Quantitative experiment for profiles of the users of the “International congress conference «Information technologies in education»” portal. Results of experiment have confirmed adequacy of the offered models. The offered detail level of model and methods of its representation are directed to further improving of a pertinent of all personalisation algorithms. This study was financially supported according to Federal Target Program “Research and development on priority directions of scientific-technological complex of Russia for 2014-2020” (grant â„– RFMEFI57614X0068).
