The invention discloses an innovative scheme matching method, device, server and system. The method comprises the following steps that: according to a standard engineering parameter, establishing a semantic ontology, establishing a corresponding relationship independently between an inventive principle and a patent and between the inventive principle and a historical solution, and finally, forming a TRIZ (Theory of Inventive Problem Solving) contradiction matrix method knowledge network; obtaining inventive creativity requirement description, extracting a non-standard engineering parameter from the inventive creativity requirement description, utilizing the TRIZ contradiction matrix method knowledge network to determine a standard engineering parameter contradiction pair so as to obtain an innovative principle and the patent and the historical solution related to the innovative principle, and calculating and sorting the relevancy between the patent and the innovative principle and between the historical solution and the innovative principle; and taking the obtained historical solution as a training sample, establishing a language model according to keywords and patent information labelled in the training sample, finally, automatically inputting the labelled keywords and patent information into the language model, and automatically generating and outputting an initial solution.
