Collecting Comments from an FB Post using RapidMiner

Hello RapidMiner Community,

I wonder if there's a way for us to collect comments from an FB post using RapidMiner? Hope someone can help me with this.

Thanks,
Wine

Hi Wine,

you can just use the facebook graph API together with the GET (REST) and the JSON to Data operator from the Web Extension.

The url would be something like this

https://graph.facebook.com/v13.0/%{comment-id}/comments?access_token=%{access-token}&debug=all&fields=id%2Cmessage&format=json&method=get&pretty=0&suppress_http_code=1&transport=cors

You can use the Set Macros operator to set the comment-id and the access-token.

See https://developers.facebook.com/docs/graph-api/reference/v13.0/comment for more details.

You might need to verify yourself to facebook to use this api.

Hi Wine,

great to hear that you got it to work.

Here is at least a super complicated way to do it that i found in another thread https://community.rapidminer.com/discussion/comment/23738/

Hi Wine,

you can just use the facebook graph API together with the GET (REST) and the JSON to Data operator from the Web Extension.

The url would be something like this

https://graph.facebook.com/v13.0/%{comment-id}/comments?access_token=%{access-token}&debug=all&fields=id%2Cmessage&format=json&method=get&pretty=0&suppress_http_code=1&transport=cors

Wine

Thanks so much, Jonas. This is immensely helpful. I'm trying this out.

Hello Jonas,

Thanks for this. I followed your instructions. I was able to get both comment ID and access token from FB and placed it in the "set macros" operator:

Then I placed the url you sent in the get(rest) operator:

https://graph.facebook.com/v13.0/%{comment-id}/comments?access_token=%{access-token}&debug=all&fields=id%2Cmessage&format=json&method=get&pretty=0&suppress_http_code=1&transport=cors

Image: https://us.v-cdn.net/6030995/uploads/editor/qk/xqhvby1z51es.png

However, I get an error when running:

Image: https://us.v-cdn.net/6030995/uploads/editor/gw/79h3u5ecm1jj.png

I get this despite putting the macros in the set macros. Not sure what I did wrong. Hope you can enlighten me with this one. Thanks so much for replying and helping.

Warm regards from the Philippines,
Wine

Wine

Wohoo! I was able to make it work :-) This is a really big help. My next issue it to fix the table. I wonder how I can fix this into columns. Thanks so much, Jonas! :-)

Super big thanks! Jonas 😄 I’ll employ that too for the table. What I initially did was to fix the output using excel. Many many thanks.
