Abstract

fetched live from OpenAlex

Every ten years, the U.S. Census Bureau conducts a count and collects information on the U.S. population. As part of this process, the Census Bureau creates a series of nested geographies for proper sampling and counting. As of the 2020 census, the City of Boston, MA contains 5,975 census blocks (defined as any piece of land bounded by streets or water on all sides, and not divided by any streets or water). These census blocks are nested within 581 census block groups, which are themselves nested within 207 census tracts. These geographies are permanent for one decade and are meant to remain semi-permanent from census to census. BARI often uses census geographies as units of analyses in our research since they act as approximations of neighborhoods. Information pertaining to these files can be found in the most recent documentation for the "Geographical Infrastructure for the City of Boston." Note: Census geographies are updated every 10 years, so these geographies will be the most current ones until 2030.

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.
