Abstract

There are provided a dialog control system and a dialog control method for realizing a smooth dialog dynamically corresponding to contents of a natural dialog by a user without allowing the user to be aware of an operation history. The dialog control system interprets the input information input by the user, identifies a plurality of dialog agents for responding to the input information, transmits the input information to the dialog agent to request a response to the input information, and outputs a response from the dialog agent. Processable information is inquired about with respect to a plurality of dialog agents. The input information is matched with the processable information. A dialog agent capable of processing the input information is selected. The input information is transmitted to the selected dialog agent, and a dialog control part receives a response thereto.

Claims

1. A dialog control system, comprising:

an input part for interpreting input information input by a user;

a dialog agent for responding to the input information; and

a dialog control part placed between the dialog agent and the input part, for identifying a plurality of the dialog agents, transmitting the input information to the dialog agent to request a response to the input information, and transmitting a response from the dialog agent to an output part,

wherein, when the input information is input, the dialog control part inquires about processable information with respect to the plurality of dialog agents, stores the processable information, matches the input information with the processable information, selects the dialog agent capable of processing the input information, and transmits the input information to the selected dialog agent to receive a response thereto.

2. The dialog control system according to claim 1, wherein the dialog control part previously stores identification information of the dialog agents and selection priority of the dialog agents so that the identification information is associated with the selection priority, refers to the dialog agents in a decreasing order of the selection priority when referring to the input information and the processable information, and transmits the input information to the first selected dialog agent to request a response to the input information.

3. The dialog control system according to claim 2, wherein the dialog control part accumulates identification information of the dialog agent selected as a transmission destination of the input information, refers to the first stored dialog agent when selecting the subsequent dialog agent, in a case where the stored dialog agent is capable of processing the input information, transmits the input information to the stored dialog agent to request a response to the input information, and in a case where the stored dialog agent is not capable of processing the input information, refers to the dialog agents in a decreasing order of the selection priority.

4. The dialog control system according to claim 2, wherein the selection priority of the dialog agent is automatically updated in accordance with a use frequency.

5. The dialog control system according to claim 3, wherein the selection priority of the dialog agent is automatically updated in accordance with a use frequency.

6. The dialog control system according to claim 2, wherein, in the dialog control part, the control agents to be referred to are narrowed in accordance with contents of the input information, and the narrowed dialog agents are referred to in a decreasing order of the selection priority.

7. The dialog control system according to claim 3, wherein, in the dialog control part, the control agents to be referred to are narrowed in accordance with contents of the input information, and the narrowed dialog agents are referred to in a decreasing order of the selection priority.

8. The dialog control system according to claim 4, wherein, in the dialog control part, the control agents to be referred to are narrowed in accordance with contents of the input information, and the narrowed dialog agents are referred to in a decreasing order of the selection priority.

9. The dialog control system according to claim 1, wherein the dialog control part stores the identification information of the dialog agent determined to be available based on the processable information on a basis of the dialog agents, and the dialog control part inquires about the processable information with respect to only the dialog agent determined to be available.

10. The dialog control system according to claim 2, wherein the dialog control part includes a user information input part for inputting information for identifying a user, stores input information for identifying the user and information on a state using the dialog agent including the selection priority on a user basis, and performs processing in accordance with the selection priority on a user basis.

11. The dialog control system according to claim 3, wherein the dialog control part includes a user information input part for inputting information for identifying a user, stores input information for identifying the user and information on a state using the dialog agent including the selection priority on a user basis, and performs processing in accordance with the selection priority on a user basis.

12. The dialog control system according to claim 4, wherein the dialog control part includes a user information input part for inputting information for identifying a user, stores input information for identifying the user and information on a state using the dialog agent including the selection priority on a user basis, and performs processing in accordance with the selection priority on a user basis.

13. The dialog control system according to claim 5, wherein the dialog control part includes a user information input part for inputting information for identifying a user, stores input information for identifying the user and information on a state using the dialog agent including the selection priority on a user basis, and performs processing in accordance with the selection priority on a user basis.

14. The dialog control system according to claim 6, wherein the dialog control part includes a user information input part for inputting information for identifying a user, stores input information for identifying the user and information on a state using the dialog agent including the selection priority on a user basis, and performs processing in accordance with the selection priority on a user basis.

15. A dialog control method, comprising:

inquiring about processable information with respect to a plurality of dialog agents making responses corresponding to input information, and storing obtained processable information;

interpreting input information input by a user;

matching the input information with the processable information, selecting the dialog agent capable of processing the input information, and transmitting the input information to the selected dialog agent to request a response to the input information; and

receiving the response from the dialog agent and outputting it.

16. A program product storing a program on a recording medium, the program allowing a computer to execute the operations of:

inquiring about processable information with respect to a plurality of dialog agents making responses corresponding to input information, and storing obtained processable information;

interpreting input information input by a user;

matching the input information with the processable information, selecting the dialog agent capable of processing the input information, and transmitting the input information to the selected dialog agent to request a response to the input information; and

receiving the response from the dialog agent and outputting it.
