Using the Twitter Connector

The Twitter Connector allows you to easily access Twitter data directly from RapidMiner Studio. The connector can search for phrases, tweets, or user profile information. This document will walk you through how to:

• Connect to your Twitter account
• Search for tweets containing a phrase
• Get tweets from a user
• Get account details of a Twitter user
• Get a list of friends or followers

The Twitter Connector uses an authentication mechanism calledOAuth 2.0. Instead of giving RapidMiner your username and password, you generate an access token that can be used by RapidMiner Studio to connect to your Twitter account. This token cannot be used by any other applications and helps keep your Twitter credentials secure.
