Abstract

Die Informations- oder Wissensgesellschaft ist in aller Munde, das Verständnis derselben ist gleichwohl unklar. Unscharf ist auch das Verständnis der zugrunde liegenden Begriffe Information und Wissen sowie des Erwerbs von Information aus den verschiedenen medialen Repräsentationsformen. Allenfalls lässt sich eine gewisse Einseitigkeit bemerken, die durch den informationstechnischen Primat und an der Nachrichtentechnik orientierten Übertragungsformen geprägt ist. Ausgangspunkt der Erörterung ist die Beobachtung, dass Menschen Informationsbedürfnisse besitzen, die sie durch Inanspruchnahme verschiedenster externer Quellen und Hilfsmittel befriedigen wollen. Die neuartigen Speicher- und Findeformen führen zu übersteigerten Erwartungen, wenn man an all die Formulierungen mit virtuell, cyber, Hyper, Multimedia, Information Superhighway etc. denkt. Häufig wird dabei suggeriert, die veränderte mediale Präsentation habe neuartige und bessere Qualitäten für die Rezeption von Information, ohne dass die dabei beteiligten Prozesse völlig verstanden sind. Innerhalb eines konstruktivistischen Modells der kognitiven Informationsverarbeitung und der Rezeption medial gespeicherter Information werden Fragen der Darstellung und Rezeption von Information untersucht.

Abstract

Purpose Belkin and Robertson (1976a) reflected on the ethical implications of theoretical research in information science and warned that there was potential for abuse of knowledge gained by undertaking such research and applying it to information systems. In particular, they identified the domains of advertising and political propaganda that posed particular problems. The purpose of this literature review is to revisit these ideas in the light of recent events in global information systems that demonstrate that their fears were justified. Design/methodology/approach The authors revisit the theory in information science that Belkin and Robertson used to build their argument, together with the discussion on ethics that resulted from this work in the late 1970s and early 1980s. The authors then review recent literature in the field of information systems, specifically information retrieval, social media and recommendation systems that highlight the problems identified by Belkin and Robertson. Findings Information science theories have been used in conjunction with empirical evidence gathered from user interactions that have been detrimental to both individuals and society. It is argued in the paper that the information science and systems communities should find ways to return control to the user wherever possible, and the ways to achieve this are considered. Research limitations/implications The ethical issues identified require a multidisciplinary approach with research in information science, computer science, information systems, business, sociology, psychology, journalism, government and politics, etc. required. This is too large a scope to deal with in a literature review, and we focus only on the design and implementation of information systems (Zimmer, 2008a) through an information science and information systems perspective. Practical implications The authors argue that information systems such as search technologies, social media applications and recommendation systems should be designed with the recipient of the information in mind (Paisley and Parker, 1965), not the sender of that information. Social implications Information systems designed ethically and with users in mind will go some way to addressing the ill effects typified by the problems for individuals and society evident in global information systems. Originality/value The authors synthesize the evidence from the literature to provide potential technological solutions to the ethical issues identified, with a set of recommendations to information systems designers and implementers.

Abstract

The history of encyclopedias and wholly new forms of encyclopedias are briefly reviewed. The possibilities and problems that hypertext presents as a basis for new forms of encyclopedias are explored. The capabilities of current systems, both experimental and commercially available, are outlined, focusing on new possibilities for authoring and design and for reading the retrieval. Examples of applications already making use of hypertext are given.

Abstract

Within dynamic organizations, information systems often fail to adapt to changing requirements and structures. The book presents a different view of IS provision, based on end-user information systems construction, as a means of avoiding many of the recognized problems. Adopting a philosophy of constructivism, emphasizing psychological and social factors in information construction, the authors examine different types of systems across natural and social sciences

When we were all facing the turn of the century and the somewhat larger turn of the millennium, we left behind epochs of colonialism, imperialism, capitalism, nazism and racialism. Not that the ideologies mentioned does no longer exist, but their impact as grand narratives has gone and they now exist as fragmented discursive parts of their former, illusive hegemony. Parts that have been thrown into the pits of post modern complexity. The 21st century holds no answers, no new meaning, at most it provides human communication a certain self reflectivity due to the increasing egocentrism and individuality of people (i.e. still mostly western people). Another symptom of the loss of grand narratives is a feeling of loss of meaning in everyday life, as well as the state of democracies around the world. Democracy shivers in its void between anarchy and repressive dictatorship. The description 'information age' provides the times we are in with a useful sticker. It tents both back in time e.g. the late 20, century digitalisation and forward in time by givingr origin to the contemporary discourse of social semantics i.e. Dream society, Knowledge society, Post modern society, Risk society, Hypercomplex society etc. The phrase 'information age' implied the introduction of a paradigm shift, and now it is still here showing that paradigms do not shift, they slide. This paper outlines a manifest for librarians and librarianship of the information age. The information age puts the spotlight on the librarian, both regarding classical tasks such as classification and cataloguing as well as new tasks such as systems analysis and design or database searching.

Abstract

The idea of obtaining subject access to information by being able to visualize an information space, and to navigate through that space toward useful or interesting information, is attractive and plausible. However, this approach to subject access requires additional cognitive processing associated with the interaction of cognitive facilities that deal with concepts and those that deal with space. This additional cognitive processing may cause problems for users, particularly in dealing with the dimensions, the details, and the symbols of information space. Further, it seems likely that different cognitive abilities are associated with conceptual and spatial cognition. As a result, users who deal well with subject access using traditional conceptual approaches may experience difficulty in using visualization and navigation. An experiment designed to investigate the effects of different cognitive abilities on the use of both conceptual and spatial representations of information is outlined

Abstract

Anthropological inquiry suggests that all societies classify animals and plants in similar ways. Paradoxically, in the same cultures that have seen large advances in biological science, citizenry's practical knowledge of nature has dramatically diminished. Here we describe historical, cross-cultural and developmental research on how people ordinarily conceptualize organic nature (folkbiology), concentrating on cognitive consequences associated with knowledge devolution. We show that results on psychological studies of categorization and reasoning from "standard populations" fail to generalize to humanity at large. Usual populations (Euro-American college students) have impoverished experience with nature, which yields misleading results about knowledge acquisition and the ontogenetic relationship between folkbiology and folkpsychology. We also show that groups living in the same habitat can manifest strikingly distinct behaviors, cognitions and social relations relative to it. This has novel implications for environmental decision making and management, including commons problems.

Abstract

The philosophy of information (PI) is a new area of research with its own field of investigation and methodology. This article, based an the Herbert A. Simon Lecture of Computing and Philosophy I gave at Carnegie Mellon University in 2001, analyses the eighteen principal open problems in PI. Section 1 introduces the analysis by outlining Herbert Simon's approach to PI. Section 2 discusses some methodological considerations about what counts as a good philosophical problem. The discussion centers an Hilbert's famous analysis of the central problems in mathematics. The rest of the article is devoted to the eighteen problems. These are organized into five sections: problems in the analysis of the concept of information, in semantics, in the study of intelligence, in the relation between information and nature, and in the investigation of values.

Abstract

The Internet has led to an increase in the quantity and diversity of information available for searching. Furthermore, users are bombarded by a constant barrage of electronic messages in the form of e-mail, faxes, etc. This has led to a plethora of search engines, 'intelligent'agents, etc., that aim to help users in their quest for relevant information, or shield them against irrelevant information. All these systems aim to identify the potentially relevant information in among a large pool of available information. No unifying underlying theory for information discovery systems exist as yet. The aim of this article is to provide a logic-based framework for information discovery, and relate this to the traditional field of information retrieval. Furthermore, the often ignored user receives special emphasis. In information discovery, a good understanding of a user's (sometimes hidden) needs and beliefs is essential. We will develop a logic-based approach to express the mechanics of information discovery, while the pragmatics are based on an analysis of the underlying informational semantics of information carriers and information needs of users

Abstract

An epistemology, based in the information that rules our lives, is stated - Informationism - Information, or perhaps the message, reaches the brain as tiny impulses - quanta or useful information -, hitting and activating the neurones; as a consequence becoming quanta of useful information. The physical, psychic and pragmatic, etc. connotations of information are studied, including its energetic aspect; within a Cosmo vision. Among other matters, human neural evolution due to information is studied. Other neural information theories are also studied. Some definitions of information are quoted, as well as its connotations and peculiarities.

Abstract

The project Information Pricing was carried out during the summer semester 2004 by four students and two lecturers. Aim of the project was to develop a new product- and pricing concept for the research centre of the Public Library Cologne. The intention was to increase its competitiveness, especially in the business customer segment. The initiating factor for the project was the significant decrease in requests from 1997 to 2001. This paper describes the development of different attributes of information, analysing various pricing concepts of private and public information providers as well as the development of a pricing concept which is aligned to the requirements and performance of the research centre. The final result was an improved pricing system for an enhanced range of products. The first step was getting more familiar with the characteristics of information and the methods that can be used to measure the value of information. One of the key issues to consider is the value of information for a customer and the question how this value can be charged. In order to be capable of evaluating all issues of information pricing and to develop a solid pricing system, it was essential to analyse and assess pricing modules based on their intension of use. For example, the differentiation of the pricing concept with regard to certain user segments like business or private users as well as members and non-members. Another option is to define prices dependant on the requested response times for research tasks and thereby reflect the urgency of those tasks directly in the pricing concept. Furthermore, the qualitative and quantitative differentiation of information has to be taken into account. All described approaches - and also combinations of these - should be considered when developing a new pricing system. It is also important to recognize the special role of the research centre as a part of the public library. Libraries fulfil a public contract for their users. In this case it has to be ensured that people of all social backgrounds have the chance to gain access to all kind of information. While presenting results to the Public library Cologne some problems arose, mainly the gap between theoretical and practical feasibility. The final result was a practical pricing system, which is easy to implement for the research centre and which is described in the paper.
