Weighting Towards Module Mark ( %)
|
-
Students will carry out multimedia information modelling tasks and submit work with a total of 1000 words of description and justification.
-
They will implement part of a multimedia application, using software such as Lucene search engine.
- Marks will be awarded for the appropriate modelling of the multimedia data given the intended users of the application, and for the technical implementation and understanding.
- Students will submit a 1000-word report and present their findings. The report should demonstrate their application and explain /justify their decisions.

| Module Overview |
This module will provide students with an understanding of modelling multimedia information (text, image, video and audio data) in a variety of multimedia information retrieval and browsing applications, including personal media collections, organisation-wide media archives, web-search engines, and virtual worlds. |
|
|
| Prerequisites/Co-requisites |
CS183 Systems Analysis and Design

|
|
| Module Aims |
The module aims to help students gain understanding of the current study of multimedia information retrieval and provide practical skills for modelling multimedia items appropriately for particular applications.
|
|
|
| Learning Outcomes |
By the end of the module students should be able to:
1. Apply appropriate techniques for analysing and modelling text documents
2. Explain theories behind search engine systems and assess their performance
3. Apply a standard metadata set to describe media items in an archive
4. Compare and apply different kinds of metadata for image data
5. Distinguish and apply appropriate data models for temporal media (video/audio)
6. Describe video content formally, in terms of objects, events and temporal relationships between events
7. Design and implement a synchronised multimedia presentation including a variety of media types and temporal relationships
8. Explain, contrast and evaluate the modelling of multimedia information to support media access, especially retrieval and browsing, in a variety of applications - these include personal media collections, organisation-wide media archives, web-based search engines, and virtual worlds.
Explain theories behind hypermedia systems and assess how this is put into practice in current hypermedia applications |

| Module Content |
· Modelling text data and keywords – inverted index, thesauri for query expansion, precision/recall
· Metadata for multimedia – e.g. the Dublin Core Metadata Set, MPEG-7·
· Key concepts: user information needs, modelling, media access functions – retrieval and browsing, multimedia content and different levels of abstraction·
· Current multimedia applications, including personal media collections, organisation-wide media archives, web-based search engines, and virtual worlds: considering exemplar applications such as Flickr, YouTube and Second Life.
· Modelling the content of images – content independent, content-dependent, content-descriptive metadata; case studies of image retrieval systems·
· Modelling the content of temporal media (video and audio) – data models with discrete, overlapping and hierarchical intervals; formal descriptions of objects, events and temporal relationships between events; the MPEG standards·
· Combining media items into synchronised presentations using the Synchronised Multimedia Integration Language (SMIL)Hypermedia – theory and practice; how does the web shape-up as a hypermedia system? |

|
| Methods of Teaching/Learning |
The module will develop an understanding for the role of modelling multimedia information through:
- Lectures, including case studies
- Occasional set reading
- In-class discussion
The module will develop practical skills through:
- In-class and out-of-class exercises
- Lab sessions
- Coursework
All activities will be co-ordinated via the module webpage and through ULearn. |

|
| Selected Texts/Journals |
There is no textbook recommended for purchase.
Sections of books will be given as Optional Reading and will be made available via the Library Article Collection service. Further Optional Reading will be given from online resources, e.g. technical standards and academic journals.
