A data access method in an information system including a plurality of data utilization systems connected to a network N, and a plurality of data provision systems connected to a network, wherein a data utilization system transmits a request for utilizing data in a data provision system to another data utilization system Pthrough the network N, the data utilization system, upon receipt of the data utilization request, transmits a processing execution request corresponding to the data utilization request to the data provision system through the network N, the data provision system, upon receipt of the execution request, executes processing corresponding to this execution request and transmits necessary data to the data provision system through the network, and the data provision system receives the data and stores the same.

Information system and data access method

When a remote service terminal is to be connected, the present invention executes the following procedure. The lobby terminal selects a clerk terminal which can correspond to a consulting detail and the selected clerk terminal is connected to the lobby terminal and carries out a remote consultation. When the lobby terminal selects an unattended agent server, the lobby terminal retrieves the past reply corresponding to the consulting detail of the user and displays it at the lobby terminal. When the clerk terminal corresponding to the consulting detail becomes connectable while the unattended agent server is corresponding to the user of the lobby terminal, the unattended agent server takes over the consulting detail to the clerk terminal. When there is no clerk terminal to be changed when the consultation is over, the unattended agent server sends the inquiry data which is to be replied to the user asynchronously to the clerk terminal by a communication means separately.

An information retrieval navigation method permitting either the operator or the customer not equipped with a sufficient knowledge of a given product to obtain a sufficient retrieval result is disclosed, in which at least a retrieval navigation item is generated based on the information on a plurality of cases about the product, the user is caused to select at least selected one of the retrieval navigation items, and a retrieval navigation message constituting a natural language message is generated and output from the selected retrieval navigation item. As a result, even the operator or the customer not fully equipped with the knowledge of the product can obtain a sufficient retrieval result.

Method and system for information retrieval based on parts of speech conditions

A method of actively guiding and helping the user is disclosed, in which various supporting functions can be performed in accordance with a particular user situation. The method is equipped with user situation detection data having at least a user situation and a corresponding interaction pattern activated in such a user situation, supporting function select data having at least a user situation and a corresponding user supporting function name to be activated in the particular user situation, and at least one user supporting function. Each time an input is received from the user, the contents of the input are stored as an operation log data. The interaction pattern data of the user situation detection data is compared with the operation log data. If there is any coincident interaction pattern data, the supporting function select data is retrieved with the corresponding user situation data as a key, and the corresponding supporting function name is read, thereby activating the supporting function associated with the particular supporting function name.

A computer in a securities dealing decision support system is connected via a communication line to a dealer/trader terminal device and customer terminal device. A voice communication line is connected between the dealer/trader terminal device and customer terminal device. The information generated at the computer is outputted to both the terminal devices at the same time. The customer can decide the securities dealing by using the voice communication line while looking at the same information as that for the dealer/trader.

Computer aided real-time decision support system and method

A fuzzy evaluation and modification system evaluates and modifies the fuzzy knowledge in a fuzzy reasoning system. The fuzzy knowledge includes fuzzy rules, each described in an 'if . . . , then . . .' format, and membership functions defining meanings of propositions described in the 'if . . . , then' parts. Results of the fuzzy reasoning are monitored and compared with real data of a plurality of real test cases to evaluate the fuzzy knowledge. An influence power of each of the fuzzy rules with respect to the fuzzy reasoning results is attained for all the cases. Superpositional display of real data on the membership functions of the 'if . . .' part and reasoning results on the membership functions of the 'then . . .' part indicates a relationship between the membership function and the real data. The system includes units for obtaining a grade of rule representing adequacy of the fuzzy rule based on the membership functions associated with the 'if' part, attaining defuzzification values of the membership functions related to the 'then' part and obtaining differences between the defuzzification values and the real data. A relationship between the grade of rule and the difference thus obtained between the defuzzification values and the real data is outputted to an output unit. The fuzzy knowledge is modified by an operator in association with the output.

Method and system of selecting desirable time series data pieces from many time series data pieces. Characteristics extracted from time series data pieces are applied to neurons and neuron state fluctuations are supervised and evaluated through execution of neurocomputing to select desirable time series data.

Method and a system for selection of time series data

In an nuclear magnetic resonance imaging system for acquiring a tomographic image of an object of interest at a high speed by use of time-varying gradient magnetic fields, a weighting factor is used in reconstructing an image through the calculation of a correlation of data of a detected nuclear magnetic resonance signal with data of a reference signal, thereby controlling the point spread function and/or the signal-to-noise ratio in each point on the reconstruction image. Also, the effect of relaxation, chemical shift and/or static magnetic field inhomegeneity, which would otherwise degradate the image quality, can be corrected. Further, a velocity of the object of interest at each point on the reconstruction image can be measured.

Several properties are assigned to the regions of an image having light and shade and obtained by photographing a surface of an object. Several properties are also assigned to the regions of the picture, which are extracted on the basis of the first proper-assigning operation, and the boundary lines therebetween. The angles of inclination of these regions and the condition of the unevenness of the regions of the surface which are on these boundary lines are estimated by utilizing the relation between the above-mentioned properties and the direction of a light source. Thus, the relative elevation of the surface of the object is determined. The above-mentioned properties are determined with respect to images of the same object from different directions, and the properties thus determined of these images are compared to determine the corresponding points, which are utilized to determine the quantitative elevation of the surface.

Method of and apparatus for detecting heights of points on surface of

By using a low-frequency component of attitude data of an uncorrected image resulting from scanning the ground by means of a sensor mounted on a satellite, low-frequency distortion correction coefficients are calculated. By using a high-frequency component of attitude data, a change rate is calculated. From said low-frequency distortion correction coefficients and said change rate, distortion correction coefficients covering a high frequency are calculated. By applying bidirectional resampling to the uncorrected image by using said distortion correction coefficients covering a high frequency, a corrected image is obtained.
