Course objectives

Machine translation is one of the practical applications of natural language processing. On its history, we can well illustrate approaches to text processing and artificial intelligence in general, from rule-based systems to machine learning using neural networks.
The aim of the course is to present:

the principles of machine translation, the techniques used for its solution;

an overview of the main translation directions in the past;

the ambiguity problem;

relations to the representation of knowledge and the representation of meaning;

data preparation for machine translation learning;

translation quality evaluation.
For modern deep learning techniques, parts of the code in Python as well as usage examples of existing systems will be presented.
The course also includes experiments with a simple neural-network-based translation system for Czech and English.

Learning outcomes

After completing the course, the student will be able to:

classify machine translation systems and state their foundations;

describe the components of a neural machine translation system;

understand the learning process of neural networks;

understand data generation methods for learning of MT systems;

create a simple machine translation system;

evaluate the quality of the translation.
