Abstract:

Gauging the impact of scholars,despite numerous quantitative indicators proposed,remains hard thanks to nowadays gigantic and inflating academic networks accompanied by huge disparity among domains and generations.Data collected from 14 223 183 scholars,126 438 664 papers,533 556 856 references across 310 domains with a time spanning of year 1865 to 2016,suggest universe power-law distributed yearly increased citations of scholars across domains and generations.Turing index then eliminates the inflation via normalizing different scaling parameters in those power law distributions to assess the absolute domain impact of each scholar.Comparison of Turing index among renowned scholars like Nobel,Fields Medal and Turing laureates confirms their equal significance to their dedicated domains despite the vast domain discrepancies in generations and citations.Turing index provides a new way of thinking for cross-domain and cross-generation impact evaluation,and can provide reference for scholars’ impact assessment and national science foundations worldwide.

Key words: impact evaluation, Turing index, big data mining, academic network
