Is there any dataset available for different categories like music, politics, business etc which can be used to classify input tweets?
The Streaming APIs Overview The Streaming APIs give developers low latency access to Twitter’s global stream of Tweet data. A proper implementation of a streaming client will be pushed messages indicating Tweets and other events have occurred, without any of the overhead associated with polling a REST endpoint.
If your intention is to conduct singular searches, read user profile information, or post Tweets, consider using the REST APIs instead.
