NATURAL LANGUAGE PROCESSING - 2024/5

Module Overview

This module will demonstrate fundamental concepts from the field of Natural Language Processing (NLP) and Computational Linguistics. It will also discuss some of the latest advances in NLP and Generative Artificial Intelligence with a focus on Language Models like BERT, T5, and GPT, and get student up to speed with current research. It will provide the necessary skills to enable students to build computational models for solving a range of problems, such as text classification, sequence classification, machine translation and building conversation agents. The students will learn how to build NLP pipelines for preparing training data and choosing appropriate algorithms and techniques to build such models. The module also focuses on aspects of ethical and trustworthy artificial intelligence with discussion on rigorous model evaluation and ethical considerations for computational modeling. Although traditional linguistic approaches will be mentioned, majority emphasis will be put on the state-of-the-art Deep Learning algorithms and Transfer Learning methods for building efficient and trustworthy NLP solutions.

Assessment pattern

Alternative Assessment

Individual coursework covering the same learning objectives

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate:

• ability to demonstrate learning of theoretical fundamental for language processing.

• ability to critically evaluate, and apply appropriate techniques to build computational models, exemplifying specific dataset characteristics in order to derive suitable and defensible results.

• ability understand the needs and build appropriate problem solving skills for a range of NLP problems

Thus, the summative assessment for this module consists of:

• GROUP PROJECT: A group coursework in which the students will bring together their experiments from the first coursework and will build a proof of concept that will need to demonstrate both technical understanding and good practice. The coursework will be marked based on the approach and breadth of experimentation, rather than on the performance of the computational models. This addresses LOs 3, 4, 5, and 6. 


• INVIGILATED EXAMINATION: An exam testing the understanding of theoretical concepts taught in the module. Analytical and critical thinking shall be assessed via this component. This addresses LOs 1, 2, 4, and 6. 

Formative assessment and feedback

Students will be guided to work on weekly tasks through lab exercises, the solutions to which will provide for feedback on understanding and practice.

Verbal feedback on student efforts alongside help in executing the lab tasks are provided to the student. 

Labs and feedback will then support the coursework. 

Module aims

• Provide an overview of the fundamentals and concepts that support the development of NLP models.
• Familiarise students with NLP applications and what approaches can be adopted to experiment and build such applications.
• Demonstrate how NLP processing pipelines can be formed to perform necessary transformations towards building computational models.
• Bring students up to a sufficient level of development skill to be able to develop NLP models that solve specific tasks.

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

• Develop a critical understanding of best practice in developing state-of-the-art NLP solutions through directed learning and facilitated self-directed learning. The skills learned in this module will be transferable to other data science and AI modules in the programme and the wider data science profession.

The learning and teaching methods include:

• Lectures with class discussion

• Lab sessions with formative feedback

• An additional learning component which focuses on a specific aspect of NLP and/or AI 

• Use of an online forum for facilitated discussion

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
