The technique and program units of data preprocessing in DES documents on the basis of methods of feature selection and feature extraction have been developed. The architecture of neurocomputing complex for compression and visualization of multidimensional data and processing of the lexical and semantical information in DES documents has been created, the non-iterative neural network algorithms for compression of multidimensional data on the basis of model of geometrical transformations have been developed. The technique of using neural network complex for compression and visualization of multidimensional data and processing of the lexical and semantical information in existing DES has been developed. The test researches of program units for realization of statistical and neural network methods of the automated filtration and classification of the lexical and semantical information in DES documents on Edu and Moodle platforms has been carried out.
