I need some twitter data set for educational and research purposes, asap. Kindly give me advise regarding this.
The best way to do this is to consume from our Streaming API, using the statuses/filter method and the track parameter. For documentation, see https://dev.twitter.com/docs/streaming-api/methods#track . This is a real-time resource, so it can’t be used to find Tweets over a given date range. If you anticipate needing to gather all Tweets with a certain keyword over a certain time period, we recommend establishing this connection well in advance.
