Create ORES dataset for huwiki edits in the last two years or so
Open, Needs TriagePublic


For certain analysis tasks we'll need an easily accessible dataset of ORES goodfaith and damaging judgements (an SQL dump with revision / damaging / goodfaith, presumably). @Halfak says the ores Python package can be used to produce it.

@Halfak says the ores Python package can be used to produce it.

It only seems to have utilities to fetch a given revision ID though, not all revision IDs in a time range, so using the action API seems simpler. That would mean paging through

action: query
generator: allrevisions
garvlimit: max
garvnamespace: *
garvstart: 2019-07-01T00:00:00.000Z
garvend: 2017-07-01T00:00:00.000Z
prop: revisions
rvprop: oresscores

with a continuation-aware client.

My usual process is to generate a random sample of revisions using quarry, and then to score those revisions using the ORES API.

That query will work, but I don't believe there will be any oresscores for revisions that are no longer present in the recentchanges table (30 days old).

I would load the "json-lines" output of this query into the ores score_revisions utility as follows.

cat huwiki_2017-2019_revisions.json | \
  ores score_revisions "" huwiki damaging goodfaith > \

The ORES score_revisions utility will handle batching and parallelization in a way that maximizes performance while minimizing the load on the ORES service.

On Toolforge that command gets OOM-killed after consuming around 1G of memory, if I read the logs right:

Maybe it's trying to store the whole JSON output in memory instead of dumping it sequentially?

Hmm. It's likely the input dataset that is the problem. Do you think we could work with a random sample of revisions instead of the whole huge data file? Alternatively, I could run the same script on a beefier machine that could handle the memory usage.

I can just split the file into chunks. It seems something worth fixing in the ores utility in the long run, though - there are a couple Pythong libraries like JSONAutoArray or jsonstreams that allow streaming JSON output.

@Halfak is there a way to recover the threshold settings for the old (pre-T228078) model? I'd like to check how much the number of likely-damaging etc. anonymous edits have changed due to the update.
