    Abstract
    Indexing plays a vital role in Information Retrieval. With the availability of huge volume of information, it has become necessary to index the information in such a way to make easier for the end users to find the information they want efficiently and accurately. Keyword-based indexing uses words as indexing terms. It is not capable of capturing the implicit relation among terms or the semantics of the words in the document. To eliminate this limitation, ontology-based indexing came into existence, which allows semantic based indexing to solve complex and indirect user queries. Ontologies are used for document indexing which allows semantic based information retrieval. Existing ontologies or the ones constructed from scratch are used presently for indexing. Constructing ontologies from scratch is a labor-intensive task and requires extensive domain knowledge whereas use of an existing ontology may leave some important concepts in documents un-annotated. Using multiple ontologies can overcome the problem of missing out concepts to a great extent, but it is difficult to manage (changes in ontologies over time by their developers) multiple ontologies and ontology heterogeneity also arises due to ontologies constructed by different ontology developers. One possible solution to managing multiple ontologies and build from scratch is to use modular ontologies for indexing.
    Modular ontologies are built in modular manner by combining modules from multiple relevant ontologies. Ontology heterogeneity also arises during modular ontology construction because multiple ontologies are being dealt with, during this process. Ontologies need to be aligned before using them for modular ontology construction. The existing approaches for ontology alignment compare all the concepts of each ontology to be aligned, hence not optimized in terms of time and search space utilization. A new indexing technique is proposed based on modular ontology. An efficient ontology alignment technique is proposed to solve the heterogeneity problem during the construction of modular ontology. Results are satisfactory as Precision and Recall are improved by (8%) and (10%) respectively. The value of Pearsons Correlation Coefficient for degree of similarity, time, search space requirement, precision and recall are close to 1 which shows that the results are significant. Further research can be carried out for using modular ontology based indexing technique for Multimedia Information Retrieval and Bio-Medical information retrieval.

    Abstract
    Die ständig steigende Zahl an publizierter Information in immer neuen Formen verlangt besonders von Informations- und Dokumentationseinrichtungen immer präzisere Lösungen zur Erschließung dieser Informationen und ihrer benutzerfreundlichen Aufbereitung. Besonders im derzeitigen Zeitalter der Datenbanken und Online-Kataloge ist die Kombination von verbaler und klassifikatorischer Sacherschließung gefordert, ohne dabei die Verbindung zu den älteren, vielerorts noch (zumindest zusätzlich) in Verwendung befindlichen, Zettelkatalogen zu verlieren. Weltweit ist eine Vielzahl an verschiedenen Klassifikationen im Einsatz. Die Wahl der für eine Einrichtung passenden Klassifikation ist abhängig von ihrer thematischen und informationellen Ausrichtung, der Größe und Art der Bestände und nicht zuletzt von technischen und personellen Voraussetzungen. Auf Seiten der zu wählenden Klassifikation sind die Einfachheit der Handhabung für den Bibliothekar, die Verständlichkeit für den Benutzer, die Erweiterungsfähigkeit der Klassifikation durch das Aufkommen neuer Wissensgebiete und die Einbindung in informationelle Netze mit anderen Einrichtungen von entscheidender Bedeutung. In dieser Arbeit soll die Dewey Dezimalklassifikation (DDC) hinsichtlich dieser Punkte näher beleuchtet werden. Sie ist die weltweit am häufigsten benutzte Klassifikation. Etwa 200.000 Bibliotheken in 135 Ländern erschließen ihre Bestände mit diesem System. Sie liegt derzeit bereits in der 22. ungekürzten Auflage vor und wurde bisher in 30 Sprachen übersetzt. Eine deutsche Komplettübersetzung wird im Jahre 2005 erscheinen. Trotz teils heftig geführter Standardisierungsdebatten und Plänen für die Übernahme von amerikanischen Formalerschließungsregeln herrscht in Bezug auf die Sacherschließung unter deutschen Bibliotheken wenig Einigkeit. Die DDC ist in Deutschland und anderen europäischen Ländern kaum verbreitet, sieht von Großbritannien und von der Verwendung in Bibliografien ab. Diese Arbeit geht demzufolge auf die historischen Gründe dieser Entwicklung ein und wagt einen kurzen Ausblick in die Zukunft der Dezimalklassifikation.
