The Tools of a Machine Grammar of the Russian Language (based on G.G. Belonogov)

The principles and methods of creating program and declarative tools of a machine grammar of the Russian language are considered. These tools were based on original algorithms developed by the scientific team of the staff of the VINITI (All-Russian Institute for Scientific and Technical Information), the 27th Central Scientific Research Institute, Ministry of Defense (Russia) and the Informatics and Management Federal Research Center of the Russian Academy of Sciences (FIC IU RAS). Declarative tools, which are a complex of dictionaries and grammatical tables in machine form, were created on the basis of large-scale studies of large volumes of polythematic textual information (measured in tens of millions of words) using linguistic-statistical methods. The complex of declarative tools consists of grammatical tables and machine dictionaries that include the main types of inflectional and derivational transformations, as well as representative dictionaries of word stems. Unique algorithms of machine grammar of the Russian language were developed through the use of these declarative tools. The described tools are now widely used in a number of industrial information systems for solving complex problems of automatic processing and semantic analysis of textual information.
