This dataset contains the Russian-language data I collected for training reverse dictionaries. The data consists of Russian words and their definitions. Each word-definition pair is also labeled with its source, of which there are three:

- 'efremova' (circa 210K) refers to the Efremova's New Explanatory-Morphological Dictionary (2000), which is an authoritative Russian dictionary that was chosen for its lack of examples (allowing for easier data collection) and the large amount of words represented (circa 140K);
- 'codwoe' (circa 50K) refers to the dataset created by the organizers of the CODWOE (COmparing Definitions and WOrd Embeddings) track of SemEval-2022, available here: https://codwoe.atilf.fr/. This part of the dataset only contains definitions for nouns, verbs, adjectives and adverbs. Notably, the original dataset also contains (usually several) examples of use for every word; I have not retained them here, but if you need examples of use in your training (for instance to generate embeddings) they are freely available there;
- 'absite' (circa 35K) refers to absite.com, a Russian-language crossword website, from where I scraped words and clues for them. Unlike the other parts of the dataset, 'absite' contains only definitions for nouns; but since the definitions here are crossword clues and not dictionary definitions, they are written in a more everyday style of Russian, which corresponds to how a hypothetical user of a reverse dictionary would likely phrase their queries.

There are circa 294K datapoints in total. 

Note: this dataset is filtered from the dictionary definitions of words that are represented in the testing data that I used. If you want the full dataset (for instance, if you're generating testing data in some other way, including from this dataset), it is available here: https://huggingface.co/datasets/snagbreac/russian-reverse-dictionary-full-data . The testing data is available here: https://huggingface.co/datasets/snagbreac/russian-reverse-dictionary-test-data .

I sincerely hope that someone finds this dataset useful for training reverse dictionaries, both Russian-language and multilingual.
