Abstract

The central problem with understanding brain and mind is the neural code issue: understanding the matter of our brain as basis for the phenomena of our mind. The richness with which our mind represents our environment, the parsimony of genetic data, the tremendous efficiency with which the brain learns from scant sensory input and the creativity with which our mind constructs mental worlds all speak in favor of mind as an emergent phenomenon. This raises the further issue of how the neural code supports these processes of organization. The central point of this communication is that the neural code has the form of structured net fragments that are formed by network self-organization, activate and de-activate on the functional time scale, and spontaneously combine to form larger nets with the same basic structure.

Abstract

Since 2004, the authors have designed a proposal of paradigms for the Documentation-Information field, which starts from a comprehensive meaning of the concept and is based on identifying the presence of a custodial, cultural, historicist- and-humanist, and technicist paradigm that has shaped the professional activity, education, and public policies of the archival, librarian, and museologist universe from the early 1800s to the mid-20th century. It also includes pointin out the emergence of a new post-custodial, informational, and scientific paradigm, generated by the profound changes taking place worldwide and that are summarized in strong, yet too generic, expressions such as "information era" or "globalization." This paper characterizes the two paradigms proposed, highlighting their dominant traits and showing their operational relevance at the level of education, research, and professional practice.

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

The first aim is to provide well-articulated concepts by thinking through elementary phenomena of today's world, focusing on privacy and the digital, to clarify who we are in the cyberworld - hence a phenomenology of digital whoness. The second aim is to engage critically, hermeneutically with older and current literature on privacy, including in today's emerging cyberworld. Phenomenological results include concepts of i) self-identity through interplay with the world, ii) personal privacy in contradistinction to the privacy of private property, iii) the cyberworld as an artificial, digital dimension in order to discuss iv) what freedom in the cyberworld can mean, whilst not neglecting v) intercultural aspects and vi) the EU context.

Abstract

To oversimplify, science has two fundamental ways of changing our understanding. One may be called extrovert, or about the world, and the other introvert, or about ourselves. Three scientific revolutions in the past had great impact both extrovertly and introvertly. In changing our understanding of the external world, they also modified our conception of who we are, that is, our self-understanding. The story is well known, so I shall recount it rather quickly. We used to think that we were at the centre of the universe, nicely placed there by a creator God. It was a most comfortable and reassuring position to hold. In 1543, Nicolaus Copernicus published his treatise on the movements of planets around the sun. It was entitled On the Revolutions of Celestial Bodies (De Revolutionibus Orbium Coelestium). Copernicus probably did not mean to start a 'revolution' in our self-understanding as well. Nonetheless, his heliocentric cosmology forever displaced the earth from the centre of the universe and made us reconsider, quite literally, our own place and role in it. It caused such a profound change in our views of the universe that the word 'revolution' begun to be associated with radical scientific transformation. We have been dealing with the consequences of the Copernican revolution since its occurrence. Indeed, it is often remarked that one of the significant achievements of our space explorations has been a matter of external and comprehensive reflection on our human condition.

Abstract

The semiotics of C. S. Peirce presents fundamental concepts to discover aspects of the indexing process, including representation and classes of signs. However, we still know little of its theoretical potential for subject indexing. We believe that the main difficulty in the proposals to understand the process of subject indexing based on Peircean semiotics stems from an incomplete interpretation of his semiotic system. This paper attempts to describe the contributions of Peircean semiotics to subject indexing. First, we analyze some of the concepts of the branches of semiotics, after which, we discuss strategies for conceptual approximation. Secondly, and aiming to raise the level of interlocution between the areas, we intend to argue that subject indexing is an inferential process, as explained by the second branch of semiotics. Thus, we seek to go beyond the level of speculative grammar, the first branch of semiotics, to forge a closer link with pure or critical logic, the second branch. We conclude that the indexer's work does not produce a mere reflection of what already exists in documents, but involves an instigating action to discover, through the inferential matrix, the meaning of a text in order to find the subject and the most a ppropriate subject added entry to the information system.

Abstract

This article presents an updated account of integrated information theory of consciousness (IIT) and some of its implications. IIT stems from thought experiments that lead to phenomenological axioms (existence, compositionality, information, integration, exclusion) and corresponding ontological postulates. The information axiom asserts that every experience is specific - it is what it is by differing in its particular way from a large repertoire of alternatives. The integration axiom asserts that each experience is unified - it cannot be reduced to independent components. The exclusion axiom asserts that every experience is definite - it is limited to particular things and not others and flows at a particular speed and resolution. IIT formalizes these intuitions with postulates. The information postulate states that only "differences that make a difference" from the intrinsic perspective of a system matter: a mechanism generates cause-effect information if its present state has selective past causes and selective future effects within a system. The integration postulate states that only information that is irreducible matters: mechanisms generate integrated information only to the extent that the information they generate cannot be partitioned into that generated within independent components. The exclusion postulate states that only maxima of integrated information matter: a mechanism specifies only one maximally irreducible set of past causes and future effects - a concept. A complex is a set of elements specifying a maximally irreducible constellation of concepts, where the maximum is evaluated over elements and at the optimal spatio-temporal scale. Its concepts specify a maximally integrated conceptual information structure or quale, which is identical with an experience. Finally, changes in information integration upon exposure to the environment reflect a system's ability to match the causal structure of the world. After introducing an updated definition of information integration and related quantities, the article presents some theoretical considerations about the relationship between information and causation and about the relational structure of concepts within a quale. It also explores the relationship between the temporal grain size of information integration and the dynamic of metastable states in the corticothalamic complex. Finally, it summarizes how IIT accounts for empirical findings about the neural substrate of consciousness, and how various aspects of phenomenology may in principle be addressed in terms of the geometry of information integration.

Abstract

This article considers the relationships among meaning generation, selection, and the dynamics of discourse from a variety of perspectives ranging from information theory and biology to sociology. Following Husserl's idea of a horizon of meanings in intersubjective communication, we propose a way in which, using Shannon's equations, the generation and selection of meanings from a horizon of possibilities can be considered probabilistically. The information-theoretical dynamics we articulate considers a process of meaning generation within cultural evolution: information is imbued with meaning, and through this process, the number of options for the selection of meaning in discourse proliferates. The redundancy of possible meanings contributes to a codification of expectations within the discourse. Unlike hardwired DNA, the codes of nonbiological systems can coevolve with the variations. Spanning horizons of meaning, the codes structure the communications as selection environments that shape discourses. Discursive knowledge can be considered as meta-coded communication that enables us to translate among differently coded communications. The dynamics of discursive knowledge production can thus infuse the historical dynamics with a cultural evolution by adding options, that is, by increasing redundancy. A calculus of redundancy is presented as an indicator whereby these dynamics of discourse and meaning may be explored empirically.

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

How does information lead to changes in human behavior? Why have current information theories been inadequate to shed light on this and related questions? Library and Information Science (LIS) has arrived at a crucial juncture in its relatively brief theoretical history. In addition to the cognitive and physical perspectives in our study of information, a new paradigm has been suggested; the affective paradigm. This new perspective offers keys to unlocking questions about the nature of the interaction of human and information. In recent years we have developed deeper knowledge and deeper specializations, drawing together and combining knowledge from multiple fields in order to advance our own knowledge. The relationship between information needs and information seeking has been well studied. The ways in which people use information is not as well understood because of the complex nature of human behavior. Drawing from other fields that study human behavior, however, muddies the traditional boundaries of LIS, creating some possible discomfort as we trespass into lesser known intellectual territory. Pushing our boundaries also forces questions of our self-identity as a discipline. What constitutes Library and Information Science, either in whole or in part, becomes more difficult to define and can lead to greater fragmentation. Alternatively, the incorporation of multiple perspectives may be the defining core of what constitutes LIS. The focus of this talk is to look at LIS from the outside in, from a multidisciplinary perspective, in order to shed light on questions of how information can lead to changes in human behavior. Drawing from other fields of study, the impact of information on human behavior will be explored in light of what other fields may have to offer.

Abstract

Purpose In contrast to the interest of describing and managing the social processes of knowing, information science and information and knowledge management research have put less emphasis on discussing how particular information becomes usable and how it is used in different contexts and situations. The purpose of this paper is to address this major gap, and introduce and discuss the applicability of the notion of situational appropriation of information for shedding light on this particular process in the context of daily information work practices of professionals. Design/methodology/approach The study is based on the analysis of 25 qualitative interviews of archives, library and museum professionals conducted in two Nordic countries. Findings The study presents examples of how individuals appropriate different tangible and intangible assets as information on the basis of the situation in hand. Research limitations/implications The study proposes a new conceptual tool for articulating and conducting research on the process how information becomes useful in the situation in hand. Practical implications The situational appropriation of information perspective redefines the role of information management to incorporate a comprehensive awareness of the situations when information is useful and is being used. A better understanding how information becomes useful in diverse situations helps to discern the active role of contextual and situational effects and to exploit and take them into account as a part of the management of information and knowledge processes. Originality/value In contrast to orthodoxies of information science and information and knowledge management research, the notion of situational appropriation of information represents an alternative approach to the conceptualisation of information utilisation. It helps to frame particular types of instances of information use that are not necessarily addressed within the objectivistic, information seeker or learning oriented paradigms of information and knowledge management.

Abstract

This paper is a theoretical analysis of the cognitive free-fall metaphor, used within the cognitive view, as a model for explaining the communication process between a generator and a receiver of a message. Its aim is to demonstrate that the idea of a cognitive free fall taking place within this communication process leads to apparent theoretical paradoxes, partly fostered by unclear definitions of key information-science concepts-namely, tokens, signs, information, and knowledge and their interrelatedness-and a naïve theoretical framework. The paper promotes a semiotically inspired model of communication that demonstrates that what takes place in communication is not a cognitive free fall, but rather a fall from a pragmatic level of knowing or knowledge to a level of representation or information. The paper further argues that the communication process more ideally can be expressed as a complex interrelation of emotion, information, and cognition.

Abstract

In a new study, computer scientists found that artificial intelligence systems fail a vision test a child could accomplish with ease. "It's a clever and important study that reminds us that 'deep learning' isn't really that deep," said Gary Marcus , a neuroscientist at New York University who was not affiliated with the work. The result takes place in the field of computer vision, where artificial intelligence systems attempt to detect and categorize objects. They might try to find all the pedestrians in a street scene, or just distinguish a bird from a bicycle (which is a notoriously difficult task). The stakes are high: As computers take over critical tasks like automated surveillance and autonomous driving, we'll want their visual processing to be at least as good as the human eyes they're replacing. It won't be easy. The new work accentuates the sophistication of human vision - and the challenge of building systems that mimic it. In the study, the researchers presented a computer vision system with a living room scene. The system processed it well. It correctly identified a chair, a person, books on a shelf. Then the researchers introduced an anomalous object into the scene - an image of elephant. The elephant's mere presence caused the system to forget itself: Suddenly it started calling a chair a couch and the elephant a chair, while turning completely blind to other objects it had previously seen. Researchers are still trying to understand exactly why computer vision systems get tripped up so easily, but they have a good guess. It has to do with an ability humans have that AI lacks: the ability to understand when a scene is confusing and thus go back for a second glance.

Abstract

Can information be objective and/or subjective? Based on Patrick Wilson's notion of public knowledge and a story of a sign on a tree, this paper argues that private information is not the same as subjective information, and that the very communicative process of making information makes information objective. It also argues that the objective sense of information-public knowledge-has been and will be most relevant to information science, hence questions concerning collective responsibility in collecting, preserving, and organizing information shall be considered.

Abstract

Any classification system should be evaluated with respect to a variety of philosophical and practical concerns. This paper explores several distinct issues: the nature of a work, the value of a statement, the contribution of information science to philosophy, the nature of hierarchy, ethical evaluation, pre- versus postcoordination, the lived experience of librarians, and formalization versus natural language. It evaluates a particular approach to classification in terms of each of these but draws general lessons for philosophical evaluation. That approach to classification emphasizes the free combination of basic concepts representing both real things in the world and the relationships among these; works are also classified in terms of theories, methods, and perspectives applied.

Abstract

Purpose - This paper aims to examine the relationships between meaning and truth as they may contribute to a constitutive definition of information. The thesis is primarily that "information" cannot be defined unless within the context of meaning and truth, and that any theory based on, or related to, information is not possible without the foundational definition. Design/methodology/approach - A review of related literatures and an arrangement of frameworks forms the design of this conceptual proposal. Findings - While other definitions of information have been presented, the present one integrates meaning and truth in ways that others do not. The thoroughgoing semantic examination provides a starting-point for a much deeper analysis of the integral role that language plays in the formation of any theory related to information. Truth tends not to be spoken of a great deal in information science; the definitional positioning of truth adds to a more complete definition and basis for theory. Originality/value - This paper proposes a new definitional and theoretical construct for information.
