Statistics

At first, the goal of the project was to achieve 90% coverage of corpora used. It turned out to be a challenging task for three months of work, partly because of the peculiarities of Slavic morphology and morphophonology and the lack of available bilingual electronic dictionaries (and poverty of the latter). As a result, starting from the end of July our main task was to lowering the number of mistakes than on achieving high coverage.
