Keywords:review, recommendation system, collaborative filtration, quality, qualimetry, metric
Paper considers the urgency of the subject of the qualimetric method of the responses analysis. As in 2021 along with the growth of e-commerce sphere, where greater part of purchases occurs after the analysis of the customer’s reviews, where recommendation systems are often used. Main types of psychological profiles of the customersin Internet are analyzed.
Basic types of the recommendation systems are analyzed, the drawbacks of each system are considered. Aim of the research is formulated, it is the improvement of the quality and systematization of its parameters of the reviews analysis for the development of the recommendation systems on the base of qualimetric method and tool. Scientific substantiation on the base of qualimetric approach of the reviews analysis to the algorithm of recommendations on the base of the customer “opinion” – “The Value of Opinion” and instruction of the qualimetric method “Cyclogram of the reviews quality “The Value of Opinion” is carried out.
Scientific task is formulated, it includes: systematization of reviews quality indices, based on qualimetric method; development of new indices of reviews quality on the base of the qualimetric method; possibility of introducing the index “The Value of Opinion” in the new recommendation system of the collaborative filtration, which includes the assessment of the customer’s “opinion”.
The expediency of using qualimetric method for the value of opinion assessment is characterized. The importance of the analysis of the cars reviews is described. Parameters of the qualimetry and problems, solved by means of these parameters in quality cyclogramare considered.
The given research considers new qualimetric approach to measuring the quality of reviews as the part of data, on which the algorithms of modern recommendation systems will be based. The system of the reviews quality assessment in the format “Cyclogram of the reviews quality “The Value of Opinion”” has the set of eight quality indices of the product review. The importance of the study for business-problems is described. Conclusions and final judgements are formulated.
