摘要： PROBLEM TO BE SOLVED: To prevent false recognition of tampering of a document.
SOLUTION: A document creation assist system 101 creates a document for which forgery and tampering of data can be detected, by extracting, from a created document, document features of a pixel specified in a tampering detection region defined as a region from which document features are to be extracted and recording the document features in the document. The document creation assist system 101 extracts a plurality of document features of the pixel specified in the tampering detection region. It also extracts the plurality of document features after converting the specified pixel using an image conversion algorithm based on the information relating to the tampering detection region. Then it calculates a difference between the document features not subjected to image conversion and the document features subjected to image conversion. The difference is input into an evaluation function determined according to the image conversion algorithm, and the obtained value is an evaluation score of the document features. Which document feature is selected as a document feature of the pixel in the tampering detection region from among the plurality of document features is determined based on the evaluation score.

摘要： PROBLEM TO BE SOLVED: To provide a time map that changes by a time zone and means of transportation on the basis of a time distance from a reference point to a real estate object whereas an effective method has not been available before for arranging an object having a plurality of attributes, such as time spent in commuting and going to school, house rent and a room layout. SOLUTION: This method calculates a distance from the reference point to the target on the basis of one attribute or more about the target having a plurality of attributes and arranges the target on the basis of the distance. For instance, in the case of a system that evaluates and supports a real estate object, the system calculates a time distance up to the real estate object by taking the transfers of various means of transportation, the last train of the day, the last but of the day, waiting time, etc., into consideration on the basis of a reference point, a time zone and available means of transportation designated by a user and prepares and offers a customized time map to each user.

摘要： PROBLEM TO BE SOLVED: To improve convenience by presenting a logical structure related with resource arrangement, and making the expressing method suitable to the desire of a user. SOLUTION: A navigation information address management table 301 is constituted of three fields, that is, a type 302, name 303, and data logical address 304. A tree type, tour type, or link type is described in the type. The leading address of a list structure is stored in the data logical address 304. Thus, navigation information in which the semantic arrangement structure of a resource is described can be automatically generated by a tree detecting processing, tour detecting processing, and link detecting processing for following a hyper link, and detecting the type of the information. The generated navigation information is transferred through a network, and stored so that the navigation information can be quickly referred to as a local file. Thus, the arrangement of plural resources is exactly displayed to a user so that the user can obtain the address of the desired resource.

摘要： PURPOSE:To provide the method for directing the rotation of the three- dimensional object capable of easily setting the three-dimensional coordinates required to control the three-dimensional rotation by using the two-dimensional input device. CONSTITUTION:When the direction inputted from the mouse by a user is accepted, a rotating shaft r 105 and a rotating angle theta 106 which rotate the object three-dimensionally are calculated. In this case, the direction of the three- dimensional rotating shaft 105 is obtained from the normal direction of the plane decided by two points P1 and P2 located on a display 101 and a viewpoint 102 and the rotating angle theta 106 is decided from the distance between two points. Thus, the user can give the object a desired rotation to the object by simply 'rotating by holding with the mouse' a corner of the object displayed on the display device.
