  • Publication number: 20230083959
    Abstract: Provided is an information processing apparatus that extracts a character string to be a candidate of an item value corresponding to a predetermined item, from among multiple character strings included in a document image to be processed. The information processing apparatus first obtains information indicating a conceptual feature group of a preset extraction target, then identifies a conceptual feature group to which each of the character strings included in the document image to be processed belongs from among predetermined multiple conceptual feature groups based on a feature vector corresponding to each character string, and then extracts the character string whose identified conceptual feature group is the same as the conceptual feature group associated with the same attribute information as the conceptual feature group of the extraction target, from among the character strings included in the document image, as the candidate.

  • Patent number: 9689729
    Abstract: A small and light-weight flowmeter realizes the compensation of a zero point drift. A mass flowmeter includes: a centrifugal force/centripetal force detection strain gauge adhered to a part acted upon by a centrifugal force or a centripetal force of fluid in a pipe line in which the fluid flows and a flow rate zero point drift compensation strain gauge adhered to a position different from that of the centrifugal force/centripetal force detection strain gauge. A pulse wave propagation time between the two points is used to compensate a zero point drift of a flow rate.

  • Patent number: 8954845
    Abstract: A region division portion extracts an “object”, an “anchor expression accompanying the object” and a “text including the anchor expression” from image data based on a paper document and an electronic document. A link processing portion generates link information that associates, in two ways, the “object”, the “anchor expression included in the text” or the “text including the anchor expression” with each other. Then, a format conversion portion converts the link information into electronic document data including two-way link information. When this electronic document data is displayed by an application and one of the “object” and the “anchor expression included in the text” is selected, the other can be displayed according to the link information.

  • Patent number: 8614838
    Abstract: According to the present invention, it is possible to create electronic document data capable of highlighting an object detected through a search so that a user can easily recognize it. An image processing apparatus extracts an object from an input image and extracts metadata related to the object. The image processing apparatus, when determines to describe with a shape in accordance with the shape of the object, creates a vector path description of frame described with a shape in accordance with the shape of the object. Then, the image processing apparatus creates an electronic document including data of the input image and the vector path description of frame with which the metadata is associated. When a keyword search is performed on the created electronic document, highlight display is performed in accordance with the vector path description of frame with which metadata that matches the keyword is associated.
