Abstract: A calculation system for predicting a proppant embedding depth based on a shale softening effect is provided, including a sampling test terminal, a scheduling module, a monitoring module, and a calculation module, wherein the scheduling module, the monitoring module, and the calculation module are connected in communication, and the monitoring module is connected to an external operating system through a wireless network, wherein the external operating system is configured to perform a hydraulic fracturing operation and receive a first control signal and/or a second control signal from the monitoring module. The sampling test terminal is configured to test the samples and obtain test data. The scheduling module is configured to determine a target construction parameter.

Abstract: A data recommendation method is described. A first label set corresponding to multimedia data can be acquired. At least one second label set each corresponding to one of at least one to-be-recommended data can be acquired. Each second label set can include at least one label each representing a content attribute of the respective to-be-recommended data. A set similarity between the first label set and each of the at least one second label set can be determined according to label positions in the label tree. Target recommendation data matched with the multimedia data can be determined from the to-be-recommended data set according to the set similarity between the first label set and each of the at least one second label set.
