Deterministic multi-length sliding window protocol for contiguous string entity

A system for extracting verifiable entities from a user-utterance received on an automated calling service, the system comprising:

• a receiver configured to receive a user-utterance;
• a processor;
• a non-transitory computer-readable media comprising computer-executable instructions which, when executed by the processor:
• canonicalize the user-utterance into a plurality of tokens;
• determine the number of tokens of the user-utterance;
• generate, using a sliding-window protocol, a comprehensive number of n-gram sequences from the user-utterance, the number of n-gram sequences equal to the number of determined tokens, each n-gram sequence including a window-size equal to a value of n in the n-gram sequence;
• retrieve a first n-gram from each n-gram sequence;
• process, in parallel, a plurality of threads of execution, one thread of execution from the plurality of threads of execution for each n-gram sequence, the process of the plurality of threads of execution comprises a series of actions on the comprehensive n-gram sequences to:
• determine the first n-gram or a subsequent n-gram to be verifiable, said verifiable to verify the n-gram as a noun;
• in the event that the first n-gram or the subsequent n-gram is not determined to be verifiable, the processor is configured to retrieve the subsequent n-gram from each n-gram sequence and repeat the series of actions for the subsequent n-gram;
• search, in a database of stored entity-verifiers, for an entity-verifier associated with the verified n-gram;
• in the event that an entity-verifier associated with the verified n-gram is not found in the database, the processor is configured to retrieve the subsequent n-gram from each n-gram sequence and repeat the series of actions on the subsequent n-gram;
• invoke the entity-verifier on the verified n-gram to determine the n-gram to be a valid entity;
• in the event that the n-gram is not determined to be a valid entity, the processor is configured to retrieve the subsequent n-gram from each n-gram sequence and repeat the series of actions on the subsequent n-gram;
• and
• transmit the valid entity to an entity assembler.
