Abstract

This book covers the key aspects of information architecture: core elements of information management - indexing, cataloguing and classification - organising and recording information in the digital environment. The book also focuses on design - specifically user-centred design: designing information systems that support the needs of users, by providing attractive, intuitive interfaces that support a range of information tasks and accommodate a range of individual resources. Key Features: (1) Is aimed at information professionals - existing texts in this emerging area are primarily aimed at web managers. (2) Is a straightforward introduction to the area. The Author: Dr Batley is a senior lecturer at the London Metropolitan University with teaching and research in the areas of organisation and retrieval of information and knowledge resources. Having completed a PhD on factors affecting the retrieval of information from picture databases in 1989, she worked as a subject librarian at the University of East London, before taking up her current post in 1996. Dr Batley is the author of another Chandos book, 'Classification in Theory and Practice'. Readership: The book is aimed at library and information practitioners; students of librarianship, information studies and information management. Contents: Introduction to information architecture Managing content Document description and content analysis Needs, task and resource analysis Indexing and ontologies Metadata Classification and taxonomy creation User-centred design and evaluation

Dem Begriff IA kann also nicht mehr ausgewichen werden. Was ist nun wirklich damit gemeint? Das IIA gibt folgende Definition: "1. Das strukturelle Design von gemeinschaftlich genutzten Informationsumgebungen. 2. Die Kunst und Wissenschaft Websites, Intranets, Online-Communitys [sic!] und Software zu strukturieren und Bezeichnungssysteme zu entwickeln, um Usability und die Auffindbarkeit von Inhalten herzustellen. 3. Eine sich herauskristallisierende Community von Praktikern, die Designund Architekturprinzipien in die digitale Landschaft einführen will." Bei Rosenfeld & Morville (Auflage 1998) heisst es - nicht unähnlich, aber doch nicht deckungsgleich -, IA sei: 1. The combination of organization, labeling, and navigation schemes within an information system. 2. The structural design of an information space to facilitate task completion and intuitive access to content. 3. The art and science of structuring and classifying web sites and intranets to help people find and manage information. 4. An emerging discipline and community of practice focusing on bringing principles of design and architecture to the digital landscape. IA hat aber wohl nicht nur mit dem Design von Websites zu tun. Sue Batley, deren Buch sich im Gegensatz zu jenem der beiden amerikanischen Autoren nicht an Webdesigner, sondern an Informationsspezialisten wendet, betont im ersten Kapitel, dass es gegenwärtig (noch) keine allgemeingültige Definition für IA gebe; zuviel sei noch in Entwicklung bzw. im Fluss. Sie sieht, mit Blick auf die Zielgruppe der Informationsspezialisten, IA als eine Verbindung der Kernelemente des Informationsmanagements mit den Prinzipien des benutzerzentrierten Designs. Die Verbesserung von Auffindbarkeit ("increasing findability") gilt ihr hier als die wesentliche Aktivität. Als zentrale Begriffe in diesem Zusammenhang stellt Batley daher auch "indexes and indexing", "classification", "cataloguing" sowie "user-centered design" (von Informationssystemen) vor.
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.

Abstract

This book examines a core topic in traditional librarianship: classification. Classification has often been treated as a sub-set of cataloguing and indexing with relatively few basic textbooks concentrating solely an the theory and practice of classifying resources. This book attempts to redress the balance somewhat. The aim is to demystify a complex subject, by providing a sound theoretical underpinning, together with practical advice and promotion of practical skills. The text is arranged into five chapters: Chapter 1: Classification in theory and practice. This chapter explores theories of classification in broad terms and then focuses an the basic principles of library classification, introducing readers to technical terminology and different types of classification scheme. The next two chapters examine individual classification schemes in depth. Each scheme is explained using frequent examples to illustrate basic features. Working through the exercises provided should be enjoyable and will enable readers to gain practical skills in using the three most widely used general library classification schemes: Dewey Decimal Classification, Library of Congress Classification and Universal Decimal Classification. Chapter 2: Classification schemes for general collections. Dewey Decimal and Library of Congress classifications are the most useful and popular schemes for use in general libraries. The background, coverage and structure of each scheme are examined in detail in this chapter. Features of the schemes and their application are illustrated with examples. Chapter 3: Classification schemes for specialist collections. Dewey Decimal and Library of Congress may not provide sufficient depth of classification for specialist collections. In this chapter, classification schemes that cater to specialist needs are examined. Universal Decimal Classification is superficially very much like Dewey Decimal, but possesses features that make it a good choice for specialist libraries or special collections within general libraries. It is recognised that general schemes, no matter how deep their coverage, may not meet the classification needs of some collections. An answer may be to create a special classification scheme and this process is examined in detail here. Chapter 4: Classifying electronic resources. Classification has been reborn in recent years with an increasing need to organise digital information resources. A lot of work in this area has been conducted within the computer science discipline, but uses basic principles of classification and thesaurus construction. This chapter takes a broad view of theoretical and practical issues involved in creating classifications for digital resources by examining subject trees, taxonomies and ontologies. Chapter 5: Summary. This chapter provides a brief overview of concepts explored in depth in previous chapters. Development of practical skills is emphasised throughout the text. It is only through using classification schemes that a deep understanding of their structure and unique features can be gained. Although all the major schemes covered in the text are available an the Web, it is recommended that hard-copy versions are used by those wishing to become acquainted with their overall structure. Recommended readings are supplied at the end of each chapter and provide useful sources of additional information and detail. Classification demands precision and the application of analytical skills, working carefully through the examples and the practical exercises should help readers to improve these faculties. Anyone who enjoys cryptic crosswords should recognise a parallel: classification often involves taking the meaning of something apart and then reassembling it in a different way.

Footnote

- Similarly, there is very little space provided to the thorny issue of subject analysis, which is at the conceptual core of classification work of any kind. The author's recommendations are practical, and do not address the subjective nature of this activity, nor the fundamental issues of how the classification schemes are interpreted and applied in diverse contexts, especially with respect to what a work "is about." - Finally, there is very little about practical problem solving - stories from the trenches as it were. How does a classifier choose one option over another when both seem plausible, even given that he or she has done a user and task analysis? How do classifiers respond to rapid or seemingly impulsive change? How do we evaluate the products of our work? How do we know what is the "correct" solution, even if we work, as most of us do, assuming that this is an elusive goal, but we try our best anyway? The least satisfying section of the book is the last, where the author proposes some approaches to organizing electronic resources. The suggestions seem to be to more or less transpose and adapt skills and procedures from the world of organizing books an shelves to the virtual hyperlinked world of the Web. For example, the author states (p. 153-54): Precise classification of documents is perhaps not as crucial in the electronic environment as it is in the traditional library environment. A single document can be linked to and retrieved via several different categories to allow for individual needs and expertise. However, it is not good practice to overload the system with links because that will affect its use. Effort must be made to ensure that inappropriate or redundant links are not included. The point is well taken: too muck irrelevant information is not helpful. At the same time an important point concerning the electronic environment has been overlooked as well: redundancy is what relieves the user from making precise queries or knowing the "right" place for launching a search, and redundancy is what is so natural an the Web. These are small objections, however. Overall the book is a carefully crafted primer that gives the student a strong foundation an which to build further understanding. There are well-chosen and accessible references for further reading. I world recommend it to any instructor as an excellent starting place for deeper analysis in the classroom and to any student as an accompanying text to the schedules themselves."
