Abstract

A review is presented of the relation between information and entropy, focusing on two main issues: the similarity of the formal definitions of physical entropy, according to statistical mechanics, and of information, according to information theory; and the possible subjectivity of entropy considered as missing information. The paper updates the 1983 analysis of Shaw and Davis. The difference in the interpretations of information given respectively by Shannon and by Wiener, significant for the information sciences, receives particular consideration. Analysis of a range of material, from literary theory to thermodynamics, is used to draw out the issues. Emphasis is placed on recourse to the original sources, and on direct quotation, to attempt to overcome some of the misunderstandings and oversimplifications that have occurred with these topics. Although it is strongly related to entropy, information is neither identical with it, nor its opposite. Information is related to order and pattern, but also to disorder and randomness. The relations between information and the "interesting complexity," which embodies both patterns and randomness, are worthy of attention.

Abstract

The relationship between information and complexity is analyzed using a detailed literature analysis. Complexity is a multifaceted concept, with no single agreed definition. There are numerous approaches to defining and measuring complexity and organization, all involving the idea of information. Conceptions of complexity, order, organization, and "interesting order" are inextricably intertwined with those of information. Shannon's formalism captures information's unpredictable creative contributions to organized complexity; a full understanding of information's relation to structure and order is still lacking. Conceptual investigations of this topic should enrich the theoretical basis of the information science discipline, and create fruitful links with other disciplines that study the concepts of information and complexity.

Abstract

It is suggested that, in addition to data, information and knowledge, the information sciences should focus on understanding, understood as a higher-order knowledge, with coherent and explanatory potential. The limited ways in which understanding has been addressed in the design of information systems, in studies of information behaviour, in formulations of information literacy and in impact studies are briefly reviewed, and future prospects considered. The paper is an extended version of a keynote presentation given at the i3 conference in June 2015.

Abstract

The use of quantum concepts and formalisms in the information sciences is assessed through an analysis of published literature. Five categories are identified: use of loose analogies and metaphors between concepts in quantum physics and library/information science; use of quantum concepts and formalisms in information retrieval; use of quantum concepts and formalisms in studying meaning and concepts; quantum social science, in areas adjacent to information science; and the qualitative application of quantum concepts in the information disciplines. Quantum issues have led to demonstrable progress in information retrieval and semantic modelling, with less clear-cut progress elsewhere. Whether there may be a future "quantum turn" in the information sciences is debated, the implications of such a turn are considered, and a research agenda outlined.

Abstract

This chapter considers the continuing relevance of the ideas of browsing, serendipity, information encountering and literature discovery in the context of the information retrieval (IR) environment of 2010, though its scope extends to the ideas in the broader contexts of information seeking and information-related behaviour. It is based around a selective review of the literature since 1990 and reflection and speculation on the results. The central focus is on questions of how the concept of browsing, serendipity and related ideas have changed in the new IR environment of the web and whether, indeed, they are still meaningfull concepts.

Abstract

This opinion piece considers the relative importance of individual and social factors in determining information behavior. It concludes that individual factors are more central and fundamental, although they may certainly be qualified by social and cultural factors and even though there are good reasons for studying and analyzing information behavior in terms of social groups. More studies of interesting emergent factors and behaviors in social settings would be valuable.

Abstract

Purpose The purpose of this paper is to re-examine the proposal that Luciano Floridi's philosphy of information (PI) may be an appropriate conceptual foundation for the discipline of library and information science (LIS). Design/methodology/approach A selective literature review and analysis are carried out. Findings It is concluded that LIS is in need of a new conceptual framework, and that PI is appropriate for this purpose. Originality/value Floridi proposed a close relationship between PI and LIS more than a decade ago. Although various authors have addressed the aspects of this relationship since then, this is the first proposal from an LIS perspective that PI be adopted as a basis for LIS.
