AzureCognitive extends the class framework provided by AzureRMR to support Cognitive Services. You can create, retrieve, update, and delete cognitive service resources by calling the corresponding methods for a resource group.
az <- AzureRMR::get_azure_login() sub <- az$get_subscription("sub_id") rg <- sub$get_resource_group("rgname") # create a new Computer Vision service rg$create_cognitive_service("myvisionservice", service_type="ComputerVision", service_tier="S1") # retrieve it cogsvc <- rg$get_cognitive_service("myvisionservice") # list subscription keys cogsvc$list_keys()
AzureCognitive implements basic functionality for communicating with a cognitive service endpoint. While it can be called by the end-user, it is meant to provide a foundation for other packages that will support specific services, like Computer Vision, LUIS (language understanding), etc.
# getting the endpoint from the resource object endp <- cogsvc$get_endpoint() # or standalone (must provide subscription key or other means of authentication) endp <- cognitive_endpoint("https://myvisionservice.cognitiveservices.azure.com/", service_type="ComputerVision", key="key") # analyze an image img_link <- "https://news.microsoft.com/uploads/2014/09/billg1_print.jpg" call_cognitive_endpoint(endp, operation="analyze", body=list(url=img_link), options=list(details="celebrities"), http_verb="POST")
