Content analysis made easy. Discourse Network Analyzer (DNA) is a Java-based software for qualitative category-based content analysis. DNA involves two steps: coding statements of actors into categories, and converting these structured data into networks that are readable by Ucinet, visone, NetMiner, Gephi and other network-analytic program packages. The program can extract either bipartite (aliation) networks or adjacency networks.

It is complementary to semantic network analysis applications because it neither relies on algorithms for automatic text processing, nor does it focus on the internal meaning or mental representation of a single text or document. Instead, tags are applied to the text data by manual inspection, thus rendering it more
exible, yet at the same time more work-intensive. DNA can be used to code a large body of text documents and then convert them into graphs.
