- Abstract
- Research on semantic web services promises greater interoperability among software agents and web services by enabling content-based automated service discovery and interaction and by utilizing. Although this is to be based on use of shared ontologies published on the semantic web, services produced and described by different developers may well use different, perhaps partly overlapping, sets of ontologies. Interoperability will depend on ontology mappings and architectures supporting the associated translation processes. The question we ask is, does the traditional approach of introducing mediator agents to translate messages between requestors and services work in such an open environment? This article reviews some of the processing assumptions that were made in the development of the semantic web service modeling ontology OWL-S and argues that, as a practical matter, the translation function cannot always be isolated in mediators. Ontology mappings need to be published on the semantic web just as ontologies themselves are. The translation for service discovery, service process model interpretation, task negotiation, service invocation, and response interpretation may then be distributed to various places in the architecture so that translation can be done in the specific goal-oriented informational contexts of the agents performing these processes. We present arguments for assigning translation responsibility to particular agents in the cases of service invocation, response translation, and match- making.

- Abstract
- This report analyzes the methodologies used in establishing interoperability among knowledge organization systems (KOS) such as controlled vocabularies and classification schemes that present the organized interpretation of knowledge structures. The development and trends of KOS are discussed with reference to the online era and the Internet era. Selected current projects and activities addressing KOS interoperability issues are reviewed in terms of the languages and structures involved. The methodological analysis encompasses both conventional and new methods that have proven to be widely accepted, including derivation/modeling, translation/adaptation, satellite and leaf node linking, direct mapping, co-occurrence mapping, switching, linking through a temporary union list, and linking through a thesaurus server protocol. Methods used in link storage and management, as weIl as common issues regarding mapping and methodological options, are also presented. It is concluded that interoperability of KOS is an unavoidable issue and process in today's networked environment. There have been and will be many multilingual products and services, with many involving various structured systems. Results from recent efforts are encouraging.

- Abstract
- Metadata applications have evolved in time into highly structured "islands of information" about digital resources, often bearing a strong semantic interpretation. Scarcely however are these semantics being communicated in machine readable and understandable ways. At the same time, the process for transforming the implied metadata knowledge into explicit Semantic Web descriptions can be problematic and is not always evident. In this article we take upon the well-established Dublin Core metadata standard as well as other metadata schemata, which often appear in digital repositories set-ups, and suggest a proper Semantic Web OWL ontology. In this process the authors cope with discrepancies and incompatibilities, indicative of such attempts, in novel ways. Moreover, we show the potential and necessity of this approach by demonstrating inferences on the resulting ontology, instantiated with actual metadata records. The authors conclude by presenting a working prototype that provides for inference-based querying on top of digital repositories.

- Darin u.a. "Interoperabilität als Kernstück - Technische und semantische Interoperabilität bilden somit das Kernstück für das Funktionieren der Europäischen Digitalen Bibliothek. Doch bevor Wege gefunden werden können, wie etwas funktionieren kann, muss zunächst einmal festgelegt werden, was funktionieren soll. Hierfür sind die Nutzeranforderungen das Maß aller Dinge, weshalb sich ein ganzes Arbeitspaket in EDLnet mit der Nutzersicht, den Nutzeranforderungen und der Nutzbarkeit der Europäischen Digitalen Bibliothek befasst, Anforderungen formuliert und diese im Arbeitspaket »Interoperabilität« umgesetzt werden. Für die Entscheidung, welche Inhalte wie präsentiert werden, sind jedoch nicht allein technische und semantische Fragestellungen zu klären, sondern auch ein Geschäftsmodell zu entwickeln, das festlegt, was die beteiligten Institutionen und Organisationen in welcher Form zu welchen Bedingungen zur Europäischen Digitalen Bibliothek beitragen. Auch das Geschäftsmodell wird Auswirkungen auf technische und semantische Interoperabilität haben und liefert die daraus abgeleiteten Anforderungen zur Umsetzung an das entsprechende Arbeitspaket. Im EDLnet-Projekt ist somit ein ständiger Arbeitskreislauf installiert, in welchem die Anforderungen an die Europäische Digitale Bibliothek formuliert, an das Interoperabilitäts-Arbeitspaket weitergegeben und dort umgesetzt werden. Diese Lösung wird wiederum an die Arbeitspakete »Nutzersicht« und »Geschäftsmodell« zurückgemeldet, getestet, kommentiert und für die Kommentare wiederum technische Lösungen gesucht. Dies ist eine Form des »rapid prototyping«, das hier zur Anwendung kommt, d. h. die Funktionalitäten werden schrittweise gemäß des Feedbacks der zukünftigen Nutzer sowie der Projektpartner erweitert und gleichzeitig wird der Prototyp stets lauffähig gehalten und bis zur Produktreife weiterentwickelt. Hierdurch verspricht man sich ein schnelles Ergebnis bei geringem Risiko einer Fehlentwicklung durch das ständige Feedback."

- Abstract
- Aufgrund der durch die Nutzer verstärkt geforderten Zusammenführung bislang verteilt vorliegender Informationssammlungen an einer Stelle tritt in der Praxis ein Phänomen zu Tage, das mit Blick auf die einzelne Informationssammlung in vielen Fällen bereits als gelöst betrachtet wurde: Heterogenität. Es zeigt sich, dass Standardisierungsansätze oft zu kurz greifen, da sie für die praktische Anwendung keine Modelle bieten, die trotz Standardisierungsbemühungen verbleibenden Unterschiede effizient und wirksam zu behandeln. Der Artikel stellt anhand zweier Beispiele aus dem Bereich der Fachinformation Lösungswege vor, wie in der Praxis Heterogenität zwischen Informationssammlungen auf semantischer Ebene behandelt werden kann. Sie tritt immer dann auf, wenn mehrere Quellen gleichzeitig durchsucht werden sollen, diese aber mit unterschiedlichen Indexierungsvokabularen erschlossen wurden. Am Beispiel statistischer Daten für die Marktforschung und wissenschaftlicher Literaturinformationssysteme werden Lösungen vorgestellt, mit dem Erschließungsvokabulare so aufeinander abgebildet werden können, dass sie Nutzer sowohl bei der Anfrageformulierung unterstützen können als auch bei der Suche eine für den Nutzer transparente und automatische Anfragetransformation ermöglichen. Ziel dieser Verfahren ist es, die kognitive Last beim Nutzer währender der Anfrageformulierung zu verringern und den Recall von Suchen in heterogen erschlossenen Informationssammlungen zu erhöhen.
