Embodiment Construction

[0028] In the field of e-commerce, related technologies can recommend related products to users based on their historical behavior data. For example, if a user searches for a certain product on a website, the related method can calculate the classification and characteristics of the product that the user searches for, and further recommend similar products or another related product to the user based on the classification and characteristics of the product. It is impossible to predict a series of behaviors or events that users will take place around the same product. The event prediction method provided in this application pre-trains to obtain event transition maps corresponding to various events, and when the current event is obtained, the most likely event after the current event occurs is determined according to the event transition map corresponding to the current event. Use this method to predict a series of behaviors or events that occur around the same commodity.

Abstract

The invention discloses an event prediction method and device, and the method comprises the steps: firstly obtaining a current event and the field of the current event; then, obtaining an event transfer map corresponding to the field, wherein the event transfer map is a transfer rule between different events; and finally, searching a target event type set to which the event type corresponding to the current event can be directly transferred from the event transfer map corresponding to the field. By utilizing the method, the type of an event to be generated in the next stage after the current event occurs can be predicted; for example, the event or behavior of the user in the next stage can be effectively predicted by utilizing the method.

Description

Technical field [0001] The invention relates to the field of computer technology, in particular to an event prediction method and device. Background technique [0002] With the rapid development of computer network technology, computer networks have basically become an indispensable part of people's lives. People communicate through the network, obtain the information they need, and trade commodities. [0003] For example, in the field of e-commerce, in order to improve user experience, products are recommended to users based on historical behavior data. Specifically, according to the user's retrieval behavior of a commodity, the commodity feature calculation is performed, and the user's demand for similar commodities or another commodity in the next stage is calculated according to the characteristics and classification. For example, if a user has browsed a certain brand of "air purifier" on an e-commerce website, the website recommends other brands of "air purifier" or other bra...
