Re-activating a suspended source is the same operation: the source will have a "Enable Source" button in the same place, and clicking on it and confirming will perform the following:

In other cases, particularly as your activities move from data investigation to data science, it becomes necessary either to apply either more complex algorithms (for example graph theory or social network analysis), or to calculate standard statistics in domain-specific (a very simple example of this would be aggregating sentiment geographically).
TODO screenshots (sentiment + geo -> custom geo)
In order to support these sorts of operations, Infinit.e provides the ability to plug-in analytic modules that can run over any subset of the data (including all of it). The general topic of building plug-in modules and scheduling and running them is beyond the scope of this documentation; this section will provide links to the Infinit.e documentation and describe the aspects most relevant to Datasift.
In particular, we have provided 3 sample jobs that illustrate a few different types of analytic and demonstrate how to access the document objects, and interpret the results (in practice the Infinit.e-specific bits like this are very easy, the difficulty is typically in building the algorithms themselves, as it should be).

Note that the examples below assume that you have an instance into which you have loaded some sources and collected some data, using the techniques described in previous sections. |
Example 1 - Aggregate sentiment by geo
This sample analytic can be seen in the screenshot above. It simply creates a 10 degree x 10 degree grid and aggregates the sentiment associated via geo-tagged entities with those grid squares.
The sequence of the screenshots below shows how to access the example (starting from the manager webapp, eg press the "MANAGER" link in the top right of the main GUI):
