The invention relates to the technical field of supply and demand matching, and discloses a
resource supply and demand matching method and device, equipment and a medium, and the method comprises the steps: carrying out the structured semantic analysis of resource demand information submitted by a resource
demand side through a preset resource demand interface, obtaining structured
semantics, generating a visual tag
list according to the structured
semantics, and storing the visual tag
list in a
database; obtaining a
label set obtained by carrying out
label combination by a resource demander according to the visual
label list, and carrying out resource label extraction on
resource information data submitted by a plurality of resource providers through a preset resource providing interface to obtain a resource label list, obtaining a
resource provider list obtained by performing demand matching on the resource label list and the label set based on a dynamic weight matching
algorithm, obtaining response data sent by each
resource provider in the
resource provider list to the resource demand information in a preset
demand response interface, and generating an order contract according to the response data, and the efficiency and accuracy of
resource supply and demand matching are improved.
