Abstract

fetched live from OpenAlex

Many working professionals commute via public transit, yet they have limited tools for learning about their urban neighborhoods and fellow commuters. We designed a location-based game called City Explorer to investigate how transit commuters capture, share, and view community information that is specifically tied to locations. Through a four-week field study, we found that participants valued the increased awareness of their personal travel routines that they gained through City Explorer. When viewing community information, they preferred information that was factual rather than opinion-based and was presented at the start and end of their commutes. Participants found less value in connecting with other transit riders because transit rides were often seen as opportunities to disengage from others. We discuss how location-based technologies can be designed to display factual community information before, during, and at the end of transit commutes.

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.
