When the President tweets, how do we know who is really behind the keyboard? With a trained Neural Network, we might be able to find out.
Prior to March 2018 Donald Trump had been using an unauthorised personal Android phone in his role as POTUS. Whilst a source of anxiety for his Staff, for journalists and researchers this was particularly useful for distinguishing the words of the President himself, from those of the White House Staff. With Twitter’s API — the gateway Twitter makes available for anyone wanting to utilise their data — providing information on the ‘source’ for each Tweet, it became a fair assumption that if the ‘source’ was Android, it was pure Trump.
However as you can see from the following chart that maps the month of the tweet (on the x axis) by the frequency of tweeting (on the y axis), around March 2017 activity from Android drops off, and iPhone activity picks up.
