  • Modeling multiparty conversation dynamics: speaker, response, addressee selection using a novel deep learning approach
    Patent number: 10657962
    Abstract: An information processing system, a computer program product, and methods for modeling multi-party dialog interactions. A method includes learning, directly from data obtained from a multi-party conversational channel, to identify particular multi-party dialog threads as well as participants in one or more conversations. Each participant utterance being converted to a continuous vector representation updated in a model of the multi-party dialog relative to each participant utterance and according to each participant's role selected from the set of: sender, addressee, or observer. The method trains the model to choose a correct addressee and a correct response for each participant utterance, using a joint selection criterion. The method learns directly from the data obtained from the multi-party conversational channel, which dialog turns belong to each particular multi-party dialog thread.

  • Verification of Privacy in a Shared Resource Environment
    Publication number: 20200151351
    Abstract: Embodiments relate to a system, program product, and method for use with a computer platform to support privacy preservation. The platform measures and verifies data privacy provided by a shared resource service provider. An assessment is utilized to support the privacy preservation with respect to a data steward, and associated shared data. It is understood that data associated with a data service has an expected level of privacy. A privacy score directly correlating to a leakage indicator of the service is formed, and an associated data container is populated with inferred entities deemed to at least meet a preferred privacy level. The privacy score effectively certifies the security of the populated data container.
