. Wilson): "The first edition of this book was published ten years ago and rapidly become something of a classic in the field of information seeking behaviour. It is good to see the second edition which incorporates not only the work the author has done since 1993, but also related work by other researchers. Kuhlthau is one of the most cited authors in the field and her model of the information search process, involving stages in the search and associated feelings, has been used by others in a variety of contexts. However, what makes this book different (as was the case with the first edition) is the author's dedication to the field of practice and the book's sub-title demonstrates her commitment to the transfer of research. In Kuhlthau's case this is the practice of the school library media specialist, but her research has covered students of various ages as well as a wide range of occupational groups. Because the information search model is so well known, I shall concentrate in this review on the relationship between the research findings and practice. It is necessary, however, to begin with the search process model, because this is central. Briefly, the model proposes that the searcher goes through the stages of initiation, selection, exploration, formulation, collection and presentation, and, at each stage, experiences various feelings ranging from optimism and satisfaction to confusion and disappointment. Personally, I occasionally suffer despair, but perhaps that is too extreme for most!
It is important to understand the origins of Kuhlthau's ideas in the work of the educational theorists, Dewey, Kelly and Bruner. Putting the matter in a rather simplistic manner, Dewey identified stages of cognition, Kelly attached the idea of feelings being associated with cognitive stages, and Bruner added the notion of actions associated with both. We can see this framework underlying Kuhlthau's research in her description of the actions undertaken at different stages in the search process and the associated feelings. Central to the transfer of these ideas to practice is the notion of the 'Zone of Intervention' or the point at which an information seeker can proceed more effectively with assistance than without. Kuhlthau identifies five intervention zones, the first of which involves intervention by the information seeker him/herself. The remaining four involve interventions of different kinds, which the author distinguishes according to the level of mediation required: zone 2 involves the librarian as 'locater', i.e., providing the quick reference response; zone 3, as 'identifier', i.e., discovering potentially useful information resources, but taking no further interest in the user; zone 4 as 'advisor', i.e., not only identifying possibly helpful resources, but guiding the user through them, and zone 5 as 'counsellor', which might be seen as a more intensive version of the advisor, guiding not simply on the sources, but also on the overall process, through a continuing interaction with the user. Clearly, these processes can be used in workshops, conference presentations and the classroom to sensitise the practioner and the student to the range of helping strategies that ought to be made available to the information seeker. However, the author goes further, identifying a further set of strategies for intervening in the search process, which she describes as 'collaborating', 'continuing', 'choosing', 'charting', 'conversing' and 'composing'. 'Collaboration' clearly involves the participation of others - fellow students, work peers, fellow researchers, or whatever, in the search process; 'continuing' intervention is associated with information seeking that involves a succession of actions - the intermediary 'stays with' the searcher throughout the process, available as needed to support him/her; 'choosing', that is, enabling the information seeker to identify the available choices in any given situation; 'charting' involves presenting a graphic illustration of the overall process and locating the information seeker in that chart; 'conversing' is the encouragement of discussion about the problem(s), and 'composing' involves the librarian as counsellor in encouraging the information seeker to document his/her experience, perhaps by keeping a diary of the process.
Together with the zones of intervention, these ideas, and others set out in the book, provide a very powerful didactic mechanism for improving library and information service delivery. Of course, other things are necessary - the motivation to work in this way, and the availability resources to enable its accomplishment. Sadly, at least in the UK, many libraries today are too financially pressed to do much more than the minimum helpful intervention in the information seeking process. However, that should not serve as a stick with which to beat the author: not only has she performed work of genuine significance in the field of human information behaviour, she has demonstrated beyond question that the ideas that have emerged from her research have the capability to help to deliver more effective services."

Abstract

With the proliferation of new information channels such as the Web, e-mail and wireless, it is becoming increasingly important to understand the impact of these technologies within information-seeking and retrieval contexts. This issue of Aslib Proceedings presents research that begins to address the notion of "information disparity". It aims to weave a common thread between the challenges of reconciling disparate information needs in an environment complicated by fragmented or disparate data sources. This article lists several emerging trends that should begin to challenge traditional notions of our research field.

Abstract

This book explores two main models of Information Literacy or IL: the SCONUL (Society of College, National and University Libraries) Seven Pillars of Information Skills and the IL competencies identified by the ALA (American Library Association). Practical examples for the development of IL skills identified by these models are illustrated using printed and web-based resources. The process of integrating IL provision within a programme of study is outlined to illustrate two strategies underpinning this integration at generic-skills level, the 'plug & play' approach, and at subject-specific level, the 'research skills approach'. A range of diagnostic and assessment methods, to monitor the iterative process of IL skills development, are also included.

Rez. in: Mitteilungen VOEB 59(2006) H.4, S.74-76 (M. Katzmayr): "Information Literacy (IL) bzw. Informationskompetenz ist in aller Munde, wird sie doch als Schlüsselqualifikation angesehen, um an der so genannten Informationsgesellschaft teilzuhaben. Susie Andretta, Dozentin für Informationsmanagement an der London Metropolitan University, hat nun einen praxisorientierten Leitfaden zur IL vorgelegt, worin zwei Aspekte im Vordergrund stehen: einerseits die Vermittlung der IL in der universitären Lehre, womit andererseits auch ein erfolgreiches lebenslanges Lernen nach Verlassen der Universität ermöglicht werden soll. Das Buch beginnt mit einer theoretischen Einführung. Dort ist zu lesen, dass sich die Vermittlung von IL aus Kursen zur Bibliotheksbenutzung entwickelt habe - doch während letztere traditionell den effektiven Umgang mit Bibliotheksressourcen vermitteln und somit auf die Bibliothek beschränkt seien, beinhalte IL auch Herangehensweisen zur Lösung komplexer Problemstellungen. Drei prominente IL-Konzeptionen folgender Organisationen werden anschließend ausführlicher vorgestellt und verglichen: die der US-amerikanischen "Association of Colleges and Research Libraries" (ACRL), des "Australian and New Zealand Institute for information Literacy" (ANZIIL) und der britischen "Society of College, National and University Libraries" (SCONUL). In allen drei besteht IL zumindest aus dem Wahrnehmen eines Informationsbedarfes, Methoden zum Erhalt dieser Information und schließlich ihrer Bewertung, um die Fragen zu beantworten, die zum Informationsbedarf geführt haben. Alle drei gehen über die rein technologische Kompetenz (IT-Kompetenz) hinaus und umfassen u. a. Medien-, Bibliotheks-, und Recherchekompetenzen, um nur einige zu nennen. Allerdings gehen zwei dieser Konzeptionen noch wesentlich weiter - so fordert die ANZIIL von einer informationskompetenten Person u.a. folgende Fähigkeit: "the information-literate person applies prior and new information to construct new concepts or create new understandings" (S. 157), der Lernzielkatalog der SCONUL beinhaltet: "The ability to synthesise and build upon existing information, contributing to the creation of new knowledge" (S. 162).
Was hier auffällt, ist der äußerst weit reichende inhaltliche Anspruch dieser Sichtweise von IL. Inwieweit dadurch eine Abgrenzung zum Themenund Lehrgebiet des "wissenschaftlichen Arbeitens" bzw. zu den Charakteristika umfassender Bildung überhaupt noch sinnvoll möglich ist, wird von der Autorin leider nicht behandelt. Interessant ist der Stellenwert der Bibliotheken in der Lehre der IL: In allen drei Konzeptionen wird eine Kooperation zwischen Bibliothek und Wissenschaftsbetrieb empfohlen, ja erfolge die Vermittlung von IL idealiter im jeweiligen Fachstudium durch die problemlösungsorientierte Bearbeitung spezifischer Fragestellungen. So gesehen könne also nicht von einem Monopol der Bibliotheken ausgegangen werden, ihre Rolle sei vielmehr mit dem Motto "information literacy is an issue for the library but not of the library" (S. 53) angemessen umschrieben. In Großbritannien gehe dabei die Initiative meist von den Bibliotheken aus, in den USA und Australien eher vom Wissenschaftsbetrieb. In beiden Fällen funktioniere diese Partnerschaft aber nicht immer reibungslos. Die Beweggründe von Bibliotheken, sich hierzu engagieren, werden von der Autorin jedoch keiner tiefer gehenden Analyse unterzogen. Dies wurde vielleicht nicht völlig unbeabsichtigt unterlassen, da daran nämlich eine - im vorliegenden Werk ausgeblendete - grundsätzliche und weit verbreitete Kritik an der IL anknüpfen könnte. Ein Blick in die relevante Literatur zeigt nämlich, dass Bibliothekarinnen nicht nur hehre Motive zugeschrieben werden, wenn sie sich am IL-Hype beteiligen bzw. ihn vorantreiben. Neben Erfahrungen mit der dürftigen Informationskompetenz vieler Studierender werden ihnen auch ganz andere, pragmatischere Beweggründe zugedacht'. Ein Beispiel: Die zunehmende institutionelle Marginalisierung von Bibliotheken und ihren Mitarbeiterinnen im Universitätsbetrieb mag eine kreative Vorwärtsverteidigung unter dem Deckmantel der IL als zweckmäßig erscheinen lassen' - überspitzt formuliert: IL als Konstrukt oder zumindest willkommene Gelegenheit, um den Bibliotheken auch weiterhin eine zentrale Rolle an den Universitäten zu sichern. Zum Glück gelingt es Andretta, anhand der relevanten Literatur und eigener Erfahrungen als Dozentin plausibel zu argumentieren, dass der Mangel vieler Studierender an Informationskompetenz tatsächlich eklatant und somit ein Handlungsbedarf gegeben ist. Welche Motive die Bibliotheken hier sonst noch haben mögen, kann so gesehen ruhig im Dunkeln bleiben.

Abstract

In the Web, making judgments of information quality and authority is a difficult task for most users because overall, there is no quality control mechanism. This study examines the problem of the judgment of information quality and cognitive authority by observing people's searching behavior in the Web. Its purpose is to understand the various factors that influence people's judgment of quality and authority in the Web, and the effects of those judgments on selection behaviors. Fifteen scholars from diverse disciplines participated, and data were collected combining verbal protocols during the searches, search logs, and postsearch interviews. It was found that the subjects made two distinct kinds of judgment: predictive judgment, and evaluative judgment. The factors influencing each judgment of quality and authority were identified in terms of characteristics of information objects, characteristics of sources, knowledge, situation, ranking in search output, and general assumption. Implications for Web design that will effectively support people's judgments of quality and authority are also discussed

Abstract

Introduction. This short paper proposes that a unified concept of information as a form of self-organized complexity may be equally applicable to the physical, biological and human/social domains. This is seen as the evolutionary emergence of organized complexity in the physical universe, meaning in context in the biological domain, and understanding through knowledge in the human domain. Method.This study is based on analysis of literature from a wide range of disciplines. Conclusions.This perspective allows for the possibility that not only may the library/information sciences be able to draw insights from the natural sciences, but that library and information science research and scholarship may in turn contribute insights to these disciplines, normally thought of as more 'fundamental'.

Abstract

With the rapidly changing Web-enabled world, the already existing dichotomy between knowing of and knowing about, or information naïveté, widens daily. This article explores the ethical dilemmas that can result from the lack of information literacy. The article also discusses conditions and consequences of information naïveté, media bias, possessive memory, and limited contexts and abilities. To help avoid information failure, the author recommends producers, contributors, disseminators, and aggregators of information be less information naïve.

Abstract

This report explores the intellectual processes entailed during information seeking, as information needs are generated and information is sought and evaluated for relevance. It focuses an the details of cognitive processing, reviewing a number of models. In particular, Popper's model of the communication process between an individual and new information is explored and elaborated from the perspective of Pask's Conversation Theory. The implications of this theory are discussed in relation to the development of what Cole has termed "enabling" information retrieval systems.

Abstract

How can one verify the accuracy of recorded information (e.g., information found in books, newspapers, and on Web sites)? In this paper, I argue that work in the epistemology of testimony (especially that of philosophers David Hume and Alvin Goldman) can help with this important practical problem in library and information science. This work suggests that there are four important areas to consider when verifying the accuracy of information: (i) authority, (ii) independent corroboration, (iii) plausibility and support, and (iv) presentation. I show how philosophical research in these areas can improve how information professionals go about teaching people how to evaluate information. Finally, I discuss several further techniques that information professionals can and should use to make it easier for people to verify the accuracy of information.

Abstract

This article presents a socio-cognitive perspective in relation to information science (IS) and information retrieval (IR). The differences between traditional cognitive views and the socio-cognitive or domain-analytic view are outlined. It is claimed that, given elementary skills in computer-based retrieval, people are basically interacting with representations of subject literatures in IR. The kind of knowledge needed to interact with representations of subject literatures is discussed. It is shown how different approaches or "paradigms" in the represented literature imply different information needs and relevance criteria (which users typically cannot express very well, which is why IS cannot primarily rely on user studies). These principles are exemplified by comparing behaviorism, cognitivism, psychoanalysis, and neuroscience as approaches in psychology. The relevance criteria implicit in each position are outlined, and empirical data are provided to prove the theoretical claims. It is further shown that the most general level of relevance criteria is implied by epistemological theories. The article concludes that the fundamental problems of IS and IR are based in epistemology, which therefore becomes the most important allied field for IS.

Abstract

Purpose - The purpose of this paper is to analyse the extent to which understanding information science (IS) and information retrieval (IR) as disciplines characterised by intractable dilemmas is a useful conceptual framework through reviewing and re-evaluating an important contribution to the field in light of more recent developments. Design/methodology/approach - This paper reviews the discussion of central dilemmas within IS and IR, through literature review and conceptual analysis. It assesses the extent to which they remain intractable problems or whether improved solutions have been developed and discusses the implications of these ongoing challenges. The main problem addressed is, in Neill's terminology, "the dilemma of the subjective in information organisation and retrieval" which is understood as the problem of how the meaning of documents can be represented to meet the needs of the user. Findings - Many of the dilemmas discussed within IS and IR remain fairly intractable primarily because information and meaning have both subjective and objective qualities which often have a complex relationship. Recent technological developments have, however, altered the nature of some of these dilemmas and also created some new dilemmas for the subject. Research implications/limitations - Historical perspectives within IR and IS should be used when discussing theoretical and technological developments in the subject. The conceptual framework of dilemmas remains a useful theoretical tool for IS and IR in terms of examining the nature of problems in research and practice. Originality/value - This paper re-visits an important theme in IS and IR and provides an updated perspective on some central issues.

Abstract

Fundamental forms of information, as well as the term information itself, are defined and developed for the purposes of information science/studies. Concepts of natural and represented information (taking an unconventional sense of representation), encoded and embodied information, as well as experienced, enacted, expressed, embedded, recorded, and trace information are elaborated. The utility of these terms for the discipline is illustrated with examples from the study of information-seeking behavior and of information genres. Distinctions between the information and curatorial sciences with respect to their social (and informational) objects of study are briefly outlined.

Abstract

This paper suggests a framework and systematic definitions for 6 words commonly used in dthe field of information science: data, information, knowledge, wisdom, inspiration, and intelligence. We intend these definitions to lead to a quantification of information science, a quantification that will enable their measurement, manipulastion, and prediction.

Abstract

With new interactive technology, we can increase user satisfaction by designing information retrieval systems that inform the user while the user is on-line interacting with the system. The purpose of this article is to model the information processing operations of a generic user who has just received an information message from the system and is stimulated by the message into grasping at a higher understanding of his or her information task or problem. The model consists of 3 levels, each of which forms a separate subsystem. In the Perseption subsystem, the user perceives the system message in a visual sense; in the Comprehension subsystem, the user must comprehend the system message; and in the Application subsystem, the user must (a) interpret the system message in terms of the user's task at hand, and (b) create and send a new message back to the system to complete the interaction. Because of the information process stimulated by the interaction, the user's new message forms a query to the system that more accurately represents the user's information need than would have been the case if the interaction had not taken place. This article proposes a device to enable clarification of the user's task, and thus his/her information need at the Application subsystem level of the model

Abstract

This article reviews selected literature related to the credibility of information, including (1) the general markers of credibility, and how different source, message and receiver characteristics affect people's perceptions of information; (2) the impact of information medium on the assessment of credibility; and (3) the assessment of credibility in the context of information presented on the Internet. The objective of the literature review is to synthesize the current state of knowledge in this area, develop new ways to think about how people interact with information presented via the Internet, and suggest next steps for research and practical applications. The review examines empirical evidence, key reviews, and descriptive material related to credibility in general, and in terms of on-line media. A general discussion of credibility and persuasion and a description of recent work on the credibility and persuasiveness of computer-based applications is presented. Finally, the article synthesizes what we have learned from various fields, and proposes a model as a framework for much-needed future research in this area
