Course details

The course combines both theoretical knowledge about network analysis and hands-on skills on how to conduct such analysis.

This course focus both on the theory and practice of network analysis, perceived broadly as an analysis paradigm to understand interactions between people (social networks), relationships between words in the text (text networks) and so on. As this course has both lectures on more methodological nature and hands-on-laboratories, you should have a working knowledge of R or Python before the first class.

More details (class times, enrollment etc.): see University of Helsinki course website.

Course is taught by Matti Nelimarkka. Office hours, see Matti's website.

Learning objectives and evaluation

The course is evaluated as pass/fail. This is to encourage students to engage with the class without risks to their GPA.

Passing grade requires submitting a final project work using class concepts and techniques to an empirical data.

Before first class

  1. Recap Python or R. You should be able to
    • load a files to program and create a data frame (R) or extract variables (Python) from it.
    • basic manipulations to numeric data (sum, division, etc.) and text (splitting text, combining text)
    • write files
    • use functions
    • You can use for example CodeAcademy or DataCarpentry to fresh you your skills.
  2. Install Anaconda 3.7 to your laptop.

During each class

  • Before the class, read the assigned texts for each class.
  • Bring your own laptop with you.

  • We will spent about one hour of the class to discuss the conceptual bits and another hour working on lab exercises.
