- 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.

- Abstract
- The development of the Semantic Web, with machine-readable content, has the potential to revolutionise the World Wide Web and its use. A Semantic Web Primer provides an introduction and guide to this emerging field, describing its key ideas, languages and technologies. Suitable for use as a textbook or for self-study by professionals, it concentrates on undergraduate-level fundamental concepts and techniques that will enable readers to proceed with building applications on their own. It includes exercises, project descriptions and annotated references to relevant online materials. A Semantic Web Primer is the only available book on the Semantic Web to include a systematic treatment of the different languages (XML, RDF, OWL and rules) and technologies (explicit metadata, ontologies and logic and interference) that are central to Semantic Web development. The book also examines such crucial related topics as ontology engineering and application scenarios. After an introductory chapter, topics covered in succeeding chapters include XML and related technologies that support semantic interoperability; RDF and RDF Schema, the standard data model for machine-processable semantics; and OWL, the W3C-approved standard for a Web ontology language more extensive than RDF Schema; rules, both monotonic and nonmonotonic, in the framework of the Semantic Web; selected application domains and how the Semantic Web would benefit them; the development of ontology-based systems; and current debates on key issues and predictions for the future.

- Rez. in: JASIST 57(2006) no.8, S.1132-1133 (H. Che): "The World Wide Web has been the main source of an important shift in the way people communicate with each other, get information, and conduct business. However, most of the current Web content is only suitable for human consumption. The main obstacle to providing better quality of service is that the meaning of Web content is not machine-accessible. The "Semantic Web" is envisioned by Tim Berners-Lee as a logical extension to the current Web that enables explicit representations of term meaning. It aims to bring the Web to its full potential via the exploration of these machine-processable metadata. To fulfill this, it pros ides some meta languages like RDF, OWL, DAML+OIL, and SHOE for expressing knowledge that has clear, unambiguous meanings. The first steps in searing the Semantic Web into the current Web are successfully underway. In the forthcoming years, these efforts still remain highly focused in the research and development community. In the next phase, the Semantic Web will respond more intelligently to user queries. The first chapter gets started with an excellent introduction to the Semantic Web vision. At first, today's Web is introduced, and problems with some current applications like search engines are also covered. Subsequently, knowledge management. business-to-consumer electronic commerce, business-to-business electronic commerce, and personal agents are used as examples to show the potential requirements for the Semantic Web. Next comes the brief description of the underpinning technologies, including metadata, ontology, logic, and agent. The differences between the Semantic Web and Artificial Intelligence are also discussed in a later subsection. In section 1.4, the famous "laser-cake" diagram is given to show a layered view of the Semantic Web. From chapter 2, the book starts addressing some of the most important technologies for constructing the Semantic Web. In chapter 2, the authors discuss XML and its related technologies such as namespaces, XPath, and XSLT. XML is a simple, very flexible text format which is often used for the exchange of a wide variety of data on the Web and elsewhere. The W3C has defined various languages on top of XML, such as RDF. Although this chapter is very well planned and written, many details are not included because of the extensiveness of the XML technologies. Many other books on XML provide more comprehensive coverage.
The next chapter introduces resource description framework (RDF) and RDF schema (RDFS). Unlike XML, RDF provides a foundation for expressing the semantics of dada: it is a standard dada model for machine-processable semantics. Resource description framework schema offers a number of modeling primitives for organizing RDF vocabularies in typed hierarchies. In addition to RDF and RDFS, a query language for RDF, i.e. RQL. is introduced. This chapter and the next chapter are two of the most important chapters in the book. Chapter 4 presents another language called Web Ontology Language (OWL). Because RDFS is quite primitive as a modeling language for the Web, more powerful languages are needed. A richer language. DAML+OIL, is thus proposed as a joint endeavor of the United States and Europe. OWL takes DAML+OIL as the starting point, and aims to be the standardized and broadly accepted ontology language. At the beginning of the chapter, the nontrivial relation with RDF/RDFS is discussed. Then the authors describe the various language elements of OWL in some detail. Moreover, Appendix A contains an abstract OWL syntax. which compresses OWL and makes OWL much easier to read. Chapter 5 covers both monotonic and nonmonotonic rules. Whereas the previous chapter's mainly concentrate on specializations of knowledge representation, this chapter depicts the foundation of knowledge representation and inference. Two examples are also givwn to explain monotonic and non-monotonic rules, respectively. "To get the most out of the chapter. readers had better gain a thorough understanding of predicate logic first. Chapter 6 presents several realistic application scenarios to which the Semantic Web technology can be applied. including horizontal information products at Elsevier, data integration at Audi, skill finding at Swiss Life, a think tank portal at EnerSearch, e-learning. Web services, multimedia collection indexing, online procurement, raid device interoperability. These case studies give us some real feelings about the Semantic Web.
The chapter on ontology engineering describes the development of ontology-based systems for the Web using manual and semiautomatic methods. Ontology is a concept similar to taxonomy. As stated in the introduction, ontology engineering deals with some of the methodological issues that arise when building ontologies, in particular, con-structing ontologies manually, reusing existing ontologies. and using semiautomatic methods. A medium-scale project is included at the end of the chapter. Overall the book is a nice introduction to the key components of the Semantic Web. The reading is quite pleasant, in part due to the concise layout that allows just enough content per page to facilitate readers' comprehension. Furthermore, the book provides a large number of examples, code snippets, exercises, and annotated online materials. Thus, it is very suitable for use as a textbook for undergraduates and low-grade graduates, as the authors say in the preface. However, I believe that not only students but also professionals in both academia and iudustry will benefit from the book. The authors also built an accompanying Web site for the book at http://www.semanticwebprimer.org. On the main page, there are eight tabs for each of the eight chapters. For each tabm the following sections are included: overview, example, presentations, problems and quizzes, errata, and links. These contents will greatly facilitate readers: for example, readers can open the listed links to further their readings. The vacancy of the errata sections also proves the quality of the book."

- Abstract
- This established textbook introduces the essentials of classification as used for information processing. The third edition takes account of developments that have taken place since the second edition was published in 2002. "Classification Made Simple" provides a useful gateway to more advanced works and the study of specific schemes. As an introductory text, it will be invaluable to students of information work and to anyone inside or outside the information profession who needs to understand the manner in which classification can be utilized to facilitate and enhance organisation and retrieval.

- Rez. in: Mitt. VÖB 63(2010) H.1, S.143-147 (O. Oberhauser): " ... Kommen wir zur Kritik, die in den letzten Absätzen ansatzweise schon angeklungen ist. Das Anliegen des Buches ist, wie dem ersten Satz der Einleitung zu entnehmen ist, "to simplify the initial study of classification as used for knowledge organisation and information retrieval" (p. xi). Dies ist dem Autor in den ersten Kapiteln wohl auch gelungen. Die Einführung in die beiden Grundtypen - hier facettierte, dort hierarchische Systeme - ist verständlich und für Anfänger zweifellos gut geeignet. In den folgenden Kapiteln beginnt man sich aber zu fragen, wer eigentlich die Zielgruppe des Buches sein mag. Für Anfänger wird vieles zu schwierig sein, da gerade bei den anspruchsvolleren Aspekten der Text zu oberflächlich ist, keine didaktisch befriedigende Darstellung erfolgt und gelegentlich sogar Fachkenntnisse vorausgesetzt werden. Für Praktiker aus dem Bibliothekswesen fehlt vielfach der Bezug zur alltäglichen Realität, da z.B. Probleme der Buchaufstellung allenfalls am Rande zur Sprache kommen. Hochschullehrer, die eine Lehrveranstaltung zu Klassifikationsthemen vorbereiten müssen, werden manches an dem Buch nützlich finden, vielfach aber ob der mangelnden Detailliertheit zu anderen Unterlagen greifen. So bleibt der oder die "an Fragen der Klassifikation Interessierte" - ein undefiniertes und nicht allzu häufig anzutreffendes Wesen, das aber wahrscheinlich auch existiert und hier eine Fülle von Punkten angerissen findet, die zu einer weiteren Recherche in anderen Quellen animieren. Gut gelungen sind die zahlreichen Beispiele, selbst wenn dafür nicht immer sehr glückliche Notationssysteme gewählt wurden. Auch in sprachlicher Hinsicht ist - zumindest in den Anfangskapiteln - nichts zu bemängeln. Dass die beiden letzten Kapitel eher misslungen sind, wurde bereits oben angedeutet. In den übrigen Abschnitten merkt man dem Buch ebenfalls immer wieder an, dass es in seinen Grundzügen aus der Papier- und nicht aus der Online-Zeit stammt. Dennoch will ich nicht über Gebühr lamentieren, schon deshalb, da es gar nicht so viele brauchbare Lehrbücher zu Klassifikationsthemen gibt. Und in diese letztere Kategorie gehört Hunters Text alldieweil."

- Abstract
- For its third edition this standard text on knowledge organization and retrieval has been extensively revised and restructured to accommodate the increased significance of electronic information resources. With the help of many new sections on topics such as information retrieval via the Web, metadata and managing information retrieval systems, the book explains principles relating to hybrid print-based and electronic, networked environments experienced by today's users. Part I, Information Basics, explores the nature of information and knowledge and their incorporation into documents. Part II, Records, focuses specifically on electronic databases for accessing print or electronic media. Part III, Access, explores the range of tools for accessing information resources and covers interfaces, indexing and searching languages, classification, thesauri and catalogue and bibliographic access points. Finally, Part IV, Systems, describes the contexts through which knowledge can be organized and retrieved, including OPACs, the Internet, CD-ROMs, online search services and printed indexes and documents. This book is a comprehensive and accessible introduction to knowledge organization for both undergraduate and postgraduate students of information management and information systems

- Abstract
- Organizing is such a common activity that we often do it without thinking much about it. In our daily lives we organize physical things--books on shelves, cutlery in kitchen drawers--and digital things--Web pages, MP3 files, scientific datasets. Millions of people create and browse Web sites, blog, tag, tweet, and upload and download content of all media types without thinking "I'm organizing now" or "I'm retrieving now." This book offers a framework for the theory and practice of organizing that integrates information organization (IO) and information retrieval (IR), bridging the disciplinary chasms between Library and Information Science and Computer Science, each of which views and teaches IO and IR as separate topics and in substantially different ways. It introduces the unifying concept of an Organizing System--an intentionally arranged collection of resources and the interactions they support--and then explains the key concepts and challenges in the design and deployment of Organizing Systems in many domains, including libraries, museums, business information systems, personal information management, and social computing. Intended for classroom use or as a professional reference, the book covers the activities common to all organizing systems: identifying resources to be organized; organizing resources by describing and classifying them; designing resource-based interactions; and maintaining resources and organization over time. The book is extensively annotated with disciplinary-specific notes to ground it with relevant concepts and references of library science, computing, cognitive science, law, and business.

- Rez. in: KO 50(2003) no.1, S.45-46 (L.M. Given): "In her own preface to this work, the author notes her lifelong fascination with classification and order, as well as her more recent captivation with the Internet - a place of "chaos in need of organization" (xi). Sorting out the Web examines current efforts to organize the Web and is well-informed by the author's academic and professional expertise in information organization, information retrieval, and Web development. Although the book's level and tone are particularly relevant to a student audience (or others interested in Web-based subject access at an introductory level), it will also appeal to information professionals developing subject access systems across a range of information contexts. There are six chapters in the book, each describing and analyzing one core concept related to the organization of Web content. All topics are presented in a manner ideal for newcomers to the area, with clear definitions, examples, and visuals that illustrate the principles under discussion. The first chapter provides a brief introduction to developments in information technology, including an historical overview of information services, users' needs, and libraries' responses to the Internet. Chapter two introduces metadata, including core concepts and metadata formats. Throughout this chapter the author presents a number of figures that aptly illustrate the application of metadata in HTML, SGML, and MARC record environments, and the use of metadata tools (e.g., XML, RDF). Chapter three begins with an overview of classification theory and specific schemes, but the author devotes most of the discussion to the application of classification systems in the Web environment (e.g., Dewey, LCC, UDC). Web screen captures illustrate the use of these schemes for information sources posted to sites around the world. The chapter closes with a discussion of the future of classification; this is a particularly useful section as the author presents a listing of core journal and conference venues where new approaches to Web classification are explored. In chapter four, the author extends the discussion of classification to the use of controlled vocabularies. As in the first few chapters, the author first presents core background material, including reasons to use controlled vocabularies and the differences between preand post-coordinate indexing, and then discusses the application of specific vocabularies in the Web environment (e.g., Infomine's use of LCSH). The final section of the chapter explores failure in subject searching and the limitations of controlled vocabularies for the Web. Chapter five discusses one of the most common and fast-growing topics related to subject access an the Web: search engines. The author presents a clear definition of the term that encompasses classified search lists (e.g., Yahoo) and query-based engines (e.g., Alta Vista). In addition to historical background an the development of search engines, Schwartz also examines search service types, features, results, and system performance.
The chapter concludes with an appendix of search tips that even seasoned searchers will appreciate; these tips cover the complete search process, from preparation to the examination of results. Chapter six is appropriately entitled "Around the Corner," as it provides the reader with a glimpse of the future of subject access for the Web. Text mining, visualization, machine-aided indexing, and other topics are raised here to whet the reader's appetite for what is yet to come. As the author herself notes in these final pages, librarians will likely increase the depth of their collaboration with software engineers, knowledge managers and others outside of the traditional library community, and thereby push the boundaries of subject access for the digital world. This final chapter leaves this reviewer wanting a second volume of the book, one that might explore these additional topics, as they evolve over the coming years. One characteristic of any book that addresses trends related to the Internet is how quickly the text becomes dated. However, as the author herself asserts, there are core principles related to subject analysis that stand the test of time, leaving the reader with a text that may be generalized well beyond the publication date. In this, Schwartz's text is similar to other recent publications (e.g., Jakob Nielsen's Web Usability, also published in 2001) that acknowledge the mutability of the Web, and therefore discuss core principles and issues that may be applied as the medium itself evolves. This approach to the writing makes this a useful book for those teaching in the areas of subject analysis, information retrieval and Web development for possible consideration as a course text. Although the websites used here may need to be supplemented with more current examples in the classroom, the core content of the book will be relevant for many years to come. Although one might expect that any book taking subject access as its focus world, itself, be easy to navigate, this is not always the case. In this text, however, readers will be pleased to find that no small detail in content access has been spared. The subject Index is thorough and well-crafted, and the inclusion of an exhaustive author index is particularly useful for quick reference. In addition, the table of contents includes sub-themes for each chapter, and a complete table of figures is provided. While the use of colour figures world greatly enhance the text, all black-andwhite images are clear and sharp, a notable fact given that most of the figures are screen captures of websites or database entries. In addition, the inclusion of comprehensive reference lists at the close of each chapter makes this a highly readable text for students and instructors alike; each section of the book can stand as its own "expert review" of the topic at hand. In both content and structure this text is highly recommended. It certainly meets its intended goal of providing a timely introduction to the methods and problems of subject access in the Web environment, and does so in a way that is readable, interesting and engaging."

- Abstract
- Classification is a crucial skill for all information workers involved in organizing collections, but it is a difficult concept to grasp - and is even more difficult to put into practice. Essential Classification offers full guidance an how to go about classifying a document from scratch. This much-needed text leads the novice classifier step by step through the basics of subject cataloguing, with an emphasis an practical document analysis and classification. It deals with fundamental questions of the purpose of classification in different situations, and the needs and expectations of end users. The novice is introduced to the ways in which document content can be assessed, and how this can best be expressed for translation into the language of specific indexing and classification systems. The characteristics of the major general schemes of classification are discussed, together with their suitability for different classification needs.

- Rez. in: KO 32(2005) no.1, S.47-49 (M. Hudon): "Vanda Broughton's Essential Classification is the most recent addition to a very small set of classification textbooks published over the past few years. The book's 21 chapters are based very closely an the cataloguing and classification module at the School of Library, Archive, and Information studies at University College, London. The author's main objective is clear: this is "first and foremost a book about how to classify. The emphasis throughout is an the activity of classification rather than the theory, the practical problems of the organization of collections, and the needs of the users" (p. 1). This is not a theoretical work, but a basic course in classification and classification scheme application. For this reviewer, who also teaches "Classification 101," this is also a fascinating peek into how a colleague organizes content and structures her course. "Classification is everywhere" (p. 1): the first sentence of this book is also one of the first statements in my own course, and Professor Broughton's metaphors - the supermarket, canned peas, flowers, etc. - are those that are used by our colleagues around the world. The combination of tone, writing style and content display are reader-friendly; they are in fact what make this book remarkable and what distinguishes it from more "formal" textbooks, such as The Organization of Information, the superb text written and recently updated (2004) by Professor Arlene Taylor (2nd ed. Westport, Conn.: Libraries Unlimited, 2004). Reading Essential Classification, at times, feels like being in a classroom, facing a teacher who assures you that "you don't need to worry about this at this stage" (p. 104), and reassures you that, although you now speed a long time looking for things, "you will soon speed up when you get to know the scheme better" (p. 137). This teacher uses redundancy in a productive fashion, and she is not afraid to express her own opinions ("I think that if these concepts are helpful they may be used" (p. 245); "It's annoying that LCC doesn't provide clearer instructions, but if you keep your head and take them one step at a time [i.e. the tables] they're fairly straightforward" (p. 174)). Chapters 1 to 7 present the essential theoretical concepts relating to knowledge organization and to bibliographic classification. The author is adept at making and explaining distinctions: known-item retrieval versus subject retrieval, personal versus public/shared/official classification systems, scientific versus folk classification systems, object versus aspect classification systems, semantic versus syntactic relationships, and so on. Chapters 8 and 9 discuss the practice of classification, through content analysis and subject description. A short discussion of difficult subjects, namely the treatment of unique concepts (persons, places, etc.) as subjects seems a little advanced for a beginners' class.
In Chapter 10, "Controlled indexing languages," Professor Broughton states that a classification scheme is truly a language "since it permits communication and the exchange of information" (p. 89), a Statement with which this reviewer wholly agrees. Chapter 11, however, "Word-based approaches to retrieval," moves us to a different field altogether, offering only a narrow view of the whole world of controlled indexing languages such as thesauri, and presenting disconnected discussions of alphabetical filing, form and structure of subject headings, modern developments in alphabetical subject indexing, etc. Chapters 12 and 13 focus an the Library of Congress Subject Headings (LCSH), without even a passing reference to existing subject headings lists in other languages (French RAMEAU, German SWK, etc.). If it is not surprising to see a section on subject headings in a book on classification, the two subjects being taught together in most library schools, the location of this section in the middle of this particular book is more difficult to understand. Chapter 14 brings the reader back to classification, for a discussion of essentials of classification scheme application. The following five chapters present in turn each one of the three major and currently used bibliographic classification schemes, in order of increasing complexity and difficulty of application. The Library of Congress Classification (LCC), the easiest to use, is covered in chapters 15 and 16. The Dewey Decimal Classification (DDC) deserves only a one-chapter treatment (Chapter 17), while the functionalities of the Universal Decimal Classification (UDC), which Professor Broughton knows extremely well, are described in chapters 18 and 19. Chapter 20 is a general discussion of faceted classification, on par with the first seven chapters for its theoretical content. Chapter 21, an interesting last chapter on managing classification, addresses down-to-earth matters such as the cost of classification, the need for re-classification, advantages and disadvantages of using print versions or e-versions of classification schemes, choice of classification scheme, general versus special scheme. But although the questions are interesting, the chapter provides only a very general overview of what appropriate answers might be. To facilitate reading and learning, summaries are strategically located at various places in the text, and always before switching to a related subject. Professor Broughton's choice of examples is always interesting, and sometimes even entertaining (see for example "Inside out: A brief history of underwear" (p. 71)). With many examples, however, and particularly those that appear in the five chapters an classification scheme applications, the novice reader would have benefited from more detailed explanations. On page 221, for example, "The history and social influence of the potato" results in this analysis of concepts: Potato - Sociology, and in the UDC class number: 635.21:316. What happened to the "history" aspect? Some examples are not very convincing: in Animals RT Reproduction and Art RT Reproduction (p. 102), the associative relationship is not appropriate as it is used to distinguish homographs and would do nothing to help either the indexer or the user at the retrieval stage.
Essential Classification is also an exercise book. Indeed, it contains a number of practical exercises and activities in every chapter, along with suggested answers. Unfortunately, the answers are too often provided without the justifications and explanations that students would no doubt demand. The author has taken great care to explain all technical terms in her text, but formal definitions are also gathered in an extensive 172-term Glossary; appropriately, these terms appear in bold type the first time they are used in the text. A short, very short, annotated bibliography of standard classification textbooks and of manuals for the use of major classification schemes is provided. A detailed 11-page index completes the set of learning aids which will be useful to an audience of students in their effort to grasp the basic concepts of the theory and the practice of document classification in a traditional environment. Essential Classification is a fine textbook. However, this reviewer deplores the fact that it presents only a very "traditional" view of classification, without much reference to newer environments such as the Internet where classification also manifests itself in various forms. In Essential Classification, books are always used as examples, and we have to take the author's word that traditional classification practices and tools can also be applied to other types of documents and elsewhere than in the traditional library. Vanda Broughton writes, for example, that "Subject headings can't be used for physical arrangement" (p. 101), but this is not entirely true. Subject headings can be used for physical arrangement of vertical files, for example, with each folder bearing a simple or complex heading which is then used for internal organization. And if it is true that subject headings cannot be reproduced an the spine of [physical] books (p. 93), the situation is certainly different an the World Wide Web where subject headings as metadata can be most useful in ordering a collection of hot links. The emphasis is also an the traditional paperbased, rather than an the electronic version of classification schemes, with excellent justifications of course. The reality is, however, that supporting organizations (LC, OCLC, etc.) are now providing great quality services online, and that updates are now available only in an electronic format and not anymore on paper. E-based versions of classification schemes could be safely ignored in a theoretical text, but they have to be described and explained in a textbook published in 2005. One last comment: Professor Broughton tends to use the same term, "classification" to represent the process (as in classification is grouping) and the tool (as in constructing a classification, using a classification, etc.). Even in the Glossary where classification is first well-defined as a process, and classification scheme as "a set of classes ...", the definition of classification scheme continues: "the classification consists of a vocabulary (...) and syntax..." (p. 296-297). Such an ambiguous use of the term classification seems unfortunate and unnecessarily confusing in an otherwise very good basic textbook an categorization of concepts and subjects, document organization and subject representation."

- Abstract
- This book provides a theoretical and practical explanation of the latest advancements in information retrieval and their application to existing systems. It takes a system approach, discussing all aspects of an IR system. The major difference between this book and the first edition is the addition to this text of descriptions of the automated indexing of multimedia dicuments, as items in information retrieval are now considered to be a combination of text along with graphics, audio, image and video data types. The growth of the Internet and the availability of enormous volumes of data in digital form have necessitated intense interest in techniques to assist the user in locating data
