Methods of reproduction of causal models from data which are capable to provide the forecast of consequences of actions (interventions) in the environment are developed, and the procedure of calculation of the causal forecast is described. A semantic model of the image is developed and the implementation of the machine learning model for solving the problem of automatic construction of such a model for the input image is described. The generalized classification of big data metadata is determined, and the main methodological aspects of the process of their semantic annotation are offered. A method for obtaining background knowledge from semantized Wiki-resources has been developed. A method of analysis of natural (Ukrainian) texts based on latent-semantic analysis has been developed.
