【摘要】:h指數(shù)在2005年被提出后就受到了廣泛關(guān)注,由于它的簡(jiǎn)單性與有效性,該指數(shù)得到了廣泛的應(yīng)用,但是隨著應(yīng)用的不斷發(fā)展,人們也會(huì)根據(jù)在應(yīng)用過(guò)程中面臨的實(shí)際問題來(lái)對(duì)該指數(shù)進(jìn)行一定的改進(jìn)。由于傳統(tǒng)的h指數(shù)是建立在被引次數(shù)的基礎(chǔ)上,為了對(duì)論文影響力的反映能夠更為全面,人們建立了多指標(biāo)的h型指數(shù),但是在該指數(shù)的獲取過(guò)程中需要對(duì)影響力指標(biāo)之間的相關(guān)性進(jìn)行考察,因?yàn)樗苯雨P(guān)系到論文影響力以及后續(xù)h型指數(shù)的結(jié)果。本文在考察指標(biāo)數(shù)據(jù)分布狀況的基礎(chǔ)上對(duì)指標(biāo)相關(guān)程度的合理度量進(jìn)行了探討,由此對(duì)多指標(biāo)h型指數(shù)獲取過(guò)程中的相關(guān)性度量進(jìn)行了調(diào)整,同時(shí)在相關(guān)系數(shù)改變的基礎(chǔ)上對(duì)論文影響力的計(jì)算進(jìn)行相應(yīng)調(diào)整,提出了一個(gè)基于Spearman Rank相關(guān)系數(shù)進(jìn)行主成分分析的步驟,并從理論和幾何角度分析了這種思路的合理性。進(jìn)一步地,從得到的論文影響力出發(fā),按照傳統(tǒng)h指數(shù)的獲取過(guò)程計(jì)算出相關(guān)系數(shù)調(diào)整的h型指數(shù),并且對(duì)這種指數(shù)的合理性進(jìn)行檢驗(yàn),結(jié)果顯示相關(guān)系數(shù)調(diào)整的h型指數(shù)與h指數(shù)之間呈高度相關(guān)關(guān)系。再考察相關(guān)系數(shù)調(diào)整前后的h型指數(shù)之間的相關(guān)性,發(fā)現(xiàn)二者之間高度相關(guān),說(shuō)明經(jīng)過(guò)相關(guān)系數(shù)調(diào)整的h型指數(shù)具有一定的可行性,最后對(duì)相關(guān)系數(shù)調(diào)整的h型指數(shù)與h指數(shù)和傳統(tǒng)的h型指數(shù)在學(xué)者和期刊兩類對(duì)象下的評(píng)價(jià)效果進(jìn)行考察。
[Abstract]:H index has received extensive attention since it was proposed in 2005. Because of its simplicity and effectiveness, it has been widely used, but with the development of application, People will also improve the index according to the practical problems in the process of application. Because the traditional h index is based on the number of citations, in order to reflect the influence of the paper more comprehensively. People have established an h type index of multiple indicators, but in the process of obtaining the index, we need to examine the correlation between the impact indicators. Because it is directly related to the influence of the paper and the result of the following h type index, this paper discusses the reasonable measure of the correlation degree of the index based on the investigation of the distribution of the index data. Therefore, the correlation measure in the process of obtaining multi-index h index is adjusted, and the calculation of the influence of the paper is adjusted accordingly on the basis of the change of the correlation coefficient. In this paper, a step of principal component analysis based on Spearman Rank correlation coefficient is proposed, and the rationality of this idea is analyzed from the angle of theory and geometry. According to the traditional process of obtaining h index, the h type index adjusted by correlation coefficient is calculated, and the rationality of this index is tested. The results show that there is a high correlation between the h type index and h type index adjusted by correlation coefficient, and the correlation between h type index before and after correlation coefficient adjustment is found to be highly correlated with that between h type index and h type index before and after the adjustment of correlation coefficient. It is shown that the h type index adjusted by the correlation coefficient is feasible. Finally, the evaluation effect of the h type index adjusted by the correlation coefficient and the h index and the traditional h type index under the two kinds of objects of scholars and periodicals are investigated.
