## Abstract

The subject-matter described herein relates to a computer-implemented method of enabling interoperability between a first knowledge base and a second knowledge base. Each knowledge base is graphically represented and includes a plurality of nodes each defining a concept and a plurality of relations linking the plurality of nodes. The first knowledge base and the second knowledge base are encoded using different coding standards. The method comprises: identifying an entity from the plurality of entities in the second knowledge base; obtaining a mapping between the identified entity from the second knowledge base and a matching entity from the first knowledge base; and creating and storing a link between the identified entity from the second knowledge base and the matching entity from the first knowledge base.

## Claims

### Claim 1

A computer-implemented method of enabling interoperability between a first knowledge base and a second knowledge base,
wherein each knowledge base is graphically represented and includes a plurality of nodes each defining a concept and a plurality of relations linking the plurality of nodes,
wherein the first knowledge base and the second knowledge base are encoded using different coding standards, the method comprising:
identifying a first node in the second knowledge base;
identifying a first node in the first knowledge base that partially matches the first node in the second knowledge base, wherein identifying a partial match comprises identifying a key word of the first node in the first knowledge base within a key word of the first node in the second knowledge base;
identifying a second node in the first knowledge base that partially matches the first node in the second knowledge base;
adding a second node to the second knowledge base that matches the first node from the first knowledge base, and a third node to the second knowledge base that matches the second node from the first knowledge base;
generating and storing a link between the second node from the second knowledge base and the first node from the first knowledge base, and a link between the third node from the second knowledge base and the second node from the first knowledge base; and
generating and storing a relation between the first node from the second knowledge base and the second node from the second knowledge base, and between the first node from the second knowledge base and the third node from the second knowledge base, wherein:
the nodes in the first and second knowledge bases each include a label,
identifying the first node from the first knowledge base includes searching the first knowledge base for one or more labels having a key word of one or more key words matching a key word of one or more key words of a label of the first node from the second knowledge base,
identifying the second node in the first knowledge base includes searching the first knowledge base for one or more labels having a key word of one or more key words matching a key word of one or more key words of a label of the first node from the second knowledge base,
adding the second node to the second knowledge base comprises adding the second node to the second knowledge base to include a label having an exact linguistic match to the label of the first node from the first knowledge base, and
adding the third node to the second knowledge base comprises adding the third node to the second knowledge base to include a label having an exact linguistic match to the label of the second node from the first knowledge base.

### Claim 2 (depends on 1)

The computer-implemented method of claim 1 wherein searching includes a key word search.

### Claim 3 (depends on 1)

The computer-implemented method of claim 1, further comprising sending the link to a user for verification.

### Claim 4 (depends on 1)

A non-transitory computer-readable medium including instructions stored thereon that, when executed by a processor, cause the processor to perform the method of claim 1.

### Claim 5

A computer-implemented method of enabling interoperability between a first knowledge base and a second knowledge base,
wherein each knowledge base is graphically represented and includes a plurality of nodes each defining a concept and a plurality of relations linking the plurality of nodes,
wherein the first knowledge base and the second knowledge base are encoded using different coding standards, the method comprising:
identifying a first node in the first knowledge base;
identifying that no node in the second knowledge base matches the first node in the first knowledge base;
identifying a second node in the first knowledge base, the second node from the first knowledge base taxonomically linked to the first node from the first knowledge base, wherein the second node in the first knowledge base matches a first node in the second knowledge base;
adding a second node to the second knowledge base matching the first node from the first knowledge base;
adding a relation between the first and second nodes from the second knowledge base; and
generating and storing a link between the second node from the second knowledge base and the first node from the first knowledge base.

### Claim 6 (depends on 5)

The computer-implemented method of claim 5, wherein the nodes in the first and second knowledge bases include a label, and wherein identifying that no node from the second knowledge base matches the first node from the first knowledge base includes performing a search for a label that matches the first node from the first knowledge base, and returning no matches.

### Claim 7 (depends on 5)

The computer-implemented method of claim 5, further comprising sending the link to a user for verification.

### Claim 8 (depends on 5)

A non-transitory computer-readable medium including instructions stored thereon that, when executed by a processor, cause the processor to perform the method of claim 5.
