  • Patent number: 10783366
    Abstract: A computer that extracts an attribute which is a text string contained in an predetermined examination target document stores template information for managing a plurality of templates in which a type of attribute is defined, executes a text recognition process on image data of the document, extracts an attribute corresponding to the type of attribute using a result of the text recognition process and the plurality of templates, selects a template based on the extracted attribute, generates output information that includes the attribute extracted using the selected template and is used for the examination; determines a type of confirmation operation performed on the output information, before the examination, based on a comparison result between an evaluation value indicating credibility of the output information and a threshold, and corrects the determined type of confirmation operation based on the text string contained in the document.

  • Publication number: 20190286692
    Abstract: A computing machine managing a template manages a document format, a template, and a cluster generated on the basis of a classification result based on a position of the document in a feature space in such a manner that they correspond to one another; determines whether a cluster to which a target document can belong is present on the basis of a position, in the feature space, of the target document in a case of detecting an opportunity of generating a template of the target document; registers the template of the target document in a case of determining that the cluster to which the target document can belong is not present; generates a cluster corresponding to the registered template; and manages a document format of the target document, the registered template, and the generated cluster in such a manner that they correspond to one another.

  • Patent number: 8234584
    Abstract: Provided is a computer system including an information providing server and a computer which is coupled to the information providing server, and which collects information, the computer being configured to: record status histories including a history of an operation to a screen which shows a status of the computer, and which is displayed on the computer in chronological order to constitute a set of the status histories; and divide, in a case where a history of an operation of switching the screen is detected from the set of the status histories, based on the history of the operation of switching the screen, the set of the status histories. Accordingly, when a user collects information, navigation information is provided by taking the fact that the user has actually reached useful information into consideration.

  • Publication number: 20110137836
    Abstract: Disclosed are method and system for generating history of behavior that is capable of simplifying input of a behavior content of a human behavior pattern determined from data measured by a sensor. A computer obtains biological information measured by a sensor which is mounted to a person and accumulates the biological information, obtains motion frequencies from the accumulated biological information, obtains time-series change points of the motion frequencies, extracts a period between the change points as a scene which is a period of being in the state of an identical motion, compares the motion frequencies with a preset condition for each extracted scene and identifies the action contents in the scene, estimates the behavior content performed by the person in the scene on the basis of the appearance sequence of the action contents, and generates the history of the behaviors on the basis of the estimated behavior contents.

  • Patent number: 7693675
    Abstract: Methods of confidential data sharing and mutual authentication between a sensor node and a router are established, and data in the sensor node is protected from a physical attack. Sensor node issuing processing is performed on a sensor node having a tamper resistant device. The sensor node issuing processing is processing in which data and a function that are deactivated are loaded in the tamper resistant device of the sensor node from the time of manufacture of the sensor node to the time the sensor node reaches a system that runs the sensor node. Activation data is used to activate the deactivated data and function. The activation data is shared between stages of the issuing processing with the use of a data management system.

  • Patent number: 7587200
    Abstract: A computer system including wireless terminals which transmit information, a business application server which performs a predetermined operation based on information received from the wireless terminals, and a base transceiver station which relays communications between the wireless terminals and the business application server, are provided. The base transceiver station, to manage said plural wireless terminals in groups, stores a group definition table showing a correspondence between the wireless terminals and the groups, stores the information received from the terminals in a state history table which manages the state history of the wireless terminals, extracts difference information between the information received from the wireless terminals and the information stored in the state history table, summarizes the extracted difference information for each group, and transmits it to the business application server. The data amount received by a business application server is thus reduced.

  • Patent number: 7587221
    Abstract: An attribute value of a matter accompanied by a sensor is transmissibly accessible in a sensor node system constituted by wireless terminal computers having the sensor, the wireless communication base stations and server computers. The wireless terminal computer reports at the time of wireless communication an identification number of a wireless communication base station with which it communicates previously. A relay processing service is dynamically constituted so that when a wireless communication base station different from itself is reported, the wireless base station as the communication counter-part can transmissbly look up the wireless terminal computer from a host computer.
