A method, system and a computer program product are provided for verifying ground truth data by iteratively clustering machine-annotated training set examples with validation set examples to identify and display one or more prioritized review candidate training set examples grouped with validation set examples meeting a predetermined misclassification criteria in order to solicit verification or correction feedback from a human subject matter expert for inclusion in an accepted training set.

The computer program product of claim 9, wherein the computer readable program, when executed on the system, causes the system to assign examples from the machine-annotated training set and validation set to one or more clusters by: generating a vector representation for each of example from the machine-annotated training set and validation set using a neural network language model; and applying a rule-based probabilistic algorithm to the vector representations of the machine-annotated training set and validation set examples to identify the one or more clusters using the cluster model. 12. The computer program product of claim 9, where at least one of the predetermined misclassification criteria is that the validation set examples are not annotated by a human annotator. 13. The computer program product of claim 9, where at least one of the predetermined misclassification criteria is that the validation set examples are not annotated by a human annotator or a machine annotator. 14. The computer program product of claim 9, further comprising computer readable program, when executed on the system, causes the system to verify or correct all prioritized review candidates in a cluster as a single group based on verification or correction feedback from the human subject matter expert. 15. The computer program product of claim 9, further comprising computer readable program, when executed on the system, causes the system to verify or correct prioritized review candidates in a cluster one at a time based on verification or correction feedback from the human subject matter expert. 16. An information handling system comprising: one or more processors; a memory coupled to at least one of the processors; and a set of instructions stored in the memory and executed by at least one of the processors to verify ground truth data, wherein the set of instructions are executable to perform actions of: receiving, by the system, a human-curated training set and validation set; performing, by the system, annotation operations on the training set and validation set using an annotator to generate a machine-annotated training set and validation set; assigning, by the system, examples from the machine-annotated training set and validation set to one or more clusters using a cluster model; analyzing, by the system, the one or more clusters to identify one or more training set examples grouped with validation set examples meeting predetermined misclassification criteria; and displaying, by the system, the identified one or more training set examples as prioritized review candidates to solicit verification or correction feedback from a human subject matter expert for inclusion in an accepted training set. 17.
