# Conversational Labeling

The conversational labeling project is similar to span labeling project, allowing you to apply span labels and draw arrows as usual. See [span labeling](/data-studio-projects/lets-get-labeling/span-based.md) for more details. Unlike span labeling, conversational labeling focuses more on conversation data and includes message-level labeling.

### Apply message labels

To apply a message label, click on the add (**+**) button at the top right of a message.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.datasaur.ai/data-studio-projects/lets-get-labeling/conversational-labeling.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
