[Corpora-List] New resources and tools for GermaNet

[Verena Henrich]

Apologies for cross postings
------------------------

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.
