Contextual query rewriting

A system comprising:

• one or more processors;
• and
• one or more computer-readable media storing instructions which, when executed by the one or more processors, cause the system to perform the following operations:
• inputting a first user utterance and a conversation history to a first language model,
• wherein the first language model identifies an ambiguity in the first user utterance and one or more terms in the conversation history to resolve the ambiguity, modifies the first user utterance to include the one or more terms identified to resolve the ambiguity to generate a modified utterance, and outputs the modified utterance;
• providing the modified utterance as input to a second language model, wherein the second language model performs a natural language processing task based on the input modified utterance and outputs a result;
• and
• outputting a response to the first user utterance based on the result.

One or more non-transitory computer-readable media storing instructions which, when executed by one or more processors, cause a system to perform the following operations:

• inputting a first user utterance and a conversation history to a first language model,
• wherein the first language model identifies an ambiguity in the first user utterance and one or more terms in the conversation history to resolve the ambiguity, modifies the first user utterance to include the one or more terms identified to resolve the ambiguity to generate a modified utterance, and outputs the modified utterance;
• providing the modified utterance as input to a second language model, wherein the second language model performs a natural language processing task based on the input modified utterance and outputs a result;
• and
• outputting a response to the first user utterance based on the result.
