Match Authors in Scopus automatically with sosia¶
sosia (Italian for doppelgänger) finds researchers that are similar to another one. Use the matching researcher as a control in Diff-in-Diff anlyses. sosia is developed and described by econometricians for scientists of science.
sosia does not pre-compute annual characteristics to find controls. Instead, sosia searches the entire Scopus database via pybliometrics. Configure both–and let sosia find a match for you.
Example¶
Install sosia from PyPI using the console or command line interpreter:
$ pip install sosia
In Python, set up sosia (and eventually pybliometrics) and search for similar scientists using their Scoups Author Profile IDs.
>>> import sosia
>>>
>>> sosia.create_fields_sources_list() # Necessary only once
>>> sosia.make_database() # Necessary only once
>>>
>>> stefano = sosia.Original(55208373700, 2019) # Scopus ID and year
>>> stefano.define_search_sources() # Sources similiar to scientist
>>> stefano.define_search_group() # Authors publishing in similar sources
>>> stefano.find_matches() # Find matches satisfying all criteria
>>> print(stefano.matches)
>>> ['55022752500', '55810688700', '55824607400']
>>> stefano.inform_matches() # Optional step to provide additional information
>>> print(stefano.matches[0])
