    Abstract
    In this thesis we propose three new word association measures for multi-word term extraction. We combine these association measures with LocalMaxs algorithm in our extraction model and compare the results of different multi-word term extraction methods. Our approach is language and domain independent and requires no training data. It can be applied to such tasks as text summarization, information retrieval, and document classification. We further explore the potential of using multi-word terms as an effective representation for general web-page summarization. We extract multi-word terms from human written summaries in a large collection of web-pages, and generate the summaries by aligning document words with these multi-word terms. Our system applies machine translation technology to learn the aligning process from a training set and focuses on selecting high quality multi-word terms from human written summaries to generate suitable results for web-page summarization.

    Abstract
    While classifications are heavily used to categorize web content, the evolution of the web foresees a more formal structure - ontology - which can serve this purpose. Ontologies are core artifacts of the Semantic Web which enable machines to use inference rules to conduct automated reasoning on data. Lightweight ontologies bridge the gap between classifications and ontologies. A lightweight ontology (LO) is an ontology representing a backbone taxonomy where the concept of the child node is more specific than the concept of the parent node. Formal lightweight ontologies can be generated from their informal ones. The key applications of formal lightweight ontologies are document classification, semantic search, and data integration. However, these applications suffer from the following problems: the disambiguation accuracy of the state of the art NLP tools used in generating formal lightweight ontologies from their informal ones; the lack of background knowledge needed for the formal lightweight ontologies; and the limitation of ontology reuse. In this dissertation, we propose a novel solution to these problems in formal lightweight ontologies; namely, faceted lightweight ontology (FLO). FLO is a lightweight ontology in which terms, present in each node label, and their concepts, are available in the background knowledge (BK), which is organized as a set of facets. A facet can be defined as a distinctive property of the groups of concepts that can help in differentiating one group from another. Background knowledge can be defined as a subset of a knowledge base, such as WordNet, and often represents a specific domain.

    Abstract
    Converting UDC numbers manually to a complex format such as the one mentioned above is an unrealistic expectation; supporting building these representations, as far as possible automatically, is a well-founded requirement. An additional advantage of this approach is that the existing records could also be processed and converted. In my dissertation I would like to prove also that it is possible to design and implement an algorithm that is able to convert pre-coordinated UDC numbers into the introduced format by identifying all their elements and revealing their whole syntactic structure as well. In my dissertation I will discuss a feasible way of building a UDC-specific XML schema for describing the most detailed and complicated UDC numbers (containing not only the common auxiliary signs and numbers, but also the different types of special auxiliaries). The schema definition is available online at: http://piros.udc-interpreter.hu#xsd. The primary goal of my research is to prove that it is possible to support building, retrieving, and analyzing UDC numbers without compromises, by taking the whole syntactic richness of the scheme by storing the UDC numbers reserving the meaning of pre-coordination. The research has also included the implementation of a software that parses UDC classmarks attended to prove that such solution can be applied automatically without any additional effort or even retrospectively on existing collections.

    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
    Diese Arbeit besteht im Wesentlichen aus zwei Teilen: Der erste Teil beinhaltet eine Einführung in den Begriff Web 2.0 und in die allgemeinen Rahmenbedingungen der zugehörigen technischen Entwicklungen. Des Weiteren werden exemplarische Techniken vorgestellt, die Web 2.0 zugeschrieben werden können sowie einige beispielhafte Anwendungen. Im zweiten Teil wird die Diskussion um Bibliothek 2.0 aufgegriffen, um anschließend näher auf Web 2.0 Techniken in Bibliothekskatalogen bzw. den OPAC 2.0 einzugehen. Verschiedene Techniken, die im OPAC 2.0 Anwendung finden können, werden diskutiert und zuletzt werden einige beispielhafte OPACs vorgestellt.

    Abstract
    In der heutigen Zeit sind Informationen jeglicher Art über das World Wide Web (WWW) für eine breite Bevölkerungsschicht zugänglich. Dabei ist es jedoch schwierig die existierenden Dokumente auch so aufzubereiten, dass die Inhalte für Maschinen inhaltlich interpretierbar sind. Das Semantic Web, eine Weiterentwicklung des WWWs, möchte dies ändern, indem es Webinhalte in maschinenverständlichen Formaten anbietet. Dadurch können Automatisierungsprozesse für die Suchanfragenoptimierung und für die Wissensbasenvernetzung eingesetzt werden. Die Web Ontology Language (OWL) ist eine mögliche Sprache, in der Wissen beschrieben und gespeichert werden kann (siehe Kapitel 4 OWL). Das Softwareprodukt Protégé unterstützt den Standard OWL, weshalb ein Großteil der Modellierungsarbeiten in Protégé durchgeführt wurde. Momentan erhält der Nutzer in den meisten Fällen bei der Informationsfindung im Internet lediglich Unterstützung durch eine von Suchmaschinenbetreibern vorgenommene Verschlagwortung des Dokumentinhaltes, d.h. Dokumente können nur nach einem bestimmten Wort oder einer bestimmten Wortgruppe durchsucht werden. Die Ausgabeliste der Suchergebnisse muss dann durch den Nutzer selbst gesichtet und nach Relevanz geordnet werden. Das kann ein sehr zeit- und arbeitsintensiver Prozess sein. Genau hier kann das Semantic Web einen erheblichen Beitrag in der Informationsaufbereitung für den Nutzer leisten, da die Ausgabe der Suchergebnisse bereits einer semantischen Überprüfung und Verknüpfung unterliegt. Deshalb fallen hier nicht relevante Informationsquellen von vornherein bei der Ausgabe heraus, was das Finden von gesuchten Dokumenten und Informationen in einem bestimmten Wissensbereich beschleunigt.
    Um die Vernetzung von Daten, Informationen und Wissen imWWWzu verbessern, werden verschiedene Ansätze verfolgt. Neben dem Semantic Web mit seinen verschiedenen Ausprägungen gibt es auch andere Ideen und Konzepte, welche die Verknüpfung von Wissen unterstützen. Foren, soziale Netzwerke und Wikis sind eine Möglichkeit des Wissensaustausches. In Wikis wird Wissen in Form von Artikeln gebündelt, um es so einer breiten Masse zur Verfügung zu stellen. Hier angebotene Informationen sollten jedoch kritisch hinterfragt werden, da die Autoren der Artikel in den meisten Fällen keine Verantwortung für die dort veröffentlichten Inhalte übernehmen müssen. Ein anderer Weg Wissen zu vernetzen bietet das Web of Linked Data. Hierbei werden strukturierte Daten des WWWs durch Verweise auf andere Datenquellen miteinander verbunden. Der Nutzer wird so im Zuge der Suche auf themenverwandte und verlinkte Datenquellen verwiesen. Die geowissenschaftlichen Metadaten mit ihren Inhalten und Beziehungen untereinander, die beim GFZ unter anderem im Information System and Data Center (ISDC) gespeichert sind, sollen als Ontologie in dieser Arbeit mit den Sprachkonstrukten von OWL modelliert werden. Diese Ontologie soll die Repräsentation und Suche von ISDC-spezifischem Domänenwissen durch die semantische Vernetzung persistenter ISDC-Metadaten entscheidend verbessern. Die in dieser Arbeit aufgezeigten Modellierungsmöglichkeiten, zunächst mit der Extensible Markup Language (XML) und später mit OWL, bilden die existierenden Metadatenbestände auf einer semantischen Ebene ab (siehe Abbildung 2). Durch die definierte Nutzung der Semantik, die in OWL vorhanden ist, kann mittels Maschinen ein Mehrwert aus den Metadaten gewonnen und dem Nutzer zur Verfügung gestellt werden. Geowissenschaftliche Informationen, Daten und Wissen können in semantische Zusammenhänge gebracht und verständlich repräsentiert werden. Unterstützende Informationen können ebenfalls problemlos in die Ontologie eingebunden werden. Dazu gehören z.B. Bilder zu den im ISDC gespeicherten Instrumenten, Plattformen oder Personen. Suchanfragen bezüglich geowissenschaftlicher Phänomene können auch ohne Expertenwissen über Zusammenhänge und Begriffe gestellt und beantwortet werden. Die Informationsrecherche und -aufbereitung gewinnt an Qualität und nutzt die existierenden Ressourcen im vollen Umfang.

    Abstract
    Multimodalität ist ein typisches Merkmal der Kommunikation im Social Web. Der Fokus dieses Bandes liegt auf der Kommunikation in Foto-Communitys, insbesondere auf den beiden kommunikativen Praktiken des Social Taggings und des Verfassens von Notizen innerhalb von Bildern. Bei den Tags stehen semantische Text-Bild-Relationen im Vordergrund: Tags dienen der Wissensrepräsentation, eine adäquate Versprachlichung der Bilder ist folglich unabdingbar. Notizen-Bild-Relationen sind aus pragmatischer Perspektive von Interesse: Die Informationen eines Kommunikats werden komplementär auf Text und Bild verteilt, was sich in verschiedenen sprachlichen Phänomenen niederschlägt. Ein diachroner Vergleich mit der Postkartenkommunikation sowie ein Exkurs zur Kommunikation mit Emojis runden das Buch ab.

    Abstract
    Bibliografische Daten, Normdaten und Metadaten im Semantic Web - Konzepte der Bibliografischen Kontrolle im Wandel. Der Titel dieser Arbeit zielt in ein essentielles Feld der Bibliotheks- und Informationswissenschaft, die Bibliografische Kontrolle. Als zweites zentrales Konzept wird der in der Weiterentwicklung des World Wide Webs (WWW) bedeutsame Begriff des Semantic Webs genannt. Auf den ersten Blick handelt es sich hier um einen ungleichen Wettstreit. Auf der einen Seite die Bibliografische Kontrolle, welche die Methoden und Mittel zur Erschließung von bibliothekarischen Objekten umfasst und traditionell in Form von formal-inhaltlichen Surrogaten in Katalogen daherkommt. Auf der anderen Seite das Buzzword Semantic Web mit seinen hochtrabenden Konnotationen eines durch Selbstreferenzialität "bedeutungstragenden", wenn nicht sogar "intelligenten" Webs. Wie kamen also eine wissenschaftliche Bibliothekarin und ein Mitglied des World Wide Web Consortiums 2007 dazu, gemeinsam einen Aufsatz zu publizieren und darin zu behaupten, das semantische Netz würde ein "bibliothekarischeres" Netz sein? Um sich dieser Frage zu nähern, soll zunächst kurz die historische Entwicklung der beiden Informationssphären Bibliothek und WWW gemeinsam betrachtet werden. Denn so oft - und völlig zurecht - die informationelle Revolution durch das Internet beschworen wird, so taucht auch immer wieder das Analogon einer weltweiten, virtuellen Bibliothek auf. Genauer gesagt, nahmen die theoretischen Überlegungen, die später zur Entwicklung des Internets führen sollten, ihren Ausgangspunkt (neben Kybernetik und entstehender Computertechnik) beim Konzept des Informationsspeichers Bibliothek.

    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
    Das Aufkommen des Web 2.0 im Jahr 2004 signalisierte einen Wechsel in der Internetnutzung. Beim Web 2.0 stehen die Nutzer und deren Informationsbedürfnisse im Mittelpunkt. Dies bedeutet auch für Bibliotheken eine Herausforderung. Der Online-Katalog als zentrale Dienstleistung ist von diesen Änderungen besonders betroffen. Hersteller von Bibliothekssoftware und Bibliotheken sind mit der Tatsache konfrontiert, dass immer mehr Menschen für ihre Informationsanliegen das Internet verwenden und Bibliothekskataloge umgehen. Bibliothekarische Webseiten können oft nicht mit Oberflächen wie denen von Google oder Amazon hinsichtlich Benutzerfreundlichkeit konkurrieren. Um nicht weiter in der Wahrnehmung der Nutzer zurückzufallen müssen Bibliotheken ihre Konzepte und Angebote gründlich analysieren. Das Ziel dieser Arbeit ist es, Schwächen und Probleme von konventionellen Online-Katalogen aufzuzeigen und welche Möglichkeiten es gibt, den OPAC für Nutzer attraktiver zu gestalten. Zuerst werden Informationen zum Thema in einschlägigen Publikationen gesammelt. Im Anschluss erfolgt eine Zusammenfassung und Auswertung der erarbeiteten Literatur. Dann werden einige Hochschulbibliotheken vorgestellt, die in ihren OPACs bereits Web 2.0-Anwendungen anbieten bzw. planen. Außerdem werden qualitative Interviews mit Bibliothekaren durchgeführt, die zuständig sind für einen OPAC 2.0. Mit den in den Interviews getätigten Aussagen soll ein aktueller Stand hinsichtlich OPAC-Entwicklung bezweckt werden. Ein wesentliches Ergebnis dieser Arbeit ist, dass es den OPAC 2.0 nicht gibt, und dass jede Bibliothek spezifische Erfordernisse hat, was einen Online-Katalog anbelangt. Daher wird vorgeschlagen, dass Bibliotheken zunächst sich und ihre Arbeitsumfeld sorgfältig analysieren, insbesondere ihre Zielgruppen. Aufgrund der Tatsache, dass es viele Attribute für einen OPAC 2.0 gibt, sollten Entscheidungsträger in Bibliotheken sorgfältig abwägen, welche Instrumente und Anwendungen erforderlich und sinnvoll sind.

    Abstract
    Es steht uns eine praktisch unbegrenzte Menge an Informationen über das World Wide Web zur Verfügung. Das Problem, das daraus erwächst, ist, diese Menge zu bewältigen und an die Information zu gelangen, die im Augenblick benötigt wird. Das überwältigende Angebot zwingt sowohl professionelle Anwender als auch Laien zu suchen, ungeachtet ihrer Ansprüche an die gewünschten Informationen. Um dieses Suchen effizienter zu gestalten, gibt es einerseits die Möglichkeit, leistungsstärkere Suchmaschinen zu entwickeln. Eine andere Möglichkeit ist, Daten besser zu strukturieren, um an die darin enthaltenen Informationen zu gelangen. Hoch strukturierte Daten sind maschinell verarbeitbar, sodass ein Teil der Sucharbeit automatisiert werden kann. Das Semantic Web ist die Vision eines weiterentwickelten World Wide Web, in dem derart strukturierten Daten von so genannten Softwareagenten verarbeitet werden. Die fortschreitende inhaltliche Strukturierung von Daten wird Semantisierung genannt. Im ersten Teil der Arbeit sollen einige wichtige Methoden der inhaltlichen Strukturierung von Daten skizziert werden, um die Stellung von Ontologien innerhalb der Semantisierung zu klären. Im dritten Kapitel wird der Aufbau und die Aufgabe des CIDOC Conceptual Reference Model (CRM), einer Domain Ontologie im Bereich des Kulturerbes dargestellt. Im darauf folgenden praktischen Teil werden verschiedene Ansätze zur Verwendung des CRM diskutiert und umgesetzt. Es wird ein Vorschlag zur Implementierung des Modells in XML erarbeitet. Das ist eine Möglichkeit, die dem Datentransport dient. Außerdem wird der Entwurf einer Klassenbibliothek in Java dargelegt, auf die die Verarbeitung und Nutzung des Modells innerhalb eines Informationssystems aufbauen kann.
