Course descriptionThis course is about processing natural and artificial languages, building on material covered in Informatics 1 concerning finite state machines and regular expressions. This course will consider how the same models of language can be used to describe and analyse both formal languages (such as programming languages) and natural languages (text and speech). It will include material on formal languages and grammars, probabilistic grammars (including hidden Markov models), semantic analysis and human language processing. Examples will be drawn from computer languages and natural language.

Summary of Intended Learning Outcomes
1 - Demonstrate knowledge of the relationships between languages, grammars and automata, including the Chomsky hierarchy;
2 - Demonstrate understanding of regular languages and finite automata;
3 - Demonstrate understanding of context-free languages and pushdown automata, and how how context-free grammars may be used to model natural language;
4 - Demonstrate knowledge of top-down and bottom-up parsing algorithms for context-free languages;
5 - Demonstrate understanding of probabilistic finite state machines and hidden Markov models, including parameter estimation and decoding;
6 - Demonstrate awareness of probabilistic context-free grammars, and associated parsing algorithms;
7 - Demonstrate knowledge of issues relating to human language processing.
