Abstract

fetched live from OpenAlex

The same protein has been observed, through methods of direct assay, to localize to various compartments of the cell. Finding the order in which such subcellular localizations take place contributes toward elucidation of protein pathways and protein-protein interactions. On the other hand, incorporation of the hierarchy of cellular compartments organized as a tree allows a more clear reasoning in terms of the paths taken by proteins that localize to multiple overlapping subcellular sites. In this work, we build an ontology to serve as a knowledge repository for localization of fungal proteins to a hierarchy of major subcellular sites and the order in which such localizations take place. We use this ontology to automatically classify fungal proteins as per their localizations or according to their speciflc characteristics. Finally, we develop a menu-driven user interface to interact with the constructed ontology. Based on a template of application scenarios, user selections are translated into executable queries to be posed to the system.

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.

Not 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.
