Abstract

This invention concerns a network server operable to run an application and communicate using question and answer sessions to provide answers to users questions. In particular it concerns such a server equipped to deal with the situation where it is unable to provide an answer from the application as it exists at that time. To do this the server initiates and controls a knowledge extending question and answer session to add the answer to the application. In a further aspect it concerns a method of operating such a server.

Claims

1. A network server operable to run an application and communicate using question and answer sessions to provide answers to users questions, where the application makes use of a knowledge base having:

a problem context in which there are patterns of problem objects, a solution context in which there are patterns of solution objects, and mappings between problem patterns in the problem context and solution patterns in the solution context; and

in which knowledge is defined by the mappings; and

where the server is further operable in the event no pattern exists to give an answer to a question, to initiate a knowledge extending question and answer session in which an expert sets up new contexts and mappings to create an answer to that question.

2. A network server according to claim 1, where the server controls the knowledge extending session to constrain the contexts and mappings to conform to server requirements.

3. A network server according to claim 1 or 2, where the objects are arranged in a hierarchy.

4. A network according to claim 1, 2 or 3, where the objects in both the problem and solution contexts have a title, explanation and values.

5. A network server according to any preceding claim, where the answers to questions are provided by information associated with objects in the problem space.

6. A network server according to any preceding claim, where the knowledge is stored in a database.

7. A network server according to any preceding claim, where, in response to a question, a client receives a series of further questions from the server to enable a client to refine the question to the point where it can be answered.

8. A network server according to claim 7, where the further series of questions are ordered according to their importance in searching the data, the information gained from the session so far, and the knowledge in the knowledge base.

9. A network server according to any preceding claim, where a knowledge extending session takes place between the server and an expert client.

10. A method of operating a server runing an application and communicating using question and answer sessions to provide answers to users questions, where the application makes use of a knowledge base having:

a problem context in which there are patterns of problem objects;

a solution context in which there are patterns of solution objects, and mappings between problem patterns in the problem context to solution patterns in the solution context; and

in which knowledge is defined by the mappings; and

, where no pattern exists to enable the server to give an answer to a question from a client, the method involving the step of;

initiating a knowledge extending question and answer session in which an expert sets up new contexts and mappings to create an answer to that question.

11. A method according to claim 10, where the server controls the knowledge extending session to constrain the contexts and mappings to conform to server requirements.

12. A method according to claim 10 or 11, where the server answers questions by providing information associated with objects in the problem space.

13. A method according to claim 10, 11 or 12, where, in response to a question, a client receives a series of further questions from the server to enable a client to refine the question to the point where it can be answered.

14. A method according to claim 13, where the further series of questions are ordered according to their importance in searching the data, the information gained from the session so far, and the knowledge in the knowledge base.

15. A method according to any one of claims 10 to 14, where a knowledge extending session takes place between the server and an expert client.
