Cognitive systematic review (csr) for smarter cognitive solutions

A system for determining a veracity of a reported event, comprising:

• a memory medium comprising instructions;
• a bus coupled to the memory medium;
• and
• a processor coupled to the bus that when executing the instructions causes the system to:
• retrieve, from a selected use case, a set of predictor variables, each predicator variable of the set of predictor variables being a condition that indicates the veracity of the reported event;
• generate, using a cognitive system, a set of hidden predictor variables from a set of unstructured documents related to the reported event using a hidden Markov model that is based on the predictor variables;
• generate a set of updated predictor variables by combining the set of predictor variables and the hidden predictor variables;
• generate a set of updated predictor variables by combining the set of predictor variables and the hidden predictor variables;
• and
• return, by the cognitive system, a determination of the veracity of the reported event based on the updated predictor variables.

A computer program product for determining a veracity of a reported event, the computer program product comprising a computer readable storage media, and program instructions stored on the computer readable storage media, that cause at least one computer device to:

• retrieve, from a selected use case, a set of predictor variables, each predicator variable of the set of predictor variables being a condition that indicates the veracity of the reported event;
• generate, using a cognitive system, a set of hidden predictor variables from a set of unstructured documents related to the reported event using a hidden Markov model that is based on the predictor variables;
• generate a set of updated predictor variables by combining the set of predictor variables and the hidden predictor variables;
• and
• return, by the cognitive system, a determination of the veracity of the reported event based on the updated predictor variables.
