A similarity calculation unit () treats each of a plurality of classifications as a target classification, and calculates a similarity between a reference feature value, which is a feature value extracted from image data of the target classification, and a recognition feature value, which is a feature value extracted from recognition target data, which is image data to be recognized. An influence calculation unit () calculates an influence on the similarity with regard to each partial image of the recognition target data by taking as input the similarity with regard to each of the classifications and the recognition feature value. A feature identification unit () changes the recognition feature value in accordance with the influence.

Feature identification device, feature identification method, and computer readable medium

In an entry field extraction device, a learning unit obtains a learning model by learning, from images of a plurality of documents, features corresponding to types of the documents. A feature field extraction unit extracts, from an image of a document sample, a feature field being a field indicating a feature corresponding to a type of the document sample, using the learning model. An entry field extraction unit extracts an entry field, being a field of an entry column, from a field that remains in the image of the document sample from which the feature field extracted by the feature field extraction unit has been excluded.

Entry field extraction device and computer readable medium

In a virtual computer system controlling a disk volume and a virtual server which is connected to the disk volume, to which the area of the disk volume is allocated as a virtual disk and which executes a process using the allocated virtual disk, the virtual computer system erases information stored in the virtual disk allocated to the virtual server to be deleted correspondingly with the deletion of the virtual server. An administrative server may be provided to select a server system which is low in load from among plural server systems controlling virtual servers as a server system for erasing information stored in the virtual disk allocated to the virtual server to be deleted.

Virtual computer system and method of controlling the same

In the environment of a virtual server, there is a problem in that the contents in a disk area released correspondingly with the deletion of the virtual server may be read. According to the present invention, in a virtual computer system controlling a disk volume and a virtual server which is connected to the disk volume, to which the area of the disk volume is allocated as a virtual disk and which executes a process using the allocated virtual disk, the virtual computer system erases information stored in the virtual disk allocated to the virtual server to be deleted correspondingly with the deletion of the virtual server. According to another embodiment of the present invention, an administrative serve is provided to select a server system which is low in load from among plural server systems controlling virtual servers as a server system for erasing information stored in the virtual disk allocated to the virtual server to be deleted.

Method and system for deleting low-load allocated virtual server resources

In a virtual computer system controlling a disk volume and a virtual server which is connected to the disk volume, to which the area of the disk volume is allocated as a virtual disk and which executes a process using the allocated virtual disk, the virtual computer system erases information stored in the virtual disk allocated to the virtual server to be deleted correspondingly with the deletion of the virtual server. According to another embodiment of the present invention, an administrative server is provided to select a server system which is low in load from among plural server systems controlling virtual servers as a server system for erasing information stored in the virtual disk allocated to the virtual server to be deleted.
