Information exchange between heterogeneous databases through automated identification of concept equivalence
First Claim
Patent Images
1. A system for exchanging information between a first database and a second database, the system comprising:
- a constructor for producing a first semantic network representation of the first database;
a concept matcher for identifying semantic concept equivalencies between the semantic network representation of the first database and a semantic network representation of the second database; and
a query processor using one of the identified semantic concept equivalencies to generate a request to access data from the second database.

Abstract
Described are a system and methods for exchanging information between heterogeneous databases (28,28′). A constructor (54) produces a first semantic network (58) representation of a first database (28). A concept matcher (52) identifies semantic concept equivalencies (64) between the semantic network (58) representation of the first database (28) and a second semantic network (58′) representation of the second database (28′). A query processor (66) uses one of the identified semantic concept equivalencies (64,64′) to generate a request to access data from the second database (28).

17. A method for exchanging data between databases, the method comprising:
-
generating a first semantic network representation of a first database;
receiving a second semantic network representation of a second database;
identifying semantic concept equivalencies between the first and second semantic network representations; and
producing a request to retrieve information from the second database using at least one of the identified semantic concept equivalencies. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

35. A method of exchanging data between databases, the method comprising:
-
generating a semantic network representation of a first database; and
receiving a request from a remote database system to retrieve information from the first database, the request identifying a node of the semantic network representation; and
retrieving information from the first database using a query formulated from information associated with the node of the semantic network representation. - View Dependent Claims (36, 37, 38, 39, 40, 41, 42)
