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.

Computing machine and template management method

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.

Computer and document identification method

A computer, which is configured to extract an attribute being a character string indicating a feature of a paper-based document, the computer stores template information dictionary information. The computer is configured to: execute character recognition processing on image data on the paper-based document; extract an attribute corresponding to each of the at least one type of attribute, which is defined in each of the plurality of templates, through use of a result of the character recognition processing and the plurality of templates; calculate a score regarding the extracted attribute for each of the plurality of templates; select one of the plurality of templates that has the highest extraction accuracy of the attribute based on the score; and generate output information through use of the selected template.

Computer, document identification method, and system

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.

Computer system, information collection support device, and method for supporting information collection

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.

Method for protection of sensor node's data, a systems for secure transportation of a sensor node and a sensor node that achieves these

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.

Computer system and base transceiver stations

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.
