1. A method for maintaining a knowledge base and an evidence set derived from the knowledge base, the knowledge base having a relationship existing between a first object and a second object, comprising the steps of:
- specifying a request by identifying a query relationship between a first query log parameter and a second query log parameter;
modifying the knowledge base in accordance with the request and the query relationship; and
deriving the evidence set from the knowledge base.

1. A method for maintaining a knowledge base and an evidence set derived from the knowledge base, the knowledge base having a relationship existing between a first object and a second object, comprising the steps of:
-
specifying a request by identifying a query relationship between a first query log parameter and a second query log parameter;
modifying the knowledge base in accordance with the request and the query relationship; and
deriving the evidence set from the knowledge base. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 16)
storing said first query log parameter received from a user;
storing said second query log parameter; and
formulating the request in accordance with the relationship.
-
-
6. The method of claim 5, wherein the first query log parameter is a search query received from a user.
-
7. The method of claim 5, wherein the second query log parameter is an indicator of an accessed document.
-
8. The method of claim 5, wherein the second query log parameter is a source indicator.
-
9. The method of claim 5, wherein the second query log parameter is an indicator of a matching document.
-
10. The method of claim 1, further including the steps of:
-
sending the request to an administrator; and
receiving an approval from the administrator.
-
-
11. The method of claim 1, wherein the first object includes a first entity, the second object includes a second object, and the relationship includes a description logic relationship existing between the first entity and the second entity.
-
12. The method of claim 1, wherein the first object includes a first class, the second object includes a second class, and the relationship includes a rule-based relationship existing between the first class expression and the second class expression.
-
13. The method of claim 1, wherein said deriving step is subsequent to said modifying step.
-
14. The method of claim 1, wherein the knowledge base includes a class, the evidence set includes a topic and a term, said deriving step includes the step of:
-
identifying a first relationship between the class and the topic and a second relationship between the first object and the term;
ordering the topic and the term in a hierarchical structure in the evidence set.
-
-
16. The method of claim 1, further comprising the step of:
performing a search using the evidence set.
-
15. The method of 1, wherein the request includes an operation in which an operand is a term.
-
17. A method for modifying an evidence set, comprising the steps of:
-
storing a first query log parameter;
storing a second query log parameter;
identifying a relationship between the first query log parameter and the second query log parameter; and
modifying the evidence set in accordance with the relationship. - View Dependent Claims (18, 19, 20)

22. An apparatus for maintaining an evidence set and a knowledge base, the evidence set being derived from the knowledge base, the knowledge base having a first object and a second object, a relationship existing between the first object and the second object, comprising:
-
means for specifying a request including means for identifying a query relationship between a first query log parameter and a second query log parameter;
means for modifying the knowledge base in accordance with the request and the relationship; and
means for deriving the evidence set based on the knowledge base.

-
23. A medium that stores instructions adapted to be executed by a processor to perform the steps of:
-
specifying a request by identifying a query relationship between a first query log parameter and a second query log parameter;
modifying the knowledge base in accordance with the request and the relationship; and
deriving the evidence set based on the knowledge base.
