  • Patent number: 11979494
    Abstract: The disclosed exemplary embodiments include computer-implemented systems, devices, and processes that securely manage and regenerate cryptographic keys using permissioned distributed ledgers. For example, a device may receive, from a first computing system, data indicative of a recordation of a first public key onto a distributed ledger. Based on an occurrence of a regeneration condition, the device may transmit, to a second computing system, a second public key and a first digital signature, and the second computing system may validate the first digital signature, apply a second digital signature to the second public key, and transmit the second public key and the digital signatures to the first computing system. The device also receives, from the first computing system, additional data indicative of a recordation of the second public key onto the distributed ledger, and based on the additional data, the device may invalidate the first private key.

  • Patent number: 11354340
    Abstract: Mechanisms are provided for generating an answer to an input question. The mechanisms process a received input question to identify a temporal categorization of the input question indicating an intended time context for an answer to the input question. The input question does not specify a temporal categorization of the input question. The mechanisms perform analysis of a corpus of information based on the temporal categorization of the input question and temporal categorizations of sources of information in the corpus of information to determine, for each source of information, a degree of correspondence of the temporal categorization of the input question to a temporal categorization of the source of information. An answer to the input question is generated and output based on the degrees of correspondence of the sources of information.

  • Patent number: 11023478
    Abstract: Mechanisms are provided for processing sources of content in a corpus of information associated with a domain. The mechanisms ingest a plurality of sources of content in the corpus of information associated with the domain and determine at least one temporal category for the domain based on identification of frequently occurring references to at least one of temporal terms or time spans specified in the plurality of sources of content in the corpus of information associated with the domain. The mechanisms store the at least one temporal category for the domain in association with the domain and process queries applied to the plurality of sources of content in the corpus of information associated with the domain based on the stored at least one temporal category for the domain.

  • Patent number: 10664763
    Abstract: A method, system and computer-usable medium are disclosed for adjusting fact-based answers provided by a question/answer (QA) system. A user submits a question to the QA system, where it is categorized into a question type. The QA system then processes the question to generate an answer. The QA system then generates an answer adjustment if it is determined that the question type and answer meet a predicted undesirable outcome. The answer adjustment may include a warning, a disclaimer, a recommendation, an alternative fact-based answer, a referral to an assistance service, or any combination thereof.

  • Patent number: 10282396
    Abstract: An object of an in-memory object model created from markup language syntax is identified. The in-memory object model includes an element value that includes both a prefix part and a local value part. A determination is made that the element value, that includes both the prefix part and the local value part, does not have a corresponding data type definition within a schema specification used to define data types within the markup language syntax. A namespace resolver service is invoked using at least the prefix part of the element value. A valid namespace declaration of the prefix part is received from the namespace resolver service. The valid namespace declaration is associated with the prefix part as a namespace definition for the local value part of the element value.

  • Patent number: 10108602
    Abstract: An approach is provided to discover new portmanteau, such as when ingesting documents into a question answering (QA) system. The approach works by analyzing a words included in electronic documents and identifies words as being possible portmanteaus. To analyze a portmanteau found in a document, the approach identifies morphemes that are included in the identified portmanteau and candidate words that correspond to each of the identified morphemes. A meaning for the new portmanteau is then derived from the meanings of the candidate word meanings.

  • Patent number: 10049031
    Abstract: Embodiments of the invention provide for the correlation of violating change sets during regression testing of a computer program. A method of the invention includes annotating a test case with a reference to logical operations of different programmatic objects of a computer program. Thereafter, change sets are applied to the program and the test case is executed by a development environment such as a debugger to a point of failure. It is then determined from the annotations change sets related to the logical operations and different ones of the determined change sets are sequentially replaced and the test case repeatedly re-executed. As such, the ones of the replaced change sets resulting in failure from re-execution of the test case are determined to be violating change sets.

  • Publication number: 20180121606
    Abstract: Mechanisms are provided for evaluating the validity of duplicate medication instances in aggregate patient data. The mechanisms generate aggregate patient data from patient data obtained from computing devices associated with a plurality of different sources of patient data for a patient. The mechanisms analyze the aggregate patient data to identify a duplicate medication instance. The mechanisms determine whether the duplicate medication instance is a valid duplicate medication instance or an invalid duplicate medication instance based on features extracted from the aggregate patient data. The mechanisms, in response to a determination that the duplicate medication instance is an invalid duplicate medication instance, further send a notification to a computing device indicating invalidity of the duplicate medication instance.

  • Publication number: 20180121605
    Abstract: Mechanisms are provided for performing medication reconciliation in patient medical data obtained from a plurality of different sources. The mechanisms receive a plurality of patient medical data for a patient from a plurality of different source computing systems and analyze the patient medical data to identify a medication related content. The mechanisms generate an aggregate medication listing data structure for the patient from the medication related content and correlate medication related data types which are related to a same medication or class of medication. The mechanisms determine whether a modification to the aggregate medication listing data structure is to be performed based on results of the correlation and output a notification to an authorized user indicating a recommended modification to the aggregate medication listing data structure.
