PREDICTIVE DATA SOURCE SELECTION FOR REQUEST HANDLING SYSTEMS

A method includes: at an aggregator, storing historical data representing: (i) a plurality of previous search requests received at the aggregator, and (ii) for each previous search request, an outcome indicator defining whether a supplier subsystem generated previous search results meeting a relevance threshold in response to the previous search request; receiving, at the aggregator from a client subsystem, a search request containing a set of client search parameters; in response to receiving the search request, determining, based on the search request and the historical data, a likelihood of the supplier subsystem generating search results meeting the relevance threshold; and selecting, according to the likelihood, a routing action for the search request, relative to the supplier subsystem.
