Polar Quantification of Actor Noun Phrases for German

Proceedings of the Thirteenth International Conference on Language Resources and Evaluation (LREC 2022)

Abstract

In this paper, we discuss work that strives to measure the degree of negativity - the negative polar load - of noun phrases, especially those denoting actors. Since no gold standard data is available for German for this quantification task, we generated a silver standard and used it to fine-tune a BERT-based intensity regressor. We evaluated the quality of the silver standard empirically and found that our lexicon-based quantification metric showed a strong correlation with human annotators.
