Aims
The aim of this module is to present the student with an overview and an understanding of how
content-based information retrieval operations work.

The module covers content-based operations such as indexing, retrieval, filtering,
summarisation,and information extraction and is applied to text, image, spoken audio and digital
video information.

The module includes coverage of these topics as they are applied to the WWW.

Students learn modern methods for the capture, encoding, storage, transmission and presentation
of digital multimedia information including both the underlying information theory and mediaspecific
techniques for perceptual coding.
Learning outcomes 
1. Demonstrate a clear understanding of the principles underlying information retrieval systems.

2. Apply information retrieval techniques to a range of applied problems.

3. Interpret an information retrieval system requirement, and design a suitable solution system.

4. Describe and justify a plan for implementation and testing of designed solution

5. Produce an information-theoretical analysis of coding problems

6. Calculate the information content of a message or file to be transmitted or stored

7. Select coding algorithms appropriate to a variety of lossless coding problems

8. Select coding algorithms appropriate to a variety of perceptual coding problems

9. Sketch in outline algorithms for lossy (perceptual) coding

10. Identify features of multimedia data for which information loss is less likely to be
perceptable

11. Estimate the cost of executing various lessless and perceptual coding schemes

12. Explain the architectural considerations behind various modern perceptual coding schemes
Method of teaching and learning 
This module will be delivered through a combination of formal lectures and tutorials.
