- Abstract
- Formal Concept Analysis (FCA) is a well founded mathematical framework used for conceptual classication and knowledge management. Given a binary table describing a relation between objects and attributes, FCA consists in building a set of concepts organized by a subsumption relation within a concept lattice. Accordingly, FCA requires to transform complex data, e.g. numbers, intervals, graphs, into binary data leading to loss of information and poor interpretability of object classes. In this paper, we propose a pre-processing method producing binary data from complex data taking advantage of similarity between objects. As a result, the concept lattice is composed of classes being maximal sets of pairwise similar objects. This method is based on FCA and on a formalization of similarity as a tolerance relation (reexive and symmetric). It applies to complex object descriptions and especially here to interval data. Moreover, it can be applied to any kind of structured data for which a similarity can be dened (sequences, graphs, etc.). Finally, an application highlights that the resulting concept lattice plays an important role in information fusion problem, as illustrated with a real-world example in agronomy.

- Abstract
- Das Thema Literaturverwaltung hat in den letzten Jahren in der Softwareentwicklung, aber auch bei den wissenschaftlichen Bibliotheken einen enormen Aufschwung erfahren: kostenlose Softwarelizenzen sowie Schulungs- und Supportangebote gehören mittlerweile vielerorts zum Dienstleistungsspektrum der Bibliotheken. Die Verbreitung dieser bibliothekarischen Serviceangebote genauer zu benennen und zugleich in der Praxis bewährte Dienstleistungen zu identifizieren, war Ziel einer im Februar 2010 durchgeführten Online-Umfrage, deren Ergebnisse hier vorgestellt werden.

- Abstract
- Die hier aufgeführten Regeln beziehen sich ausschließlich auf hier aufgeführte Relationsarten und die Beziehungen unter ihnen. Die Ergebnisse sind in Zusammenarbeit mit der Thesaurusredaktion des Projekts ATLAS entstanden (ATLAS 1990). Gedanken von Rostek & Fischer (1988), Schäuble (1989), Vanek (1980), Sick (1989) und Konrad (1990) sowie die Empfehlungen der DIN 1463 (1987) wurden mit berücksichtigt. Diese Regeln werden außerdem für die Entwicklung des Textinterpretationssystem ATLAS/ti (Muhr 1990) und ATLAS/PfleSaurus (Willenborg 1991) weiterverwendet. Punkt 1. enthält Definitionen: Thesaurus, Thesaurusrelationen und deren formal logische Eigenschaften. Punkt 2. enthält Konsistenzregeln. Punkt 3. enthält Inferenzregeln. Punkt 4. enthält zwei Beispielthesauri. Ein System zur Erstellung und Pflege von Thesauri solllte die unter Punkt 1.-3. beschriebenen Definitionen und Regeln berücksichtigen.

- Abstract
- Die zunehmende weltweite Vernetzung und der aufbau von digitalen Bibliotheken führt zu neuen Möglichkeiten bei der Suche in mehreren Datenbeständen. Dabei entsteht das Problem der semantischen Heterogenität, da z.B. Begriffe in verschiedenen Kontexten verschiedene Bedeutung haben können. Die dafür notwendigen Transferkomponenten bilden eine neue Herausforderung, für die neuronale Netze gut geeignet sind
