Mapping the UN Second World Ocean Assessment: Challenges and Opportunities
Bibliographic record
Abstract
Our project aims to use the reports from the United Nations Second World Ocean Assessment (WOA II) to build a global corpus of ocean research literature using citation and search-based information retrieval approaches. In this first step towards this larger goal, we extracted references from the WOA II, collected their identifiers with Crossref and OpenAlex, and used VosViewer and Gephi to create and visualize citation-based networks of the literature mobilized in the reports. Our preliminary analysis shows that 76% of references had DOIs, with a significant portion lacking adequate metadata, highlighting the need for metadata enrichment, especially for chapters with references lacking this information. Despite these challenges, the maps show promise for reflecting the structure of the WOA II, identifying clusters, and developing search strategies to retrieve a more comprehensive set of literature on these topics.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
