+# 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](https://sites.google.com/site/geometricalmodels/shared-evaluation). 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](https://wordnet.princeton.edu/), [Wikidata](https://www.wikidata.org/wiki/Wikidata:Main_Page), and Ukrainian [Wikipedia](https://www.wikipedia.org/). We used the Python [Wn package](https://wn.readthedocs.io/en/latest/) 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 with the corresponding example.
+
+| **Relation Type**     | **Example Pair**          | **# of Pairs** |
+|-----------------------|---------------------------|----------------|
+| **Hypernym-Hyponym**  | Водойма, Море             | 6,906          |
+| **Co-Hyponyms**       | Море, Озеро               | 42,860         |
+| **Hypernym-Instance** | Море, Чорне море          | 2,971          |
+| **Co-Instances**      | Чорне море, Азовське море | 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.
