Abstract:
1. A computer readable medium storing instructions and executed by a computer, causing the computer to perform a method of determining a relationship between a first textual input and a second textual input, the method comprising: obtaining a hierarchy of relations, the relations including at least one of grammatical relations and case; obtaining a hierarchy threshold based on a usefulness of the relations in the hierarchy in determining the relationship between the first textual input and the second textual input; identifying relations of constituents in the first textual input; comparing the relations of the constituents in the first textual input to the relations in the hierarchy to identify constituents in the first textual input, as identified constituents, if they have the relations in the hierarchy; comparing the identified constituents to the hierarchy threshold in the hierarchy to determine whether the identified constituents have relations that are above the hierarchy threshold; calculating the relationship between the first textual input and the second textual input based on the identified constituents that have associated relations above the hierarchy threshold; and outputting an indication of the relationship calculated.
