1. A method for analyzing a search of a source of computer-accessible content, comprising the following steps: accepting, performed at least in part with a configuration of computing hardware and programmable memory, a first search result comprised of a first set of records and a first set of frame instances, wherein each member of the first set of records has a corresponding instance in the first set of frame instances, selecting, performed at least in part with a configuration of computing hardware and programmable memory, role values, from the first set of frame instances, to produce a first set of candidate representative role values, wherein the selecting is performed as part of a determination, from the first set of frame instances, of a first set of representative role values; merging, performed at least in part with a configuration of computing hardware and programmable memory, a first candidate representative role value and a second candidate representative role value, of the first set of candidate representative role values, when it is determined that a first and a second meaning of, respectively, the first and second candidate representative role values, are sufficiently similar, wherein the merging is performed as part of a determination, from the first set of frame instances, of a first set of representative role values; and making accessible, performed at least in part with a configuration of computing hardware and programmable memory, to a user, at least a portion of the first set of representative role values.
