Scientometric Analysis of Journal of Biomedical Science Te-Cheng Yu1*, Chung-Yao Wang1, Wen-Chien Kuo1, Yee-Shuan Lee2 and Yuh-Shan Ho1# 1School of Public Health, Taipei Medical University 2Bibliometric Centre, Taipei Medical University - Wan-Fang Hospital Introduction Among 5752 journals indexed by Science Citation Index (SCI) in 2001, 16 scientific journals were issued by Taiwan. Journal of Biomedical Science was indexed by SCI since 1997 and was categorized in research & experimental medicine. It ranked 29th in 75 journals in 2001 with the highest impact factor (1.761) among 16 journals. In 1955, Garfield first mentioned the idea of an impact factor that is a fundamental citation-based measure for significance and performance of scientific journals. It is perhaps the most popular bibliometric product used in bibliometrics itself. In this study, volume 4, issue 2-3 to volume 9, issue 6 was evaluated covering period from 1997 to 2002. A bibliometric analysis was performed to assess the publication pattern concerning authorship, collaboration, origin countries, citation frequency and citation indicator. Methodology The data for this study were based on Science Citation Index (SCI) database on the Institute for Scientific Information (ISI), Philadelphia, PA, U.S.A. The research papers analysis were obtained upon literature search with defined Source Title: Journal of Biomedical Science. Results and Discussion A total of 354 papers were published in Journal of Biomedical Science with 1240 citations from 29 countries during the time span from 1997 to 2002. 82% were dominated by Article, 16% Review, 1.7% Editorial Material and 0.28% Correction. Citation per publication of review was 3.9 times than that of article. Most papers were published by United States and Taiwan contributing 40% and 39% respectively. The results indicated small group was the most often method of collaboration.

The results have suggested publication bias in authors from Taiwan and USA. USA and Taiwan represent a share of 79% of world publications and 80% of world citations in Journal of Biomedical Science. USA has highest publication (40%) and citation (39%) in the world. 66% documents published by 2 to 5 authors as a popular co-authorship. 35% documents has never been cited since it published.
