SALSA The Saarbrücken Lexical Semantics Annotation & Acquisition Project Aljoscha Burchardt, Katrin Erk, Anette Frank, Andrea Kowalski, Sebastian Pado, Manfred Pinkal

Semantic Annotation in SALSA Manual semantic annotation of 0.8 million words of syntactically annotated German newspaper text (TIGER Corpus, Releases 1, 2) with frames and frame elements (Berkeley FrameNet Database), staying as close as possible to the Berkeley FrameNet database

SALSA: What's special? SALSA is about German Cross-lingual divergencies?

Cross-lingual Divergencies Convincing cross-lingual portability results (E  D) in general Adaptation necessary because of Inappropriate granularity of distinctions between FEs Missing FEs (Rare cases of) inappropriate granularity of frames

SALSA: What's special? SALSA is about German Cross-lingual divergencies? Corpus-driven lexicon development through exhaustive full-text annotation Difficult cases Incompleteness of Berkeley FrameNet

Difficult cases Metaphors Support Verb Constructions Idioms
