Rich Context API integrations for federating metadata discovery and exchange across multiple scholarly infrastructure providers

richcontext.scholapi

Rich Context API integrations for federating metadata discovery and exchange across multiple scholarly infrastructure providers.

Development of the Rich Context knowledge graph uses this library to:

• identify dataset links to research publications
• locate open access publications
• reconcile author profiles
• reconcile keyword mesh

This library has been guided by collaborative work on community building and metadata exchange to improve Scholarly Infrastructure, held at the 2019 Rich Context Workshop.

Installation

Prerequisites:

• Python 3.x
• Beautiful Soup
• Dimensions CLI
• Requests
• Selenium

To install from PyPi:

pip install richcontext.scholapi

If you install directly from this Git repo, be sure to install the dependencies as well:

pip install -r requirements.txt

Then copy the configuration file template rc_template.cfg to rc.cfg and populate it with your credentials.

NB: be careful not to commit the rc.cfg file in Git since it contains sensitive data such as passwords.

Parameters needed in the configuration file include:

parameter	value
chrome_exe_path	path/to/chrome.exe
dimensions_password	Dimensions API password
email	personal email address
repec_token	RePEc API token

Download the Chrome webdriver to enable use of Selenium.

Usage

from richcontext import scholapi as rc_scholapi
import pprint

# initialize the federated API access
schol = rc_scholapi.ScholInfraAPI(config_file="rc.cfg", logger=None)

# search parameters for example publications
title = "Deal or no deal? The prevalence and nutritional quality of price promotions among U.S. food and beverage purchases."

# run it...
meta = schol.openaire.title_search(title)

# report results
pprint.pprint(meta)
print("\ntime: {:.3f} ms - {}".format(schol.openaire.elapsed_time, schol.openaire.name))

API Integrations

APIs used to retrieve metadata:

• OpenAIRE
• EuropePMC
• Semantic Scholar
• Unpaywall
• dissemin
• Dimensions
• RePEc

See docs/enrich_pubs.ipynb for example API usage to pull the federated metadata for a publication.

Testing

To run unit tests for the APIs which do not require credentials:

python test/test.py

To run unit tests for all of the APIs:

python test/full_test.py

To Do

• Dimensions API for dataset metadata
• scrape metadata from web pages PMC/Pubmed, NIH, etc.
• SSRN
• https://paperswithcode.com/?ref=semscholar
• Springer https://github.com/srand525/search_springer/blob/master/SpringerFetch.py
