- Abstract
- As the World Wide Web continues to expand, it becomes increasingly difficult for users to obtain information efficiently. Because most search engines read format languages such as HTML or SGML, search results reflect formatting tags more than actual page content, which is expressed in natural language. Spinning the Semantic Web describes an exciting new type of hierarchy and standardization that will replace the current "Web of links" with a "Web of meaning." Using a flexible set of languages and tools, the Semantic Web will make all available information - display elements, metadata, services, images, and especially content - accessible. The result will be an immense repository of information accessible for a wide range of new applications. This first handbook for the Semantic Web covers, among other topics, software agents that can negotiate and collect information, markup languages that can tag many more types of information in a document, and knowledge systems that enable machines to read Web pages and determine their reliability. The truly interdisciplinary Semantic Web combines aspects of artificial intelligence, markup languages, natural language processing, information retrieval, knowledge representation, intelligent agents, and databases.

- Abstract
- This book discusses many of the key design issues for building search engines and emphazises the important role that applied mathematics can play in improving information retrieval. The authors discuss not only important data structures, algorithms, and software but also user-centered issues such as interfaces, manual indexing, and document preparation. They also present some of the current problems in information retrieval that many not be familiar to applied mathematicians and computer scientists and some of the driving computational methods (SVD, SDD) for automated conceptual indexing

- 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
- Das Semantic Web bezeichnet ein erweitertes World Wide Web (WWW), das die Bedeutung von präsentierten Inhalten in neuen standardisierten Sprachen wie RDF Schema und OWL modelliert. Diese Arbeit befasst sich mit dem Aspekt des Information Retrieval, d.h. es wird untersucht, in wie weit Methoden der Informationssuche sich auf modelliertes Wissen übertragen lassen. Die kennzeichnenden Merkmale von IR-Systemen wie vage Anfragen sowie die Unterstützung unsicheren Wissens werden im Kontext des Semantic Web behandelt. Im Fokus steht die Suche nach Fakten innerhalb einer Wissensdomäne, die entweder explizit modelliert sind oder implizit durch die Anwendung von Inferenz abgeleitet werden können. Aufbauend auf der an der Universität Duisburg-Essen entwickelten Retrievalmaschine PIRE wird die Anwendung unsicherer Inferenz mit probabilistischer Prädikatenlogik (pDatalog) implementiert.

- Abstract
- The main purpose of this book is to sum up the vital and highly topical research issue of knowledge representation on the Web and to discuss novel solutions by combining benefits of folksonomies and Web 2.0 approaches with ontologies and semantic technologies. This book contains an overview of knowledge representation approaches in past, present and future, introduction to ontologies, Web indexing and in first case the novel approaches of developing ontologies. This title combines aspects of knowledge representation for both the Semantic Web (ontologies) and the Web 2.0 (folksonomies). Currently there is no monographic book which provides a combined overview over these topics. focus on the topic of using knowledge representation methods for document indexing purposes. For this purpose, considerations from classical librarian interests in knowledge representation (thesauri, classification schemes etc.) are included, which are not part of most other books which have a stronger background in computer science.

- Rez. in: iwp 62(2011) H.4, S.205-206 (C. Carstens): "Welche Arten der Wissensrepräsentation existieren im Web, wie ausgeprägt sind semantische Strukturen in diesem Kontext, und wie können soziale Aktivitäten im Sinne des Web 2.0 zur Strukturierung von Wissen im Web beitragen? Diesen Fragen widmet sich Wellers Buch mit dem Titel Knowledge Representation in the Social Semantic Web. Der Begriff Social Semantic Web spielt einerseits auf die semantische Strukturierung von Daten im Sinne des Semantic Web an und deutet andererseits auf die zunehmend kollaborative Inhaltserstellung im Social Web hin. Weller greift die Entwicklungen in diesen beiden Bereichen auf und beleuchtet die Möglichkeiten und Herausforderungen, die aus der Kombination der Aktivitäten im Semantic Web und im Social Web entstehen. Der Fokus des Buches liegt dabei primär auf den konzeptuellen Herausforderungen, die sich in diesem Kontext ergeben. So strebt die originäre Vision des Semantic Web die Annotation aller Webinhalte mit ausdrucksstarken, hochformalisierten Ontologien an. Im Social Web hingegen werden große Mengen an Daten von Nutzern erstellt, die häufig mithilfe von unkontrollierten Tags in Folksonomies annotiert werden. Weller sieht in derartigen kollaborativ erstellten Inhalten und Annotationen großes Potenzial für die semantische Indexierung, eine wichtige Voraussetzung für das Retrieval im Web. Das Hauptinteresse des Buches besteht daher darin, eine Brücke zwischen den Wissensrepräsentations-Methoden im Social Web und im Semantic Web zu schlagen. Um dieser Fragestellung nachzugehen, gliedert sich das Buch in drei Teile. . . .
Insgesamt besticht das Buch insbesondere durch seine breite Sichtweise, die Aktualität und die Fülle an Referenzen. Es ist somit sowohl als Überblickswerk geeignet, das umfassend über aktuelle Entwicklungen und Trends der Wissensrepräsentation im Semantic und Social Web informiert, als auch als Lektüre für Experten, für die es vor allem als kontextualisierte und sehr aktuelle Sammlung von Referenzen eine wertvolle Ressource darstellt."

- Abstract
- Mit sozialen Suchdiensten - wie z. B. Yahoo Clever, Lycos iQ oder Mister Wong - ist eine Ergänzung und teilweise sogar eine Konkurrenz zu den bisherigen Ansätzen in der Web-Suche entstanden. Während Google und Co. automatisch generierte Trefferlisten bieten, binden soziale Suchdienste die Anwender zu Generierung der Suchergebnisse in den Suchprozess ein. Vor diesem Hintergrund wird in diesem Buch der Frage nachgegangen, inwieweit soziale Suchdienste mit traditionellen Suchmaschinen konkurrieren oder diese qualitativ ergänzen können. Der vorliegende Band beleuchtet die hier aufgeworfene Fragestellung aus verschiedenen Perspektiven, um auf die Bedeutung von sozialen Suchdiensten zu schließen.
- Issue
- Ergebnisse des Fachprojektes "Einbindung von Frage-Antwort-Diensten in die Web-Suche" am Department Information der Hochschule für Angewandte Wissenschaften Hamburg (WS 2007/2008).

- Abstract
- Das World Wide Web unterscheidet sich strukturell erheblich von den traditionellen Medien und hat das Mediensystem von Grund auf verändert. Radikal sind die Auswirkungen der webtechnischen Innovation sowohl für die Medienlandschaft und die Gesellschaft als auch für diejenigen Wissenschaften, die sich mit Medien - deren Geschichte, Inhalten, Formen, Technik, Wirkungen usf. - befassen. In dieser Einführung werden vor diesem Hintergrund einerseits Forschungsfragen einer zukünftigen Webwissenschaft auf einer übergeordneten Ebene diskutiert, andererseits werden die Perspektiven der relevanten Bezugswissenschaften integriert.

- Abstract
- Dem neuen Web mal auf die Finger geschaut -- Tom Alby hat sich bereits mit seinem Suchmaschinenoptimierung-Buch einen Namen gemacht und setzt dem Erfolg seines ersten Buches nun mit Web 2.0. Konzepte, Anwendungen, Technologien noch einen drauf. Wie schon bei der Optimierung für Suchmaschinen geht er auch bei seinem Blick auf das Phänomen Web 2.0 ganzheitlich und umfassend an die Arbeit: Ideen, Technik, Umsetzungen, Beispiele, Erfolge, Probleme, Ausblicke und Interviews mit den Machern. Ein Blitzlichtfoto im dunklen Web-Dschungel. Endlich geht es dem Web wieder gut. Alle freuen sich. Die Verlierer werden die Sieger sein. Jetzt wird alles anders. Das Blablabla in den Medien klingt ähnlich wie schon zu Zeiten des Web 1.0. Und doch ist es anders. Was sich geändert hat, zeigt sich jedoch meist erst auf den zweiten Blick -- Alby hat diese Einblicke zusammen getragen und zeigt den aktuellen Stand. Ohne Wortblasen, an Beispielen mit Hintergrund. Nach einem Blick auf die Historie von der New Economy zum Web 2.0 stürzt sich Alby auf das bekannteste Web 2.0-Beispiel: den Blog. Alsdann durchleuchtet er Podcasts, Social Software wie FlickR oder Skype, Folksonomy (wo bleibt das Geld), die Plattformrepräsentanten wie Google, die Technik im Hintergrund von AJAX bis Ruby, Business-Modelle und der Blick Richtung 3.0. Zuletzt dann Interviews mit den Vorreitern der Szene: von Johnny Haeusler bis Jörg Petermann. In Web 2.0. Konzepte, Anwendungen, Technologienkann man pieksen wie man will, es platzt nicht. Das fundierte Über- und Einblicksbuch ist jedem Journalisten, Manager, Trendforscher und Webaktivisten zu empfehlen, denn wer nicht weiß, was Alby weiß, sollte zum Thema Web 2.0 lieber schweigen.

- Rez. in: Mitt VÖB 60(2007) H.3, S.85-86 (M. Buzinkay): "Ein aktuelles Thema der Informationsbranche ist Web 2.0. Für die einen Hype, für andere Web-Realität, ist das Web 2.0 seit wenigen Jahren das "neue Web". Der Autor, Tom Alby, versucht daher im ersten Kapitel auch einen Unterschied zum Vorgänger-Web aufzubauen: Was ist so anders im Web 2.0? In weiterer Folge handelt Alby alle Themen ab, die mit Web 2.0 in Verbindung gebracht werden: Blogging, Podcasting, Social Software, Folksonomies, das Web als Plattform und diverse Web 2.0 typische Technologien. Ein Ausblick auf das Web 3.0 darf auch nicht fehlen. Das Buch liefert hier die notwendigen Einführungen und "Brücken", um auch als Laie zumindest ansatzweise Verständnis für diese neuen Entwicklungen aufzubringen. Daher ist es nur konsequent und sehr passend, dass Alby neben seinem technischen Fachjargon auch leicht verständliche Einführungsbeispiele bereithält. Denn es geht Alby weniger um Technologie und Tools (diese werden aber auch behandelt, eben beispielhaft), sondern vor allem um Konzepte: Was will das Web 2.0 überhaupt und was macht seinen Erfolg aus? Das Buch ist einfach zu lesen, mit zahlreichen Illustrationen bebildert und listet eine Unmenge an online Quellen für eine weitere Vertiefung auf. Doch mit Büchern über das Web ist es genauso wie dem Web selbst: die Halbwertszeit ist sehr kurz. Das gilt insbesondere für die Technik und für mögliche Dienste. Alby hat diesen technischen Zweig der Web 2.0-Geschichte so umfangreich wie für das Verständnis nötig, aus Gründen der Aktualität aber so gering wie möglich ausfallen lassen. Und das ist gut so: dieses Buch können Sie getrost auch in drei Jahren in die Hand nehmen. Es wird zwar andere Dienste geben als im Buch angegeben, und manche Links werden vielleicht nicht mehr funktionieren, die Prinzipien des Web 2.0 bleiben aber dieselben. Sollten Sie sich geändert haben, dann haben wir schon Web 2.x oder gar Web 3.0. Aber das ist eine andere Geschichte, die uns vielleicht Tom Alby zur angemessenen Zeit weitergeben möchte. Ein Bonus, wie ich finde, sind die zahlreichen Interviews, die Tom Alby mit bekannten deutschen Web 2.0 Aushängeschildern geführt hat. Sie geben einen guten Einblick, welchen Stellenwert Web 2.0 in der Zwischenzeit gewonnen hat. Nicht nur in einer Nische von Web-Freaks, sondern in der Welt der Kommunikation. Und das sind wir."

- Abstract
- Das 12. Internationale Symposium für Informationswissenschaft (ISI) greift unter dem Tagungsmotto "Information und Wissen: global, sozial und frei?" zentrale informationswissenschaftliche und informationspraktische Fragestellungen auf und stellt sie in einen aktuellen, wissenschaftlichen und gesellschaftspolitischen Kontext. Der Fokus liegt auf Information und Wissen in einer immer stärker vernetzten, globalisierten Welt. Aspekte der Internationalisierung und Mehrsprachigkeit von Wissensprozessen, Fragen der sozialen und technischen Teilhabe und Anschlussfähigkeit sowie des Zugriffs auf Wissensbestände und deren effektiver Anwendung treten dabei in den Mittelpunkt. Es werden beispielsweise die Rolle von sozialen Netzwerken und Fragen des Zugriffs auf Information und Wissen - im Spagat zwischen Open Access und noch fragilen politischen Entscheidungen im Urheberrecht für Wissenschaft und Bildung - diskutiert. Die Beiträge in diesem Tagungsband beleuchten das Generalthema der Tagung aus vielfältigen thematischen Perspektiven und aus der Sichtweise unterschiedlicher Disziplinen. Dabei werden sowohl aktuelle Themenfelder als auch traditionelle Kernthemen der Informationswissenschaft wie Information Retrieval, Informationsverhalten, Mensch-Maschine-Interaktion sowie deren Evaluierung behandelt. Deutlich rücken auch Themen der Fachinformation bzw. der Informationsinfrastruktur in den Vordergrund.

- Rez. in: Mitt. VÖB 59(2006) H.3, S.90-93 (O. Oberhauser): "What a marvellous book! [dies vorwegnehmend als Quintessenz der folgenden Rezension und auch für den englischsprachigen Verlag gedacht]. Den drei Herausgeberinnen, die an den Universitäten von Washington (Seattle, WA), Missouri (Columbia, MO) und Western Ontario (London, Kanada) lehren, ist das seltene Kunststück geglückt, einen Band zu erstellen, der nicht nur als mustergültige Einführung in die Thematik human information behaviour zu dienen vermag, sondern gleichzeitig auch als Nachschlagewerk zu den vielfältigen theoretischen Ansätzen innerhalb dieser bedeutenden Teildisziplin der Informationswissenschaft herangezogen werden kann. Wie sie selbst in der Danksagung feststellen, ist das Buch "a collaborative work of the information behavior community" (S. xvii), wobei die editorische Leistung vor allem darin lag, 85 Beitragende aus zehn Ländern zu koordinieren bzw. zur Abfassung von 72 Artikeln von jeweils ähnlicher Länge (bzw. Knappheit und Kürze), Gestaltung und Lesbarkeit zu veranlassen. Unter diesen 85 Beitragenden ist im übrigen alles versammelt, was in dieser Teildisziplin Rang und Namen hat, mit Ausnahme der leider bereits verstorbenen Soziologin Elfreda A. Chatman, einer der einflussreichsten Theoretikerinnen im Bereich des Informationsverhaltens, deren Andenken das Buch auch gewidmet ist.
Im Gegensatz zur früher üblichen Praxis, Informationsverhalten auf die Aktivitäten der Informationssuche zu beschränken, folgt man heute Tom Wilsons Definition, wonach es sich dabei um "the totality of human behaviour in relation to sources and channels of information, including both active and passive information-seeking, and information use" handelt, bzw. jener von Karen Pettigrew [nunmehr Fisher] et al., "how people need, seek, give and use information in different contexts". Im Laufe der letzten Jahre, ja schon Jahrzehnte, hat sich dazu ein fast nicht mehr überschaubarer Bestand an Literatur angesammelt, der sich sowohl aus theoretischen bzw. theoretisierenden, als auch aus auch praktischen bzw. empirischen Arbeiten zusammensetzt. Einige wenige dieser theoretischen Ansätze haben weite Verbreitung gefunden, werden in Studiengängen der Informationswissenschaft gelehrt und tauchen in der laufend veröffentlichten Literatur immer wieder als Basis für empirische Untersuchungen oder modifizierende Weiterentwicklungen auf. Das Buch beginnt mit drei Grundsatzartikeln, die von herausragenden Vertretern des gegenständlichen Themenbereichs verfasst wurden. Im ersten und längsten dieser Beiträge, An Introduction to Metatheories, Theories and Models (S. 1-24), gibt Marcia J. Bates (Los Angeles, CA), zunächst eine wissenschaftstheoretische Einführung zu den drei im Titel genannten Begriffen, nicht ohne darauf hinzuweisen, dass der Großteil der theoretisierenden Ansätze in unserer Disziplin erst dem Modellstadium angehört. Am Beispiel des Principle of Least Effort zeigt sie, dass selbst für diesen am besten abgesicherten Befund der Forschung zum Informationsverhalten, keine ausreichende theoretische Begründung existiert. In der Folge versucht Bates, die in der Informationswissenschaft gängigen Metatheorien zu identifizieren und gelangt dabei zu der folgenden Kategorisierung, die auch als Bezugsrahmen für die Einordnung der zahlreichen in diesem Buch dargestellten Modelle dienen kann:
1. historisch (die Gegenwart aus der Vergangheit heraus verstehen) 2. konstruktivistisch (Individuen konstruieren unter dem Einfluss ihres sozialen Kontexts das Verständnis ihrer Welten) 3. diskursanalytisch (Sprache konstituiert die Konstruktion der Identität und die Ausbildung von Bedeutungen) 4. philosophisch-analytisch (rigorose Analyse von Begriffen und Thesen) 5. kritische Theorie (Analyse versteckter Macht- und Herrschaftsmuster) 6. ethnographisch (Verständnis von Menschen durch Hineinversetzen in deren Kulturen) 7. sozialkognitiv (sowohl das Denken des Individuums als auch dessen sozialer bzw. fachlicher Umraum beeinflussen die Informationsnutzung) 8. kognitiv (Fokus auf das Denken der Individuen im Zusammenhang mit Suche, Auffindung und Nutzung von Information) 9. bibliometrisch (statistische Eigenschaften von Information) 10. physikalisch (Signalübertragung, Informationstheorie) 11. technisch (Informationsbedürfnisse durch immer bessere Systeme und Dienste erfüllen) 12. benutzerorientierte Gestaltung ("usability", Mensch-Maschine-Interaktion) 13. evolutionär (Anwendung von Ergebnissen von Biologie und Evolutionspsychologie auf informationsbezogene Phänomene). Bates Beitrag ist, wie stets, wohldurchdacht, didaktisch gut aufbereitet und in klarer Sprache abgefasst, sodass man ihn mit Freude und Gewinn liest. Zu letzterem trägt auch noch die umfangreiche Liste von Literaturangaben bei, mit der sich insbesondere die 13 genannten Metatheorien optimal weiterverfolgen lassen. . . .
Zusammenfassend möchte ich folgende Behauptung wagen: Wer dieses Buch gründlich studiert (und natürlich auch die zahlreichen Literaturhinweise verfolgt), kennt mehr oder weniger alles, was es zum Themenbereich Informationsverhalten - als Teildisziplin der Informationswissenschaft - zu wissen gibt. Kann man über ein Buch noch etwas Besseres sagen? Und kann man voraussehen, welche neuen metatheoretischen Ansätze mit einer solchen Gesamtschau noch gefunden können und werden? In formaler Hinsicht bietet der Verlag Information Today mit dem vorliegenden Buch einen ansprechend gestalteten Hardcover-Band ohne größere Mängel und mit einem dem Gebotenen angemessenen Preis. Von dem fast 30 Seiten langen kombinierten Namens- und Sachregister könnten manche europäischen Verlage - die diesbezüglich eher auf Einsparung setzen oder wenig professionelle Register anbieten - lernen, wie man derlei macht. Als fehlend könnte man vielleicht einen Anhang mit den Kurzbiographien aller Beitragenden empfinden, doch mag es verständlich erscheinen, dass dies angesichts deren großer Zahl auf eine Vorstellung der drei Herausgeberinnen beschränkt wurde. Nicht gefallen hat mir der wenig konsistente Zitierstil bei den bibliographischen Angaben, einschließlich der Mode, beim Zitieren von Zeitschriftenaufsätzen vorgeblich redundante Heftangaben wegzulassen. Über die Exaltation der dritten Herausgeberin, ihrem Vornamen (auch auf dem Titelblatt!) noch den Klammerausdruck "(E. F.)" hinzuzufügen, sei rasch der Mantel des Schweigens gebreitet. In Summe daher, wie schon eingangs festgestellt wurde, ein vorzügliches und sehr empfehlenswertes Buch."
Weitere Rez. in: JASIST 58(2007) no.2, S.303 (D.E. Agosto): "Due to the brevity of the entries, they serve more as introductions to a wide array of theories than as deep explorations of a select few. The individual entries are not as deep as those in more traditional reference volumes, such as The Encyclopedia of Library and Information Science (Drake, 2003) or The Annual Review of Information Science and Technology (ARIST) (Cronin, 2005), but the overall coverage is much broader. This volume is probably most useful to doctoral students who are looking for theoretical frameworks for nascent research projects or to more veteran researchers interested in an introductory overview of information behavior research, as those already familiar with this subfield also will probably already be familiar with most of the theories presented here. Since different authors have penned each of the various entries, the writing styles vary somewhat, but on the whole, this is a readable, pithy volume that does an excellent job of encapsulating this important area of information research."

- Rez. in: MittVÖB 62(2009) H.3, S.91-92 (H. Prillinger): "Ronald Kaiser beschäftigt sich in diesem Buch mit den Technologien, die unter den Schlagworten "Web 2.0" und "Bibliothek 2.0" zur verbesserten Kommunikation und Interaktion zwischen Bibliotheken und deren Nutzerinnen eingesetzt werden können. Dabei ist der Titel ein wenig irreführend, den der Schwerpunkt des Buches liegt nicht auf "Bibliotheken", sondern auf "Web 2.0". Kaiser gibt einen guten Überblick über die technischen Möglichkeiten, die unter"Web 2.0" zusammengefasst sind, und stellt Weblogs, RSS-Feeds, Videos, Podcasts und Wikis in einer Form vor, von der sowohl Anfängerinnen als auch Personen mit Grundkenntnissen profitieren können. Bei jedem dieser Medien geht Kaiser sowohl auf die dahinter stehende Technik und Implementierung als auch auf wichtige Grundregeln der Benützung bei der Inhaltserstellung ein (z.B. 15 Tipps für attraktive Blogangebote, oder was beim Drehen eines Videos beachtet werden sollte) und ergänzt jedes Kapitel durch ein Interview, in dem ein Experte zum jeweiligen Medium Erfahrungen, Anregungen oder wichtige Überlegungen einbringt. Die Vorstellung der Web 2.0-Technologien ist gelungen, verständlich, und für Bibliotheken, die in dieser Hinsicht aktiv werden wollen, auch sehr hilfreich; nicht ganz so erfolgreich ist das Buch leider dabei, die Relevanz dieser Technologien für Bibliotheken darzustellen.
Trotz des Titels Bibliotheken im Web 2.0 Zeitalter geht Kaiser nur am Rande darauf ein, in welcher Rolle sich Bibliotheken zum derzeitigen Zeitpunkt tatsächlich befinden, auf welche Herausforderungen sie reagieren müssen, und warum es deshalb hilfreich oder gar notwendig ist, Web 2.0-Konzepte zu übernehmen und umzusetzen. Auch die erwarteten oder potenziellen Wirkungen werden leider nur sehr sparsam oder gar nicht angesprochen. Vielmehr entsteht der Eindruck, dass es sich bei "Web 2.0" um ein post factum handelt, das einfach übernommen werden muss. Auch bei der Besprechung der einzelnen Web 2.0-Medien wird die Frage nach dem Warum nie gestellt; dass die Einrichtung eines Blogs oder eines Wikis nicht die Lösung aller Probleme darstellt, sondern im Gegenteil nur sehr spezifische Wirkungen hat, wird nicht thematisiert; ebenso wenig wird nicht darauf eingegangen, welche neuen Probleme möglicherweise durch den Einsatz dieser Technologien geschaffen werden. Für mich ist das Grundproblem dieses Buches, dass Kaiser zwar sehr ausführlich auf die Bedürfnisse jener Bibliotheken eingeht, die noch keine Erfahrungen bei der technischen Umsetzung dieser Technologien haben, aber gleichzeitig beim Großteil seiner Leserinnen umfangreiche theoretische Grundkenntnisse über eben diese Technologien vorauszusetzen scheint. Das Buch wirkt daher ein wenig so, als ob ihm eine Hälfte fehlen würde, und es fehlt eben jene Hälfte, die die Relevanz und die Wirkungspotenziale dieser Technologien für Bibliotheken enthalten sollte. Eventuell wäre ein Titel wie "Web 2.0-Technologien für Bibliotheken" zutreffender und hilfreicher gewesen, um nicht einen falschen Eindruck zu erwecken. Bibliotheken, die über Relevanz und Wirkungspotenziale bereits nachgedacht haben und den Schluss gezogen haben, dass der Einsatz dieser Technologien vorteilhaft ist, finden darin nämlich durchaus brauchbare und praxisrelevante Informationen."

- 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.

- Rez. in: JASIST 58(2007) no.3, S.457-458 (A.M.A. Ahmad): "The concept of the semantic web has emerged because search engines and text-based searching are no longer adequate, as these approaches involve an extensive information retrieval process. The deployed searching and retrieving descriptors arc naturally subjective and their deployment is often restricted to the specific application domain for which the descriptors were configured. The new era of information technology imposes different kinds of requirements and challenges. Automatic extracted audiovisual features are required, as these features are more objective, domain-independent, and more native to audiovisual content. This book is a useful guide for researchers, experts, students, and practitioners; it is a very valuable reference and can lead them through their exploration and research in multimedia content and the semantic web. The book is well organized, and introduces the concept of the semantic web and multimedia content analysis to the reader through a logical sequence from standards and hypotheses through system examples, presenting relevant tools and methods. But in some chapters readers will need a good technical background to understand some of the details. Readers may attain sufficient knowledge here to start projects or research related to the book's theme; recent results and articles related to the active research area of integrating multimedia with semantic web technologies are included. This book includes full descriptions of approaches to specific problem domains such as content search, indexing, and retrieval. This book will be very useful to researchers in the multimedia content analysis field who wish to explore the benefits of emerging semantic web technologies in applying multimedia content approaches. The first part of the book covers the definition of the two basic terms multimedia content and semantic web. The Moving Picture Experts Group standards MPEG7 and MPEG21 are quoted extensively. In addition, the means of multimedia content description are elaborated upon and schematically drawn. This extensive description is introduced by authors who are actively involved in those standards and have been participating in the work of the International Organization for Standardization (ISO)/MPEG for many years. On the other hand, this results in bias against the ad hoc or nonstandard tools for multimedia description in favor of the standard approaches. This is a general book for multimedia content; more emphasis on the general multimedia description and extraction could be provided.
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.
The final part of the book discusses research in multimedia content management systems and the semantic web, and presents examples and applications for semantic multimedia analysis in search and retrieval systems. These chapters describe example systems in which current projects have been implemented, and include extensive results and real demonstrations. For example, real case scenarios such as ECommerce medical applications and Web services have been introduced. Topics in natural language, speech and image processing techniques and their application for multimedia indexing, and content-based retrieval have been elaborated upon with extensive examples and deployment methods. The editors of the book themselves provide the readers with a chapter about their latest research results on knowledge-based multimedia content indexing and retrieval. Some interesting applications for multimedia content and the semantic web are introduced. Applications that have taken advantage of the metadata provided by MPEG7 in order to realize advance-access services for multimedia content have been provided. The applications discussed in the third part of the book provide useful guidance to researchers and practitioners properly planning to implement semantic multimedia analysis techniques in new research and development projects in both academia and industry. A fourth part should be added to this book: performance measurements for integrated approaches of multimedia analysis and the semantic web. Performance of the semantic approach is a very sophisticated issue and requires extensive elaboration and effort. Measuring the semantic search is an ongoing research area; several chapters concerning performance measurement and analysis would be required to adequately cover this area and introduce it to readers."
