    Abstract
    Although service-oriented architectures go a long way toward providing interoperability in distributed, heterogeneous environments, managing semantic differences in such environments remains a challenge. We give an overview of the issue of semantic interoperability (integration), provide a semantic characterization of services, and discuss the role of ontologies. Then we analyze four basic models of semantic interoperability that differ in respect to their mapping between service descriptions and ontologies and in respect to where the evaluation of the integration logic is performed. We also provide some guidelines for selecting one of the possible interoperability models.

    Abstract
    By the explosion of possibilities for a ubiquitous content production, the information overload problem reaches the level of complexity which cannot be managed by traditional modelling approaches anymore. Due to their pure syntactical nature traditional information retrieval approaches did not succeed in treating content itself (i.e. its meaning, and not its representation). This leads to a very low usefulness of the results of a retrieval process for a user's task at hand. In the last ten years ontologies have been emerged from an interesting conceptualisation paradigm to a very promising (semantic) modelling technology, especially in the context of the Semantic Web. From the information retrieval point of view, ontologies enable a machine-understandable form of content description, such that the retrieval process can be driven by the meaning of the content. However, the very ambiguous nature of the retrieval process in which a user, due to the unfamiliarity with the underlying repository and/or query syntax, just approximates his information need in a query, implies a necessity to include the user in the retrieval process more actively in order to close the gap between the meaning of the content and the meaning of a user's query (i.e. his information need). This thesis lays foundation for such an ontology-based interactive retrieval process, in which the retrieval system interacts with a user in order to conceptually interpret the meaning of his query, whereas the underlying domain ontology drives the conceptualisation process. In that way the retrieval process evolves from a query evaluation process into a highly interactive cooperation between a user and the retrieval system, in which the system tries to anticipate the user's information need and to deliver the relevant content proactively. Moreover, the notion of content relevance for a user's query evolves from a content dependent artefact to the multidimensional context-dependent structure, strongly influenced by the user's preferences. This cooperation process is realized as the so-called Librarian Agent Query Refinement Process. In order to clarify the impact of an ontology on the retrieval process (regarding its complexity and quality), a set of methods and tools for different levels of content and query formalisation is developed, ranging from pure ontology-based inferencing to keyword-based querying in which semantics automatically emerges from the results. Our evaluation studies have shown that the possibilities to conceptualize a user's information need in the right manner and to interpret the retrieval results accordingly are key issues for realizing much more meaningful information retrieval systems.

    Abstract
    Dieses Whitepaper befasst sich mit der Integration semantischer Technologien in bestehende Ansätze des Information Retrieval und die damit verbundenen weitreichenden Auswirkungen auf Effizienz und Effektivität von Suche und Navigation in Dokumenten. Nach einer Einbettung in die Problematik des Wissensmanagement aus Sicht der Informationstechnik folgt ein Überblick zu den Methoden des Information Retrieval. Anschließend werden die semantischen Technologien "Wissen modellieren - Ontologie" und "Neues Wissen ableiten - Inferenz" vorgestellt. Ein Integrationsansatz wird im Folgenden diskutiert und die entstehenden Mehrwerte präsentiert. Insbesondere ergeben sich Erweiterungen hinsichtlich einer verfeinerten Suchunterstützung und einer kontextbezogenen Navigation sowie die Möglichkeiten der Auswertung von regelbasierten Zusammenhängen und einfache Integration von strukturierten Informationsquellen. Das Whitepaper schließt mit einem Ausblick auf die zukünftige Entwicklung des WWW hin zu einem Semantic Web und die damit verbundenen Implikationen für semantische Technologien.

    Abstract
    Webbasierte Informationssysteme werden heute von einer Vielzahl unterschiedlicher Organisationen angeboten, mit ganz verschiedenen Zielsetzungen. Die technischen Herausforderungen bzgl. Datenhaltung, Pflege der Informationen und Anbindung an das Internet scheinen gelöst. Das Auffinden bestimmter Informationen stellt für viele Nutzer aber dennoch eine große Herausforderung dar. Das gilt für das WWW (WorldWide Web ) als Ganzes, wie auch für viele einzelne webbasierte Informationssysteme. Grund dafür sind im Wesentlichen die nach wie vor ungenügenden Benutzungs-schnittstellen. Heutig gängige webbasierte Informationssysteme bieten Nutzern meist neben einer Navigation die Möglichkeit, Informationen durch das Absenden einer Suchanfrage zu suchen. Beide Strategien, also die Suche und die Navigation, weisen jeweils eigene Probleme in der Umsetzung auf, die es verhindern, dass Nutzer die gewünschte Information einfach auffinden können. Oftmals werden Suchanfragen unspezifisch und allgemein gehalten vorgetragen. Wird eine solche Anfrage mit einer großen Zusammenstellung von Daten beantwortet, man denke nur an Suchergebnisse von Suchmaschinen mit tausenden Treffern, und damit tausenden von Nieten, kann sich schnell Frust einstellen. Aber auch heutige Navigationen sind nicht geeignet, es dem Nutzer so einfach wie möglich zu machen. Sie beschränken sich meist auf Begriffshierarchien. Der Informationsraum wird also in Ober- und Unterklassen gegliedert und die Informationsobjekte den Ebenen zugeordnet. Eine solche Aufteilung kann für den einen sinnvoll und verständlich sein, andere aber in die Irre führen. Zudem lassen sich Begriffe nur anhand zweier Beziehungen, nämlich Ober- und Unterbegriff, strukturieren. Begriffe und Konzepte vieler Themengebiete weisen aber weitere Beziehungen auf, wie "gehört zu", "arbeitet zusammen mit", "entwickelte" um nur ein paar Beispiele zu nennen. Semantische Netze bzw. Ontologien können eine solche Verknüpfung durch die Beschreibung ebendieser Beziehungen leisten. Die Ausgangsüberlegung dieser Arbeit ist es, die Strukturierung des Informationsraums mit Hilfe einer Ontologie vorzunehmen. Diese erweiterte Strukturierung soll sowohl für die Suche als auch für die Navigation genutzt werden, um die Auffindbarkeit von Information zu verbessern. Eine Suchfunktionalität müsste sich nicht mehr nur auf eine wortbasierte Suche verlassen, sondern könnte das Beziehungsgeflecht nutzen. Die Navigation wiederum könnte die Beziehungen explizit machen und dadurch Nutzern helfen, den Informationsraum zu verstehen und dadurch einfacher zielgerichtet zu der gewünschten Information zu navigieren. Als Untersuchungsgegenstand werden in dieser Arbeit Bürgerinformationssysteme betrachtet. Die Anwendungsdomäne webbasierte Bürgerinformation ist ausreichend komplex, um daran die oben angeführten Probleme untersuchen zu können. Heutige Bürgerinformationssysteme weisen, neben anderen Problemen, genau die oben beschriebenen Schwächen auf, wie sich zeigen wird.

    Abstract
    Ontologien werden eingesetzt, um durch semantische Fundierung insbesondere für das Dokumentenretrieval eine grundlegend bessere Basis zu haben, als dies gegenwärtiger Stand der Technik ist. Vorgestellt wird eine an der FH Darmstadt entwickelte und eingesetzte Ontologie, die den Gegenstandsbereich Hochschule sowohl breit abdecken und gleichzeitig differenziert semantisch beschreiben soll. Das Problem der semantischen Suche besteht nun darin, dass sie für Informationssuchende so einfach wie bei gängigen Suchmaschinen zu nutzen sein soll, und gleichzeitig auf der Grundlage des aufwendigen Informationsmodells hochwertige Ergebnisse liefern muss. Es wird beschrieben, welche Möglichkeiten die verwendete Software K-Infinity bereitstellt und mit welchem Konzept diese Möglichkeiten für eine semantische Suche nach Dokumenten und anderen Informationseinheiten (Personen, Veranstaltungen, Projekte etc.) eingesetzt werden.

    Abstract
    Semantische Techniken zur strukturierten Erschließung von Web 2.0-Content und kollaborative Anreicherung von Web Content mit maschinenlesbaren Metadaten wachsen zum Social Semantic Web zusammen, das durch eine breite Konvergenz zwischen Social Software und Semantic Web-Technologien charakterisiert ist. Dieses Buch stellt die technischen, organisatorischen und kulturellen Veränderungen dar, die das Social Semantic Web begleiten, und hilft Entscheidungsträgern und Entwicklern, die Tragweite dieser Web-Technologie für ihr jeweiliges Unternehmen zu erkennen. Social Semantic Web: Web 2.0 - Was nun? ist quasi die 2. Auflage von Semantic Web: Wege zur vernetzten Wissensgesellschaft von 2006, in der jedoch eher die technischen Aspekte im Vordergrund standen - einiges ist seitdem im weltweiten Netz passiert, vor allem mit dem, als Web 2.0 gestempelten Ajax-User-Community-Mix in Verbindung mit dem Semantic Web wurden und werden die Karten an einigen Enden der Datenautobahn neu gemischt - dem tragen Andreas Blumauer und Tassilo Pellegrini mit einem Update ihrer Fachautorensammlung für interessierte Laien und themenfremde Experten in der passenden 2.0-Neuauflage Rechnung.
    Thematisch haben die beiden Herausgeber ihre Beitragssammlung in vier Bereiche aufgeteilt: zuerst der Einstieg ins Thema Web 2.0 mit sechs Beiträgen - die Konvergenz von Semantic Web und Web 2.0, Auswirkungen auf die Gesellschaft, Technologien und jeweils die entsprechenden Perspektiven; gute, faktenbasierte Überblicke, die das Buch auf eine solide Grundlage stellen und reichhaltiges Wissen für ansonsten meist oberflächlich geführte Diskussionen zum Thema liefern. Der zweite Themenbereich ist dann den Technologien und Methodem gewidmet: Wie sieht die Technik hinter der "Semantik" im Web aus? Wissensmodellierung, Beispiele wie die Expertensuche, Content Management Systeme oder semantische Wikis. In Teil drei werfen die Autoren dann einen Blick auf bestehende Anwendungen im aktuellen Social Semantic Web und geben einen Ausblick auf deren zukünftige Entwicklungen. Im abschließenden Teil vier schließlich geben die Autoren der drei Beiträge einen Überblick zum "Social Semantic Web" aus sozialwissenschaftlicher Perspektive. Zusammenfassungen am Anfang jedes Beitrags, gute Strukturen zusätzliche Quellen und auch die gut lesbare Länge der Beiträge - angenehme verständlich und konsumierbar. Blumauer und Pellegrini haben auch mit Social Semantic Web: Web 2.0 - Was nun? ganze Arbeit geleistet und ein breites Spektrum an Perspektiven, Meinungen und Quellen zusammengetragen - das Ergebnis ist stellenweise durchaus heterogen und nicht jeder Beitrag muss gefallen, doch das Gesamtergebnis stellt die von den Herausgebern thematisierte heterogene Welt des Social Semantic Web realistisch dar. Wer in Zukunft nicht nur "gefährliches Halbwissen" um das Web 2.0 und das Semantic Web von sich geben will, sollte Social Semantic Web: Web 2.0 - Was nun? gelesen haben!

    Abstract
    In diesem Kapitel werden Anwendungsgebiete und Ansätze für die semantische Beschreibung von Web Services behandelt. Bestehende Web Service Technologien leisten einen entscheidenden Beitrag zur Entwicklung verteilter Anwendungen dadurch, dass weithin akzeptierte Standards vorliegen, die die Kommunikation zwischen Anwendungen bestimmen und womit deren Kombination zu komplexeren Einheiten ermöglicht wird. Automatisierte Mechanismen zum Auffinden geeigneter Web Services und deren Komposition dagegen werden von bestehenden Technologien in vergleichsweise geringem Maß unterstützt. Ähnlich wie bei der Annotation statischer Daten im "Semantic Web" setzen Forschung und Industrie große Hoffnungen in die semantische Beschreibung von Web Services zur weitgehenden Automatisierung dieser Aufgaben.

    Abstract
    Ziel dieses Kapitels ist es, gemeinsame Verwendungsszenarien des Semantic Web und des Social Web zu identifizieren und zu benennen. Dabei wird ein Teilaspekt des Themengebiets im Detail betrachtet: die Nutzung von Services, die Beobachtungen des Verhaltens von Anwendern analysieren, um daraus maschinell interpretierbare Informationen zu erhalten und diese als Modelle zu organisieren. Es werden zunächst einige Eigenschaften und Unterscheidungsmerkmale von Anwenderverhalten und organisierten Modellen dargestellt. Anschließend wird der mögliche wechselseitige Nutzen von Anwenderverhalten und Modellen diskutiert. Den Abschluss bildet eine Betrachtung einiger exemplarischer Software-Services, die heute schon verwendet werden, um Anwenderverhalten in Modelle überzuführen.

    Abstract
    Im Zuge des zunehmenden Einflusses des Semantic Web und der damit einhergehenden Verknüpfung von Informationen wird die Modellierung von Ontologien immer bedeutsamer. Hiermit verbunden ist natürlich auch deren Erweiterung um Instanzen, wodurch immer größere Wissensbasen entstehen. In den letzten Jahren sind sowohl aus akademischem, als auch aus industriellem Hintergrund Programme entstanden, die Ontologie-Autoren bei ihrer Arbeit unterstützen sollen. Nach einer kleinen allgemeinen Einführung in den Ablauf des Ontologiebaus soll hier ein Überblick über einige Tools gegeben werden, die aktuell zur Verfügung stehen, ohne Anspruch auf Vollständigkeit zu erheben.

    Abstract
    Das »Semantic Web« bildet einen der wichtigsten, aktuellen Trends in der Weiterentwicklung des World Wide Web. Ehrgeizige Vision dieser nächsten Generation des WWW ist es, durch semantische Anreicherung von Information eine neue Qualität in der Bereitstellung von Inhalten und Diensten zu erreichen und vollständig neue Anwendungsmöglichkeiten für das Web zu eröffnen. Wichtige Ziele der Entwicklung des Semantic Web sind dabei die verbesserte Unterstützung von Kooperation zwischen Menschen und Computern und die intelligente Assistenz bei der Durchführung von Aufgaben in kooperativen verteilten Informationsumgebungen. Schlüssel zur Erreichung dieser Ziele sind die Anreicherung von Daten im Web mit Metadaten, welche diese Daten in einen semantischen Kontext einbetten. Diese Kontextinformation wird durch Software-Anwendungen interpretiert und zur Informationsfilterung, Verfeinerung von Anfragen und zur Bereitstellung intelligenter Assistenten verwendet. Eine große Herausforderung stellt dabei die geeignete Modellierung und Beschreibung des Kontexts dar. Diese muss eine automatische, globale Interpretation ermöglichen, ohne dass auf ein allgemeingültiges semantisches Beschreibungsschema zurückgegriffen werden kann. Die Vereinbarung eines solchen allgemeingültigen Schemas ist in einem derart umfangreichen, heterogenen und autonomen Rahmen, wie ihn das WWW darstellt, nicht möglich.

    Abstract
    Der in Kapitel B behandelte Schwerpunkt ist die Ontologie-Entwicklung. Nach der Erfassung der grundlegenden Charakteristika ontologiebasierter Wissensmodellierung stehen hier die Anforderungen bei der Erstellung einer Ontologie im Vordergrund. Dazu werden die wesentlichen diesbezüglichen Errungenschaften des sogenannten Ontology Engineering erörtert. Es werden zunächst methodologische Ansätze für den Entwicklungsprozess von Ontologien sowie für die einzelnen Aufgabengebiete entwickelter Techniken und Verfahren vorgestellt. Anschließend daran werden Design-Kriterien und ein Ansatz zur Meta-Modellierung besprochen, welche der Qualitätssicherung einer Ontologie dienen sollen. Diese Betrachtungen sollen eine Übersicht über den Erkenntnisstand des Ontology Engineering geben, womit ein wesentlicher Aspekt zur Nutzung ontologiebasierter Verfahren der Wissensmodellierung im Semantic Web abgedeckt wird. Als letzter Aspekt zur Erfassung der Charakteristika ontologiebasierter Wissensmodellierung wird in Kapitel C die Fragestellung bearbeitet, wie Ontologien in Informationssystemen eingesetzt werden können. Dazu werden zunächst die Verwendungsmöglichkeiten von Ontologien identifiziert. Dann werden Anwendungsgebiete von Ontologien vorgestellt, welche zum einen Beispiele für die aufgefundenen Einsatzmöglichkeiten darstellen und zum anderen im Hinblick auf die Untersuchung der Verwendung von Ontologien im Semantic Web grundlegende Aspekte desselben erörtern sollen. Im Anschluss daran werden die wesentlichen softwaretechnischen Herausforderungen besprochen, die sich durch die Verwendung von Ontologien in Informationssystemen ergeben. Damit wird die Erarbeitung der wesentlichen Charakteristika ontologiebasierter Verfahren der Wissensmodellierung als erstem Teil dieser Arbeit abgeschlossen.
    Basierend auf diesen Abhandlungen wird in Kapitel D die Verwendung von Ontologien im Semantic Web behandelt. Dabei ist das Semantic Web nicht als computergestützte Lösung für ein konkretes Anwendungsgebiet zu verstehen, sondern - ähnlich wie existente Web-Technologien - als eine informationstechnische Infrastruktur zur Bereitstellung und Verknüpfung von Applikationen für verschiedene Anwendungsgebiete. Die technologischen Lösungen zur Umsetzung des Semantic Web befinden sich noch in der Entwicklungsphase. Daher werden zunächst die grundlegenden Ideen der Vision des Semantic Web genauer erläutert und das antizipierte Architekturmodell zur Realisierung derselben vorgestellt, wobei insbesondere die darin angestrebte Rolle von Ontologien herausgearbeitet wird. Anschließend daran wird die formale Darstellung von Ontologien durch web-kompatible Sprachen erörtert, wodurch die Verwendung von Ontologien im Semantic Web ermöglicht werden soll. In diesem Zusammenhang sollen ferner die Beweggründe für die Verwendung von Ontologien als bedeutungsdefinierende Konstrukte im Semantic Web verdeutlicht sowie die auftretenden Herausforderungen hinsichtlich der Handhabung von Ontologien aufgezeigt werden. Dazu werden als dritter Aspekt des Kapitels entsprechende Lösungsansätze des Ontologie-Managements diskutiert. Abschließend wird auf die Implikationen für konkrete Anwendungen der Semantic Web - Technologien eingegangen, die aus der Verwendung von Ontologien im Semantic Web resultieren. Zum Abschluss der Ausführungen werden die Ergebnisse der Untersuchung zusammengefasst. Dabei soll auch eine kritische Betrachtung bezüglich der Notwendigkeit semantischer Web-Technologien sowie der Realisierbarkeit der Vision des Semantic Web vorgenommen werden.
