Abstract

Metadata (structured information about an object or collection of objects) is increasingly important to libraries, archives, and museums. And although librarians are familiar with a number of issues that apply to creating and using metadata (e.g., authority control, controlled vocabularies, etc.), the world of metadata is nonetheless different than library cataloging, with its own set of challenges. Therefore, whether you are new to these concepts or quite experienced with classic cataloging, this short (20 pages) introductory paper on metadata can be helpful

Abstract

A system of library classification that flashed across the inquiring mind of young Melvil Louis Kossuth Dewey (known as Melvil Dewey) in 1873 is still the most popular classification scheme.. The modern library classification begins with Dewey Decimal Classification (DDC). Melvil Dewey devised DDC in 1876. DDC has is credit of 128 years of boudless success. The DDC is being taught as a practical subject throughout the world and it is being used in majority of libraries in about 150 countries. This is the result of continuous revision that 22nd Edition of DDC has been published in July 2003. No other classification scheme has published so many editions. Some welcome changes have been made in DDC 22. To reduce the Christian bias in 200 religion, the numbers 201 to 209 have been devoted to specific aspects of religion. In the previous editions these numbers were devoted to Christianity. to enhance the classifier's efficiency, Table 7 has been removed from DDC 22 and the provision of adding group of persons is made by direct use of notation already available in schedules and in notation -08 from Table 1 Standard Subdivision. The present book is an attempt to explain, with suitable examples, the salient provisions of DDC 22. The book is written in simple language so that the students may not face any difficulty in understanding what is being explained. The examples in the book are explained in a step-by-step procedure. It is hoped that this book will prove of great help and use to the library professionals in general and library and information science students in particular.

Abstract

"Clearly details the conceptual and practical notions of controlled vocabularies. . provides a crash course for newcomers and offers experienced practitioners a common frame of reference. A valuable book." - Christine Connors, TriviumRLG LLC The Accidental Taxonomist is the most comprehensive guide available to the art and science of building information taxonomies. Heather Hedden-one of today's leading writers, instructors, and consultants on indexing and taxonomy topics-walks readers through the process, displaying her trademark ability to present highly technical information in straightforward, comprehensible English. Drawing on numerous real-world examples, Hedden explains how to create terms and relationships, select taxonomy management software, design taxonomies for human versus automated indexing, manage enterprise taxonomy projects, and adapt taxonomies to various user interfaces. The result is a practical and essential guide for information professionals who need to effectively create or manage taxonomies, controlled vocabularies, and thesauri. "A wealth of descriptive reference content is balanced with expert guidance. . Open The Accidental Taxonomist to begin the learning process or to refresh your understanding of the depth and breadth of this demanding discipline." - Lynda Moulton, Principal Consultant, LWM Technology Services "From the novice taxonomist to the experienced professional, all will find helpful, practical advice in The Accidental Taxonomist." - Trish Yancey, TCOO, Synaptica, LLC "This book squarely addresses the growing demand for and interest in taxonomy. ...Hedden brings a variety of background experience, including not only taxonomy construction but also abstracting and content categorization and creating back-of-the-book indexes. These experiences serve her well by building a broad perspective on the similarities as well as real differences between often overlapping types of work." - Marjorie M. K.

Abstract

Das Buch gibt einen umfassenden Überblick über vorhandene Thesauri und Klassifikationen. Es liefert detaillierte Beschreibungen zu mehr als 150 Klassifikationen und Thesauri aus Naturwissenschaften, Technik, Wirtschaft und Patentwesen. Da gegenwärtig eine aktuelle Zusammenstellung international verfügbarer Thesauri und Klassifikationen fehlt, schließt das vorliegende Buch diese Lücke und kann somit dazu beitragen, Doppelarbeit bei der Erstellung von Thesauri und Klassifikationen zu verhindern und den intellektuellen wie kostenintensiven Aufwand zu minimieren. Zusätzlich bietet dieses Nachschlagewerk mit einem umfangreichen Index den Informationsspezialisten Unterstützung bei der Formulierung präziser Rechercheanfragen, indem es Informationen über Vorhandensein, Aufbau und Verfügbarkeit der Thesauri und Klassifikationen bereitstellt, die für die Recherche genutzt werden können. Das Buch wendet sich an alle Information Professionals, die Dokumentationssprachen aufbauen und nutzen.

Das Buch mit seiner Auswahl von über 150 Klassifikationen und Thesauri aus Naturwissenschaft, Technik, Wirtschaft und Patenwesen macht es zu einem brauchbaren Nachschlagewerk, zumal auch ein umfassender Index nach Sachgebieten, nach Datenbanken und nach Klassifikationen und Thesauri angeboten wird. Nach einer 13-seitigen Einführung (Kapitel 1 und 2) folgt mit dem 3. Kapitel die "Darstellung von Klassifikationen und Thesauri", im wesentlichen aus den Beschreibungen der Hersteller zusammengestellt. Hier werden Dokumentationssprachen der Fachgebiete - Naturwissenschaften (3.1) und deren Spezialisierungen wie zum Beispiel "Biowissenschaften und Biotechnologie", "Chemie" oder "Umwelt und Ökonomie", aber auch "Mathematik und Informatik" (?) auf 189 Seiten vorgestellt, - Technik mit zum Beispiel "Fachordnung Technik", "Subject Categories (INIS/ ETDE) mit 17 Seiten verhältnismäßig knapp abgehandelt, - Wirtschaft mit "Branchen-Codes", "Product-Codes", "Länder-Codes"",Fachklas-sifikationen" und "Thesauri" ausführlich auf 57 Seiten präsentiert, - Patente und Normen mit zum Beispiel "Europäische Patentklassifikation" oder "International Patent Classification" auf 33 Seiten umrissen. Jedes Teilgebiet wird mit einer kurzen Beschreibung eingeleitet. Danach folgen die jeweiligen Beschreibungen mit den Merkmalen: "Anschrift des Erstellers", "Themen-gebiet(e)", "Sprache", "Verfügbarkeit", "An-wendung" und "Ouelle(n)". "Das Buch wendet sich an alle Information Professionals, die Dokumentationssprachen aufbauen und nutzen" heißt es in der Verlagsinformation. Zwar ist es nicht notwendig, die informationswissenschaftlichen Aspekte der Klassifikationen und Thesauri abzuhandeln, aber ein Hinweis auf die Bedeutung der Information und Dokumentation und/oder der Informationswissenschaft wäre schon angebracht, um in der Welt der Informations- und Wissenswirtschaft zu demonstrieren, welchen Beitrag unsere Profession leistet. Andernfalls bleibt das Blickfeld eingeschränkt und der Anschluss an neuere Entwicklungen ausgeblendet. Dieser Anknüpfungspunkt wäre beispielsweise durch einen Exkurs über Topic Map/Semantic Web gegeben. Der Verlag liefert mit der Herausgabe die ses Kompendiums einen nützlichen ersten Baustein zu einem umfassenden Verzeichnis von Thesauri und Klassifikationen."

Abstract

The World Wide Web is rapidly filling with more text than anyone could have imagined even a short time ago, but the task of isolating relevant parts of this vast information has become just that much more daunting. Richard Belew brings a cognitive perspective to the study of information retrieval as a discipline within computer science. He introduces the idea of Finding Out About (FDA) as the process of actively seeking out information relevant to a topic of interest and describes its many facets - ranging from creating a good characterization of what the user seeks, to what documents actually mean, to methods of inferring semantic clues about each document, to the problem of evaluating whether our search engines are performing as we have intended. Finding Out About explains how to build the tools that are useful for searching collections of text and other media. In the process it takes a close look at the properties of textual documents that do not become clear until very large collections of them are brought together and shows that the construction of effective search engines requires knowledge of the statistical and mathematical properties of linguistic phenomena, as well as an appreciation for the cognitive foundation we bring to the task as language users. The unique approach of this book is its even handling of the phenomena of both numbers and words, making it accessible to a wide audience. The textbook is usable in both undergraduate and graduate classes on information retrieval, library science, and computational linguistics. The text is accompanied by a CD-ROM that contains a hypertext version of the book, including additional topics and notes not present in the printed edition. In addition, the CD contains the full text of C.J. "Keith" van Rijsbergen's famous textbook, Information Retrieval (now out of print). Many active links from Belew's to van Rijsbergen's hypertexts help to unite the material. Several test corpora and indexing tools are provided, to support the design of your own search engine. Additional exercises using these corpora and code are available to instructors. Also supporting this book is a Web site that will include recent additions to the book, as well as links to sites of new topics and methods.

Rez. in: nfd 54(2003) H.5, S.314 (W. Ratzek): "Um entscheidungsrelevante Daten aus der ständig wachsenden Flut von mehr oder weniger relevanten Dokumenten zu extrahieren, müssen Unternehmen, öffentliche Verwaltung oder Einrichtungen der Fachinformation effektive und effiziente Filtersysteme entwickeln, einsetzen und pflegen. Das vorliegende Lehrbuch von Holger Nohr bietet erstmalig eine grundlegende Einführung in das Thema "automatische Indexierung". Denn: "Wie man Information sammelt, verwaltet und verwendet, wird darüber entscheiden, ob man zu den Gewinnern oder Verlierern gehört" (Bill Gates), heißt es einleitend. Im ersten Kapitel "Einleitung" stehen die Grundlagen im Mittelpunkt. Die Zusammenhänge zwischen Dokumenten-Management-Systeme, Information Retrieval und Indexierung für Planungs-, Entscheidungs- oder Innovationsprozesse, sowohl in Profit- als auch Non-Profit-Organisationen werden beschrieben. Am Ende des einleitenden Kapitels geht Nohr auf die Diskussion um die intellektuelle und automatische Indexierung ein und leitet damit über zum zweiten Kapitel "automatisches Indexieren. Hier geht der Autor überblickartig unter anderem ein auf - Probleme der automatischen Sprachverarbeitung und Indexierung - verschiedene Verfahren der automatischen Indexierung z.B. einfache Stichwortextraktion / Volltextinvertierung, - statistische Verfahren, Pattern-Matching-Verfahren. Die "Verfahren der automatischen Indexierung" behandelt Nohr dann vertiefend und mit vielen Beispielen versehen im umfangreichsten dritten Kapitel. Das vierte Kapitel "Keyphrase Extraction" nimmt eine Passpartout-Status ein: "Eine Zwischenstufe auf dem Weg von der automatischen Indexierung hin zur automatischen Generierung textueller Zusammenfassungen (Automatic Text Summarization) stellen Ansätze dar, die Schlüsselphrasen aus Dokumenten extrahieren (Keyphrase Extraction). Die Grenzen zwischen den automatischen Verfahren der Indexierung und denen des Text Summarization sind fließend." (S. 91). Am Beispiel NCR"s Extractor/Copernic Summarizer beschreibt Nohr die Funktionsweise.
Im fünften Kapitel "Information Extraction" geht Nohr auf eine Problemstellung ein, die in der Fachwelt eine noch stärkere Betonung verdiente: "Die stetig ansteigende Zahl elektronischer Dokumente macht neben einer automatischen Erschließung auch eine automatische Gewinnung der relevanten Informationen aus diesen Dokumenten wünschenswert, um diese z.B. für weitere Bearbeitungen oder Auswertungen in betriebliche Informationssysteme übernehmen zu können." (S. 103) "Indexierung und Retrievalverfahren" als voneinander abhängige Verfahren werden im sechsten Kapitel behandelt. Hier stehen Relevance Ranking und Relevance Feedback sowie die Anwendung informationslinguistischer Verfahren in der Recherche im Mittelpunkt. Die "Evaluation automatischer Indexierung" setzt den thematischen Schlusspunkt. Hier geht es vor allem um die Oualität einer Indexierung, um gängige Retrievalmaße in Retrievaltest und deren Einssatz. Weiterhin ist hervorzuheben, dass jedes Kapitel durch die Vorgabe von Lernzielen eingeleitet wird und zu den jeweiligen Kapiteln (im hinteren Teil des Buches) einige Kontrollfragen gestellt werden. Die sehr zahlreichen Beispiele aus der Praxis, ein Abkürzungsverzeichnis und ein Sachregister erhöhen den Nutzwert des Buches. Die Lektüre förderte beim Rezensenten das Verständnis für die Zusammenhänge von BID-Handwerkzeug, Wirtschaftsinformatik (insbesondere Data Warehousing) und Künstlicher Intelligenz. Die "Grundlagen der automatischen Indexierung" sollte auch in den bibliothekarischen Studiengängen zur Pflichtlektüre gehören. Holger Nohrs Lehrbuch ist auch für den BID-Profi geeignet, um die mehr oder weniger fundierten Kenntnisse auf dem Gebiet "automatisches Indexieren" schnell, leicht verständlich und informativ aufzufrischen."

Rez. in: BuB 56(2004) H.12, S.743 (H, Meinhardt): "1987 erstmals erschienen und seitdem ein Klassiker unter den Lehrbüchern im Feld der Information Science, liegt nunmehr die dritte, deutlich veränderte Auflage vor. Notwendig geworden war die Überarbeitung vor allem durch die Dynamik im Bereich der Informationstechnologien und deren Auswirkungen sowohl auf die Praxis der Informationsspezialisten wie auch die Disziplin selber. Augenfälligste Veränderung ist denn auch ein neues Kapitel zu »Internet und Informationswissenschaft«. »Chemical librarians« Zunächst einige Worte zu den Autoren, die dem einen oder anderen vielleicht nicht bekannt sind: Brian C. Vickery und Alina Vickery sind beide von ihrer Ausbildung her Chemiker und waren als Ehepartner (Alina Vickery starb Ende 2001) auch beruflich vielfältig gemeinsam tätig. Wie viele Chemiker (man denke nur Eugene Garfield, den Begründer der modernen Szientometrie) sensibilisiert für den Umgang mit enormen Informationsmengen und damit Informationsproblemen, zudem als »chemical librarian« (Brian C. Vickery) und Mitarbeiter von chemischen Fachzeitschriften auch professionell beschäftigt mit Fragen des Fachinformationstransfers, haben sie sich (insbesondere Brian C. Vickery) frühzeitig und kontinuierlich informationswissenschaftlich betätigt. Resultat ist eine Fülle von Publikationen, vor allem zu den Bereichen Indexieren, Klassifizieren, Information Retrieval, auch zur Geschichte der wissenschaftlichen Kommunikation (alle Arbeiten sind im Anhang aufgelistet). Brian C. Vickery war außerdem, das dürfte für Bibliothekare von Interesse sein, als Deputy beim Aufbau der National Lending Library for Science and Technology (NLLST) in Boston Spa beteiligt, die ihre Arbeit 1961 aufnahm und 1973 mit in die neu gegründete British Library einging. Und es sei hier schon vorab bemerkt, dass der immer wiederkehrende Bezug von informationswissenschaftlichen Fragestellungen auf die bibliothekarische Praxis ein Vorzug dieses Buches ist.
Ungewohnte Einordnung und Gewichtung Von der Konzeption her ist das Buch am ehesten als eine Art einführendes Handbuch zu beschreiben, das sehr stark Querschnittscharakter hat. Dem entspricht die inhaltlich weit gespannte Gliederung, die die meisten informationswissenschaftlichen Bereiche streift. Die Autoren verfolgen explizit nicht das Ziel, eine Art Manual für die Informationspraxis oder für das Informationsmanagement vorzulegen, sondern versprechen einen Mix aus theoretischer Annäherung und praxisorientierter Handreichung - und enttäuschen damit nicht. Der deutsche Leser, der mit hiesigen Lehrbüchern zur Informationswissenschaft nicht gerade verwöhnt ist und sich in aller Regel aus vielen Quellen Puzzleartig sein Bild von »Informationswissenschaft« zusammenstoppeln muss (eine nach wie vor rühmliche Ausnahme sind die mehrbändigen »Grundlagen der praktischen Information und Dokumentation«, deren Neuauflage gerade erschienen sind), wird vieles, allerdings in ungewohnter Einordnung und Gewichtung, hier gesammelt vorfinden. Im Einzelnen gehen Vickery auf folgende Bereiche ein: Information und Gesellschaft, Informationstransfer in natürlichen, sozialen, maschinellen Umgebungen, Besonderheiten und Ausprägungen menschlicher Kommunikation und Informationsbedürfnisse, das gesamte Gebiet des Information Retrieval, Wissensrepräsentation, Informationsvermittlung, Informationssysteme und deren Evaluation, Internet und Informationswissenschaft.
Soziologisch geprägt Das alles auf nicht einmal 350 Seiten: Hier kann es also immer nur um ein »Anreißen« gehen, was sich immer wieder, zum Beispiel in den Abschnitten zu Information Retrieval oder zu Formen der Wissensrepräsentation, schmerzhaft bemerkbar macht. Auf Klassifikationen, Thesauri, Formen des Abstracting und so weiter wird so gut wie nicht eingegangen. Hier ist generell zu fragen, ob die Gewichtung, die die Autoren vornehmen, sinnvoll ist. Ihr Ansatz, Informationswissenschaft zu beschreiben als »the study of the communication of information in sociery«, ist ein sehr weiter und findet seinen Niederschlag in überdimensionierten Abschnitten, die stark soziologisch geprägt sind, ohne wirklich erhellend zu sein; dazu sind die Aussagen, zum Beispiel zu Reichweiten von Kommunikation oder zu verschiedenen Kommunikationstypen, zu allgemein. Bedeutsamer, da dieser umfassende Ansatz überhaupt nicht durchgehalten wird, sondern sich immer stärker verengt hin auf Kommunikation von wissenschaftlicher Information, ist jedoch, dass auch dieses Buch letztlich den Eindruck hinterlässt, Informationswissenschaft sei ein Konglomerat miteinander relativ unverbundener Theorien und Bausteine. Dieser Eindruck, der sich beim Lesen auch deshalb immer wieder aufdrängt, weil sowohl die historische EntwicklungderDisziplin nur sehr verknappt (generell USA-zentriert) wie auch die Abgrenzung/Überschneidungzu anderen Wissenschaften wenig thematisiert wird (ganz stark spürbarim Kapitel 3 »Widercontexts of information transfer«), mildert sich etwas durch die sehr verdienstvolle Auflistung von bekannten Informationsspezialisten im Anhang und die Visualisierung der Informationswissenschaft, ihrer Zweige und bedeutender Vertreter, in Form einer Art »Landkarte«.
