Course Contents

This course will discuss current computational models of human language processing. We will consider both how computational linguistics can inform the development of psycholinguistic theories, and also how computational models can account for and explain (experimentally) observed human language processing behaviour. The course will begin with an introduction to psycholinguistic research, summarising both the key observations about human language understanding, and also presenting central theoretical debates including issues such as modularity, incrementality, and the psychological status of linguistic principles and representations. We will then consider a number of computational models of lexical and sentence level processing and language acquisition. The models covered exploit symbolic, probabilistic, connectionist, and also 'hybrid' computational mechanisms.

Files for the tutorials will appear here, as the course goes on

The course will use several systems for experimenting with computational models of human language processing.
  • Prolog implementations of incremental parsers. You can get SWI-Prolog [here], and find online tutorials [here]
  • Probabilistic models of lexical and syntactic processing
  • Tlearn: for simple connectionist models

Systems are freely available, for Mac OS, Linux, and Windows operating systems.
