  • Patent number: 9208535
    Abstract: A method, non-transitory computer readable medium, and apparatus for large-scale web community detection using a graphical processing unit (GPU) are disclosed. For example, the method receives an input graph formatted into one or more first adjacency lists from a central processing unit (CPU), performs a first level shingling on the one or more first adjacency lists, sends the first level shingling to the CPU to generate an aggregate graph based upon the first level shingling, receives the aggregate graph formatted into one or more second adjacency lists from the CPU, performs a second level shingling on the one or more second adjacency lists and sends the second level shingling to the CPU to generate a dense sub-graph that identifies one or more web communities.

  • Publication number: 20140310053
    Abstract: A system and method for providing a real-time business process suggestion and recommendation utilizing a business process modeler. A dynamic input from a business analyst can be incorporated utilizing a real-time suggestion engine. A real-time search can be performed by organizing a number of business processes in a tree structure where each leaf node represents a business process and each branch node represents a set of components that are shared by the business processes in a sub tree. A semantic execution path search can be performed to provide a real-time match between the partial business process and a catalogue of existing business processes by determining a constituent component and a score based on a reachability rule. The edges and/or components can be added and/or deleted to effectively organize the existing business processes based on previous suggestion to speed up a future suggestion.
