    Abstract
    Das aktuelle Wissen der Welt im Spiegel einer Weltausstellung: Wie stellt man das dar und wie macht man es Interessierten zugänglich - in der Ausstellung, in Publikationen, im Funk und über das Internet? Was man alles auf einer Weltausstellung an der Schwelle zum dritten Jahrtausend sehen und erfahren kann, sprengt in Fülle und Vielfalt jeden individuell faßbaren Rahmen. Schmitz-Esser zeigt in seinem Buch, wie der Besucher wahlweise in vier Sprachen die Weltausstellung erleben und die Quintessenz davon mitnehmen kann. Ermöglicht wird dies durch das Konzept des virtuellen "Wissens in der Kapsel", das so aufbereitet ist, daß es in allen gängigen medialen Formen und für unterschiedlichste Wege der Aneignung eingesetzt werden kann. Die Lösung ist nicht nur eine Sache der Informatik und Informationstechnologie, sondern vielmehr auch eine Herausforderung an Informationswissenschaft und Computerlinguistik. Das Buch stellt Ziel, Ansatz, Komponenten und Voraussetzungen dafür dar.

    Abstract
    Thesaural relations have long been used in information retrieval to enrich queries; they have sometimes been used to cluster documents as well. Sometimes the first query to an information retrieval system yields no results at all, or, what can be even more disconcerting, many thousands of hits. One solution is to rephrase the query, improving the choice of query terms by using related terms of different types. A collection of related terms is often called a thesaurus. This chapter describes the lexical-semantic relations that have been used in building thesauri and summarizes some of the effects of using these relational thesauri in information retrieval experiments

    Abstract
    A set of semantic relations is created every time a domain modeler wants to solve some complex problem computationally. These relations are usually organized into ontologies. But three is little standardization of ontologies today, and almost no discussion an ways of comparing relations, of determining a general approach to creating relations, or of modeling in general. This chapter outlines an approach to establishing a general methodology for comparing and justifying sets of relations (and ontologies in general). It first provides several dozen characteristics of ontologies, organized into three taxonomies of increasingly detailed features, by which many essential characteristics of ontologies can be described. These features enable one to compare ontologies at a general level, without studying every concept they contain. But sometimes it is necessary to make detailed comparisons of content. The chapter then illustrates one method for determining salient points for comparison, using algorithms that semi-automatically identify similarities and differences between ontologies.

    Abstract
    Relationships can provide a rich and powerful set of information and can be used to accomplish application goals, such as information retrieval and natural language processing. A growing trend in the information science community is the use of information visualization-taking advantage of people's natural visual capabilities to perceive and understand complex information. This chapter explores how visualization and visual exploration can help users gain insight from known relationships and discover evidence of new relationships not previously anticipated.
