Problems solved by technology

[0003] At present, the research on the technology service industry mainly focuses on the construction of the technology service platform, and there is a lack of research on the relationship between technology services, especially the evolution law
On the other hand, insufficient attention has been paid to the research on technological services that respond to user needs, so that service matching cannot well meet user preferences.

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.

Description

technical field [0001] The present invention relates to the field of scientific and technological services, and in particular, the application relates to a method, device, equipment, and storage medium for constructing an event graph for scientific and technological services. Background technique [0002] Science and technology service refers to an emerging industry that uses scientific and technological knowledge, technical equipment and other related resources to provide intellectual services to the society. The State Council's "Several Opinions on Accelerating the Development of the Science and Technology Service Industry" pointed out that my country's science and technology service industry is based on professional technology services such as research and development, technology transfer, inspection, testing and certification, business incubation, intellectual property rights, technology consulting, technology finance, and science and technology popularization. Comprehens...
