Oghma

Oghma is a command-line tool for scraping a citation graph from google-scholar starting from some seminal works. google-scholar will prompt a captcha from time to time even though Oghma uses Selenium and only launches requests every 5 to 10 seconds. In which case a notification will pop-up; once you resolved the capcha, you can press <enter> in the terminal to resume the scraping. Using a Firefox profile can help to remain undercover; being logged in a gmail account in this profile is even better. To install Oghma run:

npm install oghma

Oghma understand the following arguments:

1. --nodes: path to a file containing the nodes of the citations graph, each line is a json string encoding the node.
2. --edges: path to a file containing the edges of the citations graph, each line is an array of integer which indicates the line number of the citers of the node at the current line number.
3. [--delay 5000]: the number of millisecond between request is: delay * (1 + Math.random())
4. [--limit 1000]: the maximum number of citers a single paper can have. There is no use to increase this parameter beyond 1000 since google only provide the 1000th first hits.
5. [--cite 0]: minimum number of citations required to enter the citation graph.
6. [--profile]: path to a firefox-profile

Every time you invoke oghma it will explore the last breadth of the citation graph. Breadth of the citation graph are separated with a line containing null in the node file and the edge file. Example of run:

laurent$ oghma --nodes nodes.json --edges edges.json
Enter an EXACT influencal paper's title [empty line to stop]...
