Overview

Intelligent systems need to be able to represent and reason about the world. This course provides an introduction to the key ideas in knowledge representation and different types of automated reasoning. The course is a mixture of theoretical and practical work: at the end of the course students will know the principles that such systems use, and they will have experience of implementing those principles in running systems.

Pre/co-requisites

Students who are not from the School of Computer Science must have permission from both Computer Science and their home School to enrol.

Aims

The aim of this course is to provide the conceptual and practical (systems building) foundations for knowledge representation and reasoning in Artificial Intelligence.

Learning outcomes

  • Describe the syntax and semantics of first-order logic and use it to model problems

  • Apply reasoning techniques (transformation to clausal form, resolution, saturation) to establish properties of first-order problems 

  • Explain the theoretical limitations of automated theorem provers

  • Write Prolog programs to solve automated reasoning tasks and explain how they will execute

  • Describe, differentiate and apply different knowledge representation formalisms for modelling knowledge bases.

  • Explain how these formalisms affect the reasoning process.

  • Apply, demonstrate and program knowledge-based learning methods.

  • Apply, demonstrate and program formal models for natural language processing in the context of semantic parsing and natural logic inference.
