Automatically Creating a Lexicon of Verbal Polarity Shifters: Mono- and Cross-lingual Methods for German

This repository contains the data created as part of:

Marc Schulder, Michael Wiegand, Josef Ruppenhofer (2017). "Automatically Creating a Lexicon of Verbal Polarity Shifters: Mono- and Cross-lingual Methods for German". Proceedings of the 27th International Conference on Computational Linguistics (COLING 2018). Santa Fe, New Mexico, USA, August 20 - August 26, 2018.

Content

We provide a bootstrapped lexicon of German verbal polarity shifters. Our lexicon covers 2595 verbs of GermaNet (Hamp and Feldweg, 1997). Polarity shifter labels are given for each word lemma. All labels were assigned by an expert annotator who is a native speaker of German.

  • LREC 2018: Lexicon of English Verbal Shifters (manual, sense-level)

Files

The data consists of two lists of GermaNet verbs (Hamp and Feldweg, 1997), annotated for whether they cause shifting:

  1. verbal_shifters.gold_standard.txt: The initial gold standard (§3) of 2000 randomly sampled verbs.
  2. 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.
