Computational linguistic tools for semi-automatic corpus-based updating of dictionaries

We will demonstrate an interface which allows the lexicographer to view the results of an automatic 
comparison of lexicographic descriptions from existing German dictionaries with corpus data. The second 
part of the paper will discuss in detail the use made of the raw material in the recent update of 
Langenscheidt's Grosworterbuch Deutsch-Englisch, Der kleine Muret-Sanders. The examples in the 
online-demonstration come from work on entries for headwords with the initial letter "T" in Duden. Das 
grose Worterbuch der deutschen Sprache (8 vols.; Duden GWDS) and from the German part of Langenscheidts 
Handworterbuch Deutsch-Englisch (HWB). Both have been compared with data extracted from 
large newspaper corpora. The interface makes use of a standard web browser for display of lexical data. 
The demonstration will be a guided tour of the data collection, from the lexicographic point of view. The 
first part of this paper provides the metalexicographic baseline, a short summary of the technology used 
to develop the data collection, a few examples of the types of data made available. The second part deals 
with the practical lexicographic use of the data collection in the update of Der kleine Muret-Sanders.
