Abstract

T.1: Today's thesauri are mostly electronic tools, having moved on from the paper-based era when thesaurus standards were first developed. They are built and maintained with the support of software and need to integrate with other software, such as search engines and content management systems. Whereas in the past thesauri were designed for information professionals trained in indexing and searching, today there is a demand for vocabularies that untrained users will find to be intuitive. ISO 25964 makes the transition needed for the world of electronic information management. However, part 1 retains the assumption that human intellect is usually involved in the selection of indexing terms and in the selection of search terms. If both the indexer and the searcher are guided to choose the same term for the same concept, then relevant documents will be retrieved. This is the main principle underlying thesaurus design, even though a thesaurus built for human users may also be applied in situations where computers make the choices. Efficient exchange of data is a vital component of thesaurus management and exploitation. Hence the inclusion in this standard of recommendations for exchange formats and protocols. Adoption of these will facilitate interoperability between thesaurus management systems and the other computer applications, such as indexing and retrieval systems, that will utilize the data. Thesauri are typically used in post-coordinate retrieval systems, but may also be applied to hierarchical directories, pre-coordinate indexes and classification systems. Increasingly, thesaurus applications need to mesh with others, such as automatic categorization schemes, free-text search systems, etc. Part 2 of ISO 25964 describes additional types of structured vocabulary and gives recommendations to enable interoperation of the vocabularies at all stages of the information storage and retrieval process.
T.2: The ability to identify and locate relevant information among vast collections and other resources is a major and pressing challenge today. Several different types of vocabulary are in use for this purpose. Some of the most widely used vocabularies were designed a hundred years ago and have been evolving steadily. A different generation of vocabularies is now emerging, designed to exploit the electronic media more effectively. A good understanding of the previous generation is still essential for effective access to collections indexed with them. An important object of ISO 25964 as a whole is to support data exchange and other forms of interoperability in circumstances in which more than one structured vocabulary is applied within one retrieval system or network. Sometimes one vocabulary has to be mapped to another, and it is important to understand both the potential and the limitations of such mappings. In other systems, a thesaurus is mapped to a classification scheme, or an ontology to a thesaurus. Comprehensive interoperability needs to cover the whole range of vocabulary types, whether young or old. Concepts in different vocabularies are related only in that they have the same or similar meaning. However, the meaning can be found in a number of different aspects within each particular type of structured vocabulary: - within terms or captions selected in different languages; - in the notation assigned indicating a place within a larger hierarchy; - in the definition, scope notes, history notes and other notes that explain the significance of that concept; and - in explicit relationships to other concepts or entities within the same vocabulary. In order to create mappings from one structured vocabulary to another it is first necessary to understand, within the context of each different type of structured vocabulary, the significance and relative importance of each of the different elements in defining the meaning of that particular concept. ISO 25964-1 describes the key characteristics of thesauri along with additional advice on best practice. ISO 25964-2 focuses on other types of vocabulary and does not attempt to cover all aspects of good practice. It concentrates on those aspects which need to be understood if one of the vocabularies is to work effectively alongside one or more of the others. Recognizing that a new standard cannot be applied to some existing vocabularies, this part of ISO 25964 provides informative description alongside the recommendations, the aim of which is to enable users and system developers to interpret and implement the existing vocabularies effectively. The remainder of ISO 25964-2 deals with the principles and practicalities of establishing mappings between vocabularies.

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.
