  • Patent number: 12259920
    Abstract: Disclosed embodiments provide techniques for monitoring and evaluating the effectiveness of key value pairs (KVPs) used in a document processing system. In embodiments, KVPs are obtained from multiple extractors of a document processing system. A score is computed for the KVPs by computing an effectiveness metric for each KVP from the multiple KVPs. In response to the computed score being below a predetermined threshold, a model retraining process is performed to generate a new set of KVP extractors, and provide the new set of KVPs to the document processing system.

  • Publication number: 20250053746
    Abstract: Disclosed embodiments provide techniques for creating a smaller version of an original document. An ontology is defined, and a document type for an original document is determined, based on the ontology. Multiple key-value pairs (KVPs) are extracted from the original document based on the document type. Pages in the original document that include one or more KVPs are identified, and the smaller, condensed version includes the identified pages from the original document.

  • Patent number: 11842143
    Abstract: A method, computer system, and a computer program product is provided for generating a detailed thumbnail and/or preview of a content. In one embodiment the technique comprises analyzing data obtained from a content and classifying it according to a plurality of specific types. A plurality of key information may be then extracted from the data according to the classification. A plurality of key-values are correlated to the plurality of key information so as to provide a plurality of key-value pairs. These pairs are consolidated accordingly to generate a thumbnail and/or a preview that at least renders the key information provided by the consolidated key-value pairs as a rendering.

  • Publication number: 20220309072
    Abstract: A computer transforms content of a composite table into structured data objects. The computer receives a composite table and identifying a data zone characterized by data columns, and a header zone. The computer identifies first header cells arranged coextensive with a single data column and second header cells arranged coextensive with a set of data columns. The computer generates a hierarchical representation of said header cells, based at least in part, on the header cell arrangements. The computer generates a revised table based on the hierarchical representation, with the first header cells identifying a data column and the second header cells identify a first header cell. The computer generates structured data objects representing the zones and being arranged based, at least in part, on the revised table and where the structured data objects are keyed to the first header cells.

  • Patent number: 11175804
    Abstract: The present disclosure relates to a method and system for deploying user interface elements on a screen which has broken-faulty regions on the screen. One or more broken-faulty regions are detected on the screen. At least a part of the normal regions on the screen is determined to be a region for displaying at least a part of one or more user interface elements which are related to the one or more broken-faulty regions. The at least a part of the one or more user interface elements are deployed on the screen based on the result of the determining.
