Social and Technological Network Analysis
1 - Research paper report
Every student will prepare one report (of approximately 1,500 words) on one assigned research paper. The report is worth 30% of the final mark.
The report will contain two parts of about 750 words each:
- Critical analysis of the papers including, possibly, comparisons and references to other material presented in the course or found by the student and comments on how solid the result obtained are (e.g., comments on the evaluation methods or on the analysis applied can be included).
- Discussion of possible future research ideas in the area.
This is a selection of mainly recent research papers on social and technological networks. Choose any still available paper and e-mail your choice to cm542: the submission of reports is to be done via email to cm542 in PDF format in addition to handing a hard copy to the office.

2 - Project
Every student will complete a project which consists of analysis of an assigned dataset according to some indicated network measures using NetworkX: the analysis should be reported in a document of about 1,500 words where the results are commented and justified. This will be worth 50% of the final mark.
Each student is encouraged to come up with original project proposals which may be inspired by the ideas reported below.
Deadline for choice: 14th February 2014
Deadline for submission: 11th March 2014 at noon

3 - Presentation
Every student will prepare a brief oral presentation of the project findings. Each presentation MUST last 8 minutes, including questions: thus, a reasonable combination would be a 6-minute talk followed by 2 minutes for questions.
The presentations will take place on 12th March 2014.

The presentation is worth 20% of the final mark and it will be evaluated along these categories:
- Presentation skills [20%]
- General knowledge of the subject [20%]
- Discussion of findings [40%]
- Questions and answers [20%]
