Organized Access to the Ibero-American Quality Journals: The PPL Experience
Bibliographic record
Abstract
Abstract: Latindex has created a portal of portals (PPL) aimed at providing free and open organized access to the literature published in Ibero-American scholarly journals. A report on the initial experience with the PPL is presented, with a critical overview of the main features and shortcomings found in the harvesting process. Our findings raise the need for additional information sources in Ibero-America and for the portals to adopt and adhere to technical and editorial standards. Further, the coverage of journals by different systems providing quality indicators is analyzed, based on case studies of journals produced in two countries with different degrees of development. This analysis highlights the relevant role that PPL can play in support of Ibero-American journals and as a tool in evaluation processes.Résumé : Latindex a créé un portail de portails (PPL) destiné à fournir un accès organisé libre et ouvert à la littérature publiée dans les journaux scientifiques ibéro-américains. On présente un rapport sur l'expérience initiale, avec une revue critique des caractéristiques principales et des problèmes rencontrés durant la récolte. On montre la nécessité de sources d'information additionnelles dans la région et que les portails adoptent et suivent des normes techniques et éditoriales. De plus, sur la base d'études de cas dans deux pays de degrés de développement différents, on analyse le traitement de journaux par des systèmes fournissant des indices de qualité. Cette analyse met en évidence le rôle que le PPL peut jouer en plus comme appui des journaux ibéro-américains et comme outil de processus d'évaluation.
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.
