I have unsuccesfully trying to find something that accomplish the following. I wonder if it is possible with the API of Twitter. If not, it would explain why I haven’t been able to find it.
I’m interested in the people that a person is following. I could check every person of that list manually, but it is a huge list. I’d like to filter the people of that list according to a criteria like some words of their descriptions.
Example: Anna is following 1000 users. We want to filter the users who have USA in their profile description. Another filter could be the users who have written fishing in some tweet.
How to do it with Twitter? Is it possible? Is it possible with a 3rd application? Does the Twitter API allow it?
