GermaNet is a lexical-semantic net that relates German nouns, verbs, and adjectives semantically by grouping lexical units that express the same concept into synsets and by defining semantic relations between these synsets. GermaNet has much in common with the English WordNet (http://wordnet.princeton.edu) and can be viewed as an on-line thesaurus or a light-weight ontology.
GermaNet has been developed and maintained within various projects by the research group for General and Computational Linguistics (Director: Prof. Dr. Erhard Hinrichs) at the University of Tübingen since 1997.
The most important extensions to this GermaNet release compared to the previous release are:
1: New synsets and lexical units for all word categories, and new relations have been added.
2: All nominal compounds have been split into their constituents (modifier and head) that are labelled with linguistic information such as foreign words and named entities. For more details, please see http://www.sfs.uni-tuebingen.de/GermaNet/compounds.shtml
3: The German part of the Interlingual Index (ILI), which was initially created in the context of the EuroWordNet project, has been extended. It represents a mapping between wordnets of different languages. For detailed information see http://www.sfs.uni-tuebingen.de/GermaNet/ili.shtml
