Compound or term features? : analyzing salience in predicting the difficulty of german noun compounds across domains
Proceedings of *SEM 2021: The Tenth Joint Conference on Lexical and Computational Semantics, *SEM 2021, Online, August 5-6, 2021, Association for Computational Linguistics, (2021)Abstract
Predicting the difficulty of domain-specific vocabulary is an important task towards a better understanding of a domain, and to enhance the communication between lay people and experts. We investigate German closed noun compounds and focus on the interaction of compound-based lexical features (such as frequency and productivity) and terminology-based features (contrasting domain-specific and general language) across word representations and classifiers. Our prediction experi ments complement insights from classification using (a) manually designed features to characterise termhood and compound formation and (b) compound and constituent word embeddings. We find that for a broad binary distinction into easy vs. difficult general-language compound frequency is sufficient, but for a more fine-grained four-class distinction it is crucial to include contrastive termhood features and compound and constituent features.
