Systems and methods for utilizing user-verified data for training confidence level models. An example method comprises: performing syntactico-semantic analysis of a natural language text to produce a plurality of semantic structures; interpreting, using a set of production rules, the plurality of semantic structures to extract a plurality of information objects representing entities referenced by the natural language text; determining an attribute value for an information object of the plurality of information objects; determining a confidence level associated with the attribute value, by evaluating a confidence function associated with the set of production rules; responsive to determining that the confidence level falls below a threshold confidence value, verifying the attribute value; appending, to a training data set, at least part of the natural language text referencing the information object and the attribute value; and determining, using the training data set, at least one parameter of the confidence function.
