Abstract

fetched live from OpenAlex

The advent of user-generated content, crowdsourcing and other forms of lay data generation have led to opposing arguments about the quality and reliability of data in the geoweb,. The main focus of this chapter is an ‘experiment' to test the quality, validity and lay monitoring of volunteered geographic information (VGI) data. Given the growing importance of VGI, in particular its very different sources and potential uses, it is important that we also consider how this movement affects the ways in which we re-envision the pedagogy of geographic education. Accordingly, a sub-theme of this paper focuses on the manner in which the VGI experiment is undertaken: the experiment is run with students as a means of complementing their otherwise technical GIS training with primary research that exposes them to the wider social issues and debates relating to geographic data. We discuss the implications of this research project both for observers of the development of VGI and the pedagogy of GIS teaching and learning.

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.
