Amazon Comprehend now supports real time Custom Classification. You can use the real time Custom Classification to understand, label and route information based on your own business rules in real time. For example, you can instantly categorize the content of support requests and route them to the proper support team. Or you can automatically moderate website comments as they’re flowing in. Prior to this launch, customers used Custom Classification with their business-specific labels to categorize documents asynchronously. Now, customers can choose real time or asynchronous Custom Classification depending on their use case.
