1中美科技产出比较显示文摘该文以科技文献为分析基础,从数量与质量方面比较了中美之间科技发展的差距。数量比较选择了SCI、INSPEC、Ei Compendex三大数据库,而质量比较则是应用了SCI中的引文分析。根据作者以前对中国科技产出的评估,该文选择了30个技术研究领域,全面考察了中国在物质科学、环境、工程和生命科学重点发展方向上论文数量情况。SCI数据显示在几乎所有的技术领域内,虽然中国在论文数量方面增幅很大,但美国仍然处于领先地位(2002-2007)。到2007年,INSPEC数据表明,在大多数技术领域内,中国的科技论文数量赶上或超过了美国;但在生物医学和部分环境科学领域,美国仍然保持着较大的领先优势。Ei Compendex的数据分析结果表明,对于大多数技术领域,到2007年中国的科技论文产量更大;而与日益增长的科研经费恰恰相反,美国发表论文的数量似乎在2005年就已经到达了顶峰。如果不考虑生物医学领域,中国显然已经成为美国的强劲竞争对手。为了对质量进行比较,该文对论文和引文数量进行了归一化处理,但仅限于纳米技术领域(1998-2003年)。结果表明,虽然在过去的10年里美国在质量方面明显地领先中国(以及其他主要纳米技术研究国家),但依然不能改表中国的论文质量持续提升的事实。中国目前已经达到可以与法国、意大利、日本和澳大利亚的论文质量相提并论的地步。Ronald N.

3Quality vs. quantity of publications in nanotechnology field from the People’s Republic of China显示文摘This study evaluates trends in quality of nanotechnology and nanoscience papers produced by au- thors from the People’s Republic of China (PRC). The metric used to gauge quality is ratio of highly cited nanotechnology papers to total nanotechnology papers produced in sequential time frames. The USA is both the most prolific nanotechnology publishing country and most represented country on highly cited nanotechnology papers (both in absolute numbers of highly cited papers and highly cited papers relative to total publications) over the 1998―2003 time frame, based on the SCI/SSCI databases. Some of the smaller hi-tech countries have relatively high ratios (~2) of highly cited papers to total publications (e.g. Denmark, Netherlands, Switzerland). Countries that have exhibited rapid growth in SCI/SSCI nanotechnology paper production in recent years (e.g. PRC, South Korea) had ratios an order of magnitude less than that of the USA for 1998, but by 2003 had increased to about 20% that of the USA (~2.5). PRC and South Korea have climbed in the publications rankings from 6th and 9th in 1998, re- spectively, to 2nd and 6th in 2005, respectively. PRC’s ratio monotonically increased from 0.16 to 0.45 over the 1998―2003 period, and South Korea’s ratio increased from 0.11 to about 0.6 over that same period, indicating their papers are getting more and more citations proportionately. Thus, under rapid growth conditions, PRC and South Korea have been able to increase their share of participation in highly cited papers. As of 2003, PRC and South Korea have ratios comparable to nations like Japan, France, Italy, and Australia but not yet approaching those of the highly cited countries. None of the top ten publications producing institutions are from the USA, while all of the top ten highly cited publica- tions producers are from the USA. Over the 1998―2003 time period, the top six total publications pro- ducing institutions (globally) remained the same, with Chinese Academy of Sciences (which consists of many research institutes) wresting the lead from Russian Academy of Sciences in 1999, and thereafter increasing the gap. Over this same time period, the USA institutions constituted about 90% of the top ten most cited papers list. For Chinese institutions specifically in the period 1998―2003, the nanotech- nology publication leading Chinese Academy of Sciences has maintained an average of about 30% of nanotechnology publications over that time frame. The second tier (in terms of quantity) for the last few years has consisted of Tsinghua University, Nanjing University, University of Science and Technology of China, Peking University, Jilin University, Zhejiang University, Shandong University, and Fudan University. Hong Kong institutions have, on average, been strong in ratio, especially City University Hong Kong, and Hong Kong University of Science and Technology, indicating significant citations.Ronald N.

4Treatment repurposing for inflammatory bowel disease using literature-related discovery and innovation显示文摘Inflammatory bowel disease(IBD)incidence has been increasing steadily,most dramatically in the Western developed countries.Treatment often includes lifelong immunosuppressive therapy and surgery.There is a critical need to reduce the burden of IBD and to discover medical therapies with better efficacy and fewer potential side-effects.Repurposing of treatments originally studied in other diseases with similar pathogenesis is less costly and time intensive than de novo drug discovery.This study used a treatment repurposing methodology,the literature-related discovery and innovation(LRDI)text mining system,to identify potential treatments(developed for non-IBD diseases)with sufficient promise for extrapolation to treatment of IBD.By searching for desirable patterns of twenty key biomarkers relevant to IBD(e.g.,inflammation,reactive oxygen species,autophagy,barrier function),the LRDI-based query retrieved approximately 9500 records from Medline.The most recent 350 records were further analyzed for proof-of-concept.Approximately 18%(64/350)met the criteria for discovery(not previously studied in IBD human or animal models)and relevance for application to IBD treatment.Many of the treatments were compounds derived from herbal remedies,and the majority of treatments were being studied in cancer,diabetes,and central nervous system disease,such as depression and dementia.As further validation of the search strategy,the query identified ten treatments that have just recently begun testing in IBD models in the last three years.Literature-related discovery and innovation text mining contains a unique search strategy with tremendous potential to identify treatments for repurposing.A more comprehensive query with additional key biomarkers would have retrieved many thousands more records,further increasing the yield of IBD treatment repurposing discovery.Ronald Neil Kostoff Michael Brandon Briggs Darla Roye Shores 2020World Journal of Gastroenterology2020,26,33:2
5用文献计量数据解读中国和印度的科技发展显示文摘该文采用SCI/SSCI数据库,对通信联系人中至少含有一位印度/中国人的科技论文进行了文献计量学和计算语言学分析。依据对印度和中国科技文献单独分析的结果,深入地探讨了两国在科技领域的差异。借助不同的分析技术,包括影响因子分析、相关性图解以及文档聚类(传统聚类和模糊聚类),多角度地分析了中国和印度科技文献的基本学科结构体系(主要作者、研究单位等)与主要学科结构(学科重点以及学科重点之间的关系)。第一部分内容介绍了中国科技文献评估,第二部分阐述了印度科技文献评估,第三部分则为印度和中国科研成果的多角度比较。Ronald N.
