The state and evolution of Gold Open Access: A country level analysis
Bibliographic record
Abstract
The newly released refine option of Open Access on the Web of Science platform makes it possible to analyze the article-level OA content across the whole Web of Science database, including more than sixty million documents. In this study, employing the OA filter option of Web of Science, we perform a large-scale evaluation of the OA state of countries from 1990 to 2016. Particularly, for each country, we consider not only the absolute number of Gold OA literature but also the ratio of them among all literature. We compare the rates and evolutions of OA across countries. Our results show that the number of OA articles have increased quickly in the last decades. Currently, one quarter of the Web of Science articles are Gold OA articles; In contrast, in 1990, the percentage of OA articles is less than 8%. Brazil is found to be the most active country in OA publishing. In contrast, Russia, India and China have the lowest OA ratios. In addition, the temporal trend analysis shows that the OA percentage of Brazil has been decreasing dramatically in recent years, while the OA percentages of China, UK and Netherlands have been increasing.

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedLabeled directly by 2 models reading the full record.
