1. A method, in a data processing system comprising a processor and a memory, for evaluating an evidential statement in a corpus of evidence, comprising:

  • configuring the data processing system to execute a corpora management engine;

    receiving, by the corpora management engine executing on the data processing system, an evidential statement, from a corpus of electronically stored documents, for determining a level of confidence in a hypothetical ontological link of an ontology data structure;

    identifying, by the corpora management engine executing on the data processing system, a source of the evidential statement based on a source profile directory data structure associated with the corpus of electronically stored documents;

    determining, by the corpora management engine executing on the data processing system, a grading of the source of the evidential statement based on a source grading measurement value indicative of a degree of reliability and credibility of the source calculated based on information in the source profile directory data structure corresponding to the source;

    generating, by the corpora management engine executing on the data processing system, an indication of trustworthiness of the evidential statement based on the source grading measurement value; and

    managing, by the corpora management engine executing on the data processing system, a corpus of evidence data based on the grading of the source of the evidential statement, wherein managing the corpus comprises comparing the source grading measurement value to one or more predetermined threshold values and performing a corpus management operation based on results of the comparison, and wherein, in response to the comparison indicating that the source grading measurement is below a first threshold, removing evidence data associated with the source from the corpus.
