为了客观评价论文被引率在科技期刊评价中的地位和作用,选取2003年SCI数据库收录的眼科学期刊为研究对象,对其中符合标准的36种期刊的2年被引率、3年被引率、5年被引率、8年被引率和10年被引率进行计算,对不同年限论文被引率与影响因子、5年影响因子、即年指标和特征因子的相关关系做了统计分析。应用前期对8525个眼科医生所做的眼科学期刊影响力问卷调查结果与不同年限论文被引率和传统文献计量学指标做相关分析。结果表明,特征因子明显优于其他指标,影响因子优于5年影响因子;2年和3年论文被引率用于科技期刊评价是合理的,且2年论文被引率优于3年论文被引率。5年以上论文被引率完全丧失了期刊评价作用。
In order to objectively evaluate the status and role of the quoted rate of papers in the evaluation of sci-tech periodicals, ophthalmology journals included in the SCI database in 2003 were selected as the research object. The 36- The annual rate of being cited, the rate of being attracted for eight years and the rate of being attracted for 10 years. Statistical analyzes were made on the relationship between the cited rate and the influencing factors, the five-year influencing factors, the annual indicators and the characteristic factors of different years. The results of questionnaire survey on the influence of ophthalmology journals made by 8,525 ophthalmologists in the early stage of application were compared with the cited rate of papers in different years and the traditional literature metrology indexes. The results showed that the characteristic factors were significantly better than other indicators, and the influencing factors were better than the five-year influencing factors. The two-year and three-year essay cited rate for scientific and technical periodical evaluation was reasonable, and the rate of two- . More than 5 years cited rate of papers completely lost the role of journal evaluation.
