Natural Language Understanding

Unit code COMP34812
Credit rating 10
Unit level Level 3
Teaching period(s) Semester 2
Offered by Department of Computer Science
Available as a free choice unit? No

Overview

Drawing from concepts covered in the prerequisite COMP34711: Natural Language Processing unit, this unit will enable students to look more deeply into how machines analyse and recognise meaning expressed in natural language. In this unit, students will gain hands-on experience in investigating solutions to a number of natural language understanding tasks. This will provide students with the know-how required to develop technologies for real-world applications enabling communication between humans and machines, which have become increasingly ubiquitous and indispensable.

Pre/co-requisites

Unit title Unit code Requirement type Description
Natural Language Processing COMP34711 Pre-Requisite Compulsory

Aims

The unit aims to:

- introduce students to the concepts and computational methods that enable machines to understand and interpret natural language

-  explain the various tasks that underpin natural language understanding, and provide an overview of the state-of-the-art solutions to these tasks as well as their real-world applications

Learning outcomes

  • To discuss the formulation of different natural language understanding tasks as sequence processing tasks e.g., sequence classification, sequence-to-sequence translation and sequence labelling.
  • To differentiate between different types of parsing algorithms and apply them to natural language data to produce meaning representations.
  • To compare different approaches to tasks such as named entity recognition and sentiment analysis.
  • To relate natural language understanding tasks to applications such as question answering and conversational agents, among others.
  • To develop a solution to a natural language understanding task with application to a real-world problem

Syllabus

  • Introduction to NLU; Task formulations and applications
  • Meaning representations: symbolic parsing and logical representations of sentences
