Abstract: Systems and methods for providing preauthorization requirements are described. An illustrative method may include receiving an input comprising service information and service provider information, retrieving stored preauthorization information from the database based on the service and the service provider, capturing, via a web crawler, raw updated preauthorization information from the networked location, structuring the raw updated preauthorization information using a generative transformer to generate structured updated preauthorization information, detecting changes between the stored preauthorization information and the structured updated preauthorization information, and, in response to detecting changes, updating the stored preauthorization information based on the structured updated preauthorization information.

Abstract: Techniques for resource sharing between cloud-hosted virtual networks are described. A first network address of a first virtual network is associated with a resource connected to a second virtual network, the first and second virtual networks within a cloud provider network. A service of the cloud provider network receives a message destined for the first network address. The service translates the first network address to a second network address of the resource in the second virtual private network. The service sends the message to the resource at the second network address in the second virtual network.

Abstract: Systems and methods for automatically approving prior authorization requests for an episode of service are described. An illustrative system may be used by insurance providers, clients, and third parties to request prior authorizations for episodes of service with real-time approvals if a requested service meets authorization criteria. Throughout each step of the authorization process, transactional information is logged and securely sent to all key parties using the blockchain.

Abstract: Systems and methods for automatically answering questions based on a biomedical document are presented herein. The system may include a question-answering machine learning model. The question-answering machine learning model may be enhanced by segmenting the document. The system may include a topic clustering machine learning model for segmenting the document. Through segmentation, the resulting system may provide a lower error rate at a lower computational cost when compared to traditional question-answering machine learning models.

Abstract: Techniques for defining and enforcing a set of rules that regulate network activity on a virtual network within a provider are described. An activity rule that regulates network activity on a virtual network within a provider network is received, the virtual network shared by a first customer of the provider network to allow other customers of the provider network to connect resource instances to the virtual network. Network activity data is received from a monitoring agent within the provider network, the network activity data relating to an activity of a first resource instance of a first other customer on the virtual network. The activity of the first resource instance is determined to violate the activity rule. The first resource instance is isolated from at least a portion of the virtual network.

Abstract: A subnet of a logically isolated network within a provider network may be shared between client accounts of the provider network. A request to share a subnet of a logically isolated network created for one client account with another client account may be received. A link between an account object for the other client account and a shared subnet object for the subnet may be stored. When a request to host a resource with the subnet is received, an evaluation of the graph may indicate whether the request to place the host is permitted. If permitted, the resource for the other client host may be hosted within the subnet.
