Commodity comment public opinion-based cross-border product quality risk fuzzy prediction method

Abstract

The invention discloses a commodity comment public opinion-based cross-border product quality risk fuzzy prediction method. The method comprises the steps of collecting data; preprocessing the data, wherein the data preprocessing comprises text analysis and data conversion; establishing a commodity sub-word bank and a product quality comment word bank; establishing a commodity classification library; carrying out reference risk grade labeling on a product according to sampling inspection report data of inspection and quarantine and risk evaluation standards; analyzing commodity comment publicopinions, and extracting negative comments in comment information; analyzing negative comment quality relevancy, and calculating the number of quality negative comments of commodities in the same category; building a risk prediction model, wherein the risk prediction model comprises a membership function and a BP neural network; and outputting a prediction risk grade, and predicting a product quality risk according to the prediction risk grade. According to the prediction method, through the judgment of a user to quality evaluation contents of a type of commodities, the quality of the commodities and the commodities in a big-class commodity catalogue can be known from the side.
