Attention Appian Cloud FedRAMP, HIPAA, or PCI-DSS customers:
Use of the Sentiment Score function results in sending data outside of Appian Cloud's FedRAMP, HIPAA, or PCI-DSS in-scope service boundaries. Customers should use caution when using a!sentimentScore() with regulated data, and review for their own compliance requirements.
This function is available only on Appian Cloud and will be enabled on Cloud sites on a rolling basis. You will receive the following error until your site is enabled: This function is currently unavailable. Please contact your system administrator if this problem persists.

Single large text values will typically not provide useful sentiment scores. For best results, split large values into a list of smaller values that are each about the length of a sentence.
You can copy and paste these examples into the Expression Rule Designer to see how this works.
