We are happy to announce the availability of three new resources for the
German wordnet GermaNet:

1) WebCAGe (short for: Web-Harvested Corpus Annotated with GermaNet Senses) is
a domain-independent web-harvested corpus that has been semi-automatically
annotated with senses from GermaNet. The corpus has been constructed on the
basis of a the sense alignment of GermaNet senses with senses from the online
dictionary Wiktionary. Wiktionary senses are frequently illustrated by one or
more example sentences, which in turn are often linked to external references,
including Wikipedia articles and other textual web sources. Therefore, the
GermaNet-Wiktionary alignment and the various pointers contained in Wiktionary
example sentences made it possible to automatically assemble a corpus
annotated with GermaNet senses. In order to assure good quality, all automatic
annotations have been manually verified. WebCAGe is freely available for
download at:
http://www.sfs.uni-tuebingen.de/en/ascl/resources/corpora/webcage.html

2) Semantic Relatedness API: To calculate semantic relatedness between two
word senses in GermaNet, we have reimplemented a suite of semantic relatedness
algorithms for German that are well-known for English, including the methods
proposed by Leacock and Chodorow (1998), Wu and Palmer (1994), Hirst and
St-Onge (1998), Resnik (1995), Jiang and Conrath (1997), Lin (1998), and Lesk
(1986):

3) GernEdiT (GermaNet Editing Tool) is a graphical editor that supports
several ways to search and visualize GermaNet data. It can be used to browse
through the GermaNet graph, to list all senses of a word, and to view all
properties of a particular word sense, including relations to other word
senses, Wiktionary paraphrases, and English translations. GernEdiT is used by
the lexicographers to maintain and extend the GermaNet database in a
user-friendly way. Now we made GernEdiT available for interested users:

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.
