  • Publication number: 20230359828
    Abstract: An information processing apparatus for converting text data from a document image read from a document into a token string and calculates a number of processing times necessary for performing processing in a natural language processing model based on the token string. Then, at the time of division, the information processing apparatus divides the token string into blocks so that at least a portion overlaps between adjacent blocks based on the calculated number of processing times and for each token belonging to the overlap portion between the adjacent blocks, selects one of estimation results obtained from each block.

  • Publication number: 20230186028
    Abstract: The present disclosure relates to a technique of generating a disclosable document image based on a document image including confidential information, without using the confidential information. A document input unit obtains a document image scanned with a scanner, separates the document image into character information and background information, and then outputs them to an extraction unit. The extraction unit performs named entity extraction processing on the obtained character information and background information to extract named entities in the document and attributes thereof, and output an extraction result to a generation unit. The generation unit replaces the named entities in the document image with attribute tags and obtains superimposable ranges to generate attribute tag document data. A management unit registers the received extraction result of the named entities and the attribute tag document data in a database.
