Abstract
Citedness score is a widely accepted metric for the quality of scholarly literatures, therefore, the forming calculation and corresponsive consequence of citation counts becomes of importance for academic researchers, especially for the research assessment. However, the distinction of citedness score exists in heterogeneous information systems resulted from considerations for system construction and development, such as purpose, procedure and policy of data processing, and that would bring various meanings and impacts for citedness score. This paper aims to examine the distinctive factors and results on calculation of citedness score of scholarly literatures between Science Citation Index Expanded and Scopus by adoption of comparison as research methodology. In this empirical study, we selected 372 research papers from research grant publications of the College of Engineering at Tamkang University as research subject to test the citation counts from SCIE and Scopus simultaneously. As a consequence, one may generalize that four factors heavily impacts on the different citedness scores between SCIE and Scopus as follows: coverage of collected data, integrity of cited references, quality of citation record and citation pointer between citing and cited references.
