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

Chaitin, the inventor of algorithmic information theory, presents in this book the strongest possible version of Gödel's incompleteness theorem, using an information theoretic approach based on the size of computer programs. One half of the book is concerned with studying the halting probability of a universal computer if its program is chosen by tossing a coin. The other half is concerned with encoding the halting probability as an algebraic equation in integers, a so-called exponential diophantine equation.

Abstract

Technological changes are occuring rapidly and students entering colleges are bringing very disparate computer skills and attitudes. Some students are reluctant to embrace new technologies, others demand electronic resources for all assignments. By considering the computer access and Internet resources available to elementary school students today, it is possible to imagine what tomorrow's users will expect from libraries. Although college students may arrive at libraries with increased computer skills, their knowledge of electronic information may be lacking. Defines information literacy with an overview of information literacy skills. The Digital Information Literacy programme at Texas University at Austin serves as a case study for integrating information literacy skills into traditional services and partnerships

Abstract

In response to the perceived (by some) onset of an information society, historians have begun to study its roots and antecedents. The past is replete with the rise, fall, and transformation of systems of information, which are not to be confused with the narrower computer-mediated world of information systems. The history of systems of information-which for digestibility can be labeled information history-lacks neither scale nor scope. Systems of information have played a critical role in the transition to, and subsequent development of, capitalism; the growth of the state, especially the modern, nation-state; the rise of modernity, science, and the public sphere; imperialism; and geopolitics. In the context of these epochal shifts and episodes in human thinking and social organization, this essay presents a critical bibliographic survey of histories-outside the well-trodden paths of library and information-science history-that have foregrounded, or made reference to, a wide variety of systems of information.

Rez. in: JASIST 56(2005) no.9, S.1008-1009 (D.E. Agosto): "This second edition of Information Literacy: Essential Skills for the Information Age remains true to the first edition (published in 1998). The main changes involved the updating of educational standards discussed in the text, as well as the updating of the term history. Overall, this book serves as a detailed definition of the concept of information literacy and focuses heavily an presenting and discussing related state and national educational standards and policies. It is divided into 10 chapters, many of which contain examples of U.S. and international information literacy programs in a variety of educational settings. Chapter one offers a detailed definition of information literacy, as well as tracing the deviation of the term. The term was first introduced in 1974 by Paul Zurkowski in a proposal to the national Commission an Libraries and Information Science. Fifteen years later a special ALA committee derived the now generally accepted definition: "To be information literate requires a new set of skills. These include how to locate and use information needed for problem-solving and decision-making efficiently and effectively" (American Library Association, 1989, p. 11). Definitions for a number of related concepts are also offered, including definitions for visual literacy, media literacy, computer literacy, digital literacy, and network literacy. Although the authors do define these different subtypes of information literacy, they sidestep the argument over the definition of the more general term literacy, consequently avoiding the controversy over national and world illiteracy rates. Regardless of the actual rate of U.S. literacy (which varies radically with each different definition of "literacy"), basic literacy, i.e., basic reading and writing skills, still presents a formidable educational goal in the U.S. In fact, More than 5 million high-schoolers do not read well enough to understand their textbooks or other material written for their grade level. According to the National Assessment of Educational Progress, 26% of these students cannot read material many of us world deem essential for daily living, such as road signs, newspapers, and bus schedules. (Hock & Deshler, 2003, p. 27)
Chapter two delves more deeply into the historical evolution of the concept of information literacy, and chapter three summarizes selected information literacy research. Researchers generally agree that information literacy is a process, rather than a set of skills to be learned (despite the unfortunate use of the word "skills" in the ALA definition). Researchers also generally agree that information literacy should be taught across the curriculum, as opposed to limiting it to the library or any other single educational context or discipline. Chapter four discusses economic ties to information literacy, suggesting that countries with information literate populations will better succeed economically in the current and future information-based world economy. A recent report issued by the Basic Education Coalition, an umbrella group of 19 private and nongovernmental development and relief organizations, supports this claim based an meta-analysis of large bodies of data collected by the World Bank, the United Nations, and other international organizations. Teach a Child, Transform a Nation (Basic Education Coalition, 2004) concluded that no modern nation has achieved sustained economic growth without providing near universal basic education for its citizens. It also concluded that countries that improve their literacy rates by 20 to 30% sec subsequent GDP increases of 8 to 16%. In light of the Coalition's finding that one fourth of adults in the world's developing countries are unable to read or write, the goal of worldwide information literacy seems sadly unattainable for the present, a present in which even universal basic literacy is still a pipedream. Chapter live discusses information literacy across the curriculum as an interpretation of national standards. The many examples of school and university information literacy programs, standards, and policies detailed throughout the volume world be very useful to educators and administrators engaging in program planning and review. For example, the authors explain that economics standards included in the Goals 2000: Educate America Act are comprised of 20 benchmark content standards. They quote a two-pronged grade 12 benchmark that first entails students being able to discuss how a high school senior's working 20 hours a week while attending school might result in a reduced overall lifetime income, and second requires students to be able to describe how increasing the federal minimum wage might result in reduced income for some workers. The authors tie this benchmark to information literacy as follows: "Economic decision making requires complex thinking skills because the variables involved are interdependent.
Students need to use the whole range of information literacy skills to identify needed information, evaluate and analyze information, and use information for critical thinking and problem solving" (p. 81). Chapters six and seven address K-12 education and information literacy. The authors outline the restructuring necessary to make information literacy a basic part of the curriculum and emphasize resourcebased learning as crucial in teaching information literacy. The authors also discuss the implications of the 2001 No Child Left Behind Act to the teaching of information literacy in primary and secondary schools. Again they avoid controversy, this time by omitting analysis of the success or failure of the Act in promoting the teaching and learning of information literacy. Instead, these chapters provide a number of examples of information literacy programs in K-12 educational settings within the US. Examples range from information literacy guidelines developed by the California Technology Assistance Project to a discussion of home schoolers and information literacy. Throughout the 1990s, the information literacy movement began to filter up to higher education. Chapter eight discusses related standards and presents a number of examples of college-level information literacy programs, including programs at the University of Massachusetts, Kent State University, and Washington State University. Chapter nine deals with technology and information literacy. It tocuses an the teaching of technology use as process teaching and an the importance of context in technology education.
Lastly, chapter 10 considers possible future directions of the information literacy movement. The authors conclude "Our ability to be information literate depends an our willingness to be lifelong learners as we are challenged to master new, and as yet unknown, technologies that will surely alter the landscape of information in the future" (p. 177). Following the book's 10 chapters are a number of appendices that present information literacy standards and definitions, a timeline of the evolution of the information literacy movement, and a number of related bibliographies. Lead author Eisenberg is perhaps best known as the co-creator, with Bob Berkowitz, of the Big 6, an information literacy model. The model includes six components: Task Definition, Information Seeking Strategies, Location and Access, Use of Information, Synthesis, and Evaluation (Eisenberg, 2003). Throughout the book, Eisenberg and his co-authors show how the Big 6 model can be used to teach information literacy. For example, in chapter nine, "Technology and Information Literacy," they lay out each of the six model components, providing specific technological skills benchmarks for each, such as "Know the roles and computer expertise of the people working in the school library media center and elsewhere who might provide information or assistance" under step 3, "Location and Access" (p. 160). The many detailed descriptions of information literacy policies and programs that appear throughout the book make it most useful for educators, administrators, and policy makers involved in the teaching, planning, and development of information literacy programs, standards, and policies. Overall, this newly revised volume stands as one of the most comprehensive single available sources from which to begin a detailed investigation of the concept of information literacy."

Abstract

A clear line of argument can be set out to link the (passive) intellectual freedom rights offered by Article Nineteen of the United Nations' Universal Declaration on Human Rights, to a consequent responsibility on governments, professionals and civil society activists for the (active) creation of suitable conditions for the effective exercise of intellectual freedom. Commentators on media in society and socially responsible computing are also increasingly drawing conclusions of this kind and stressing the importance of Media Literacy and Computer Literacy. This line of argument naturally directs attention towards the rationale currently offered for Information Literacy as a focus of professional activity. Whilst there are many elaborately worked-out programmes for Information Literacy instruction, these have so far been largely derived from practical perceptions of need. However, broad statements such as the Prague Declaration 'Towards an Information Literate Society' of 2003 and the Alexandria Proclamation of 2005 can be seen as beginning to point towards a rationale for Information Literacy activities rooted in human rights, Article Nineteen in particular. The contention is that starting from a human rights perspective leads towards a strong, inclusive interpretation of Information Literacy. This subsumes Media Literacy, Computer Literacy, Web Literacy and, to a considerable extent, Civic Literacy into a model that serves human needs rather than the established priorities of information professionals. The value of this approach for both practice and research is stressed.

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

Abstract

Navigation is a limited metaphor for hypermedia and website use that potentially constraints our understanding of human-computer interaction. Traces the emergence of the navigation metaphor and the emprical analysis of navigation measures in usability evaluation before suggesting an alternative concept to consider: shape. The shape concept affords a richer analytic tool for considering humans' use of digital documents and invokes social level analysis of meaning that are shared among discourse communities who both produce and consume the information resources

Abstract

Purpose With the shift to an information-based society and to the de-centralisation of information, information overload has attracted a growing interest in the computer and information science research communities. However, there is no clear understanding of the meaning of the term, and while there have been many proposed definitions, there is no consensus. The goal of this work was to define the concept of "information overload". In order to do so, a concept analysis using Rodgers' approach was performed. Design/methodology/approach A concept analysis using Rodgers' approach based on a corpus of documents published between 2010 and September 2020 was conducted. One surrogate for "information overload", which is "cognitive overload" was identified. The corpus of documents consisted of 151 documents for information overload and ten for cognitive overload. All documents were from the fields of computer science and information science, and were retrieved from three databases: Association for Computing Machinery (ACM) Digital Library, SCOPUS and Library and Information Science Abstracts (LISA). Findings The themes identified from the authors' concept analysis allowed us to extract the triggers, manifestations and consequences of information overload. They found triggers related to information characteristics, information need, the working environment, the cognitive abilities of individuals and the information environment. In terms of manifestations, they found that information overload manifests itself both emotionally and cognitively. The consequences of information overload were both internal and external. These findings allowed them to provide a definition of information overload. Originality/value Through the authors' concept analysis, they were able to clarify the components of information overload and provide a definition of the concept.

"In a new article published in Journal of Documentation, 2002, I claim that the special competency of information specialists and information scientists are related to "domain analysis." Information science grew out of special librarianship and documentation (cf. Williams, 1997), and implicit in its tradition has in my opinion been a focus an subject knowledge. Although domain analysis has earlier been introduced in JASIST (Hjoerland & Albrechtsen, 1995), the new article introduces 11 Specific approaches to domain analysis, which I Claim together define the Specific competencies of information specialists. The approaches are (I) Producing and evaluating literature guides and subject gateways, (2) Producing and evaluating special classifications and thesauri, (3) Research an and competencies in indexing and retrieving information specialties, (4) Knowledge about empirical user studies in subject areas, (5) Producing and interpreting bibliometrical studies, (6) Historical studies of information structures and Services in domains, (7) Studies of documents and genres in knowledge domains, (8) Epistemological and critical studies of different paradigms, assumptions, and interests in domains, (9) Knowledge about terminological studies, LSP (Languages for Special Purposes), and discourse analysis in knowledge fields, (10) Knowledge about and studies of structures and institutions in scientific and professional communication in a domain, (11) Knowledge about methods and results from domain analytic studies about professional cognition, knowledge representation in computer science and artificial intelligence. By bringing these approaches together, the paper advocates a view which may have been implicit in previous literature but which has not before been Set out systematically. The approaches presented here are neither exhaustive nor mutually exhaustve, but an attempt is made to present the state of the art. Specific examples and selective reviews of literature are provided, and the strength and drawback of each of these approaches are being discussed. It is my Claim that the information specialist who has worked with these 1 1 approaches in a given domain (e.g., music, sociology, or chemistry) has a special expertise that should not be mixed up with the kind of expertise taught at universities in corresponding subjects. Some of these 11 approaches are today well-known in schools of LIS. Bibliometrics is an example, Other approaches are new and represent a view of what should be introduced in the training of information professionals. First and foremost does the article advocates the view that these 1 1 approaches should be seen as supplementary. That the Professional identity is best maintained if Chose methods are applied to the same examples (same domain). Somebody would perhaps feel that this would make the education of information professionals too narrow. The Counter argument is that you can only understand and use these methods properly in a new domain, if you already have a deep knowledge of the Specific information problems in at least orte domain. It is a dangerous illusion to believe that one becomes more competent to work in any field if orte does not know anything about any domain. The special challenge in our science is to provide general background for use in Specific fields. This is what domain analysis is developed for. Study programs that allow the students to specialize and to work independent in the selected field (such as, for example, the Curriculum at the Royal School of LIS in Denmark) should fit well with the intentions in domain analysis. In this connection it should be emphasized that the 11 approaches are presented as general approaches that may be used in about any domain whatsoever. They should, however, be seen in connection. If this is not the case, then their relative strengths and weaknesses cannot be evaluated. The approaches do not have the same status. Some (e.g., empirical user studies) are dependent an others (e.g., epistemological studies).
It is my hope that domain analysis may contribute to the strengthening of the professional and scientific identity of our discipline and provide more coherence and depth in information studies. The paper is an argument about what should be core teachings in our field, It should be both broad enough to cover the important parts of IS and Specific enough to maintain a special focus and identity compared to, for example, computer science and the cognitive sciences. It is not a narrow view of information science and an the other hand it does not Set forth an unrealistic utopia."

Abstract

This is an empirical, experimental investigation of the value of information, as perceived through the willingness to purchase information (WTP) and the willingness to sell it (accept payment, WTA). We examined the effects of source nature: expertise versus content, and source status: copy versus exclusive original of information on the WTA-WTP ratio. In an animated computer simulation of a business game, players could maximize their profits by making choices regarding inventory and prices. Participants were offered the chance to bid for buying or selling information regarding the weather that may affect demand. We find, as hypothesized, that the subjective value of information does indeed follow the predictions of endowment effect theory. The ratio of willingness to accept to willingness to purchase (WTA-WTP) recorded for the 294 subjects resembles the ratio common for private goods, rather than the intuitively expected unity. The WTA-WTP ratios diverged from unity more often and in a more pronounced manner for information traded in the original form rather than as a copy of the original, although even for copies the WTA-WTP ratio is still double. The results yield a value of about three for the WTA-WTP ratio for original information whether the source is content or expertise. Copy information received a subjective value that was significantly different (lower) than original information. The implications for both online trading and online sharing of information are discussed.

Abstract

This review introduces a comprehensive model of the cognitive process and mechanisms of individual sensemaking to provide a theoretical basis for: - empirical studies that improve our understanding of the cognitive process and mechanisms of sensemaking and integration of results of such studies; - education in critical thinking and sensemaking skills; - the design of sensemaking assistant tools that support and guide users. The paper reviews and extends existing sensemaking models with ideas from learning and cognition. It reviews literature on sensemaking models in human-computer interaction (HCI), cognitive system engineering, organizational communication, and library and information sciences (LIS), learning theories, cognitive psychology, and task-based information seeking. The model resulting from this synthesis moves to a stronger basis for explaining sensemaking behaviors and conceptual changes. The model illustrates the iterative processes of sensemaking, extends existing models that focus on activities by integrating cognitive mechanisms and the creation of instantiated structure elements of knowledge, and different types of conceptual change to show a complete picture of the cognitive processes of sensemaking. The processes and cognitive mechanisms identified provide better foundations for knowledge creation, organization, and sharing practices and a stronger basis for design of sensemaking assistant systems and tools.

Abstract

Controversies in modern ideas in social work directly reflect controversies in attitudes toward computer applications. Fundamental to modern problems with technology is the persisting dispute between 2 philosophical traditions. On one side there is the formal and technically oriented thinking: on the other the reflexive, dialectical and hermeneutical approach. The reappearance of the conflict in actual discussion is described considering data storage, formal methodology and the social impact of computer use
