- Abstract
- Currently, a number of efforts are being carried out to integrate collections from different institutions and containing heterogeneous material. Examples of such projects are The European Library [1] and the Memory of the Netherlands [2]. A crucial point for the success of these is the availability to provide a unified access on top of the different collections, e.g. using one single vocabulary for querying or browsing the objects they contain. This is made difficult by the fact that the objects from different collections are often described using different vocabularies - thesauri, classification schemes - and are therefore not interoperable at the semantic level. To solve this problem, one can turn to semantic links - mappings - between the elements of the different vocabularies. If one knows that a concept C from a vocabulary V is semantically equivalent to a concept to a concept D from vocabulary W, then an appropriate search engine can return all the objects that were indexed against D for a query for objects described using C. We thus have an access to other collections, using a single one vocabulary. This is however an ideal situation, and hard alignment work is required to reach it. Several projects in the past have tried to implement such a solution, like MACS [3] and Renardus [4]. They have demonstrated very interesting results, but also highlighted the difficulty of aligning manually all the different vocabularies involved in practical cases, which sometimes contain hundreds of thousands of concepts. To alleviate this problem, a number of tools have been proposed in order to provide with candidate mappings between two input vocabularies, making alignment a (semi-) automatic task. Recently, the Semantic Web community has produced a lot of these alignment tools'. Several techniques are found, depending on the material they exploit: labels of concepts, structure of vocabularies, collection objects and external knowledge sources. Throughout our presentation, we will present a concrete heterogeneity case where alignment techniques have been applied to build a (pilot) browser, developed in the context of the STITCH project [5]. This browser enables a unified access to two collections of illuminated manuscripts, using the description vocabulary used in the first collection, Mandragore [6], or the one used by the second, Iconclass [7]. In our talk, we will also make the point for using unified representations the vocabulary semantic and lexical information. Additionally to ease the use of the alignment tools that have these vocabularies as input, turning to a standard representation format helps designing applications that are more generic, like the browser we demonstrate. We give pointers to SKOS [8], an open and web-enabled format currently developed by the Semantic Web community.

Bertram): "Wie aus dem Titel der Publikation hervorgeht, will der Autor eine Bestandsaufnahme zum Einsatz semantischer Technologien im BID-Bereich (Bibliothek - Information - Dokumentation) bzw. BAM-Bereich (Bibliothek - Archiv - Museum) vornehmen. einigem Befremden, dass eines von insgesamt drei Vorwörtern für ein einschlägiges Softwareprodukt wirbt und von einer Firmenmitarbeiterin verfasst worden ist. Nach einer Skizze des gegenwärtigen Standes nationaler und europäischer Bibliothekspolitik folgen kurze Definitionen zu den beteiligten Branchen, zu semantischen Technologien und zu Precision und Recall. Die Ausführungen zu semantischen Technologien hätten durchaus gleich an den Anfang gestellt werden können, schließlich sollen sie ja das Hauptthema der vorliegenden Publikation abgeben. Zudem hätten sie konkreter, trennschärfer und ausführlicher ausfallen können. Der Autor moniert zu Recht das Fehlen einer einheitlichen Auffassung, was unter semantischen Technologien denn nun genau zu verstehen sei. Seine Definition lässt allerdings Fragen offen. So wird z.B. nicht geklärt, was besagte Technologien von den hier auch immer wieder erwähnten semantischen Tools unterscheidet. Das nachfolgende Kapitel über bibliographische Tools vereint eine Aufzählung konkreter Beispiele für Austauschformate, Dokumentationssysteme, Suchmaschinen, Informationsportale und OPACs. Im Anschluss daran stellt der Autor Methoden semantischer Anreicherung (bibliographischer) Daten vor und präsentiert Projekte im Bibliotheksbereich. Der aufzählende Charakter dieses und des vorangestellten Kapitels mag einem schnellen Überblick über die fraglichen Gegenstände dienlich sein, für eine systematische Lektüre eignen sich diese Passagen weniger. Auch wird der Bezug zu semantischen Technologien nicht durchgängig hergestellt.

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. . . .
