The invention discloses a supplier material market price evaluation method and
system based on AI networking search, belongs to the technical field of electronic commerce and
data processing, and provides a double-weight confidence model based on
time sequence fluctuation and statistical deviation, data are grouped according to platform types and suppliers, a
price fluctuation oscillogram is generated for each group of data, and the
price fluctuation oscillogram is calculated. Calculating average price and standard deviation in the group; the global average price is introduced, the confidence coefficient of a
single group of data is dynamically quantified through a normalization formula, low weight is given to high-fluctuation and high-deviation data,
noise interference is effectively suppressed, and the reference of the finally output optimized market price is improved; in addition, structured data with timestamps are generated and the grouping average price and
confidence factor of each platform are synchronously output, so that
purchasing personnel are assisted to transversely compare the quotation rationality of suppliers; and finally, the output optimized market price is fused with multi-source high-confidence data, so that enterprises are helped to accurately grasp the market price interval, and the bargaining capability and the
purchasing efficiency are improved.
