摘　　要：Purpose:Using the metaphor of"unicorn,"we identify the scientific papers and technical patents characterized by the informetric feature of very high citations in the first ten years after publishing,which may provide a new pattern to understand very high impact works in science and technology.Design/methodology/approach:When we set CT as the total citations of papers or patents in the first ten years after publication,with CT≥5,000 for scientific"unicorn"and CT≥500 for technical"unicorn,"we have an absolute standard for identifying scientific and technical"unicorn"publications.Findings:We identify 165 scientific"unicorns"in 14,301,875 WoS papers and 224 technical"unicorns"in 13,728,950 DII patents during 2001–2012.About 50%of"unicorns"belong to biomedicine,in which selected cases are individually discussed.The rare"unicorns"increase following linear model,the fitting data show 95%confidence with the RMSE of scientific"unicorn"is 0.2127 while the RMSE of technical"unicorn"is 0.0923.Research limitations:A"unicorn"is a pure quantitative consideration without concerning its quality,and"potential unicorns"as CT≤5,000 for papers and CT≤500 for patents are left in future studies.Practical implications:Scientific and technical"unicorns"provide a new pattern to understand high-impact works in science and technology.The"unicorn"pattern supplies a concise approach to identify very high-impact scientific papers and technical patents.Originality/value:The"unicorn"pattern supplies a concise approach to identify very high impact scientific papers and technical patents.
