Word Usage Graphs enriched with cluster definitions

This is a dataset of word usage graphs (WUGs), where the existing WUGs for multiple languages are enriched with cluster labels functioning as sense definitions. They are generated from scratch by fine-tuned encoder-decoder language models. The resulting enriched datasets can be helpful for explainable semantic change modeling.

Contents

• definitions_for_all_usages: mapping from usage identifiers to generated definitions
• code/: various scripts we used in preparing the datasets
• human_evaluation/: everything related to our evaluation efforts
• wug_labels/: the cluster labels themselves, the main part.

We provide cluster labels (sense definitions) for the following WUGs:

• Diachronic WUGs for English - English definitions
• Diachronic WUGs for German - German and English definitions
• NorDiaChange: Diachronic semantic change dataset for Norwegian (two subsets) - Norwegian and English definitions
• RuDSI: Word sense induction dataset for Russian - Russian and English definitions

Format

Every WUG dataset in the wug_labels/ directory contains target word subdirectories, according to the original DWUG format. Within each target word directory, we provide one file named cluster_gloss.tsv. It is a tab-separated dataframe with two columns:

• cluster: the numerical identifier of the cluster from the original WUG
• gloss: the definition generated for this cluster

The cluster labels should be used together with the original word usage graphs for the corresponding languages. As a rule, one can find clusters assigned to every specific WUG usage (sentence) in the clusters/ directory.

NB: some clusters are too small to generate a meaningful definition (less than 3 usages). In these cases, the definition is accordingly "Too few examples to generate a proper definition!".
