"Controlled Natural Languages are subsets of natural languages whose grammars and dictionaries have been restricted in order to reduce or eliminate both ambiguity and complexity. Traditionally, controlled natural languages fall into two major categories: those that improve the readability for human readers, in particularly for non-native speakers, and those that improve the computational processing of a text."
