Science Citation Index Expanded (SCI-E)及其检索技巧

简要介绍了SCI-E网络数据库及特点,并结合实例说明SCI-E数据库的检索技巧及分析功能的应用。

The Consistency Measurement in Document Publications and Citation Using t-Index

Recent time handling uncertainty and its measurement is considered as one of the major issues by data science and applied mathematics researchers. It becomes more complex when the dynamicity exists in data sets. One of the suitable examples is Scopus data sets which changes every time. In this case, precise measurement of consistency in document and citation publications is considered as one of the issues. It becomes more complex when the parameter like h-index and document count can be also manipulated over the period of time. To resolve this issue, a time-based index called as “t-index” is illustrated in this paper with an example. This method measures the randomness in document publication and citation using the average h-index and its entropy measurement.

Current global research landscape on COVID-19 and cancer: Bibliometric and visualization analysis

BACKGROUND Cancer is a severe public health issue that seriously jeopardizes global health.In individuals with coronavirus disease 2019(COVID-19),cancer is considered an independent risk factor for severe illness and increased mortality.AIM To identify research hotspots and prospects,we used bibliometrics to examine the global production of COVID-19 literature published in the field of oncology.METHODS Data on publication output were identified based on the Scopus database between January 1,2020,and June 21,2022.This study used VOSviewer to analyze collaboration networks among countries and assess the terms most often used in the titles and abstracts of retrieved publications to determine research hotspots linked to cancer and COVID-19.The Impact Index Per Article for the top 10 high-cited papers collected from Reference Citation Analysis(RCA)are presented.RESULTS A total of 7015 publications were retrieved from the database.The United States published the greatest number of articles(2025;28.87%),followed by Italy(964;13.74%),the United Kingdom(839;11.96%),and China(538;7.67%).The University of Texas MD Anderson Cancer Center(n=205,2.92%)ranked first,followed by the Memorial Sloan-Kettering Cancer Center(n=176,2.51%).The European Journal of Cancer(n=106,1.51%)ranked first,followed by the Frontiers in Oncology(n=104,1.48%),Cancers(n=102,1.45%),and Pediatric Blood and Cancer(n=95;1.35%).The hot topics were stratified into“cancer care management during the COVID-19 pandemic”;and“COVID-19 vaccines in cancer patients”.CONCLUSION This is the first bibliometric analysis to determine the present state and upcoming hot themes related to cancer and COVID-19 and vice versa using VOSviewer during the early stages of the pandemic.The emergence of hot themes related to cancer and COVID-19 may aid researchers in identifying new research areas in this field.

Understanding more about non-patent references

Non-patent references(NPRs)play an important role in the interaction between science and technology.In this contribution,we compare the characteristics of NPRs traced from patents on"metabolic engineering"to those received by the 10%most-cited articles(cited in scientific publications and excluding NPRs)in the same field.We observe that there is a low rate of co-citing articles between the two groups,and many NPRs have a better citation performance than TOP 10%articles.Our results provide preliminary clues to discover new characteristics of NPRs and to better understand the interface between science and technology.

A causational analysis of scholars' years of active academic careers vis-à-vis their academic productivity and academic influence

Taking the scholarly activities of 73 doctoral program mentors working at the Chinese Academy of Medical Sciences & Peking Union Medical College(the CAMS &PUMC) as a sample of our investigative survey, we tried using such statistical methods as the analysis of variance(ANOVA), factor analysis and correlation analysis to compare the different characteristics of scholarship assessment of Chinese medical scholars as exhibited in their published papers in domestic and foreign journals. Our research findings show that citations per paper and A-index are more suitable for assessing the highly accomplished senior Chinese medical professionals(e.g. academicians) for their domestic and international scholarship attainment. In contrast, the m-quotient is not deemed appropriate to assess their academic influence both at home and abroad. Upon our further analysis of 6 evaluative indicators, we noticed that these indicators might be applied in two different aspects: One is from the viewpoint of Chinese scholars' academic influence at home, which has been evaluated mainly from the perspective of 'total' amount and 'average' amount of both publications and citations. The other is from their academic impact embodied by the means of documents retrieved from the Web of Science, which is mainly assessed from the two viewpoints of publications and citations. It is suggested that the accumulated time-length of a given scholar's active engagement in professional practice in a specific subject area be taken into consideration while assessing a researcher's performance at home and abroad.

Improvement analysis of article quality in World Journal of Gastroenterology during 2008-2012
