Discrepancy curator for documents in a corpus of a cognitive computing system

A computer program product comprising:

• a computer-readable memory which is not a propagating signal, per se;
• and
• program instructions encoded by the computer-readable memory for causing a processor, when executed, to perform steps comprising:
• producing, on a user interface device, a parse tree illustration that includes a cluster model and one or more confidence ratings, wherein the cluster model contains one or more previously-detected discrepancies between at least a first portion of a first electronic document and at least a second electronic document in a curated information corpus, wherein the first portion and the second document comprise natural language text strings from a plurality of natural language text documents related to the curated information corpus, and wherein the one or more confidence ratings are previously-assigned to the natural language text strings from the plurality of natural language text documents;
• responsive to receipt, from a user via the user interface device, of a user selection of at least one of the one or more previously-detected discrepancies in the cluster model, returning, to the user via the user interface device, a drill down dialog including one or more drill-down details, wherein the drill-down details include at least two or more conflicting natural language text strings, the one or more confidence ratings, a user-selectable option to reference the parse tree illustration, and at least one user-selectable administrative action option for handling the at least two or more conflicting natural language text strings;
• and
• responsive to receipt, from the user via the user interface device, of a user selection of the at least one user-selectable administrative action option, performing, by the processor, the selected administrative action option to further curate the information corpus and recording, by the processor, the selected administrative action option in a tracking list.
