Abstract

Information management (IM) has exploded in importance in recent years and yet until now there has been no Reader to introduce students to the subject. This comprehensive international collection introduces you to the core topics and methodologies used in teaching IM, namely: information behaviour; environmental scanning and decision making; knowledge management; and information strategy. These peer-reviewed papers represent an elite selection from the respected "Information Research" journal, each carefully updated to take into account recent developments. This book is an essential introduction to IM for all students on courses in library and information science, IM, information systems, business information technology, business management, computer science and information technology; as well as for practitioners working in a wide range of organizations providing information services.

Allen strikes a realistic note of the institutional importance of trust across teams of academics and administrators, and subsequently of the political behavior of academics and computer services administrators/ managers and the relation of the latter to information strategy formulation. Research was conducted at 12 university sites, information strategy process documents were analyzed, and 20 informants were interviewed at each site. The study's research focused on cross-case analysis (instead of an iterative approach to collection and analysis of data), research was longitudinal, and a grounded theory approach was employed. According to the author, findings confirm a similar position taken by Pettigrew (1977): "development of information strategy is the outcome of negotiated political relations" (p. 177). And for such negotiated political relations, the author concludes, trust is a necessary ingredient. It is important to reiterate that IM's scope requires a diversity of study methods and methodologies to address all issues involved. A multiplicity of information and IM definitions and the number of local and global issues that must be addressed, along with information's significance as resource and/or commodity in different types of organizations, necessitate diversity in information research. Each chapter has demonstrated a need to cover many aspects of IM and to ensure that there is as much clarity in that effort as possible, and yet differentiation of IM from other related fields such as KM clearly remains a top issue. As with any other effort to define a field's boundaries, the task at hand is not easy, but while definitions and boundaries are being worked out, there is always an opportunity to engage in fruitful discussions about scope and critical issues in information research."

Abstract

The main goal of this book is to transfer new research results from the fields of advanced computer sciences and information science to the design of new search engines. The readers will have a better idea of the new trends in applied research. The achievement of relevant, organized, sorted, and workable answers- to name but a few - from a search is becoming a daily need for enterprises and organizations, and, to a greater extent, for anyone. It does not consist of getting access to structural information as in standard databases; nor does it consist of searching information strictly by way of a combination of key words. It goes far beyond that. Whatever its modality, the information sought should be identified by the topics it contains, that is to say by its textual, audio, video or graphical contents. This is not a new issue. However, recent technological advances have completely changed the techniques being used. New Web technologies, the emergence of Intranet systems and the abundance of information on the Internet have created the need for efficient search and information access tools.
Recent technological progress in computer science, Web technologies, and constantly evolving information available on the Internet has drastically changed the landscape of search and access to information. Web search has significantly evolved in recent years. In the beginning, web search engines such as Google and Yahoo! were only providing search service over text documents. Aggregated search was one of the first steps to go beyond text search, and was the beginning of a new era for information seeking and retrieval. These days, new web search engines support aggregated search over a number of vertices, and blend different types of documents (e.g., images, videos) in their search results. New search engines employ advanced techniques involving machine learning, computational linguistics and psychology, user interaction and modeling, information visualization, Web engineering, artificial intelligence, distributed systems, social networks, statistical analysis, semantic analysis, and technologies over query sessions. Documents no longer exist on their own; they are connected to other documents, they are associated with users and their position in a social network, and they can be mapped onto a variety of ontologies. Similarly, retrieval tasks have become more interactive and are solidly embedded in a user's geospatial, social, and historical context. It is conjectured that new breakthroughs in information retrieval will not come from smarter algorithms that better exploit existing information sources, but from new retrieval algorithms that can intelligently use and combine new sources of contextual metadata.

Content

Enthält u.a. folgende Aussage von J. Aitchison u. S. Dextre Clarke: "We face a paradox. Ostensibly, the need and the opportunity to apply thesauri to information retrieval are greater than ever before. On the other hand, users resist most efforts to persuade them to apply one. The drive for interoperability of systems means we must design our vocabularies for easy integration into downstream applications such as content management systems, indexing/metatagging interfaces, search engines, and portals. Summarizing the search for vocabularies that work more intuitively, we see that there are trends working in opposite directions. In the hugely popular taxonomies an the one hand, relationships between terms are more loosely defined than in thesauri. In the ontologies that will support computer-to-computer communications in AI applications such as the Semantic Web, we see the need for much more precisely defined term relationships."

Rez. in: Mitt VÖB 59(2006) H.2, S.83-88 (O. Oberhauser): "Dieser neue Sammelband möchte Interessenten aus den Bereichen Informationswissenschaft, Bibliothekswesen sowie Sozial- und Evolutionspsychologie aktuelle Entwicklungen und neue theoretische Ansätze auf dem Gebiet des menschlichen Informationsverhaltens-human information behavio(u)r bzw. kurz HIB - vermitteln. Es geht dabei um die komplexen Informationsprozesse, die in das alltägliche Sozialverhalten und die Lebensabläufe menschlicher Individuen eingebettet sind. Die beiden Herausgeber sind in diesem Teilbereich der Informationswissenschaft auch durch eine Reihe anderer Publikationen einschlägig ausgewiesen: Amanda Spink (vormals Universität Pittsburgh), die sich kürzlich selbst in aller Bescheidenheit als "world-class ICT researcher" beschrieb,' ist Professorin an der Technischen Universität Queensland (Australien); Charles Cole ist Research Associate (wissenschaftlicher Projektmitarbeiter) an der McGill University in Montreal und selbständiger Berater für Informationsdesign. Gemeinsam haben Spink und Cole zuletzt, ebenfalls bei Springer, eine weitere Aufsatzsammlung - New Directions in Cognitive Information Retrieval (2005) - herausgegeben. Das Buch versammelt zwölf Beiträge ("Kapitel"), die in fünf Sektionen dargeboten werden, wobei es sich allerdings bei den Sektionen 1 und 5 (= Kapitel 1 und 12) um Einleitung und Zusammenschau der Herausgeber handelt. Während erstere eigentlich nur eine Übersicht über die Gliederung und die Beiträge des Buches, die jeweils mit Abstracts beschrieben werden, darstellt, kann letztere als eigenständiger Beitrag gelten, der versucht, die in diesem Band angesprochenen Aspekte in einem vorläufigen HIB-Modell zu integrieren.
