[Air-L] Facebook scraper for qualitative analysis

Hi to all, I've been trying to import data form a public Facebook group as dataset, mainly for qualitative analysis. The group includes substantial amounts of data with thousands of users. I would need to extract data (posts and comments) for at least a two months period. I was previously using a NVivo extension (NCapture) to do so, but Facebook recently changes its API, which implies restrictions for dataset import. Tools such as Netvizz don't seem to work at the moment as well. I was wondering if you knew about other ways or ressources to make such a gathering possible. Best, Alexandra
