Abstract
This study evaluates global scientific publications on diatom-based lake paleolimnology from 2014 to 2024, with a focus on Indonesia's contributions, using bibliometric and content analysis of Scopus data. A total of 378 publications were identified, with relatively stable annual output. The Journal of Paleolimnology is the leading publication outlet, and Agricultural and Biological Sciences is the most studied subject area. Canada, the United States, and China dominate in publication volume, with Canadian authors being the most influential. Indonesia's research remains limited to a few lakes (Towuti, Rawapening, and Warna), indicating challenges but also potential for expansion. Keyword analysis revealed seven clusters centered on paleolimnology and diatoms. Underexplored research areas include microenvironment, miocene, modern analogs, modern sediments, nutrient limitation, siliceous components, and Patagonian palaeoenvironments. These themes suggest promising directions such as investigating Miocene microhabitats, improving ecological reconstructions through modern analog comparisons, and studying nutrient dynamics and silica availability, which are crucial for diatom growth and lake productivity. The study's findings aim to inform and enhance paleolimnology research in Indonesia and foster greater international collaboration.

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 distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
