Today, only a few companies use statistical machine translation commercially, e.g. Omniscien Technologies (formerly Asia Online), SDL / Language Weaver (sells translation products and services), Google (uses its proprietary statistical MT system for some language combinations in Google's language tools), Microsoft (uses its proprietary statistical MT system to translate knowledge base articles), and Ta with you (offers a domain-adapted machine translation solution based on statistical MT with some linguistic knowledge). There has been a renewed interest in hybridisation, with researchers combining syntactic and morphological (i.e., linguistic) knowledge into statistical systems, as well as combining statistics with existing rule-based systems.
