Assignment

Data source

Download the New Zealand's knowledge network data from the class moodle. It represents a sample of New Zealand's publication network that I constructed based on 3,385 computer science related publications (from 1972-2016); where nodes represent authors and links represents co-authorship relations. This is a network file (.net) and opened/read by either NodeXL or Gephi (or any other tool of your choice listed below) to construct and analyze the network.

Your Task

Your goal is to analyse construct the network and then write a short report about this network. Describe interesting features, important institutions, relationships, etc. This is not something you can do just by looking at the structure - you will need to analyze network property (both node level and network level properties). You should provide a deep investigation into this network. Who are the central institutions/universities? What is their role in the network (e.g., their Degree, Betweenness, and Eigenvector Centrality)? What are the big clusters? What does each represent? How did you find that out? I want a thorough analysis of all the major features of the network. Figure 1 below is an example of the network that I constructed from the same data using NodeXL. Where nodes represent institutions and links represent collaboration ties. In this instance, Node size represents betweenness centrality and link width represents intensity of collaboration.

Your Final Report & Grading

It is important that in your final report to be analytical rather than descriptive and should include following analysis:

1. The report includes a meaningful visualization of the network. Try to replicate figure 1 with different colours (I will not accept similar colours). You should filter the network, for example, highlighting the important nodes, showing intensity of collaboration (e.g., with links width and colours) (5 marks).

2. The report includes network level statistics (such as, total number nodes, clustering co- efficient, average degree, density, and diameter) with brief explanation of results. What does it say about the network? (5 marks).

3. The report includes a list of top 10 nodes (institutions) in terms of degree, betweennes, and eigenvector centralise accompanied by with brief explanation the results. Instead, give a meaningful description of who the institutions are, what their role is in the network, and how their research activities relate to that role, etc. (5 marks).

4. In terms of Eigenvector Centrality, what is the position of Waikato University as compared to others and what does it mean? (5 marks).

Formatting Guidelines

1. Final report should be no more than 1000 words (excluding tables and references), 12-point font, and one-inch margins.
2. Include page numbers to facilitate review.
3. The first page should provide the student name and ID.
4. Use headings and subheadings to facility the review.
