Often times a customer may way to reorder something they bought in the past. Since all previous orders are data points for our service, we can look up past information so we know what the customer is referencing.
In this conversation the customer notes red scarf and last time. Those two point lead our system to retrieve an item called “red scarf” from the last order she placed with that title. This type of scenario is important for size or brand variations.
The response reminds the user when the order was placed for further clarification and then asks how many should be added to the order.
