Abstract:[Purpose/significance] In order to solve the problems about the heavy load of sci-tech novelty search tasks and the understaffed work force for it in China Southern Power Grid Company, according to the China Southern Power Grid Company’s problem of existing sci-tech novelty search method can"t meet the demand of sci-tech novelty search work, by using Intelligent technology and Information technology, we design and implement an Intelligent Sci-tech Novelty Search System. [Method/process]By analyzing the existing system in China, we put forward the design objective, build the system Requirements model and process model for this Sci-tech Novelty Search System, design and implement the function of "one-stop" novelty search, novelty assessment, “self-help” novelty search and etc.[Result/conclusion]This sci-tech novelty search system achieved the design goals, was accepted by the Acceptance Committee, have reduced the work pressure of novelty searchers, have improved the efficiency and quality of sci-tech novelty research of this company, improved the overall level of the China Southern Power Grid Company’s sci-tech novelty search work.
