geo-analysis

Proof of Concept of geographic analysis of climate related misinformation.

Repo structure is:

• R = #rstats code to be run
• data = local storage of interim data
• output = final storage of images produced & related result

From the technical point of view the most relevant files are:

• /R/001 - dump CS.R which connects to CS SPARQL endpoint and dumps the data to a GeoPackage
• /R/010 - overview dumped CD.R builds on results of script 001 to create a basic visualization of climate related claims (only).
• /R/011 - overview related × unrelated CS.R builds on results of script 001 to create a comparative analysis of climate related and unrelated claims.
• /data/cs_data_dump.gpkg which is the actual data dump (not included in git)

From GIS point of view the most relevant files are:

• /output/spatial overview.png geographical overview of any mention as individual place
• /output/spatial count any.png geographical overview of any mention as count per country or equivalent
• /output/spatial count time.png evolution in time of the count of any mention as count per country or equivalent
• /output/spatial share.png percentage of climate related mentions of total mentions per country or equivalent

Due to the GeoPackage size (~250 MB) it is not practical to be included in git, and the script 001 needs to be executed locally. Takes about 90 minutes to run.
