About social network analysis tools and packages. There exist different tools and packages for social network analysis. In this course, we cover two of them in this course, with complementary advantages:
Learning goals. The main goal of this lab session is to become familiar with Gephi (experimental beta-software to visualize networks for research purposes) and its input format. At the end of this session you should be able to:
There is no deliverable for this lab session, but you are assumed to know the tool afterwards. Practice more at home if needed.
Note that the tutorial briefly covers topic such as centrality and communities, that will not be covered extensively until Lecture 2.
Done? Get started with the practical part of Assignment 1. You can download the smaller datafiles medium.tsv and large.tsv. If you want to analyze huge.tsv, you will have to get it from the shared folder in the ISSC Linux or LIACS DS lab environment, as stated in the assignment.
In the past, students have expressed interest in additional reading material to help freshen up on skills and knowledge required for this course.
