rplos is an R package to facilitate easy search and full-text retrieval from all Public Library of Science (PLOS) articles, and we have a little feature which aren’t sure if is useful or not. I don’t actually do any text-mining for my research, so perhaps text-mining folks can give some feedback.
You can quickly get a lot of results back using
rplos, so perhaps it is useful to quickly browse what you got. What better tool than a browser to browse? Enter
highplos uses the Solr capabilities of the PLOS search API, and lets you get back a string with the term you searched for highlighted (by default with
<em> tag for italics).
install.packages("devtools") library(devtools) install_github("rplos", "ropensci")
out <- highplos(q = "alcohol", hl.fl = "abstract", hl.snippets = 5, rows = 10) out[]
## $abstract ##  "Background: <em>Alcohol</em> consumption causes an estimated 4% of the global disease burden, prompting" ##  " goverments to impose regulations to mitigate the adverse effects of <em>alcohol</em>. To assist public health leaders" ##  " and policymakers, the authors developed a composite indicator—the <em>Alcohol</em> Policy Index—to gauge the strength" ##  " of a country's <em>alcohol</em> control policies. Methods and Findings: The Index generates a score based on policies" ##  " from five regulatory domains—physical availability of <em>alcohol</em>, drinking context, <em>alcohol</em> prices"
The new function
highbrow (snickers quietly) automagically creates an easy to digest html page, and opens in your default browser.
Here’s a screenshot similar to what you should see after the last command
highbrow uses the
whisker package to fill in a template for a bootstrap html page to make a somewhat pleasing interface to look at your data. In addition, the DOIs are wrapped in a
<a> tag with a https://doi.org/ prefix so that you can go directly to the paper if you are so inclined. Also note that the
<em> tags (italicized) are replaced with
<strong> tags (bold) to make the search term pop out from the screen more.
Let us know what you think.
