If the heat characteristic value of a product is greater than the preset heat characteristic critical value, the product is a best-selling product on the Internet; In step S2, the process of obtaining the heat characteristic value corresponding to each product includes: The heat characteristic value of each product within the preset time interval is calculated by the above formula; Among them, there are a total of W product names screened in step S1, and the W product names are numbered in sequence, k∈[1,W], E k is the heat characteristic value of the kth product, [t1, t2] is the preset time interval, P k (t) is the frequency characteristic curve of the kth product, R k (t1) is the cumulative sales volume of the kth product at time point t1, R k (t2) is the cumulative sales volume of the kth product at time point t2, τ1 and τ2 are the weight coefficients of the factors affecting the heat characteristic value; The process of calculating the correlation coefficient between each Internet best-selling product and the characteristic value of the non-human factors that affect it includes: It is determined that there are D best-selling products on the Internet, and each best-selling product on the Internet is numbered in sequence, y∈[1,D]; In the process of analyzing the heat characteristic values of each product through the supervision and evaluation module, multiple heat characteristic values E of the yth best-selling Internet product are taken in the preset time interval. y (t l ); The change function of the characteristic value of non-human factors affecting the yth product is preset as f y (t); Substitute the intermediate values of each preset time interval into the non-human factor characteristic value function f that affects the product y (t), obtain the f corresponding to the middle time nodes of multiple preset time intervals y (t l ); The correlation coefficient r between the heat characteristic value of the yth Internet best-selling product and the characteristic value of the non-human factors affecting it is calculated by the above formula y ; Among them, H is the number of collected product heat feature values and their corresponding non-human factor feature values, l∈[1,H], E y (t l ) is the heat characteristic value of the yth best-selling Internet product in the lth preset time interval, is the average of the H heat feature values of the yth best-selling Internet product, f y (t l ) is the non-human factor characteristic value corresponding to the lth preset time interval of the yth Internet best-selling product, is the average value of the H non-human factor feature values of the yth best-selling Internet product; The process of obtaining the characteristic change function of non-human factors affecting the y-th product includes: The non-human factor characteristic change function f that affects the yth product is calculated by the above formula y (t); Among them, V y is the number of non-human factors affecting the yth product, x∈[1,V y ],g y·x (t) is the function value of the xth non-human factor affecting the yth product over time, θ y·x is the weight coefficient of the xth non-human factor affecting the yth product; The process of determining whether each Internet best-selling product is a new or popular product includes: The correlation coefficient r corresponding to each Internet best-selling product y The correlation coefficient with the preset standard value r sth Make a comparison; If | r y |≥r sth , indicating that there is a certain degree of correlation between the product and the characteristic values of non-human factors that affect it, and it is not a new or internet-famous product; If | r y | <r sth , indicating that there is no certain degree of correlation between the product and the characteristic values of non-human factors that affect it, and it is a new and internet-famous product.
