Yes. We use the Natural Language Understanding service at www.bustle.com for doing categorization of content. It maps decently to IAB categories: https://www.iab.com/guidelines/iab-quality-assurance-guideli...
Thanks for giving an actual example. Looks like it's a tiered model, first classing into broad categories and then the specific labels? What was integration like: fairly straightforward or was there a long setup/tuning process?
Very straightforward. We send text, they send back categories. We then map those to IAB categories in our own code
