Abstract

A method and apparatus in a data processing system for data content retrieval comprises steps and methods for receiving a user request; generating a first query according to the user request; querying a first database using the first query to generate a first query request; generating a second query according to the first query request; querying a second database using the second query to generate a second query request; and responding to the user request with a response according to the second query request. The method and apparatus further comprises steps and methods for filtering the second query request to generate the response, where the filtering of the second query request is according to relevance to the intent of the user request and where the second query request is filtered according to a device type.

Claims

1. A method in a data processing system for content retrieval, comprising the steps of:

receiving a user request;

generating a first query according to the user request;

querying a first database using the first query to generate a first query request;

generating a second query according to the first query request;

querying a second database using the second query to generate a second query request.

2. The method of claim 1, further comprising the steps of:

responding to the user request with a response according to the second query request;

and filtering the second query request to generate the response.

3. The method of claim 2, wherein filtering of the second query request is performed according to relevance of the intent of the user request.

4. The method of claim 3, wherein the second query request is filtered according to a device type.

5. The method of claim 3, wherein the second query request is filtered according to a preference.

6. The method of claim 5, wherein the preference is indicated in a previous history, geographical location and temporal changes.

7. The method of claim 3, wherein the second query request is filtered according to whether content has been previously acquired by a user making the request.

8. The method of claim 1, wherein the user request comprises one of:

text input;

menu selection; and

voice input.

9. The method of claim 1, wherein the first database comprises a knowledgebase.

10. The method of claim 9, wherein the knowledgebase comprises an ontology.

11. The method of claim 10, wherein the second database comprises content and services.

12. The method of claim 10, wherein the step of querying of the first database

comprises the step of:

understanding an intent of the user request.

13. The method of claim 10, wherein the step of querying of the first database

comprises the step of:

translating an intent of the user request.

14. The method of claim 10, wherein the step of querying of the first database

comprises the step of:

expanding an intent of the user request.

15. A machine readable medium containing instructions which when executed on a data processing system cause the data processing system to perform a method, the method comprising the steps of:

receiving a user request;

determining a user intent from the user request; and

searching a database according to the user intent.

16. The medium of claim 15, wherein the method further comprises the step of:

filtering a query result from the database to generate a response to the user request.

17. The medium of claim 15, wherein the user intent is determined according to an ontology.

18. A data processing system, comprising:

a user agent for receiving a user request;

a service agent for determining a query for the user request according to a knowledgebase; and

a search agent for searching a content database according to the query.

19. The data processing system of claim 18, further comprising:

a personalization agent for filtering a query result from the content database to generate a personalized response to the user request.

20. The data processing system of claim 18, wherein the knowledgebase comprises an ontology.

21. The data processing system of claim 18, further comprising:

a cleaner agent for removing expired data available to the agents.

22. The data processing system of claim 18, further comprising:

a recruiter agent for locating the user agent, the service agent, the search agent, the cleaner, and the personalization agent, and for forwarding a plurality of user requests among the user agent, the service agent, the search agent, the cleaner agent, and the personalization agent.
