The research on the effects of study is hindered by the limitations of the techniques and methods of registering, measuring and assessing the actually formed knowledge. The problem has been solved using latent semantic analysis for comparison and assessment of scientific texts and knowledge, expressed in the form of free verbal statements. Education at higher schools has the specific objective ...
