I am running multiple evaluation tests on my new work regarding unsupervised AKE, Can you please list any social media or news datasets that are useful for evaluating AKE systems?

I need the dataset to be annotated with keyphrases by experts, and each annotation is based on controlled vocabulary.

I already have multiple scientific corpora like SemVal-2010, PubMed, and Inspec, but looking for datasets in other domains as my AKE system is domain-agnostic.

Thank you in advance.
