A feature analysis of the materials published from J-STAGE: A case study for the materials in the information science field

Preliminary research is conducted that analyzes characteristics of the materials published from J-STAGE and of their contents in order to get useful information for improvement of J-STAGE. By using 106 materials in the information science field as the sample, distributions of several features (material sizes, accessibility situations, material types, article languages, etc.) are analyzed and the characteristics of the materials investigated, models of material categorization, and subjects for extended research in future are discussed. For a full-scale survey, we concluded that it is necessary to refine the metadata, establish criteria for comparison with other journal collections, and conduct a more detailed analysis of J-STAGE usage data.
