Methods and systems for responding to a natural language query

A method for responding to a natural language query, the method comprising:

• receiving, using control circuitry, a natural language query;
• processing the natural language query using a first natural language understanding model;
• determining, using control circuitry, a confidence level of the understanding of the query, wherein determining the confidence level comprises:
• determining an average confidence score from a plurality of previous natural language queries;
• determining a difference between the confidence level and the average confidence score;
• and
• comparing the difference between the confidence level and the average confidence score to a threshold value;
• in response to the confidence level being below a confidence level threshold, reprocessing the natural language query using a reprocessing module;
• in response to the difference between the confidence level and the average confidence score being above the threshold value, reprocessing the natural language query;
• and
• generating a response to the natural language query based on the processing of the natural language query by the first natural language understanding model and the reprocessing of the natural language query.
