{tweetbotornot2} provides an out-of-the-box classifier for
detecting Twitter bots that is easy to use,
interpretable, scalable, and
performant. It also provides a convenient
interface for accessing the botometer API.
Install the development version of {tweetbotornot2} from
Github with:
## install {remotes} if not already
if (!"remotes" %in% installed.packages()) {
install.packages("remotes")
}
## install from github
remotes::install_github("mkearney/tweetbotornot2")Provide a vector or data frame of Twitter handles and predict_bot()
will return the estimated probability of each account being a bot.

#> screen_name prob_bot feature value feature_descriptionIf you have already collected user timeline data, predict_bot() has no
rate limit. If you donāt already have timeline data, then
predict_bot() relies on calls to Twitterās users/timeline API, which
is rate limited to 1,500 calls per 15 minutes (for bearer tokens) or 900
calls per 15 minutes (for user tokens). Fortunately, each prediction
requires only one call to Twitterās API, so itās possible to get up to
6,000 predictions per hour or 144,000 predictions per day2.

#> 2: 1203840834 netflix_bot 0.569732 0.556587Accuracy of tweetbotornot versus botometer across multiple datasets:
1 The built-in classifier was trained using [up to] the
most recent 200 tweets from each user. That means all tweets older than
the 200th tweet will be filtered out (ignored). It also means that
estimates made on fewer than the most recent 200 tweets are
unreliableāexcept in cases where a user doesnāt HAVE up to 200
eligible tweets. In other words, the classifier should work as expected
if data are gathered via {rtweet}ās get_timeline() function with the
n argument set equal to or greater than 200,
i.e. rtweet::get_timelines(users, n = 200).
2 This is in contrast to botometer, which recently increased its rate limit to 2,000 calls per day (up from 1,000 calls per day).
