Abstract: The study proposes an economic and mathematical IT service provider selection model requiring no preliminary intellectual processing of inputs in contrast to known models. In addition, this approach is characterized by lower computational complexity in contrast to known topic modeling-based recommendation algorithms and enables taking into account the similarity of various topics.
