Flagged by gabbar?

[mvexel]

In osmcha I see some of my edits are flagged by gabbar which I suspect is this thing. It is not immediately clear to me by what mechanism edits are flagged and what this means. Some clarification would be wonderful.

👋 @mvexel, thank you for getting in touch.

Yes, changesets with reason Flagged by gabbar do come from gabbar. This is EXPERIMENTAL: UNDER DEVELOPMENT and we will update the README soon with this PR.

Gabbar is an alpha package of a pre-trained binary problematic/not problematic classifier that was trained on manually labelled changesets from OpenStreetMap.

Currently, we are exploring if changesets can be classified as 👍 or 👎 by looking at the number features created, modified and deleted in a changeset. We have a model that given these three values will tell whether a changeset is a 👍 or not based on it's training on the changesets @manoharuss shared with the community in this diary post.

We are at very early stages understanding the behavior of the trained model. The goal is to use all the learning's from the changesets manually reviewed by mapbox/team-data and the OpenStreetMap community on osmcha and build a machine learning based classifier.
