Author to Wordcloud

Created: 2015-12-02 18:00:15      Last updated: 2015-12-07 14:51:04

This small workflow demonstrates how to connect to and use Europe PMC (http://europepmc.org/RestfulWebService). The workflow searches the publications of an author, extracts the abstracts, counts the word frequencies and plot a wordcloud using the R package of the same name. The Rshell plot_wordcloud also applies text mining operations (transformation to lower case, removing punctuation, stripping whitespace and removing English stopwords) using the R package tm.

Thumb
This small workflow demonstrates how to connect to the new (August 2015) version of Europe PMC (http://europepmc.org/RestfulWebService). Changes from previous versions include the addition of a pageSize parameter, allowing the client to request up to 1,000 records at once. If this would still not be sufficient, the offSet paremeter can be used to retrieve data in chunks of 1,000 records and the Flatten List service used to concatenate the results.
