## 🏷️ Tagging Validation

**What is Tagging Validation?**

- The Tagging Validation stage begins once you have been granted access to your project which contains a sample of your data tagged according to your new theme structure.
- This exercise is your opportunity to make any **_significant changes_** to your tagging, before we deploy your model.

**What is Tagging Validation best practice?**

- Please go through each of the categories/themes and ensure you are happy with how the theme tags have been applied.
- The sample is large, so you **_do_** **_not need to check every single comment_**.
- Provide all your feedback on the document provided - your Implementation Manager will cover this during your Tagging Review session.
- To ensure alignment, we recommend that **_only_** the stakeholders who participated in the Theme Structure Review also participate in the Tagging Review.

**What type of feedback can I give during the validation stage?**

- **Incorrect sentiment** - you feel a theme tag has been correctly applied, but the sentiment is incorrect.
- **Remove theme tag** - you feel a theme tag has been unnecessarily or incorrectly applied to a comment.
- **Add theme tag** - you feel a theme tag is missing from a comment and needs to be added.

**FAQs**

**_What is model deployment?_**

- **Model deployment** is when we activate the algorithm trained on the comment sample you reviewed. From this point forward, the model will process the remaining backdate and all new, incoming data.
- This is why the validation exercise is your opportunity to make requests significant changes to your tagging.
- Once this validation exercise is complete, your model will be deployed. 🎉

**_Is there a limit to the number of theme tags a single comment can have?_**

- No, the number of theme tags is not limited and will be based on the comment context and content.

**_Will I be able to change theme tagging after the model is deployed?_**

- Yes, only full Admins will be able to change the tagging on the individual comment level. This includes adding themes, removing themes and amending sentiment.
- We recommend doing this only on an ad-hoc basis.

**_What if I want to change theme tagging or sentiment for numerous comments at once after model deployment?_**

- If you feel that the theme tagging/and or sentiment for a larger segment of comments needs amending, this would require model retraining. Reach out to your CSM who will liaise with the Machine Learning team to conduct a review.
