Abstract

fetched live from OpenAlex

With the widespread use of smart phones, the importance of cellphone apps is emerging in our daily lives. The rating of an app impacts the number of downloads which may further influence the spread of the app. In order to explore the underlying behavior of apps’ ratings, a research was conducted analyzing rating related data that involves multifaceted factors. Establishing statistical models such as “Generalized Additive Model” provides a conceptual framework for the study and is instrumental in predicting the missing ratings. A number of conclusions are drawn from these models including identification of the non-linear relationship between log installs and ratings, and the positive relationship between log reviews and ratings given number of log installs.

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.
