Method and device for determining abnormal transaction process of electronic commodities

Abstract

The invention discloses a method for determining the abnormal transaction process of an electronic commodity. The method comprises the steps of: for each electronic commodity, extracting the historical transaction data of the commodity within specified time duration in the past from the historical transaction data recorded in a commodity transaction database; according to each transaction feature which is predetermined to be extracted, extracting a corresponding transaction feature value from the extracted historical transaction data of the commodity within specified time duration in the past; according to a data classification principle corresponding to the corresponding conditions which are satisfied by the extracted transaction feature values simultaneously, taking the volume of transactions of the commodity predicted by one type of historical transaction data corresponding to the data classification principle as the predicted volume of transactions of the commodity within the specified time duration in the past; extracting the actual volume of transactions of the commodity within the specified time duration in the past from the historical transaction data recorded in the commodity transaction database; and determining whether the transactions of the commodity within the specified time duration in the past are abnormal according to the predicted volume of transactions and the actual volume of transactions of the commodity within the specified time duration in the past.

Description

technical field [0001] The present application relates to the technical field of realizing electronic commodity transactions based on Internet technology, in particular to a method and device for predicting transaction volume of electronic commodities, and a method and device for determining abnormal transaction process of electronic commodities. Background technique [0002] With the rapid development of Internet technology, more and more attention has been paid to the processing technology of electronic commodity transactions based on the Internet environment. Among them, the integrity evaluation system centered on the transaction processing record information of electronic commodities is the basis for the healthy transactions of electronic commodity objects on the entire Internet. On the contrary, hype credit will seriously damage the health of the entire e-commerce transaction processing industry based on the Internet environment Good development. [0003] Specifically,...

Problems solved by technology

[0013] From the introduction of the above prior art, it can be seen that the existing methods for finding abnormal transaction processing processes in the process of electronic commodity transactions mainly have two problems: first, a large amount of electronic commodity transaction data needs to be manually identified, so it needs to consume There are a lot of human resources, which affects the efficiency of finding abnormal transaction processing; second, when analyzing the degree of distinction between the specific processing characteristic value in the normal transaction processing process and the abnormal transaction processing process, it is usually analyzed in a single dimension , that is, generally only one processing feature value is selected, and the corresponding rule is set according to the degree of discrimination of the feature value in normal transactions and abnormal transactions, and based on this rule, it is judged according to whether the feature value of the transaction processing data in this dimension exceeds the threshold Whether there is abnormal transaction processing

However, due to the fact that in the actual electronic commodity trading process, massive transaction processing data information has an extremely complex form of expression, the accuracy of abnormal transaction processing needs to be improved only through single-dimensional processing features. Usually, according to this single-dimensional Feature discovery abnormal transaction processing will miss many abnormal transaction processing processes, which is not conducive to the healthy development of electronic commodity trading technology in the Internet environment
