An extracted hypothesis has logical formulas leading to a possible conclusion. If the logical formulas include one including a first parameter a value obtained from observation data and a second parameter that does not have a value obtained from the observation data, the logical formula is set as a target logical formula, and a value of the second parameter acquired based on the observation data is input. If there is no such logical formula, but there is a logical formula that has, for one or more parameters, a value set in advance or obtained using inference knowledge, whether this logical formula is true or false is determined. When whether the logical formula is true or false is determined, or, when the value of the second parameter is input, the logical formula is added to the observation data, and a hypothesis is derived again.

A data classifier system of the present invention selects a plurality of classifications correlated to data groups so as to output classification axes based on hierarchical classifications and data groups. The data classifier system includes a basic category accumulation means, a classification axis candidate creation means and a priority calculation means. The basic category accumulation means accumulates classifications serving as basic categories used for selecting desired classifications in advance. The classification axis candidate creation means creates classification axis candidates based on combinations of classifications each correlated to at least one data among descendant classifications of each basic category. The priority calculation means calculates priorities with respect to the classification axis candidates created by the classification axis candidate creation means based on hierarchical distances of classifications in the classified hierarchy.

A data classifier system of the present invention selects a plurality of classifications correlated to data groups so as to output classification axes based on hierarchical classifications and data groups. The data classifier system includes a basic category accumulation means, a classification axis candidate reduction means and a priority calculation means. The basic category accumulation means accumulates classifications serving as basic categories used for desired classifications in advance. The classification axis candidate reduction means selects a plurality of classifications from among classifications descendant from each basic category so as to create classification axis candidates, thus reducing classification axis candidates subjected to calculations based on data quantity of classifications and hierarchical distances of classifications. The priority calculation means calculates priority in displaying classification axis candidates, the number of which is reduced by the classification axis candidate reduction means.

To provide a technique for structuralizing ontology in a prescribed form to a structure to which features of data are reflected. An ontology processing device has a structuralizing device for structuralizing properties of the ontology in the prescribed form generated from a set of instance data containing a combination of a subject, a property, and an object expressed with a character string according to the features of the object, and has a ontology storage device which stores the ontology structuralized by the structuralizing device. With this structure, the properties of the ontology in the prescribed form are corrected or expressed as an ontology structure by reflecting the characteristics of a set of the objects obtained from the data.

A website access system allowing easy operation and a small number of steps for accessing a desired one of a great number of websites is disclosed. A plurality of domain areas are provided, which is determined so that a number of information providers is restricted. An address registration database retrievably registers a plurality of address identifiers uniquely identifying respective ones of website addresses which have been registered for each of the domain areas. An access management server receives an address identifier from the user terminal located in one of the domain areas, searches the address registration database for a corresponding website address according to the address identifier and the domain area where the user terminal is located, and then uses the corresponding website address to make the user terminal access the desired website on the network.

In a case where computer software containing a plurality of objects is displayed on a display device, a structure of to-be-displayed objects is analyzed, and, for example, the analyzed structure which is represented in a tree structure is retained in an object structure retaining section. A required area calculating section obtains a size of an area required for displaying the objects in the structure which is retained by the object structure retaining section, and an area comparing section compares the obtained size of the required area with a size of a displayable area which is pre-stored. An alignment change process determining section determines whether to change an alignment of the objects, based on the comparison result. If the alignment change process determining section determines not to change the alignment, computer software in the structure of the objects is displayed on the display device. On the contrary, if the alignment change process determining section determines to change the alignment, an alignment changing section changes the structure of the objects for performing the same process based on the changed structure of the objects. Not only the alignment of the objects, a size of one or more than one object may be changed.

An information providing system is mainly configured by a terminal and an information storage equipment. The terminal is manipulated by a user to issue an information obtainment request, wherein it has a specific output condition, which is defined by a picture output function and/or a sound output function. The information storage equipment extracts a number of digital information elements to suit the information obtainment request, so that the digital information elements are synthesized together into digital information in accordance with a default (information) providing manner, which represents a specific display screen whose screen size and layout are determined in advance. Then, the digital information is transmitted to the terminal, which in turn provides the user with content of the digital information by using pictures and/or sounds. If the default providing manner does not match with the output function of the terminal, the information storage equipment changes the default providing manner by one of change methods, which is selected in consideration of the preset priority. Thus, the digital information elements are synthesized together into the digital information in accordance with the changed providing manner. Incidentally, if the terminal does not have a necessary software module required for outputting the digital information, the terminal downloads it from its resource.
