Abstract

fetched live from OpenAlex

The increasing use of geosocial media in research to draw quantitative and qualitative conclusions about urban environments bears questions<br/>about the consistency of the data across the different platforms. This paper<br/>therefore presents an initial comparative analysis of data from six different<br/>geosocial media platforms (Facebook, Twitter, Google, Foursquare, Flickr,<br/>and Instagram) for Washington, D.C., using population and zoning data for<br/>reference. We find that there is little consistency between the different platforms at small spatial units and even semantically rich datasets have severe<br/>limitations when predicting functional zones in a city. The results show that<br/>researchers need to carefully evaluate which platform they can use for a particular study, and that more work is needed to better understand the differences between the different platforms.

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.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
