Overview

Google Scholar does not have its own API provided by Google. This page is dedicated to investigation into alternative methods for parsing and crawling data from Google Scholar.

Existing Libraries

A couple of Python parsers for Google Scholar exist, but they do not satisfy everything we need from this crawler.

Scholar.py

The scholar.py script is the most extensive command line tool for parsing Google Scholar information. Given a search query, it returns results such as title, URL, year, number of citations, Cluster ID, Citations list, Version list, and an excerpt.

For example, once scholar.py is downloaded and all necessary components are installed the following command:

python scholar.py -c 3 --phrase "innovation" 

produces the following results:

Scholarly

Another parser of potential interest is scholarly. However, it produces less information than the scholar parser does.
