摘　　要：[目的/意义]科技评价对于优化资源配置、提高科研能力具有重要参考作用,建立科学合理的科技评价体系具有非常重要的意义,在生命科学与生物技术迅猛发展的当下,科研产品层出不穷,学科日益交叉会聚,我国的科研创新亟需一套具有中国特色的原创评估体系及方法。[方法 /过程]基于此,中国科学院上海生命科学信息中心(生命健康科技智库)依托生命科学、基础医学及相关学科领域的专家和学者,聚焦"生命科学与基础医学"领域,结合本领域的学科特点,立足专家评议、期刊影响力、领域权重、第一作者/通信作者权重等定性和定量指标,提出"π指数"的概念和算法。[结果 /结论 ]每年发布生命科学与基础医学领域全球机构π指数分析报告、5年π指数趋势分析报告、国家重点实验室π指数分析报告,2018年还尝试了探索基于多层引文和支持向量机相结合的"单篇论文学科分类"方法,对单篇文献进行学科分类,并推出了"学科领域π指数分析报告"。本文对π指数的评价方法以及2018年发布的π指数系列报告进行了分析和阐释。[Purpose/significance]Scientific evaluation is important for optimizing resources allocation and improving the research ability,therefore,it is of a great significance to establish a scientific and reasonable evaluation system.With the rapid development of life science and biotechnology,scientific research achievements are endlessly emerging and disciplines are increasingly converging.In China,it is extremely urgent to build an original evaluation system and method with Chinese characteristics.[Method/process]πindex,first released by Shanghai Information Center for Life Sciences(Life&Health Technology Think Tank),focuses on the area of life science and basic medicine,relies on the experts in the life science and basic medicine field,combines the problems and characteristics of the existed evaluation index,bases on the qualitative and quantitative factors,i.e.,expert review,journal impact,first and corresponding author weight.[Result/conclusion]The 2018 Reports ofπIndex include four individual parts:annualπindex,5-year trend analysis,China’s state key laboratory analysis,and subject analysis,which is a newly developed report based on multi layer reference and support vector machine.This paper detailedly illustrates the evaluation method and 2018 Reports ofπIndex.
