1. A computer-implemented method for controlling processing of a data stream employing utilization of uncertainty dependency relationships, the computer-implemented method comprising: receiving elements of data of a hierarchy to form received data, wherein each element has associated dependency information; creating a set of data streams; receiving elements, associated with a specific terminal node, from the received data into a respective data stream associated with the specific terminal node; processing data streams in the set of data streams individually using the associated dependency information; determining whether processing of a stream in the set of data streams is successful; and responsive to a determination that processing each stream in the set of data streams is successful, terminating controlling processing.
