1. A system for verifying a statement, the system comprising: a first computing system including at least one memory device and at least one processor connected to the memory device, wherein the first computing system is configured to: receive a statement; decompose the received statement into one or more sets of question and answer pairs; determine a confidence value of each answer in the one or more question and answer pair sets; and combine the determined confidence values, the combined confidence values representing a probability that the received statement is evaluated as correct, wherein in order to combine the determined confidence values, the first computing system is further configured to: fit the determined confidence values to training data in order to obtain weights associated with the determined confidence values; obtain, based on the fitting, weights associated with the determined confidence values; and obtain a mathematical model, Z=w 1 xx 1 +w 2 xx 2 +.. . +w n xx n , f(Z)=1/(1+e^(-Z)), where w 1 , w 2 ,. .. , w n , are the obtained weights, x 1 x 2. .. , x n are the determined confidence values, and f(Z) represents a probability of correctness of a statement associated with the determined confidence values.
