[Purpose/significance] The exploration on a more scientific and flexible inventor evaluation scheme can make a more accurate and comprehensive analysis and evaluation of the influence of the inventors. [Method/process] Based on "bibliometrics analysis"and"social network analysis",the InventorRank( IR) model that is used to evaluate inventor’s comprehensive influence is proposed by optimizing NBA( Network-based Allocation) scheme. [Result/conclusion] The IR model can overcome the deficiencies of other algorithms and evaluation indicators,and has a higher degree of division,and more stable and reasonableresult.
