A simplistic method of topic identification is proposed. The topic index is calculated as a real number, and can be used for comparing with a threshold when validating the topic identity of the content. The approach is based on the assumption of having a set of characteristic words for the estimated topic and yields a simple implementation which is suitable both for the tasks where the high precision is not required and for solving more complex problems, where it can be used in the context of preliminary topic evaluation in a multi-level topic identification process.

There has been represented a criterion of optimal selection of the polymer viscosity temperature dependence by measurement data of its actual viscosity with applying the minimization of functional – distance between presumptive temperature dependence and the patterned. It has been proffered the software support in the form of public MATLAB-module for searching the optimal equation of viscosity temperature dependence by the represented criterion.
