Abstract

LIS professionals use structures for organizing knowledge when they catalog and classify objects in the collection, when they develop databases, when they design customized taxonomies, or when they search online. Structures for Organizing Knowledge: Exploring Taxonomies, Ontologies, and Other Schema explores and explains this basic function by looking at three questions: 1) How do we organize objects so that they make sense and are useful? 2) What role do categories, classifications, taxonomies, and other structures play in the process of organizing? 3) What do information professionals need to know about organizing behaviors in order to design useful structures for organizing knowledge? Taking a broad, yet specialized approach that is a first in the field, this book answers those questions by examining three threads: traditional structures for organizing knowledge; personal structures for organizing knowledge; and socially-constructed structures for organizing knowledge. Through these threads, it offers avenues for expanding thinking on classification and classification schemes, taxonomy and ontology development, and structures. Both a history of the development of taxonomies and an analysis of current research, theories, and applications, this volume explores a wide array of topics, including the new digital, social aspect of taxonomy development. Examples of subjects covered include: Formal and informal structures Applications of knowledge structures Classification schemes Early taxonomists and their contributions Social networking, bookmarking, and cataloging sites Cataloging codes Standards and best practices Tags, tagging, and folksonomies Descriptive cataloging Metadata schema standards Thought exercises, references, and a list of helpful websites augment each section. A final chapter, "Thinking Ahead: Are We at a Crossroads?" uses "envisioning exercises" to help LIS professionals look into the future.

Abstract

Drawing on the research of experts from the fields of computing and library science, this ground-breaking work will show you how to combine two very different approaches to classification to create more effective, user-friendly information-retrieval systems. * Provides an interdisciplinary overview of current and potential approaches to organizing information by subject * Covers both pure computer science and pure library science topics in easy-to-understand language accessible to audiences from both disciplines * Reviews technological standards for representation, storage, and retrieval of varied knowledge-organization systems and their constituent elements * Suggests a collaborative approach that will reduce duplicate efforts and make it easier to find solutions to practical problems.

Im zweiten Kapitel, das ich für besonders lesenswert halte, beschäftigt sich die Autorin mit vier als "preliminaries" bezeichneten Stadien im Prozess des Designs von Informationssystemen: "information needs analysis" (welche Informationen werden benötigt), "task analysis" (für welche Aufgaben werden die Informationen benötigt), "resource analysis" (welche persönliche Kompetenzen bzw. praktischen Fähigkeiten stehen den präsumtiven Benutzern bereits zur Verfügung), "user modelling" (Segmentierung bzw. Kategorisierung der Anwender). In diesem Zusammenhang werden auch Begriffe wie "information audit" oder "needs assessment" erläutert sowie methodische Frage angerissen; zudem wird eine kleine Fallstudie als Beispiel präsentiert. Das folgende Kapitel ("Searching and finding") konzentriert sich auf die Informationssuche bzw. auf Retrievalaspekte. Dabei werden die Strategien des Suchens und Browsings im allgemeinen wie auch im besonderen (z.B. Boolesche Suchformulierungen, bibliothekarische Klassifikationen und Webtaxonomien) vorgestellt. Daran schliesst sich ein Kapitel über Dokumente und Dokumentbeschreibungen, in dem auf formale wie auch auf inhaltliche Aspekte der Dokumente (Metadaten vs. Thesauri) eingegangen wird. Kapitel 5 hat dann wieder einen höheren Neuigkeitswert für den bibliothekarischen Leser, da es hier um "interface and display design" geht. Begriffe wie Mensch-Maschine-Schnittstelle und mentale Modelle der Interaktion mit Computern (Metaphern) werden hier ebenso vorgestellt wie Interaktionsstile (z.B. Kommandosprachen vs. Formulare, Web-Kataloge) und grundsätzliche Designprinzipien (Bildschirmlayout, Navigation, Graphik etc.) Das darauf folgende kurze Kapitel "Management and maintenance" thematisiert Aspekte wie Content Management sowie organisatorische Fragen. In "Evaluation", dem abschliessenden Kapitel, geht es schliesslich um die Abschätzung von Wert und Qualität der durchgeführten "Informationsarchitektur", also um Wirksamkeit und Leistungsfähigkeit eines Systems (gemessen z.B. mittels bekannter Parameter wie Precision und Recall), aber auch um die damit erzielte Benutzerzufriedenheit.

Chu's intent with this book is clear throughout the entire text. With this presentation, she writes with the novice in mind or as she puls it in the Preface, "to anyone who is interested in learning about the field, particularly those who are new to it." After reading the text, I found that this book is also an appropriate reference book for those who are somewhat advanced in the field. I found the chapters an information retrieval models and techniques, metadata, and AI very informative in that they contain information that is often rather densely presented in other texts. Although, I must say, the metadata section in Chapter 3 is pretty basic and contains more questions about the area than information. . . . It is an excellent book to have in the classroom, an your bookshelf, etc. It reads very well and is written with the reader in mind. If you are in need of a more advanced or technical text an the subject, this is not the book for you. But, if you are looking for a comprehensive, manual that can be used as a "flip-through," then you are in luck."

Other selected specialized metadata element sets or schemas, such as Government Information Locator Service (GILS), are presented. Attention is brought to the different sets of elements and the need for linking up these elements across metadata schemes from a semantic point of view. It is no surprise, then, that after the presentation of additional specialized sets of metadata from the educational community and the arts sector, attention is turned to the discussion of Crosswalks between metadata element sets or the mapping of one metadata standard to another. Finally, the five appendices detailing elements found in Dublin Core, GILS, ARIADNE versions 3 and 3. 1, and Categories for the Description of Works of Art are an excellent addition to this chapter's focus on metadata and communities of practice. Chapters 3-6 provide an up-to-date account of the use of metadata standards in Libraries from the point of view of a community of practice. Some of the content standards included in these four chapters are AACR2, Dewey Decimal Classification (DDC), and Library of Congress Subject Classification. In addition, uses of MARC along with planned implementations of the archival community's encoding scheme, EAD, are covered in detail. In a way, content in these chapters can be considered as a refresher course on the history, current state, importance, and usefulness of the above-mentioned standards in Libraries. Application of the standards is offered for various types of materials, such as monographic materials, continuing resources, and integrating library metadata into local catalogs and databases. A review of current digital library projects takes place in Chapter 7. While details about these projects tend to become out of date fast, the sections on issues and problems encountered in digital projects and successes and failures deserve any reader's close inspection. A suggested model is important enough to merit a specific mention below, in a short list format, as it encapsulates lessons learned from issues, problems, successes, and failures in digital projects. Before detailing the model, however, the various projects included in Chapter 7 should be mentioned. The projects are: Colorado Digitization Project, Cooperative Online Resource Catalog (an Office of Research project by OCLC, Inc.), California Digital Library, JSTOR, LC's National Digital Library Program and VARIATIONS.
