Semester: SEM1
Originating Department: Electrical and Electronic Engineering
Pre-requisites: N/A
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

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.
1. Basic information retrieval operations.

Covering indexing, retrieval, filtering, clustering, summarization, abstraction.

2. Information retrieval on text

Retrieval using metadata including SGML, XML, XSL, HTML, stemming and stop words, inverted files, term weighting, term weighting models, relevance feedback, query expansion. Ranking retrieval:

Vector space model, variant weighting schemes, scoring. Probabilistic information retrieval and text classification: Naïve Bayes text classification, Rocchio classification

3. Evaluation of information retrieval system

Precision and recall, average precision, mean average precision, normalized discounted cumulative gain

4. Information theory

An introduction to the basics of information theory including information content, information entropy and the Shannon value.

5. Lossless coding
