OpenAlex’s SDG tags are now right 7 times in 10, up from 3

OpenAlex has a new classifier for the UN Sustainable Development Goals, and it’s much more accurate than the old one. On 2,000 works drawn at random from OpenAlex, its SDG tags are right 68% of the time; the old model’s were right 29% of the time. It replaces the old tags on every work today.
