Abstract: PROBLEM TO BE SOLVED: To enable a user not to concentrate on a specified machine for generating the presentation of information but to concentrate on the answer of a question supported by an interface. SOLUTION: While using an expandable natural word, an inquiry based on the natural word is expressed by converting it to the set of a data base inquiry and information to be provided to the user. Concretely, concerning the natural word inquiry, it is determined whether a complete data base inquiry can be formed on the basis of the natural word inquiry or not and when the inquiry can be formed, by specifying which complete data base inquiry is to be formed, the natural word inquiry is converted to the data base inquiry.

Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for providing interactive service with multiple interfaces. SOLUTION: The interactive service using module technique is provided. Support of understanding and dialogue of natural languages with a user is facilitated by applying the technique to an interface to enable inputs in different order, incomplete information, correction of information and return of control to the previous service event. The support is realized by using single interactive service logic using a reaction restriction graph. A node includes a restriction set regarding events in the graph. Specifically, the control proceeds from the node to a derivative node only when all restrictions in the set are satisfied. The incomplete information and the correction of information are supported respectively by supporting the input in different order, in addition, promptly evaluating the restrictions in the set and updating information in the set when a new piece of information is received by a single restriction set. Labeling to the node and the return of control to the previous node are enabled by using the graph.

Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for providing an interactive service with plural interfaces. SOLUTION: Support of understanding and dialogue of a natural language with a user is facilitated by enabling the user to provide information to exceed the one to be required for service and adapting a module technique to an interface 204 to enable an input in different order, incomplete information, correction of the information and return of control to the previous service point. The support is realized by using a single interactive service logic 201 using a reaction restriction graph in relation to a service monitor 202. Bi-directional service logic structure to use a form of a graph of event drive including restriction to an event in a node is adopted in the graph. This service monitor manages communication between a service logic device and the plural user interfaces and provides communication mechanism in a form called 'look ahead'.
