Bibliographic record
Abstract
This bibliometric analysis examines the scientific literature development in poppy alkaloids and morphine biosynthesis from 1980 to 2024. Using data from 845 Web of Science publications, we conducted comprehensive analyses including annual scientific production, international collaboration networks, keyword analysis, citation patterns, and thematic mapping. Our findings reveal steady growth in scientific output since the 1980s, peaking at 45 publications in 2016. The USA, Canada, UK, Germany, and Australia emerge as the most productive and influential countries in international collaboration networks. Citation analysis identifies Facchini (1996), Morishige (2000), Liscombe (2007), and Hagel (2010) as the field's most influential reference points. Thematic mapping identifies "opium poppy," "molecular-cloning," and "expression" as motor themes driving the field, while "biosynthesis," "alkaloids," and "morphine" constitute core themes. Word cloud analysis shows "Papaver somniferum" as the most frequently used term (frequency: 76), representing 8% of the total research focus according to treemap analysis. This study provides a comprehensive mapping of the scientific structure and developmental dynamics in poppy alkaloids and morphine biosynthesis research, offering valuable insights for identifying research gaps and predicting future directions in this interdisciplinary field.

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 itClassification
machine, unvalidatedLabeled directly by 2 models reading the full record.
The models disagree on parts of this classification; every voice is preserved in the section at the end of the page.
