The Russian UNL Language Center is organized by two institutions, the Institute for Information Transmission Problems (IITP) of the Russian Academy of Sciences (Moscow) and STAR SPB Ltd. (St. Petersburg), which have been participating in the UNL project from the very outset.
The UNL-Russian Deconverter implemented on this website has been developed by the Laboratory of Computational Linguistics of IITP (LCL), while STAR SPB is responsible for the maintenance and user support of the Language Server.
The LCL was founded in the 1970s. A group of Russian linguists, mathematicians, and software developers came together to design a fully operational formal model of language, which was called ETAP. The theoretical foundation of the system was the Meaning <-> Text linguistic model by Igor Melcuk and the Integral Theory of Language by Jurij Apresjan.
At present, the LCL is engaged in various research activities, most of which are carried out within the framework of a multifunctional NLP environment, ETAP-3, the latest version of ETAP. ETAP-3 consists of several modules, including a bi-directional English-Russian/Russian-English MT system and an embedded UNL-Russian Deconverter.
