# Summary

Universal Derivations version of DeriNet.RU.


# Introduction

DeriNet.RU is DeriNet-like lexical network of that captures core word-formation relations for Russian. It is based on a top of large corpus Araneum Russicum Maius corpus and a novel combination of a grammar-based component, supervised machine-learning model of Random Forest, and Maximum Spanning Tree algorithm. (Kyjánek et et al., 2021).

The data structure of DeriNet.RU is rooted trees by default.


# Acknowledgments

We wish to thank all of the developers and annotators of the DeriNet.RU, including Lukáš Kyjánek, Olga Lyashevskaya, Anna Nedoluzhko, Daniil Vodolazsky, Magda Ševčíková, and Zdeněk Žabokrtský.
