Bootstrapped Lexicon of German Verbal Polarity Shifters

We provide a bootstrapped lexicon of German verbal polarity shifters. Our lexicon covers 2595 verbs of GermaNet. Polarity shifter labels are given for each word lemma. All labels were assigned by an expert annotator who is a native speaker of German.

Data

The data consists of two lists of GermaNet verbs annotated for whether they cause shifting:

verbal_shifters.gold_standard.txt: The initial gold standard (§3) of 2000 randomly sampled verbs.

verbal_shifters.bootstrapping.txt: The bootstrapped 595 verbs (§5.3) that were labelled as shifters by our best classifier and then manually annotated.

Format

Each line contains a verb and its label, separate by a whitespace.
