## Epistemic Network Analysis

Resources on Epistemic Network Analysis (ENA), the ENA webtool, and rENA

#### ENA Demos

**ENA of COVID Press Conferences**

This video:

- Compares press conferences held by Prime Minister of New Zealand Jacinda Ardern and the President of the United States Donald Trump on the novel Coronavirus (SARS-CoV-2)
- Visualizes how ENA networks are constructed

**ENA on the fly demo (Law & Order: Special Victims Unit)**

This video:

- Compares discourse of different detectives discussing a case
- Visualizes how ENA networks are constructed

#### ENA Webtool Videos

#### rENA

**Advanced ENA and rENA, ICQE’20, workshop materials by Zachary Swiecki, Vitomir Kovanovic and Cody Marquart**

This workshop introduces using rENA and combining ENA with other methods. Zip file includes: workshop slides, workshop datasets, r code
