Ukrainian Hypernymy Pairs Dataset

Background

Hypernymy is the super-subordinate or ISA semantic relation that links more general terms to more specific ones. For example, rose is a hyponym of flower, a hypernym of rose. Words that are hyponyms of the same hypernym are called co-hyponyms, for instance, rose and tulip. Hyponymy relation is transitive and asymmetric.

Hypernymy is also differentiated by:

• Types — common nouns: armchair is a type (hyponym) of chair;
• Instances — specific persons, countries, and geographic entities: Dnipro river is an instance (instance hyponym) of river.

Project Description

The Ukrainian Hypernymy Pairs Dataset is a collection of noun pairs that express hypernymy relations between words in the Ukrainian language. The dataset contains pairs of words linked by four different types of relations: hypernym-hyponym, co-hyponyms, hypernym-instance, and co-instances.

An example of such a dataset in English may be BLESS. However, their concepts are linked by one of the following six relations: co-hyponyms, hypernyms, meronyms, attributes, events, and random. Moreover, the hypernymy relation is not divided by terms and instances.

Ukrainian Hypernymy Pairs were constructed utilizing the linkage between Princeton WordNet, Wikidata, and Ukrainian Wikipedia. We used the Python Wn package to get the relation, which provides an interface to WordNet data.

All terms in the dataset are Wikipedia article titles, and no preprocessing was applied. Therefore it sometimes contains additional info in the brackets.

Dataset Statistics

This table presents the number of word pairs obtained for each relation type.

Relation Type	# of Pairs
Hypernym-Hyponym	6,906
Co-Hyponyms	42,860
Hypernym-Instance	2,971
Co-Instances	22,927
Total # of Pairs	275,664

Intended Use

The dataset produced can be particularly valuable for the Hypernym Detection task, where the pair of words is presented to a model, and it should classify whether they are in a hypernymy relation. Other lexico-semantic relations can be added to improve the diversity of the dataset.
