1. A computer system for modifying a set of annotations that include metadata describing properties of associated text fragments within an annotated text corpus, comprising:

  • at least one processor circuit having;

    an extracting engine configured to;

    receive a query specifying parameters for annotations from the set of the annotations;

    extract, from the set of annotations and by the query, a first entity subset of annotations, a second entity subset of annotations, and a relations subset of annotations between the first entity subset of annotations and the second entity subset of annotations; and

    extract, from the annotated text corpus, contextual information relative to the extracted annotations, wherein each annotation in the first and second entity subset of annotations serves as an anchor for each respective relations subset annotation and each piece of contextual information;

    a processing engine configured to;

    generate a user interface having display frames populated by frame elements that include the entity subsets of annotations, the relations subset of annotations, and the contextual information; and

    receive, responsive to selections of the frame elements, input specifying modifications to the annotations;

    an updating engine configured to;

    modify, based on the input specifying modifications to the annotations, the set of annotations in the annotated text corpus;

    and the processing engine further configured to;

    receive additional input specifying a change to the particular annotation label; and

    receive additional input specifying a subset of the plurality of annotations; and

    the updating engine further configured to;

    modify, based on the additional input, the particular annotation label for each of the annotations in the subset of the plurality of annotations having the shared particular annotation label.
