The paper describes a new class of tasks with complicated structure. 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.
