Note: Unfortunately, the Sifter service and website has been decommissioned as of September 30, 2018. Thanks to our 6,970 users who created 16,128 free estimates from the complete, undeleted history of Twitter between 1/14/2014 and 9/29/2018. Please contact Twitter for approval of future academic or commercial use cases. If you can get an approved use case from Twitter, we can still help you work with the data inside DiscoverText. @DiscoverText remains open and is still the top-ranked text analysis platform on the Internet. All paid jobs prior to the decommissioning will still be honored. ========================================================================== This page has information about using Sifter to license data from the complete, undeleted history of Twitter. Many first time Sifter users assume they are buying direct access to the data. In fact, Sifter is a tool that allows you to license the data for analysis on DiscoverText in compliance with the Twitter Terms of Service. After a Sifter user accepts an estimate, we send a PayPal invoice so you can complete the license transaction using a credit card. Once the transaction is complete, we start the download from Twitter to your DiscoverText account.
- What time zone is used when searching Twitter tweets within a date range?
- When can I expect to receive Sifter data paid for via PayPal?
- Why am I unable to find very old (historical) Twitter tweets?
- Why are there so few results when using Twitter's (Gnip PowerTrack) geo (geographic) rules?
- Why did I receive lots of Sifter errors when requesting an estimate?
- Why does a Gnip PowerTrack Twitter estimate with a shorter time duration have more tweets and cost more than for a longer duration?
- Why is my Sifter data broken up into 50,000 item archives? Can I regroup them altogether?
- Why is the data for my estimates split into several archives?
- Why is the number of data items (e.g., tweets) different from the Sifter estimate?
