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.

23. A method of determining a relationship between first and second textual inputs, the method comprising:
-
analyzing the first textual input to obtain relations of constituents thereof;
determining a relative importance of the constituents in determining the relationship between the first and second textual inputs based on the relations obtained; and
determining the relationship between the first and second textual inputs based on the constituents and the relative importance of the constituents. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32)

34. A computer readable medium storing a data structure used in determining a relationship between first and second textual inputs, the data structure comprising:
-
a plurality of pre-computed aspects of at least one of the first and second textual inputs, the pre-computed aspects being useful in determining the relationship between the first and second textual inputs;
wherein the plurality of pre-computed aspects includes a linguistic analysis of at least a portion of the first and second textual inputs. - View Dependent Claims (35)

36. A method of determining a relationship between first and second textual inputs, the method comprising:
-
obtaining a hierarchy of relations;
obtaining a hierarchy threshold based on a usefulness of the relations in the hierarchy in determining the relationship between the first and second textual inputs;
identifying constituents in the first textual input that have the relations in the hierarchy;
determining a usefulness of the identified constituents by locating the identified constituents in the hierarchy; and
determining the relationship between the first and second textual inputs based on identified constituents having associated relations above the hierarchy threshold.
