The script prepares the csv files that the cypher queries use to load the citation data into Neo4j.
Originally used
py2neoto load the articles directly from the script but that was very slow.Currently the only reliable citation data is titles. The script initially creates nodes for the articles in the dataset, and then merges cited articles (creates new nodes if the title is new). This leaves the possibility of there being duplicate titles that have the same node. We could try to use citation metadata to separate these but the additional citation metadata is unreliable.
A quick script shows there's a total of 59839 articles and 57099 after removing duplicate titles.
