The Keyword Labelling Service is a core feature of the Data Intelligence platform and a also a stand-alone service. Based on the parameters/details of a transaction, it may assign one or many labels, that are used in our own solution to filter transactions upfront to analysis and calculation steps. Using this service directly allows customers, to implement their own analysis tailored to their specific use case.
