Hi Rapidminer users,

I tried to use facebook extension to extract data from facebook. I notice there is 4 operators in the extension. However there is no example in there. i try it all and only 2 of it success, which is Find Page Content and Find Reactions. Can someone give an example on how to use these operators?

Hi @yansheng_ho

I think the extension is outdated, because Facebook did several changes in their own API (and they continue to change it periodically). Their data privacy policies have also changed, so that you need to get permission or be friends with the user to access the data.

Your best bet is to use the Facebook API directly, either with the Enrich Data by Web Service operator or using some external library like Python's Requests.

Kind regards,

Sebastian
