Abstract

fetched live from OpenAlex

In this era of big data, high volumes of a wide variety of valuable data can be easily generated or collected at a high velocity. As such, big data analysis is in demand in various real-life applications and services (e.g., healthcare) as it helps to find useful information and valuable knowledge that are embedded in the big data. The resulting information and knowledge is usually in textual or tabular forms. Given that "a picture is worth a thousand words", visualization and visual analytics helps. In this paper, we present a system for visualizing smart data-as well as their related information and knowledge-from health data, which in turn supports healthcare analytics.

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.
