  • Publication number: 20240069860
    Abstract: A voice-controlled question answering system that is capable of answering questions using both a knowledge base and a search engine. The knowledge base is used to answer questions when answers to those questions are contained in the knowledge base. If an answer using the knowledge base is unavailable, and if the question is suitable for answering using an unstructured search approach, the system may obtain an answer using a search engine. The search engine results may be processed to obtain an answer to the question suitable for output using a voice user interface.

  • Publication number: 20220417036
    Abstract: Systems and methods are described for rotating keys in a trust store to be used by a group of peer devices for secure communications between the peers in the group. In some examples, a service, such as an identify authority service, may make a determination that a set of peers that individually trust at least one public key from a group of public keys satisfies a set of conditions. As a result of the determination, the service may update the plurality of public keys by at least removing at least one public key from the group of public keys and indicate the updated plurality of public keys to at least one of the peers in the group. The service may remove the at least one public key from the group upon determining that less than a threshold number of peers in the group use the at least one public key.
