Abstract

The invention provides a science and technology service-oriented reason graph construction method, device and equipment and a storage medium. The reason graph construction method comprises the following steps: obtaining a science and technology service demand text; preprocessing the science and technology service demand text; performing event extraction on the science and technology service demandtext; performing event relationship extraction on the science and technology service demand file; based on the extracted demand events and the logic relationship between the demand events, establishing a fact graph which is a directed looped graph, with nodes representing the demand events and directed edges representing the logic relationship between the demand events; and calculating an evolution probability between two demand events connected with each directed edge, and adding the evolution probability as a weight value to the directed edge. By constructing a science and technology service-oriented reason graph, the demand event directly related to the user demand and other demand events most closely related to the user demand can be quickly matched, so that the customer demand can bemore effectively perceived.
