The subject domain of these tasks is formed from a variety of information sources, distributed in the global environment. Properties of tasks with complicated structure and the relevant properties of the subject domain are researched in this work. Dynamic model of the subject domain construct using the ontological approach is proposed. , . “ ” , . . [1]. IT- , , ( ), , , [2]. , : , , . , . – , . , [3]. , , , , . . . , ( , , ) . , – . , . , .
