1. The researchers created an automated system called "Computer Semiography" to decode Znamenny chants. The system consists of 5 modules: inputting chants into a database, reviewing manuscripts, forming linguistic and translation models, decoding chants, and a music editor. 2. The system can decode chants using either linear or Znamenny notation by applying rules from dictionaries and books. Researchers first build dictionaries from sources then use them to transform manuscripts into a linear notation. 3. The methodology allows producing three main components for decoding chants: a dictionary with translation rules, a translated manuscript version, and language and translation models. The work developed software to input, edit, and view chants in the database
