Patent Images
1. A method comprising:
- a) receiving, at a computer, a first set of input data comprising a set of website data;
b) defining a grammar, wherein;
i) the grammar comprises a plurality of sub-grammars organized according to a hierarchy comprising a plurality of levels;
ii) the grammar is defined based on data comprising;
1) the first set of input data;
2) a second set of input data; and
3) a third set of input data;
iii) the statements |A B|−
|A∩
B|≠
0 and B C=A C are true where1) A is a first set of levels from the hierarchy in which at least one sub-grammar is defined based on the first set of input data;
2) B is a second set of levels from the hierarchy in which at least one sub-grammar is defined based on the second set of input data; and
3) C is a third set of levels from the hierarchy in which at least one sub-grammar is defined based on the third set of input data; and
c) storing the grammar on a non-transitory computer readable medium.

Abstract
Grammars for interactive voice response systems using natural language understanding can be created using information which is available on websites. These grammars can be created in automated manners and can have various tuning measures applied to obtain optimal results when deployed in a customer contact environment. These grammars can allow a variety of statements to be appropriately handled by the system.
