1. A method performed by at least one computer processor, the method comprising:

  • (a) selecting, by the at least one computer processor, a first question instance including first text and a first region definition designed to identify a first region of a data set likely to contain information that may be used to provide an answer to the question represented by the first text, the first region being aligned with a tagged element in the data set;

    (b) automatically identifying, by the at least one computer processor, before (c) and (e), the first region of the data set, based on the first region definition;

    (c) providing output, by the at least one computer processor, to a user representing the first question instance;

    (d) generating, by the at least one computer processor, an answer to the first question instance based on the first region of the data set before (e);

    (e) receiving, by the at least one computer processor, from the user, feedback before providing to the user output representing the generated answer;

    (f) determining whether the received user feedback indicates the user relied upon the first region of the data set identified in the first region definition;

    (g) determining that a frequency of reliance upon the first region of the data set falls below a predetermined threshold; and

    (h) modifying the first region definition to exclude the first region of the data set from the first region definition.
