Quantitative indicators of CSCD journal list

IndicatorsDefinition
JIF (excluding self-citations) Calculated by dividing the number of citations to the journal from other journals in the 6th year by the number of articles published in that journal in the previous 5 years. 
Hot index Taking 10 years as the statistical window, the hot index is defined as the ratio of the number of highly cited papers published by the journal to the total number of highly cited papers in the given discipline the journal belongs to. 
Eigenfactor score Calculated based on the number of times articles from the journal published in the past 5 years have been cited in the JCR year (exclude self-citations). 
Article influence score Calculated by multiplying the eigenfactor score by 0.01 and dividing by the number of articles in the given journal in the past 5 years, normalized as a fraction of all articles in all publications. It is used to track the influence of a journal at the single article level. 
Diffusion index The ratio of the number of citing journals to the total number of journals in the CSCD. 
Excellent index The ratio of the average received citations of a journal to the average received citations of the given discipline the journal belongs to. 
Utilization index The ratio of the number of noncited articles to the total number of published articles in the journal. 
Cross-citation index The coefficient of skewness of the distribution of the citation journals received from other journals. The index measures the skewness of the distribution of the journal’s citation data. The larger the value, the more frequent the cross-citation behavior.
