MMDS Individual Project 2020/2021

• Second project
• Objective: Creating a Neo4j Graph Database containing a data sample of the online discourse platform debate.org. Additionally, conducting a brief Assortativity analysis of the collected user data.
• Data used: http://www.cs.cornell.edu/~esindurmus/ddo.html
• Graph Database used: Neo4j Version 4.1.1 https://neo4j.com
• Network Analysis tool used: graph-tool https://graph-tool.skewed.de
• Python version used: 3.7
• Further details: 'Alexander_Haberling_Individual_Project.pdf'

1. debateDB_Creation.py
   Extractes data from the Jsons provided by http://www.cs.cornell.edu/~esindurmus/ddo.html

2. Install APOC-Plugin for Neo4j https://neo4j.com/developer/neo4j-apoc/ (4.1.0.2 used in 'debateDB_Exportation.py')

3. debateDB_Exportation.py
   Exports data as GraphML

4. Add the following two lines to the beginning of the resulting GraphML. This ensures a successful GraphTool import
   <key id="labels" for="node" attr.name="labels" attr.type="string"/>
   <key id="label" for="edge" attr.name="label" attr.type="string"/>

5. For Windows: Access GraphTool library via Docker https://graph-tool.skewed.de
   docker pull tiagopeixoto/graph-tool

6. GraphTool_Preprocessing.py
   Prepares data for further analysis

7. GraphTool_Descriptives.py
   Provides a descriptive overview

8. GraphTool_Assortativity.py
   Provides a brief assortativity analysis
