A comprehensive manual for the Discourse Network Analyzer is available. The documentation includes a beginner's tutorial with many screenshots, a version history, frequently asked questions (FAQ), and a description of the algorithms and options in the network export window.
The following sample file is an excerpt from a dataset which was used by Fisher, Leifeld and others to analyze climate change discourses in the U.S. Congress (see publications for details). The beginner's tutorial in the manual is based on this dataset. Please download it if you plan to use the tutorial.
