Hey guys,

Thanks a lot for the replies. I might have been a bit vague what I meant by automated:D So, let me clear that up. I plan to simply make a script to recommend categories from an image. There would be users who do check if the category is valid before adding it right now, as the script may not be a 100% reliable (yet). I do understand about bots on Commons and I would definitely not be running any of this without appropriate approval :) So, currently we just recommend categories, for example you can check https://commons.wikimedia.org/wiki/User:AbdealiJKTravis/logs/newimages

Also, Adding Category:Paris to an image is quite fine I believe, because users do have the template {{OverPopCat}} to search for categories which require diffusion. So, essentially if the script is able to add/suggest Category:Paris, there would be users who are interested in Paris specifically who will be able to find that image easily and add a deeper category based on their knowledge. There's also {{check categories}} for every file which helps in such cases.

I do agree I need a reverse geocoding service. I tried nominatim's reverse querying, and was hoping there was an equivalent hosted by wikimedia.

Regards

I agree with Tim's objection to automating this task. Also, the local
community[1] needs to be consulted before running a task. I would
suggest reaching out to them before starting any code.
