As described herein, a system, method, and computer program are provided for context-based data-driven classification. Input to be processed using a classifier is identified. Data is obtained from one or more third party data sources, based on the input to be processed. The input is processed, using the classifier, to generate output that includes at least one classification for the input. Both the data from the one or more third party data sources and the output of the classifier are processed to determine a final classification for the input.
