A Comparative Study of Machine Learning Models for Wordforms Morphological Analysis

Student: Lipinskiy Sergey

Supervisor: Elena I. Bolshakova

Faculty: Faculty of Computer Science

Educational Programme: Data Science (Master)

Year of Graduation: 2019

This work is dedicated to applying machine learning models in the task of a morpheme analysis of words in Russian. The morpheme analysis implies word’s segmentation into morphs and definition of morphological type of each morph. In this work existing models of morpheme segmentation analysis were reviewed. The series of experiments were made in order to improve the efficiency of the existing model of morpheme segmentation based on the convolutional neuron network. In particular the experiments were implemented in order to modify marking of letters in words of the dataset, as well as to modify the architecture of the neuron network. The multiple versions of the morpheme analysis model were obtained, which were afterwards compared based on the efficiency of their performance.
