Abstract

Semantic Relations and the Lexicon explores the many paradigmatic semantic relations between words, such as synonymy, antonymy and hyponymy, and their relevance to the mental organization of our vocabularies. Drawing on a century's research in linguistics, psychology, philosophy, anthropology and computer science, M. Lynne Murphy proposes a pragmatic approach to these relations. Whereas traditional approaches have claimed that paradigmatic relations are part of our lexical knowledge, Dr Murphy argues that they constitute metalinguistic knowledge, which can be derived through a single relational principle, and may also be stored as part of our extra-lexical, conceptual representations of a word. Part I shows how this approach can account for the properties of lexical relations in ways that traditional approaches cannot, and Part II examines particular relations in detail. This book will serve as an informative handbook for all linguists and cognitive scientists interested in the mental representation of vocabulary.

Footnote

The release of Stimulated Recall and Mental Models, therefore, could not have been timelier. It describes an empirical qualitative, case study research conducted by authors Lyn Henderson and Julie Tallman in which they studied the mental models of school librarians teaching K-12 students how to use electronic databases. In this research, funded by the Spencer Foundation, Henderson and Tallman studied and analyzed the mental models of their subjects, six American and four Australian school librarians, as they went about the task of teaching students one-on-one how to access and retrieve the information they needed for class assignments from electronic databases. Each librarian and student underwent a structured pre-lesson interview to ascertain their mental models (the sum of their prior learning and experiences) regarding the upcoming lesson. The lesson followed immediately and was carefully video- and audio-recorded, with the full knowledge of the librarian and her student. After the lessons, both student and librarian were interviewed with the intent of learning what each were thinking and feeling at specific points during the lesson, using the recordings as memory joggers. After the first librarian-pupil session, the student was freed but the librarian was re-studied tutoring a second learner. Again, the teacher and new student were preinterviewed, their lesson was recorded, and they were debriefed using the recordings for stimulated recall. It is important to note here the use of the recordings to create stimulated recall. Though considered a dubious practice by many respected researchers, Henderson and Tallman expend considerable time and effort in this book trying to establish the credibility of stimulated recall as a valid research tool. I find it interesting that the authors report that their realization of the value of stimulated recall was a collateral benefit of their study; they claim the original objective of their research was to analyze and compare the pre- and post-lesson mental models of the teacher-librarians (p.15). Apparently, this realization provided the inspiration for this book (pp. I & 208). Hence, its place of importance in the book's title.
This book is evidence that Henderson and Tallman were meticulous in following their established protocols and especially in their record keeping while conducting their research. There are, however, a few issues in the study's framework and methodology that are worth noting. First, although the research was conducted in two different countries - the United Slates and Australia - it is not clear from the writing if the librarian-pupil pairs of each country hailed from the same schools (making the population opportunistic) or if the sampling was indeed more randomly selected. Readers do know, though, that the librarians were free to select the students they tutored from within their respective schools. Thus, there appears to he no randomness. Second, "[t]he data collection tools and questionnaires were grounded in a [single] pilot study with a [single] teacher-Iibrarian" (p. 7). Neither the procedures used nor the data collected from the pilot study are presented to establish its reliability and validity. Therefore, readers are left with only limited confidence in the study's instrumentation. Further, it is obvious from the reading, and admitted by the researchers, that the recording equipment in open view of the study's subjects skewed the data. That is, one of the librarians tinder study confessed that were it not for the cameras, she would have completely deserted one of her lessons when encountering what she perceived to be overwhelming obstacles: a classic example of the Hawthorne Effect in research. Yet. despite these issues, researchers Henderson and Tallman make a respectable ease in this book for the validity of both mental models and stimulated recall. The mental models developed during the prelesson interviews seem remarkably accurate when observing the school librarians during the lessons. Additionally, while the librarians were able to adapt their lessons based on situations, they generally did so within their mental models of what constitutes good teachers and good teaching.
As for the value of reflecting on their teaching performance, the authors report the not-so-startling denouement that while it is easy to identify and define malpractice and to commit to changing performance errors, it is often difficult to actually implement those improvements. Essentially, what is first learned is best learned and what is most used is best used. In the end, however, the authors rightfully call for further study to be conducted by themselves and others. ETS's core ICT Literacy Assessment is not currently a mandatory college entrance examination. Neither is the advanced ICT Literacy Assessment a mandatory examination for promotion to upper level undergraduate studies. But it would be naïve not to expect some enterprising institutions of higher education to at least consider making them so in the very near future. Consequently, librarians of all stripes (public. academic, school, or others) would do well to read and study Stimulated Recall and Mental Models if they are truly committed to leading the charge on advancing information literacy in the Information Age. In this book are some valuable how-tos for instructing patrons on searching electronic databases. And some of those same principles could be applicable to other areas of information literacy instruction."

Chapter 2 (Technology and People) focuses an several theories of technological acceptance and diffusion. Unfortunately, Bruce's presentation is somewhat confusing as he moves from one theory to next, never quite connecting them into a logical sequence or coherent whole. Two theories are of particular interest to Bruce: the Theory of Diffusion of Innovations and the Theory of Planned Behavior. The Theory of Diffusion of Innovations is an "information-centric view of technology acceptance" in which technology adopters are placed in the information flows of society from which they learn about innovations and "drive innovation adoption decisions" (p. 20). The Theory of Planned Behavior maintains that the "performance of a behavior is a joint function of intentions and perceived behavioral control" (i.e., how muck control a person thinks they have) (pp. 22-23). Bruce combines these two theories to form the basis for the Technology Acceptance Model. This model posits that "an individual's acceptance of information technology is based an beliefs, attitudes, intentions, and behaviors" (p. 24). In all these theories and models echoes a recurring theme: "individual perceptions of the innovation or technology are critical" in terms of both its characteristics and its use (pp. 24-25). From these, in turn, Bruce derives a predictive theory of the role personal perceptions play in technology adoption: Personal Innovativeness of Information Technology Adoption (PIITA). Personal inventiveness is defined as "the willingness of an individual to try out any new information technology" (p. 26). In general, the PIITA theory predicts that information technology will be adopted by individuals that have a greater exposure to mass media, rely less an the evaluation of information technology by others, exhibit a greater ability to cope with uncertainty and take risks, and requires a less positive perception of an information technology prior to its adoption. Chapter 3 (A Focus an Usings) introduces the User-Centered Paradigm (UCP). The UCP is characteristic of the shift of emphasis from technology to users as the driving force behind technology and research agendas for Internet development [for a dissenting view, see Andrew Dillion's (2003) challenge to the utility of user-centerness for design guidance]. It entails the "broad acceptance of the user-oriented perspective across a range of disciplines and professional fields," such as business, education, cognitive engineering, and information science (p. 34).
The UCP's effect an business practices is focused mainly in the management and marketing areas. Marketing experienced a shift from "product-oriented operations" with its focus an "selling the products' features" and customer contact only at the point of sale toward more service-Centered business practice ("customer Jemand orientation") and the development of one-to-one customer relationships (pp. 35-36). For management, the adoption of the UCP caused a shift from "mechanistic, bureaucratic, top-down organizational structures" to "flatter, inclusive, and participative" ones (p. 37). In education, practice shifted from the teachercentered model where the "teacher is responsible for and makes all the decisions related to the learning environment" to a learnercentered model where the student is "responsible for his or her own learning" and the teacher focuses an "matching learning events to the individual skills, aptitudes, and interests of the individual learner" (pp. 38-39). Cognitive engineering saw the rise of "user-Centered design" and human factors that were concerned with applying "scientific knowledge of humans to the design of man-machine interface systems" (p. 44). The UCP had a great effect an Information Science in the "design of information systems" (p. 47). Previous to UCP's explicit proposed by Brenda Dervin and M. Nilan in 1986, systems design was dominated by the "physical of system oriented paradigm" (p. 48). The physical paradigm held a positivistic and materialistic view of technology and (passive) human interaction as exemplified by the 1953 Cranfield tests of information retrieval mechanisms. Instead, the UCP focuses an "users rather than systems" by making the perceptions of individual information users the "centerpiece consideration for information service and system design" (pp. 47-48). Bruce briefly touches an the various schools of thought within user-oriented paradigm, such as the cognitive/self studies approach with its emphasis is an an individual's knowledge structures or model of the world [e.g., Belkin (1990)], the cognitve/context studies approach that focuses an "context in explaining variations in information behavior" [e.g., Savolainen (1995) and Dervin's (1999) sensemaking], and the social constructionism/discourse analytic theory with its focus an that language, not mental/knowledge constructs, as the primary shaper of the world as a system of intersubjective meanings [e.g., Talja 1996], (pp. 53-54). Drawing from the rich tradition of user oriented research, Bruce attempts to gain a metatheoretical understanding of the Internet as a phenomena by combining Dervin's (1996) "micromoments of human usings" with the French philosopher Bruno Latour's (1999) "conception of Circulating reference" to form what 1 term the Metatheory of Circulating Usings (pp. ix, 56, 60). According to Bruce, Latour's concept is designed to bridge "the gap between mind and object" by engaging in a "succession of finely grained transformations that construct and transfer truth about the object" through a chain of "microtranslations" from "matter to form," thereby connecting mind and object (p. 56). The connection works as long as the chain remains unbroken. The nature of this chain of "information producing translations" are such that as one moves away from the object, one experiences a "reduction" of the object's "locality, particularity, materiality, multiplicity and continuity," while simultaneously gaining the "amplification" of its "compatibility, standardization, text, calculation, circulation, and relative universality" (p. 57).
Bruce begins Chapter 5 (The Users' View of the Internet) by pointing out that the Internet not only exists as a physical entity of hardware, software, and networked connectivity, but also as a mental representation or knowledge structure constructed by users based an their usings. These knowledge structures or constructs "allow people to interpret and make sense of things" by functioning as a link between the new unknown thing with known thing(s) (p. 158). The knowledge structures or using constructs are continually evolving as people use the Internet over time, and represent the user's view of the Internet. To capture the users' view of the Internet from the research literature, Bruce uses his Metatheory of Circulating Usings. He recapitulates the theory, casting it more closely to the study of Internet use than previously. Here the reduction component provides a more detailed "understanding of the individual users involved in the micromoment of Internet using" while simultaneously the amplification component increases our understanding of the "generalized construct of the Internet" (p. 158). From this point an Bruce presents a relatively detail users' view of the Internet. He starts with examining Internet usings, which is composed of three parts: using space, using literacies, and Internet space. According to Bruce, using space is a using horizon likened to a "sphere of influence," comfortable and intimate, in which an individual interacts with the Internet successfully (p. 164). It is a "composite of individual (professional nonwork) constructs of Internet utility" (p. 165). Using literacies are the groups of skills or tools that an individual must acquire for successful interaction with the Internet. These literacies serve to link the using space with the Internet space. They are usually self-taught and form individual standards of successful or satisfactory usings that can be (and often are) at odds with the standards of the information profession. Internet space is, according to Bruce, a user construct that perceives the Internet as a physical, tangible place separate from using space. Bruce concludes that the user's view of the Internet explains six "principles" (p. 173). "Internet using is proof of concept" and occurs in contexts; using space is created through using frequency, individuals use literacies to explore and utilize Internet space, Internet space "does not require proof of concept, and is often influence by the perceptions and usings of others," and "the user's view of the Internet is upbeat and optimistic" (pp. 173-175). He ends with a section describing who are the Internet stakeholders. Bruce defines them as Internet hardware/software developers, Professional users practicing their profession in both familiar and transformational ways, and individuals using the Internet "for the tasks and pleasures of everyday life" (p. 176).

Abstract

Visual Interfaces to Digital Libraries exploit the power of human vision and spatial cognition to help individuals mentally organize and electronically access and manage large and complex information spaces. They draw on progress in the field of information visualization and seek to shift the users' mental load from slow reading to faster perceptual processes such as visual pattern recognition.Based on two workshops, the book presents an introductory overview as well as a closing listing of the top ten problems in the area by the volume editors. Also included are 16 thoroughly reviewed and revised full papers organized in topical sections on visual interfaces to documents, document parts, document variants, and document usage data; visual interfaces to image and video documents; visualization of knowledge domains; cartographic interfaces to digital libraries; and a general framework.

Rez. in: JASIST 56(2005) no.13, S.1463-1464 (J. Kalbach): "Many books on information and information systems quickly become outdated due to the rapid pace at which technology changes. Musings an the "future" can feel dated already by the time of publication. Understanding Information Systems avoids this pitfall by remaining agnostic to "any specific application, time, or technology" (p. xv). There are no mentions of database capacity, bandwidth issues, or Google. Instead, the author uses a mathematical perspective-relying an numbers, equations, and quantitative logic-to explain information systems at their most abstract, fundamental level. There are 16 chapters in this book, conveniently mirroring the typical number of weeks in a university semester. Each chapter is relatively short and self-contained, accessible directly or out-of-context. However, the book progresses in a very logical manner and has an overall cumulative flow to it. Each chapter also concludes with a series of about a dozen exercises and problems. This is particularly useful for classroom settings. The first four chapters form a basis for understanding information, its organization, and its retrieval. In "Describing Information," there is a particularly good discussion of various definitions of "information." For readers without prior exposure to the slipperiness of such definitions, this presentation is certainly provocative and eye opening. The bulk of chapter two, "Representing Information," focuses an an explanation of binary representation, contrasting it to decimal and hexadecimal systems. It soon becomms clear that there is no single, "natural" representation system, and each system has advantages and disadvantages. Throughout the book, the author highlights alternative ways of thinking and approaching problems.
In "Organizing Information" various fundamental organizational schemes are compared. These include hierarchical, relational, hypertext, and random access models. Each is described initially and then expanded an by listing advantages and disadvantages. This comparative format-not found elsewhere in the book-improves access to the subject and overall understanding. The author then affords considerable space to Boolean searching in the chapter "Retrieving Information." Throughout this chapter, the intricacies and problems of pattern matching and relevance are highlighted. The author elucidates the fact that document retrieval by simple pattern matching is not the same as problem solving. Therefore, "always know the nature of the problem you are trying to solve" (p. 56). This chapter is one of the more important ones in the book, covering a large topic swiftly and concisely. Chapters 5 through 11 then delve deeper into various specific issues of information systems. The chapters an securing and concealing information are exceptionally good. Without mentioning specific technologies, Mr. Ratzan is able to clearly present fundamental aspects of information security. Principles of backup security, password management, and encryption are also discussed in some detail. The latter is illustrated with some fascinating examples, from the Navajo Code Talkers to invisible ink and others. The chapters an measuring, counting, and numbering information complement each other well. Some of the more math-centric discussions and examples are found here. "Measuring Information" begins with a brief overview of bibliometrics and then moves quickly through Lotka's law, Zipf's law, and Bradford's law. For an LIS student, exposure to these topics is invaluable. Baseball statistics and web metrics are used for illustration purposes towards the end. In "counting Information," counting devices and methods are first presented, followed by discussion of the Fibonacci sequence and golden ratio. This relatively long chapter ends with examples of the tower of Hanoi, the changes of winning the lottery, and poker odds. The bulk of "Numbering Information" centers an prime numbers and pi. This chapter reads more like something out of an arithmetic book and seems somewhat extraneous here. Three specific types of information systems are presented in the second half of the book, each afforded its own chapter. These examples are universal as not to become dated or irrelevant over time. "The Computer as an Information System" is relatively short and focuses an bits, bytes, and data compression. Considering the Internet as an information system-chapter 13-is an interesting illustration. It brings up issues of IP addressing and the "privilege-vs.-right" access issue. We are reminded that the distinction between information rights and privileges is often unclear. A highlight of this chapter is the discussion of metaphors people use to describe the Internet, derived from the author's own research. He has found that people have varying mental models of the Internet, potentially affecting its perception and subsequent use.

Das Rahmenthema der Tagung kam aufgrund des vor und nach der ISKO-Konferenz abgehaltenen "UN World Summit an an Information Society" zustande. Im Titel des Buches ist die "globale Wissensgesellschaft" freilich eher irreführend, da keiner der darin abgedruckten Beiträge zentral davon handelt. Der eine der beiden Vorträge, die den Begriff selbst im Titel anführen, beschäftigt sich mit der Konstruktion einer Taxonomie für "cultural literacy" (O'Keefe), der andere mit sogenannten "naiven Klassifikationssystemen" (Beghtol), d.h. solchen, die im Gegensatz zu "professionellen" Systemen von Personen ohne spezifisches Interesse an klassifikatorischen Fragen entwickelt wurden. Beiträge mit "multi-kulti"-Charakter behandeln etwa Fragen wie - kulturübergreifende Arbeit, etwa beim EU-Filmarchiv-Projekt Collate (Albrechtsen et al.) oder einem Projekt zur Maori-Kultur (Liew); - Mehrsprachigkeit bzw. Übersetzung, z.B. der koreanischen Dezimalklassifikation (Kwasnik & Chun), eines auf der Sears ListofSubject Headings basierenden slowenischen Schlagwortvokabulars (Zalokar), einer spanisch-englischen Schlagwortliste für Gesundheitsfragen (Rosemblat et al.); - universelle Klassifikationssysteme wie die Dewey-Dezimalklassifikation (Joan Mitchell über die DDC 22, sowie zwei weitere Beiträge) und die Internationale Dezimalklassifikation (la McIlwaine über Geographika, Nancy Williamson über Alternativ- und Komplementärmedizin in der UDC). Unter den 55 Beiträgen finden sich folgende - aus der Sicht des Rezensenten - besonders interessante thematische "Cluster": - OPAC-orientierte Beiträge, etwa über die Anforderungen bei derAutomatisierung analytisch-synthetischer Klassifikationssysteme (Slavic & Cordeiro) sowie Beiträge zu Benutzerforschung und -verhalten (Lee & Clyde; Miller); - Erschliessung und Retrieval von visuellen bzw. multimedialen Ressourcen, insbesondere mit Ausrichtung auf Thesauri (Hudin; Garcia Jimenez & De Valle Gastaminza; Rafferty & Hidderley); - Thesaurus-Standards (Dextre Clark et al.), Thesauri und Endbenutzer (Shiri & Revie); - Automatisches Klassifizieren (Vizine-Goetz & Beall mit Bezug auf die DDC; Na et al. über methodische Ansätze bei der Klassifizierung von Produktbesprechungen nach positiven bzw. negativen Gefühlsäusserungen); - Beiträge über (hierzulande) weniger bekannte Systeme wie Facettenklassifikation einschliesslich der Bliss-Klassifikation sowie der Umsetzung der Ideen von Ranganathan durch E.J. Coates (vier Vorträge), die Sachs-Klassifikation (Sachs & Smiraglia) sowie M. S. van der Walts Schema zur Klassifizierung elektronischer Dokumente in Klein- und Mittelbetrieben. Auch die übrigen Beiträge sind mehrheitlich interessant geschrieben und zeugen vom fachlichen Qualitätsstandard der ISKO-Konferenzen. Der Band kann daher bibliothekarischen bzw. informationswissenschaftlichen Ausbildungseinrichtungen sowie Bibliotheken mit Sammelinteresse für Literatur zu Klassifikationsfragen ausdrücklich empfohlen werden. Ausserdem darf der nächsten (= neunten) internationalen ISKO-Konferenz, die 2006 in Wien abgehalten werden soll, mit Interesse entgegengesehen werden.

Abstract

The relationship between a person with a question and a source of information is complex. Indexing and abstracting often fail because too much emphasis is put on the mechanics of description, and too little has been given as to what ought to be represented. Research literature suggests that inappropriate representation results in failed searches a significant number of times, perhaps even in a majority of cases. "Doing Things with Information" seeks to rectify this unfortunate situation by emphasizing methods of modeling and constructing appropriate representations of such questions and documents. Students in programs of information studies will find focal points for discussion about system design and refinement of existing systems. Librarians, scholars, and those who work within large document collections, whether paper or electronic, will find insights into the strengths and weaknesses of the access systems they use.

Footnote

The authors state that this book emerged from a proposal to do a second edition of Explorations in Indexing and Abstracting (O'Connor 1996); much of its content is the result of the authors' reaction to the reviews of this first edition and their realization for "the necessity to address some more fundamental questions". Rez. in: KO 38(2011) no.1, S.62-64 (L.F. Spiteri): "This book provides a good overview of the relationship between the document and the user; in this regard, it reinforces the importance of the clientcentred approach to the design of document representation systems. In the final chapter, the authors state: "We have offered examples of new ways to think about messages in all sorts of media and how they might be discovered, analyzed, synthesized, and generated. We brought together philosophical, scientific, and engineering notions into a fundamental model for just how we might understand doing this with information" (p. 225). The authors have certainly succeeded in highlighting the complex processes, nature, and implications of document representation systems, although, as has been seen, the novelty of some of their discussions and suggestions is sometimes limited. With further explanation, the FOC model may serve as a useful way to understand how to build document representation systems to better meet user needs."; vgl.: http://www.ergon-verlag.de/isko_ko/downloads/ko_38_2011_1e.pdf.

Abstract

As information becomes more ubiquitous and the demands that searchers have on search systems grow, there is a need to support search behaviors beyond simple lookup. Information seeking is the process or activity of attempting to obtain information in both human and technological contexts. Exploratory search describes an information-seeking problem context that is open-ended, persistent, and multifaceted, and information-seeking processes that are opportunistic, iterative, and multitactical. Exploratory searchers aim to solve complex problems and develop enhanced mental capacities. Exploratory search systems support this through symbiotic human-machine relationships that provide guidance in exploring unfamiliar information landscapes. Exploratory search has gained prominence in recent years. There is an increased interest from the information retrieval, information science, and human-computer interaction communities in moving beyond the traditional turn-taking interaction model supported by major Web search engines, and toward support for human intelligence amplification and information use. In this lecture, we introduce exploratory search, relate it to relevant extant research, outline the features of exploratory search systems, discuss the evaluation of these systems, and suggest some future directions for supporting exploratory search. Exploratory search is a new frontier in the search domain and is becoming increasingly important in shaping our future world.

Abstract

Work on relationships takes place in many communities, including, among others, data modeling, knowledge representation, natural language processing, linguistics, and information retrieval. Unfortunately, continued disciplinary splintering and specialization keeps any one person from being familiar with the full expanse of that work. By including contributions form experts in a variety of disciplines and backgrounds, this volume demonstrates both the parallels that inform work on relationships across a number of fields and the singular emphases that have yet to be fully embraced, The volume is organized into 3 parts: (1) Types of relationships (2) Relationships in knowledge representation and reasoning (3) Applications of relationships

AHUJA and SATIJA (Relevance of Ranganathan's Classification Theory in the Age of Digital Libraries) note that traditional bibliographic classification systems have been applied in the digital environment with only limited success. They find that the "inherent flexibility of electronic manipulation of documents or their surrogates should allow a more organic approach to allocation of new subjects and appropriate linkages between subject hierarchies." (p. 18). Ahija and Satija also suggest that it is necessary to shift from a "subject" focus to a "need" focus when applying classification theory in the digital environment. They find Ranganathan's framework applicable in the digital environment. Although Ranganathan's focus is "subject oriented and hence emphasise the hierarchical and linear relationships" (p. 26), his framework "can be successfully adopted with certain modifications ... in the digital environment." (p. 26). SHAH and KUMAR (Model for System Unification of Geographical Schedules (Space Isolates)) report an a plan to develop a single schedule for geographical Subdivision that could be used across all classification systems. The authors argue that this is needed in order to facilitate interoperability in the digital environment. SAN SEGUNDO MANUEL (The Representation of Knowledge as a Symbolization of Productive Electronic Information) distills different approaches and definitions of the term "representation" as it relates to representation of knowledge in the library and information science literature and field. SHARADA (Linguistic and Document Classification: Paradigmatic Merger Possibilities) suggests the development of a universal indexing language. The foundation for the universal indexing language is Chomsky's Minimalist Program and Ranganathan's analytico-synthetic classification theory; Acording to the author, based an these approaches, it "should not be a problem" (p. 62) to develop a universal indexing language.
SELVI (Knowledge Classification of Digital Information Materials with Special Reference to Clustering Technique) finds that it is essential to classify digital material since the amount of material that is becoming available is growing. Selvi suggests using automated classification to "group together those digital information materials or documents that are "most similar" (p. 65). This can be attained by using Cluster analysis methods. PRADHAN and THULASI (A Study of the Use of Classification and Indexing Systems by Web Resource Directories) compare and contrast the classificatory structures of Google, Yahoo, and Looksmart's directories and compare the directories to Dewey Decimal Classification, Library of Congress Classification and Colon Classification's classificatory structures. They find differentes between the directories' and the bibliographic classification systems' classificatory structures and principles. These differentes stem from the fact that bibliographic classification systems are used to "classify academic resources for the research community" (p. 83) and directories "aim to categorize a wider breath of information groups, entertainment, recreation, govt. information, commercial information" (p. 83). NEELAMEGHAN (Hierarchy, Hierarchical Relation and Hierarchical Arrangement) reviews the concept of hierarchy and the formation of hierarchical structures across a variety of domains. NEELAMEGHAN and PRADAD (Digitized Schemes for Subject Classification and Thesauri: Complementary Roles) demonstrate how thesaural relationships (NT, BT, and RT) can be applied to a classification scheme, the Colon Classification in this Gase. NEELAMEGHAN and ASUNDI (Metadata Framework for Describing Embodied Knowledge and Subject Content) propose to use the Generalized Facet Structure framework which is based an Ranganathan's General Theory of Knowledge Classification as a framework for describing the content of documents in a metadata element set for the representation of web documents. CHUDAMANI (Classified Catalogue as a Tool for Subject Based Information Retrieval in both Traditional and Electronic Library Environment) explains why the classified catalogue is superior to the alphabetic cata logue and argues that the same is true in the digital environment.

Footnote

Semantic web technologies are explained, and ontology representation is emphasized. There is an excellent summary of the fundamental theory behind applying a knowledge-engineering approach to vision problems. This summary represents the concept of the semantic web and multimedia content analysis. A definition of the fuzzy knowledge representation that can be used for realization in multimedia content applications has been provided, with a comprehensive analysis. The second part of the book introduces the multimedia content analysis approaches and applications. In addition, some examples of methods applicable to multimedia content analysis are presented. Multimedia content analysis is a very diverse field and concerns many other research fields at the same time; this creates strong diversity issues, as everything from low-level features (e.g., colors, DCT coefficients, motion vectors, etc.) up to the very high and semantic level (e.g., Object, Events, Tracks, etc.) are involved. The second part includes topics on structure identification (e.g., shot detection for video sequences), and object-based video indexing. These conventional analysis methods are supplemented by results on semantic multimedia analysis, including three detailed chapters on the development and use of knowledge models for automatic multimedia analysis. Starting from object-based indexing and continuing with machine learning, these three chapters are very logically organized. Because of the diversity of this research field, including several chapters of recent research results is not sufficient to cover the state of the art of multimedia. The editors of the book should write an introductory chapter about multimedia content analysis approaches, basic problems, and technical issues and challenges, and try to survey the state of the art of the field and thus introduce the field to the reader.
