Abstract: Various embodiments include systems, methods, and non-transitory computer-readable media for identifying and matching influencers with categorized products using multimodal machine learning technologies. Consistent with these embodiments, a method includes identifying an influencer based on a set of criteria; determining a first attribute of the influencer based on context data associated with the influencer; identifying a second attribute of an item; generating a first vector that represents the first attribute of the influencer and a second vector that represents the second attribute of the item; generating a similarity score that represents a degree of similarity between the influencer and the item based on the first vector and the second vector; and causing display of the similarity score in a user interface of a device.

Abstract: An exploitation method and an exploitation well pattern for coalbed methane in a low-permeability coalbed. The method comprises: determining a maximum principal stress direction in a low-permeability coalbed; disposing at least two large-roadway horizontal wells in the low-permeability coalbed; disposing a plurality of production wells on two sides of a horizontal segment of each of the at least two large-roadway horizontal wells, wherein a diameter of each of the production wells is smaller than a diameter of the horizontal segment; exploiting the coalbed methane in the low-permeability coalbed through the at least two large-roadway horizontal wells and the plurality of production wells. Through the horizontal segments of the large-roadway horizontal wells perpendicular to the maximum principal stress direction, it promotes stress release in low-permeability coalbed to form more fracture channels, thereby improving the exploitation efficiency of the coalbed methane in the low-permeability coalbed.
