HR Help Desk Predict Category

Summary

How does the Predict Category feature function?

Content

As I was configuring HRHD, I came across these Profile Options:

SVC_ENABLE_INBOUND_MSG_ATTRIBUTE_PREDICTION

SVC_ENABLE_INBOUND_MSG_SR_CATEGORY_PREDICTION

SVC_INBOUND_MSG_PREDICTION_THRESHOLD_FOR_SR_CATEGORY_ID

I set the Enable options to Y; and the Threshold was set to 0.7, but it does not appear to function. When an email is sent, the category field is not set. I have not found any documentation on this feature or what else needs to be configured to make this work.

Can anyone point me in the right direction?
