Botometer is a web-based program that uses machine learning to classify Twitter accounts as bot or human by looking at features of a profile including friends, social network structure, temporal activity, language and sentiment. Botometer outputs an overall bot score (0-5) along with several other scores that provides a measure of the likelihood that the account is a bot.

Botometer is not affiliated with RAND. It was selected for this database because it fits our researchers' inclusion criteria.
