概要	Scopus, owned by Elsevier, is the world's largest abstract and citation database covering peer-reviewed journals, conference proceedings, and book chapters across all scientific disciplines. Launched in 2004, Scopus now indexes over 37 million documents from more than 6,500 journals, with expanded coverage of open-access publications and emerging regional journals. Scopus provides researchers and institutions with comprehensive citation tracking, field-normalized impact metrics (CiteScore, SJR, SNIP), and analytical tools for literature discovery, research evaluation, and institutional benchmarking.	SCImago Journal Rank (SJR) is a prestige-weighted metric measuring journal citation impact based on Scopus data, developed by SCImago Group (a Spanish research consortium) in 2010. Unlike raw citation counts, SJR values citations from high-prestige journals more heavily than those from lower-prestige journals, similar to Google's PageRank algorithm. This prestige weighting approach accounts for field-specific citation cultures and provides fairer cross-discipline comparisons than raw impact factor. SJR is widely used for journal ranking, quality assessment, and publication targeting, complementing traditional Impact Factor with a prestige dimension.
