Latest Patents

One of her latest patents is titled "Tracking the evolution of topic rankings from contextual data." This patent discloses a system, method, and computer program product that tracks the evolution of a network over time by analyzing media corpora associated with nodes of the network at each time slice. The analysis generates word clusters for each time slice, which are then compared across time slices to determine how the network has evolved. The evolution is tracked by measuring the similarity of each word cluster of a particular time slice to those of another time slice, resulting in a similarity score that indicates the overall similarity of the network between the two time slices.

Another notable patent is "Node relevance determination in an evolving network." This patent describes methods and systems for determining a time-dependent relevancy score of an agent node within an evolving heterogeneous network. A processor expands the heterogeneous network by generating temporal heterogeneous networks representing different states of the network over time. The processor extracts a set of agent nodes from each temporal heterogeneous network and generates a relationship network based on these nodes. By removing an agent node from the temporal heterogeneous network, a conditional relationship network is created, allowing the processor to determine a relevancy score for the agent node based on the corresponding relationship networks.
