YearMSc
PrerequisitesNormally offered only to students in computer science related programmes because programming skills are required for the coursework project.
Term1

AimsThis module introduces the fundamental concepts, principles and methods in the interdisciplinary academic field of network science, with a particular focus on the Internet, the World Wide Web and online social media networks. Topics covered include graphic structures of networks, mathematical models of networks, the Internet topology, structure of the Web, community structures, epidemic spreading, PageRank, temporal networks and spatial networks.
Learning Outcomes

On successful completion of this module the students will be able to:

  • Define and calculate basic network graphic metrics.
  • Describe structural features of the Internet and the Web.
  • Relate graphic properties to network functions and evolution.
  • Explore new angles to understand network collective behaviours.
  • Design and conduct analysis on large network datasets.

 

Content

Network science
Complex networks
Network graphic metrics
Random networks
Small-world networks
Scale-free networks
Network mathematical models
Network structural constraints

Online social media networks - Twitter, Facebook, Amazon, …

Network functions and behaviours
“Rich gets richer” phenomenon
Link, neighbourhood and community
Cascades and epidemics 
Network structure balance
Sentimental, temporal and spatial analysis of social media networks

Method of Delivery

A Moodle webpage is created for the course. All course materials, such as lecture notes and online resources will be shared. By using the Moodle, students will also be able to discuss ideas and questions with the lecturer and other students.

 

In the second half of the term, there will be a weekly one-hour lab/tutorial session, where the lecturer and/or a teaching assistant will discuss questions with students.

 

 

Assessment

The module has the following assessment components:

  • Unseen written examination (2.5 hour, 70%)
  • Course project (30%)

To pass this module, students must:

  • Obtain an overall pass mark of 50% for all components combined.

(The Course Project consists of an individual project on network data analysis (programming is usually required), and a project report (3000 words), including literature survey, which is due by the end of the Winter Holidays.)
