An Algorithm Summarizes Lengthy Text Surprisingly Well

This post was originally published on this site


Training software to accurately sum up information in documents could have great impact in many fields, such as medicine, law, and scientific research.

“An algorithm developed by researchers at Salesforce shows how computers may eventually take on the job of summarizing documents. It uses several machine-learning tricks to produce surprisingly coherent and accurate snippets of text from longer pieces. And while it isn’t yet as good as a person, it hints at how condensing text could eventually become automated.

The algorithm produced, for instance, the following summary of a recent New York Times article about Facebook trying to combat fake news ahead of the U.K.’s upcoming election:

  • Social network published a series of advertisements in newspapers in Britain on Monday.
  • It has removed tens of thousands of fake accounts in Britain.
  • It also said it would hire 3,000 more moderators, almost doubling the number of people worldwide who scan for inappropriate or offensive content.”
