UTILIZATION OF UNCERTAINTY DEPENDENCY RELATIONSHIPS BETWEEN ITEMS IN A DATA STREAM

A computer-implemented method, computer program product and computer system for controlling processing of a data stream employing utilization of uncertainty dependency relationships, by 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 of each stream in the set of data streams is successful the computer-implemented process, terminating controlling processing.
