- Abstract
- In diesem zweiten Teil wird ein formales Modell zur semantischen Interoperabilität als Brücke zwischen formaler Modellierung und intellektueller Interpretation vorgestellt, das ein besseres Verständnis der zentralen Begriffe von semantischer Ähnlichkeit und Verschiedenheit von Begriffen und Klassen, sowohl als elementare Inhaltsentitäten von Dokumentationssprachen als auch als synthetische Repräsentationen von Dokumentinhalten, ermöglichen soll.

- Abstract
- In diesem Beitrag wird ausgehend von einem ungelösten Problem der Informationserschließung ein Modell vorgestellt, das die Methoden und Erfahrungen zur inhaltlichen Dokumenterschließung mittels kognitiv zu interpretierender Dokumentationssprachen mit den Möglichkeiten formaler Wissensrepräsentation verbindet. Die Kernkomponente des Modells besteht aus der Nutzung von Inferenzen entlang der Pfade typisierter Relationen zwischen den in Facetten geordneten Entitäten innerhalb einer Wissensrepräsentation zur Bestimmung von Treffermengen im Rahmen von Retrievalprozessen. Es werden die möglichen Konsequenzen für das Indexieren und Retrieval diskutiert.

- Abstract
- Dieser aus zwei Teilen bestehende Beitrag setzt Methoden der semantischen Wissensrepräsentation in Verbindung zur Gestaltung von Retrievalszenarios für begriffliche Recherchen und insbesondere für die Wissensexploration. Ausgehend von heterogenen Erschließungssituationen werden Konzepte vorgestellt, wie durch Maßnahmen zur Herstellung von Interoperabilität ein Beitrag zur Lösung der Heterogenitätssituation geleistet werden soll. Basierend auf einem, im zweiten Teil vorgestellten, formalen Modell zum besseren Verständnis von semantischer Interoperabilität, wird ein Vorschlag für ein Gesamtsystem entwickelt, das aus einer Kernontologie und lokalisierten semantischen Netzen mit erweitertem Relationenumfang besteht. Die Möglichkeiten zur Recherche und Exploration in einem solchen Gesamtrahmen werden skizziert.

- Abstract
- Faceted arrangement of entities and typed relations for representing different associations between the entities are established tools in knowledge representation. In this paper, a proposal is being discussed combining both tools to draw inferences along relational paths. This approach may yield new benefit for information retrieval processes, especially when modeled for heterogeneous environments in the Semantic Web. Faceted arrangement can be used as a selection tool for the semantic knowledge modeled within the knowledge representation. Typed relations between the entities of different facets can be used as restrictions for selecting them across the facets.

- Abstract
- Starting from an unsolved problem of information retrieval this paper presents an ontology-based model for indexing and retrieval. The model combines the methods and experiences of cognitive-to-interpret indexing languages with the strengths and possibilities of formal knowledge representation. The core component of the model uses inferences along the paths of typed relations between the entities of a knowledge representation for enabling the determination of hit quantities in the context of retrieval processes. The entities are arranged in aspect-oriented facets to ensure a consistent hierarchical structure. The possible consequences for indexing and retrieval are discussed.
