[Air-L] Facebook key word sampling and analysis

Hello all, I was wondering if any of you might be able to share examples of studies that mechanically collected data from Facebook based on key words. I am specifically interested in big data collection and analysis that does not focus on a set of specific pages/groups but rather focused on key words that led to sampling from the entirety of accessible/public/open posts on FB in a specific timeline. Many thanks, and have a lovely weekend, Aya -- *Aya Yadlin-Segal, **Ph.D.* Postdoctoral researcher Department of Communication University of Haifa
