Abstract

The comprehensiveness of database is a prerequisite for the quality of scientific works established on this increasingly significant infrastructure. This is especially so for large-scale text-mining analyses of scientific publications facilitated by open-access full-text scientific databases. Given the lack of research concerning the comprehensiveness of this type of academic resource, we conducted a project to analyze the coverage of materials in the PubMed Central Open Access Subset (PMCOAS), a popular source for open-access scientific publications, in terms of the PubMed database. The preliminary results show that the PMCOAS coverage is in a rapid increase in recent years, despite the vast difference by MeSH descriptor.
