Credits: 5
NFQ Level:Expert
Field of Study: Computer Science
Valid From: Semester 1 - 2018/19 ( September 2018 )
Module Delivered in 1 programme(s)
Module Coordinator: TIM HORGAN
Module Author: Ted Scully
Module Description: Natural language processing (NLP) is a set of statistical and machine learning techniques applied to the analysis and synthesis of natural language and speech. This module will provide learners with a comprehensive introduction to the theory underpinning NLP and will also equip learners with the knowledge to implement and apply NLP algorithms and techniques to real-world problems such as sentiment analysis.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Apply and evaluate a language modelling technique such as n-grams to a natural language processing problem.
LO2 Compare and contrast the use of parsing techniques for context-free grammar problems.
LO3 Develop and evaluate a document classification model using machine learning techniques.
LO4 Implement a machine translation model for real-world data and assesses it's performance.
Pre-requisite learning
Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named CIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
No recommendations listed
Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.
No incompatible modules listed

Module Content & Assessment

Indicative Content
Language Modelling
Introduction to natural language processing and language models. N-gram modelling, The Markov assumption and maximum likelihood estimation. Evaluating language models, perplexity, generalization, smoothing techniques and dealing with unknown words. Hidden Markov models and part-of-speech tagging.
Parsing for NLP
Context free grammar. Syntactic parsing. Structural, attachment and coordination ambiguity. Handling structural ambiguities using the CKY algorithm. Statistical parsing, probabilistic context free grammars for disambiguation. Learning PCFG rule probabilities. Dependency Parsing. Dependency grammars and typed dependency structure.
Machine Learning
Document classification using machine learning techniques such as naive bayes (mutli-nomial and bernoulli models), support vector machines, logistic regression and neural networks (embedding dense word vectors).
Machine Translation (MT)
Introduction to linguistic knowledge. Rule-based MT (transfer-based MT and inter-lingual MT. Statistical MT (word and phrase-based translation). Neural MT and vector-based representations. MT evaluation metrics (WER, BLEU and TER).
