Abstract

fetched live from OpenAlex

The interactive visualization of topic models is a promising approach to summarizing large sets of textual data. Topicks is the working title for a means to visualize topic modelling outputs. Incorporating a radial layout, users can view the relationships between topics, terms and the corpus as a whole. Interacting with topic and term nodes, as well as a related bar chart, provides the user with various ways to manipulate the visualization and explore the data. We describe the visualization and potential user interactions before discussing future work.

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.
