Online Human-Bot Interactions: Detection, Estimation, and Characterization
Abstract
Increasing evidence suggests that a growing amount of social
media content is generated by autonomous entities known
as social bots. In this work we present a framework to de-
tect such entities on Twitter. We leverage more than a thou-
sand features extracted from public data and meta-data about
users: friends, tweet content and sentiment, network patterns,
and activity time series. We benchmark the classification
framework by using a publicly available dataset of Twitter
bots. This training data is enriched by a manually annotated
collection of active Twitter users that include both humans
and bots of varying sophistication. Our models yield high ac-
curacy and agreement with each other and can detect bots of
different nature. Our estimates suggest that between 9% and
15% of active Twitter accounts are bots. Characterizing ties
among accounts, we observe that simple bots tend to interact
with bots that exhibit more human-like behaviors. Analysis of
content flows reveals retweet and mention strategies adopted
by bots to interact with different target groups. Using cluster-
ing analysis, we characterize several subclasses of accounts,
including spammers, self promoters, and accounts that post
content from connected applications.

What does a feminist internet look like? | Chitra Nagarajan | Opinion | The Guardian
These three companies [FB, Twitter, Google] are indicative of the sector as a whole. There is a problem with ethnicity as well as gender, particularly when it comes to who runs companies. At Google for example, even though white people make up 57% of those in tech positions and 59% of the company overall, they hold 70% of leadership positions. This is despite women spending more time on social media than men globally – 5.88 hours compared to 4.75 hours – and the history of women in computing and technology. It was women like Ada Loveleace after all who were the pioneers of computer programming and women made up over two-thirds of those working at Bletchley Park during the second world war.
