  • Patent number: 11940962
    Abstract: A method for creating a database for a domain specific application includes providing a centralized data repository comprising data from different sources, identifying a set of data units of the repository that represent a specific domain, determining a pivotal entity type for an application, determining a mapping between different identifiers of the pivotal entity type, creating a reference set by selecting a first subset of the set of data units using the mapping, wherein the first subset represents the pivotal entity type, selecting, based at least in part on the mapping, a second subset of the set of data units, wherein the second subset represents non-pivotal entity types which are related to instances of the pivotal entity type in the reference set; and creating a database from data units and associated attributes selected from the reference set of data units and the second subset of data units.

  • Publication number: 20230252078
    Abstract: A computing system, program products and computer-implemented method of exploring data comprises accessing data structures and executing an interaction loop. Data structure captures connected graph nodes associated with attributes containing human-readable data. Interaction loop receives user-selected attributes associated with focal nodes and executes subroutines to determine layouts of an arborescence extending from focal nodes. The subroutines use starting nodes and pivot attributes as arguments. Identifying nodes of subroutines are connected to starting nodes by walking the graph and comparing pivot attributes with attributes associated with connected nodes, obtaining distance-dependent quantities. Subroutines compute layout data, including coordinates of the connected nodes. Coordinates are determined in accordance with the distance-dependent quantities. Interaction loop displays arborescence according to the layout data.

  • Patent number: 10891319
    Abstract: Real-time rendering representations of objects in a view. Objects include clusters of nodes of a graph structure and links between said clusters. The graph structure comprises edges defined as pairs of the nodes. User inputs in respect to a current view and/or at least one of the objects is received. A data structure is updated, which associates multiple identifiers. Multiple identifiers may include cluster identifiers, node identifiers, and link identifiers, which respectively identify clusters of nodes, nodes of said graph, and links between pairs of clusters.
