Moderator Tools/Automoderator/Testando
Para ajudar as comunidades a testar e avaliar a precisão do Automoderator, estamos disponibilizando uma planilha de teste com dados sobre edições anteriores e se o Automoderator as teria revertido ou não.
As decisões do Automoderator resultam de uma combinação de pontuação do modelo de aprendizado de máquina e configurações internas. Embora o modelo melhore com o tempo por meio de retreinamento, também estamos buscando aprimorar sua precisão ao definir algumas regras internas adicionais. Por exemplo, observamos que o Automoderator ocasionalmente identifica erroneamente usuários revertendo suas próprias edições como vandalismo. Para melhorar, estamos buscando exemplos semelhantes e agradecemos sua assistência em identificá-los.
Observe que este teste não reflete necessariamente a forma final do Automoderator - usaremos os resultados deste teste para aprimorá-lo!

About Automoderator
Automoderator’s model is trained exclusively on Wikipedia’s main namespace pages, limiting its dataset to edits made to Wikipedia articles. Further details can be found below:
Internal configuration
In the current version of the spreadsheet, in addition to considering the model score, Automoderator does not take actions on:
- Edits made by administrators
- Edits made by bots
- Edits which are self-reverts
- New page creations
The datasets contain edits which meet these criteria, but Automoderator should never say it will revert them. This behaviour and the list above will be updated as testing progresses if we add new exclusions or configurations.
Caution levels
In this test Automoderator has five 'caution' levels, defining the revert likelihood threshold above which Automoderator will revert an edit.
- At high caution, Automoderator will need to be very confident to revert an edit. This means it will revert fewer edits overall, but do so with a higher accuracy.
- At low caution, Automoderator will be less strict about its confidence level. It will revert more edits, but be less accurate.
The caution levels in this test have been set by the Moderator Tools team based on our observations of the models accuracy and coverage. To illustrate the number of reverts expected at different caution levels see below:
Daily edits | Daily edit reverts | Average daily reverts by Automoderator | |||||
---|---|---|---|---|---|---|---|
Very cautious
>0,99 |
Cautious
>0,985 |
Somewhat cautious
>0,98 |
Low caution
>0,975 |
Not cautious
>0,97 | |||

Score an individual edit
We have created a simple user script to retrieve a Revert Risk score for an individual edit.
Simply import User:JSherman (WMF)/revertrisk.js into your commons.js with mw.loader.load( 'https://en.wikipedia.org/wiki/User:JSherman_(WMF)/revertrisk.js?action=raw&ctype=text/javascript' );
.
You should then find a 'Get revert risk score' in the Tools menu in your sidebar. Note that this will only display the model score, and does not take into account Automoderator's internal configurations as detailed above. See the table above for the scores above which we are investigating Automoderator's false positive rate.
Initial results
Quantitative
22 testing spreadsheets were shared back with us, totalling more than 600 reviewed edits from 6 Wikimedia projects. We have aggregated the data to analyse how accurate Automoderator would be at different caution levels:
Not cautious (0.97) | Low caution (0.975) | Somewhat cautious (0.98) | Cautious (0.985) | Very cautious (0.99) |
---|---|---|---|---|
75% | 82% | 93% | 95% | 100% |
In our Moderator Tools/Automoderator/Measurement plan we said that we wanted the most permissive option Automoderator could be set at to have an accuracy of 90%. The ‘Not cautious’ and ‘Low caution’ levels are clearly below this, which isn’t surprising as we didn’t have clear data from which to select these initial thresholds. We will be removing the ‘Not cautious’ threshold, as a 25% error rate is clearly too low for any communities. We will retain ‘Low caution’ for now, and monitor how its accuracy changes as model and Automoderator improvements occur leading up to deployment. We want to err on the side of Automoderator not removing bad edits, so this is a priority for us to continue reviewing.
When we have real world accuracy data from Automoderator's pilot deployment we can investigate this further and consider changing the available thresholds further.
Qualitative
On the testing talk page and elsewhere we also received qualitative thoughts from patrollers.
Overall feedback about Automoderator’s accuracy was positive, with editors feeling comfortable at various thresholds, including some on the lower end of the scale.
Some editors raised concerns about the volume of edits Automoderator would actually revert being relatively low. This is something that we’ll continue to discuss with communities. From our analysis (T341857#9054727) we found that Automoderator would be operating at a somewhat similar capacity to existing anti-vandalism bots developed by volunteers, but we’ll continue to investigate ways to increase Automoderator’s coverage while minimising false positives.
Next steps
Based on the results above, we feel confident in the model’s accuracy and plan to continue our work on Automoderator. We will now start technical work on the software, while exploring designs for the user interface. We expect that the next update we share will contain configuration wireframes for feedback.
In the meantime please feel free to continue testing Automoderator via the process above - more data and insights will continue to have a positive impact on this project.
