Augmented intent and entity extraction using pattern recognition interstitial regular expressions

Abstract:

According to certain embodiments, a system comprises interface circuitry and processing circuitry. The processing circuitry receives an input via the interface circuitry. The input is based on an utterance of a user, and the processing circuitry uses a probabilistic engine to determine one or more candidate intents associated with the utterance. The processing circuitry determines a number of the one or more candidate intents that exceed a threshold. If the number of candidate intents that exceed the threshold does not equal one, the processing circuitry uses a deterministic engine to compare the input to a set of regular expression patterns. If the input matches one of the regular expression patterns, the processing circuitry uses the matching regular expression pattern to determine the intent of the utterance. The interface circuitry communicates the intent of the utterance as an output.
