  • Patent number: 11405696
    Abstract: Various embodiments select advertisements for delivery to at least one mass media streaming device at a given location and time slot. Content and corresponding time and physical location information being posted in an online portal from at least one electronic device are obtained. The content is filtered based on time slot and physical location. A set of typical topics for a location and time slot are determined. A subset of advertisements is selected from a set of available advertisements based on the set of typical topics. The subset of advertisements is delivered to the at least one mass media streaming device. The mass media streaming device may be a television. A set of current topics for the location and time slot may be determined and aggregated with the set of typical topics. The subset of advertisements may be selected from the set of available advertisements based on the aggregated set.

  • Patent number: 11244013
    Abstract: The system, method, and computer program product are disclosed that track the evolution of a network over time through the analysis of media corpora associated with nodes of the network at each time slice. The media corpora may be analyzed to generate word clusters for each time slice that are then compared across time slices to determine how the network has evolved. The evolution may be tracked by determining the similarity of each word cluster of a particular time slice to each word cluster of another time slice. The similarity may be measured by a similarity score for each comparison that may be combined to determine an overall similarity of the network between the two time slices.

  • Patent number: 11030036
    Abstract: Detecting equipment failure risk in industrial process may include distributing equipment operations data to a cluster of nodes based on a range of time and operation specified in maintenance data associated with the equipment. From a record entry in the maintenance data, an operation, installation and maintenance time may be determined. A plurality of nodes storing equipment operations data associated with the operation during a time range between the installation and the maintenance time are selected. Operation features may be determined by distributed processing operation in the plurality of nodes. The operation features are aggregated and added as an entry in a target table. Equipment failure risk is detected by risk failure analysis performed based on the target table. A signal may be sent to automatically adjust or correct one or more operation features.

  • Patent number: 10756977
    Abstract: Methods and systems for determining a time dependent relevancy score of an agent node among an evolving heterogeneous network are described. A processor may expand the heterogeneous network by generating temporal heterogeneous networks representing states of the heterogeneous network at different times. The processor may extract a set of agent nodes from each temporal heterogeneous network and may generate a relationship network based on the extracted agent nodes for each temporal heterogeneous network. The processor may remove the agent node from the temporal heterogeneous network to generate a conditional relationship network excluding the removed agent node. The processor may determine a relevancy score for the agent node based on the corresponding relationship network and the conditional relationship network. Each relevancy score for the agent node may correspond to a temporal heterogeneous network and may indicate an impact of removing the agent node from the corresponding temporal heterogeneous network.

  • Patent number: 10691789
    Abstract: A processor-implemented method enables a device based on authentication of a particular user. One or more processors data mine past activities of a particular user. The past activities are detected by physical monitoring devices that monitor the particular user. The processor(s) create an authentication question and answer for the particular user based on the past activities of the particular user that the one or more processors have data mined. The processor(s) receive a request to use an electronic device used by the particular user, and then 1) transmit the authentication question to the electronic device used by the particular user and 2) receive an authentication answer to the authentication question from the electronic device used by the particular user. In response to the authentication answer from the electronic device matching the answer for the authentication question, the processor(s) remotely enable the electronic device for the particular user.

  • Patent number: 10360357
    Abstract: A method modifies a physical device for use by a particular person. One or more processors receive information from a sensor indicating a detection by the sensor of a sequence of actions performed by an unidentified person. The sequence of actions are physical actions performed in a particular order, and the physical actions are disparate types of physical movements performed by the unidentified person. One or more processors compare the sequence of actions performed by the unidentified person a known sequence of actions for a particular person. In response to the sequence of actions performed by the unidentified person matching the known sequence of actions for the particular person, one or more processors identify the unidentified person as the particular person and then modify a physical device for use by the particular person.
