Latest Patents

One of her latest patents is titled "Methods and systems for extracting information from document images." This invention relates to a method and system for extracting information from images of one or more templatized documents. A knowledge graph with a fixed schema based on background knowledge is utilized to capture spatial and semantic relationships of entities present in scanned documents. An adaptive lattice-based approach based on formal concepts analysis (FCA) is employed to determine a similarity metric that utilizes both spatial and semantic information. This method helps in identifying if the structure of the scanned document image adheres to any known document templates. If a matching template is detected, an inductive rule learning-based approach is used to extract information from the scanned document image. If a new document template is identified, future scanned document images belonging to that template are automatically processed using the learned rules.

Another significant patent is "Method and system for generating a response to an unstructured natural language (NL) query." This invention addresses the challenges faced by systems that handle unstructured NL queries. The system collects at least one NL query as input and generates a sketch, which is a structured representation of the unstructured query. By processing the sketch, the system generates one or more database queries to search in associated databases and retrieve matching results. These results are then used to generate a response to the NL query.
