## Abstract

Embodiments are disclosed for a query processing system configured to receive user submitted questions and provide answers to the user submitted questions. In an example embodiment a system receives a user query from a user. The system then determines if a response is available that matches an intent of the user query above a threshold confidence level. The systems then prompts the user for permission to enable access to the user query to other users. If permission is granted, the system then enables access to the user query to the user users. Responses to the user query received from one or more of the other users are then output to the user, for example, via a computing device or an appliance. Further, in some embodiments, feedback received from the user regarding output responses can be used to train machine learning models associated with the system.

wherein storing the data corresponding to the particular response in the data repository includes applying a tag to the data corresponding to the particular response, the tag indicative that the particular response is supplied by another user;
receive a second user query from a second user, the second user query similar to the first user query;
determine, using a machine learning model, that the particular response to the first user query matches an intent of the second user query above the threshold level of confidence; and
output the particular response to the second user, the output including the tag indicative that the particular response is supplied by another user.

### Claim 4 (depends on 1)

The system of claim 1, wherein enabling access to the first user query to the plurality of other users includes:
prompting the first user for permission to enable access to the first user query to other users; and
receiving a confirmation indicative of permission to enable access to the first user query to other users.

### Claim 5 (depends on 1)

The system of claim 1, wherein the memory unit includes further instructions, which when executed by the processing unit, cause the system to further:
train the machine learning model based on the feedback received from the first user.

### Claim 6 (depends on 1)

The system of claim 1, wherein storing the data corresponding to the particular response in the data repository includes:
associate the data corresponding to the particular response with data corresponding to the first user query and/or data corresponding to one or more other user queries that are similar to the first user query.

### Claim 7 (depends on 1)

The system of claim 1, wherein enabling access to the first user query includes posting the first user query using any of:
a chatbot;
an online forum; or
a social media platform.

### Claim 8 (depends on 1)

The system of claim 1, wherein the first user query relates to any of:
food;
food preparation; or
operation of a cooking appliance.

### Claim 9 (depends on 1)

The system of claim 1, wherein the message is received from the first user via any of:
a client computing device; or
a cooking appliance.

### Claim 10 (depends on 1)

The system of claim 1, wherein the one or more responses are output to the first user via any of:
a client computing device; or
a cooking appliance.

### Claim 11

A method comprising:
receiving a first user query from a first user;
determining if a response is available that matches an intent of the first user query above a threshold level of confidence;
prompting the first user for permission to enable access to the first user query to a plurality of other users if a response is not available that matches the intent of the first user query above the threshold level of confidence;
enabling access to the first user query to the plurality of other users in response to receiving a confirmation of permission from the first user;
receiving one or more user responses to the first user query from one or more of the plurality of other users;
outputting, to the first user, the one or more user responses to the first user query;
