// @namespace     https://acqua.kmi.open.ac.uk/
// @description   ACQUA is looking at the discretised version of linguistic features of each candidate answer and predicts which answer is going to be marked as "accepted". Past knowledge such as user reputation or future knowledge, such as score of the answers is not taken into account. Hence, ACQUA can predict which answer is going to get accepted in real-time settings with minimum resources.
