1. A computer-implemented method of identifying aspects of constituents in a textual input that are useful in determining a meaning of a textual input, the aspects comprising relation or case information, the method comprising:
- (a) selecting a first aspect;
(b) identifying constituents in a textual corpus corresponding to the selected aspect; and
(c) obtaining an indication of the usefulness of the identified constituents in determining the meaning of the textual input, wherein selecting a first aspect (c) comprises selecting a first relation;
(d) repeating steps (a)–
(c) for each desired relation; and
(e) ranking the desired relations in a relation hierarchy based on the indication of usefulness for each desired relation.

Abstract
A system is utilized for determining a relationship between first and second textual inputs. The system identifies constituents in the first textual input, having predetermined characteristics indicative of usefulness in determining the relationship. The relationship is then determined based on the constituents identified. The constituents can be eliminated from the first textual input, weighted in the first textual input, or simply annotated in one of a variety of ways.

4. A computer-implemented method of identifying aspects of constituents in a textual input that are useful in determining a meaning of a textual input, the aspects comprising relation or case information, the method comprising:
-
(a) selecting a first aspect; (b) identifying constituents in a textual corpus corresponding to the selected aspect; and (c) obtaining an indication of the usefulness of the identified constituents in determining the meaning of the textual input, wherein the selected aspect comprises case information corresponding to constituents in the textual input and wherein identifying constituents comprises identifying constituents in the textual input corresponding to the first case information; and (d) determining whether to identify the first case information as being useful in determining the meaning of the first textual input based on the indication of usefulness. - View Dependent Claims (5, 6, 7, 8)
