Robotox is a Twitter bot developed as part of the Por trás do alimento project by Agência Pública and Repórter Brasil, that tweets whenever new pesticides have been authorised by the Brazilian government, for use in the agriculture sector.
Because information on the authorisation of new pesticides is buried deep in daily state journals, this information was hard to access. By making this information easily and publicly available, Robotox provides much transparency on what pesticides have been given state authorisation.
A challenge was to interpret the texts of the daily state journals to abstract information on the authorisation of new pesticides. This requires a type of natural language processing, which is technically difficult.
