The PROMT engine was initially developed for rule-based machine translation (RBMT), but since 2011, PROMT has also offered enterprise solutions based on statistical machine translation (SMT) as well as a PROMT DeepHybrid translation engine.


RBMT is built on the linguistic description of two natural languages (bilingual dictionaries and other databases containing morphological, grammatical, and semantic information), formal grammar, and translation algorithms. Translation quality depends on the volume of linguistic databases (dictionaries) and on the depth of the natural languages description; i.e., it requires consideration of the maximum grammatical structure features.

PROMT has been developing rule-based engines for 20+ years and this is a proprietary technology that combines translation algorithms and dictionaries created by PROMT. Currently, PROMT dictionaries and algorithms support hundreds of inflexion types and thousands of syntactic and semantic characteristics.
