Phonetic patterns for fuzzy matching in natural language processing

A computer usable program product comprising a computer-readable storage device, and program instructions stored on the storage device, the stored program instructions comprising:

• program instructions to extract a token from a Natural Language (NL) input;
• program instructions to compute a phonetic pattern corresponding to the token, the phonetic pattern comprising a sound pattern that represents a part of the token when the token is spoken;
• program instructions to create new data from data of the phonetic pattern, the new data comprising a syllable sequence corresponding to the phonetic pattern;
• program instructions to change a state of a data storage device by storing the new data in a matrix of syllable sequences corresponding to the token;
• program instructions to select, by executing a fuzzy matching algorithm using a processor and a memory, an option that corresponds to the token, wherein the selecting is based on a syllable sequence in the matrix;
• and
• program instructions to modify, to form the phonetic pattern, a stored phonetic pattern corresponding to a second token in a phonetic repository, wherein the second token is comparable to the token by having a greater than a threshold degree of structural similarity with the token.

A computer system comprising a processor, a computer-readable memory, and a computer-readable storage device, and program instructions stored on the storage device for execution by the processor via the memory, the stored program instructions comprising:

• program instructions to extract a token from a Natural Language (NL) input;
