Attempto Controlled English (ACE) is a type of language used in Artificial Intelligence (AI). It is a simplified form of the English language that makes it easier for computers to understand. It is designed to be easier for computers to understand than normal English because computers have trouble understanding everyday English. ACE is made up of simpler words and shorter sentences. Also, every sentence must have a subject, verb and object, and must be in a certain order. This makes it easier for computers to pick out the important information from the sentence.
