Generate PageRank from citation data

First generate or download the citation links, e.g. using datacapsule-occ.

Then run:

./pagerank.sh \
  --links-path=data/doi-citation-links.csv \
  --pagerank-output-path=data/doi-citations-pagerank.csv \
  --source-column=citing_doi \
  --target-column=cited_doi

The output will be data/doi-citations-pagerank.csv with the following columns:

• citing_doi (or name specified by source_column)
• pagerank - the file will be sorted by that value (descending)
• incoming - number of incoming connections
• outgoing - number of outgoing connections
