I moved Tumbuka Wikipedia (tum) to an earlier batch as they are interested by the feature.

21/21 models were trained successfully in the 17th round of wikis.

Model evaluation has been completed and below are the backtesting results:

CCing @MGerlach, in case he would like to add comments on the backtesting evaluation.

The conclusion on the backtesting results is that most of the languages look fine besides:

• tiwiki (0.54), tkwiki (0.74), urwiki (0.62) have a precision lower than the recommended one (0.75)

Talked to @MGerlach about these results and agreed that tkwiki should be published but tiwiki and urwiki shouldn't.

@kostajh, we published datasets for all 19/21 models that passed the evaluation in this round.

I ran this script for adding the link-recommendation task type and populating the excluded sections entries:

PHAB=T308143
for WIKI in tkwiki tlwiki tnwiki towiki tpiwiki trwiki tswiki ttwiki twwiki tywiki tyvwiki udmwiki ugwiki uzwiki vewiki vecwiki vepwiki vlswiki vowiki; do
    ORIGIN=`mwscript getConfiguration.php $WIKI --settings 'wgCanonicalServer' --format json | jq --raw-output '.wgCanonicalServer'`
    mwscript extensions/GrowthExperiments/maintenance/changeWikiConfig.php $WIKI \
            --page MediaWiki:NewcomerTasks.json \
            --create-only \
            --json \
            --summary "Growth features configuration boilerplate ([[phab:$PHAB]])" \
            link-recommendation \
            '{ "type": "link-recommendation", "group": "easy" }'
    jq "select(.wiki==\"$WIKI\" and .probability > 0.25) | .section" wiki_sections.jsonl \
        | jq --slurp --compact-output "unique" \
        | mwscript extensions/GrowthExperiments/maintenance/changeWikiConfig.php $WIKI \
            --page MediaWiki:NewcomerTasks.json \
            --json \
            --summary "machine-generated configuration for excluding sections from link recommendations ([[phab:$PHAB]]), feel free to improve" \
            link-recommendation.excludedSections \
            "`cat`"
    echo "$ORIGIN/wiki/MediaWiki:NewcomerTasks.json"
    echo "$ORIGIN/w/index.php?title=MediaWiki:NewcomerTasks.json&diff=next"
    echo "Press <Enter> to continue"
    read # give time for manual verification
done

Note that the script didn't populate excludedSections for towiki and tywiki because these were not present in the wiki_sections.jsonl, see T345562. Also vowiki didn't populate excluded sections because the probability for the ones in wiki_sections.jsonl were too low.

Checked selected wikis from the list - all works as expected; leaving in the Test in Production column to monitor it during this week.
