The #growth-team plans to release a new Add Link related feature soon: {T385343}. This would be targeted to 6 pilot wikis (see the other task). The Add Link model for those wikis was trained a fairly long time ago:
| **Wiki** | **Trained on** |
| eswiki | 2021-06-23 |
| frwiki | 2021-03-01 |
| arzwiki | 2022-05-24 |
| ~~ruwiki~~ | 2021-06-23 |
| ptwiki | 2021-03-31 |
| fawiki | 2021-06-23 |
| idwiki | 2022-07-18 |
For all wikis, the model is over 2.5 years old (while most wikis have nearly a 4 year old model). This is not great, as the model is based on the article content when it was trained. In addition to that, it is also based on article existence when the model was trained (in other words, we are never suggesting a link to an article that didn't exist ~four years ago). Since articles are created all the time, and the norms at wikis change from time to time, we should be using reasonably recent models, to provide the best quality recommendations possible.
Since we are doing an Add Link experiment, it makes sense to me to retrain the models, and see if there is any difference in the recommendation quality. That would allow us to decide whether we want to schedule retraining //all// Add Link models (for all wikis).
