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
