- Abstract
- Web search engines such as Google, Yahoo! MSN/Bing, and Ask are far from the consummate Web search solution: they do not typically produce direct answers to queries but instead typically recommend a selection of related documents from the Web. We note that in more recent years, search engines have begun to provide direct answers to prose queries matching certain common templates-for example, "population of china" or "12 euro in dollars"-but again, such functionality is limited to a small subset of popular user queries. Furthermore, search engines now provide individual and focused search interfaces over images, videos, locations, news articles, books, research papers, blogs, and real-time social media-although these tools are inarguably powerful, they are limited to their respective domains. In the general case, search engines are not suitable for complex information gathering tasks requiring aggregation from multiple indexed documents: for such tasks, users must manually aggregate tidbits of pertinent information from various pages. In effect, such limitations are predicated on the lack of machine-interpretable structure in HTML-documents, which is often limited to generic markup tags mainly concerned with document renderign and linking. Most of the real content is contained in prose text which is inherently difficult for machines to interpret.

- Auch "My Space" verdeutlicht die Schattenseite des Web 2.0: In mehreren hundert Fällen ermittelt die US-Bundespolizei FBI wegen sexueller Belästigungen von Kindern und Jugendlichen. Die Plattform hat reagiert und wirbt seit dieser Woche in Fernsehspots für den verantwortungsvollen Umgang mit den eigenen Daten. Durchschlagender Erfolg ist nicht zu erwarten: So lautet ein Ratschlag an die Jugendlichen, das eigene Zugangs-Passwort den Eltern mitzuteilen - was der Empfehlung gleichkommt, das eigene Tagebuch bei den Eltern zu hinterlegen. Eine weitere Bedrohung für die Privatsphäre geht von den Konzernen aus, die diese Dienste anbieten. Die meisten sind kostenlos, sie sollen über Werbung und Partnerschaften Geld bringen. So hat der Internet-Riese Yahoo eine ganze Reihe von Web2.0-Firmen gekauft, darunter das Bilderportal "Flickr" und den Bookmark-Dienst "Del.icio.us". "My Space" gehört mittlerweile zum Imperium des Medien-Moguls Rupert Murdoch. O'Reilly warnt: "Diese Firmen werden einen enormen Einfluss auf unser aller Leben haben - und sie können ihn zum Guten wie zum Schlechten nutzen." Der Identitätsdiebstahl im Internet ist mittlerweile zu einem ernsthaften Problem geworden. Kriminelle gehen mit Daten wie Namen und Kreditkartenummern auf Betrugstour. Sie verursachten laut amtlicher Statistik allein im Jahr 2004 Schäden in Höhe von sechs Milliarden Dollar - aktuelle Schätzungen gehen von bis zu 50 Milliarden Dollar Schaden pro Jahr aus. Aber nicht nur Betrüger beuten den Datenschatz im Netz aus, auch Geheimdienste zeigen Interesse. So berichtet das Wissenschaftsmagazin New Scientist, der US-Geheimdienst National Security Agency erforsche intensiv Techniken, mit deren Hilfe die Agenten soziale Netzwerke überwachen und systematisch auswerten können. Das Interesse kommt nicht von ungefähr: Web-2.0-Dienste erfreuen sich einer großen Beliebtheit. So verzeichnet das erst vor zwei Jahren gegründete Portal "My Space" schon fast 100 Millionen Nutzer, die sich über Musik- und andere Konsumvorlieben austauschen. Besonders bei Musikern ist die Plattform beliebt: Mittlerweile sollen sich dort 400 000 Bands tummeln, die ihre Arbeit auf der Plattform vorstellen."

- Zusammenarbeit mit Bibliotheken Bereits früh setzte sich Tim Spalding für eine Zusammenarbeit mit Bibliotheken ein. Zum Eintragen von neuen Büchern in LibraryThing können zahlreiche Bibliothekskataloge ausgewählt werden, die via Z39.50 eingebunden werden - seit Oktober 2006 ist auch der GBV dabei. Im April 2007 veröffentlichte Tim Spalding mit LibraryThing for Libraries ein Reihe von Webservices, die Bibliotheken in ihre OPACs einbinden können.4 Ein Webservice ist eine Funktion, die von anderen Programmen über das Web aufgerufen werden kann und Daten zurückliefert. Bereits seit Juni 2006 können über verschiedene offene LibraryThing-Webservices unter Anderem zu einer gegebenen ISBN die Sprache und eine Liste von ISBNs anderer Auflagen und Übersetzungen ermittelt werden, die zum gleichen Werk gehören (thinglSBN). Damit setzt LibraryThing praktisch einen Teil der Functional Requirements for Bibliographic Records (FRBR) um, die in bibliothekswissenschaftlichen Fachkreisen bereits seit Anfang der 1990er diskutiert werden, aber bislang nicht so Recht ihre Umsetzung in Katalogen gefunden haben. Die Information darüber, welche Bücher zum gleichen Werk gehören, wird von der LibraryThing-Community bereitgestellt; jeder Benutzer kann einzelne Ausgaben mit einem Klick zusammenführen oder wieder trennen. Vergleiche mit dem ähnlichen Dienst xISBN von OCLC zeigen, dass sich thinglSBN und xISBN gut ergänzen, allerdings bietet LibraryThing seinen Webservice im Gegensatz zu OCLC kostenlos an. Neben Empfehlungen von verwandten Büchern ist es im Rahmen von LibraryThing for Libraries auch möglich, die von den Nutzern vergebenen Tags in den eigenen Katalog einzubinden. Ein Nachteil dabei ist allerdings die bisherige Übermacht der englischen Sprache und dass nur selbständige Titel mit ISBN berücksichtigt werden. Die VZG prüft derzeit, in welcher Form LibraryThing for Libraries am besten in GBV-Bibliotheken umgesetzt werden kann. Es spricht allerdings für jede einzelne Bibliothek nichts dagegen, schon jetzt damit zu experimentieren, wie der eigene OPAC mit zusätzlichen Links und Tags von LibraryThing aussehen könnte. Darüber hinaus können sich auch Bibliotheken mit einem eigenen Zugang als Nutzer in LibraryThing beteiligen. So stellt beispielsweise die Stadtbücherei Nordenham bereits seit Ende 2005 ihre Neuzugänge im Erwachsenenbestand in einer Sammlung bei LibraryThing ein.

- Abstract
- The book covers multimedia ontology in heritage preservation with intellectual explorations of various themes of Indian cultural heritage. The result of more than 15 years of collective research, Multimedia Ontology: Representation and Applications provides a theoretical foundation for understanding the nature of media data and the principles involved in its interpretation. The book presents a unified approach to recent advances in multimedia and explains how a multimedia ontology can fill the semantic gap between concepts and the media world. It relays real-life examples of implementations in different domains to illustrate how this gap can be filled. The book contains information that helps with building semantic, content-based search and retrieval engines and also with developing vertical application-specific search applications. It guides you in designing multimedia tools that aid in logical and conceptual organization of large amounts of multimedia data. As a practical demonstration, it showcases multimedia applications in cultural heritage preservation efforts and the creation of virtual museums. The book describes the limitations of existing ontology techniques in semantic multimedia data processing, as well as some open problems in the representations and applications of multimedia ontology. As an antidote, it introduces new ontology representation and reasoning schemes that overcome these limitations. The long, compiled efforts reflected in Multimedia Ontology: Representation and Applications are a signpost for new achievements and developments in efficiency and accessibility in the field.

- Abstract
- All the papers underwent a thorough and rigorous peer-review process. The review and selection this year was highly competitive and only papers containing significant research results, innovative methods, or novel and best practices were accepted for publication. Only 29 of 89 submissions were accepted as full papers, representing 32.5% of the total number of submissions. Additional contributions covering noteworthy and important results in special tracks or project reports were accepted, totaling 42 accepted contributions. This year's conference included two outstanding keynote speakers. Dr. Stefan Gradmann, a professor arts department of KU Leuven (Belgium) and director of university library, addressed semantic research drawing from his work with Europeana. The title of his presentation was, "Towards a Semantic Research Library: Digital Humanities Research, Europeana and the Linked Data Paradigm". Dr. Michail Salampasis, associate professor from our conference host institution, the Department of Informatics of the Alexander TEI of Thessaloniki, presented new potential, intersecting search and linked data. The title of his talk was, "Rethinking the Search Experience: What Could Professional Search Systems Do Better?"

- Abstract
- Today's semantic web deals with meaning in a very restricted sense and offers static solutions. This is adequate for many scientific, technical purposes and for business transactions requiring machine-to-machine communication, but does not answer the needs of culture. Science, technology and business are concerned primarily with the latest findings, the state of the art, i.e. the paradigm or dominant world-view of the day. In this context, history is considered non-essential because it deals with things that are out of date. By contrast, culture faces a much larger challenge, namely, to re-present changes in ways of knowing; changing meanings in different places at a given time (synchronically) and over time (diachronically). Culture is about both objects and the commentaries on them; about a cumulative body of knowledge; about collective memory and heritage. Here, history plays a central role and older does not mean less important or less relevant. Hence, a Leonardo painting that is 400 years old, or a Greek statue that is 2500 years old, typically have richer commentaries and are often more valuable than their contemporary equivalents. In this context, the science of meaning (semantics) is necessarily much more complex than semantic primitives. A semantic web in the cultural domain must enable us to trace how meaning and knowledge organisation have evolved historically in different cultures. This paper examines five issues to address this challenge: 1) different world-views (i.e. a shift from substance to function and from ontology to multiple ontologies); 2) developments in definitions and meaning; 3) distinctions between words and concepts; 4) new classes of relations; and 5) dynamic models of knowledge organisation. These issues reveal that historical dimensions of cultural diversity in knowledge organisation are also central to classification of biological diversity. New ways are proposed of visualizing knowledge using a time/space horizon to distinguish between universals and particulars. It is suggested that new visualization methods make possible a history of questions as well as of answers, thus enabling dynamic access to cultural and historical dimensions of knowledge. Unlike earlier media, which were limited to recording factual dimensions of collective memory, digital media enable us to explore theories, ways of perceiving, ways of knowing; to enter into other mindsets and world-views and thus to attain novel insights and new levels of tolerance. Some practical consequences are outlined.
