Abstract

The invention discloses a query method and device, electronic equipment and a storage medium, and relates to the technical field of space-time big data in a big data technology. According to the specific implementation scheme, the method comprises the steps of a query request sent by terminal equipment is received, the query request is used for requesting to query the dynamic association relationship of a target entity, and the query request comprises an identifier of the target entity and query starting and ending time; determining at least one time sub-bucket to be queried in a query database according to the query starting and ending time, each time sub-bucket storing a dynamic association relationship of a target entity in a time period corresponding to the time sub-bucket; and querying the dynamic association relationship of the target entity in the at least one time bucket according to the identifier of the target entity. Compared with the prior art, the dynamic associated information of the target entity is queried in a time bucket dividing mode, the operand can be effectively reduced, and the query speed of the dynamic associated information is increased.

Description

technical field [0001] This application relates to the field of artificial intelligence, in particular to the field of spatiotemporal big data technology in big data technology. Specifically, the present application provides a query method, device, electronic equipment and storage medium. Background technique [0002] In the context of the popularization of the Internet, various collection devices such as monitoring and checkpoints generate a large amount of user behavior data every day. Among them, the behavior data can include hotel stay behavior, traffic travel behavior, call behavior, express delivery behavior, criminal detention behavior, etc. Based on these behavioral data, the dynamic relationship between various entities can be analyzed to discover the hidden relationship between different people, vehicles, or equipment. Significance. [0003] In related technologies, the query of the dynamic association relationship between various entities mainly adopts a map re...
