Observatory on Social Media (OSoMe) Data Access Policy


All agents of the university who wish to access the OSoMe data stored on IUNI's Moe Cluster.

Policy Statement

Indiana University has entered into an agreement with Twitter Inc. to license the 'Twitter Decahose' that provides IU with an ongoing stream of ten percent of all public activity on Twitter. IU has been receiving this data since 2010 (with some interruptions) with the current data exceeding more than seventy billion tweets.

The OSoMe Twitter data is available to all individuals affiliated with Indiana University via the 'Moe's Tavern' interface. To access this interface, users must follow the application process described by this document. Users must use the data in a manner consistent with Twitter's 'Developer Policy and Agreement'.

Reason for Policy

The data contained in the Observatory on Social Media has been licensed by Indiana University from Twitter Inc. and is being used to support a number of research projects across the IU system. Consequently, it is imperative that all users of the data comply with the necessary Policies required by Twitter Inc. to insure continued access to the data for IU researchers.

Additionally, the OSoMe data contains personally identifiable information that could potentially be used to target individuals or groups of Twitter users. Although all the data received by Indiana University is publicly available, the aggregation of the data is not. As a result, users should be aware of how this type of aggregated social media data could be used to negatively affect the users of Twitter. OSoMe users have a responsibility to protect Twitter users as well as Indiana University from abuses of the dataset.
