One of the most urgent problems in language technology is the lexical semantics bottleneck, the unavailability of domain-independent lexica with rich semantic information on lexical items. Such lexica could greatly improve the quality of current applications. At the same time, providing large-scale lexical semantic information is an enormous challenge, due to the size of the vocabulary and the inherent vagueness of lexical meaning. Our aims are:
  • Providing a large lexical semantic lexicon providing semantic and syntactic properties for German lexical items, to serve as a rich static database.
  • Developing techniques for the wide-coverage statistics-based semantic annotation of texts.
  • Investigating the use of contiguous frame annotations for dynamic semantic analysis in practical natural language processing applications
These aims are reflected in the three main blocks of the graphical overview of the project:
