Wiktionary Definitions

Since comprehensive sense definitions enhance the usability of GermaNet for a wide variety of NLP applications, we added sense definitions to GermaNet from the web-based dictionary Wiktionary. Therefore, we developed an algorithm that automatically harvests Wiktionary’s sense descriptions and maps them to corresponding lexical units in GermaNet. This automatic harvesting has been verified manually in order to assure high quality. For details about the mapping algorithm, please refer to our paper.


The definitions from Wiktionary have been mapped to lexical units in GermaNet. This mapping is freely available for download here:
