Abstract

Embodiments of the present invention provide techniques for generating ontologies. In one embodiment, techniques are provided for automatically generating an ontology based upon input information. The input information may, for example, be in the form of XSD, XML, WSDL, or WSRP, etc. The automatically generated ontology may be encoded in OWL or other RDF-compliant language. A set of inference rules may also be automatically generated using the input information. The automatically generated ontology and the set of inference rules may be stored in a database for further processing.

Claims

1. A computer-implemented method for generating an ontology, the method comprising:

receiving, at a processing system, input information in a first format;

annotating, at the processing system, the input information to generate annotated input information, wherein;

the annotating comprises adding a first set of annotations and a second set of annotations to the input information;

the first set of annotations is comprised of relationships between a plurality of entities present in the input information; and

the second set of annotations is comprised of annotations that can be used to generate a set of explicit business rules for the purposes of a specific organization, wherein;

the input information comprises an XSD file and an XML file;

annotating the input information comprises generating an annotated XSD file and an annotated XML file;

and wherein generating the ontology comprises;

converting the annotated XSD file to an OWL schema file; and

converting the annotated XML file to an OWL instance file based upon the OWL schema file; and

generating, at the processing system, based upon the annotated input information, an ontology encoded in a second format, wherein the second format is different from the first format.

2. The method of claim 1 wherein the first format is a format encoded using one of Extensible Markup Language (XML), XML Schema Definition (XSD), Web Services Description Language (WSDL), or Web Services for Remote Portlets (WSRP).

3. The method of claim 1 wherein the second format is a format encoded using Resource Description Framework (RDF) compliant language for encoding an ontology.

4. The method of claim 3 wherein the second format uses Web Ontology Language (OWL).

5. The method of claim 1 wherein the second set of annotations comprises one or more annotations that can be used to generate one or more inference rules based on the input information.

6. The method of claim 1 wherein converting the XSD file to the OWL schema file comprises mapping various XSD elements in the annotated XSD file to corresponding OWL elements based upon a mapping table.

7. The method of claim 1 wherein the generating comprises generating a set of one or more rules based upon the annotated input information.

8. The method of claim 1 wherein the generating comprises:

generating an intermediate ontology in the second format, the intermediate ontology annotated using the second set of annotations; and

removing the second set of annotations from the intermediate ontology.

9. The method of claim 1 further comprising generating an ontology graph based upon the generated ontology.

10. A computer-readable storage medium storing a plurality of instructions for controlling a processor to generate an ontology, the plurality of instructions comprising:

instructions that cause the processor to receive input information in a first format;

instructions that cause the processor to annotate the input information to generate annotated input information, wherein;

the instructions that cause the processor to annotate the input information comprise instructions that cause the processor to add a first set of annotations and a second set of annotations to the input information;

the first set of annotations is comprised of relationships between a plurality of entities present in the input information; and

the second set of annotations is comprised of annotations that can be used to generate a set of explicit business rules for the purposes of a specific organization, wherein;

the input information comprises an XSD file and an XML file;

annotating the input information comprises generating an annotated XSD file and an annotated XML file; and

wherein the instructions that cause the processor to generate the ontology comprises;

instructions that cause the processor to convert the annotated XSD file to an OWL schema file; and

instructions that cause the processor to convert the annotated XML file to an OWL instance file based upon the OWL schema file; and

instructions that cause the processor to generate, based upon the annotated input information, an ontology encoded in a second format, wherein the second format is different from the first format.

11. The computer-readable storage medium of claim 10 wherein the first format is a format encoded using one of Extensible Markup Language (XML), XML Schema Definition (XSD), Web Services Description Language (WSDL), or Web Services for Remote Portlets (WSRP).

12. The computer-readable storage medium of claim 10 wherein the second format is a format encoded using Resource Description Framework (RDF) compliant language for encoding an ontology.

13. The computer-readable storage medium of claim 10 wherein the second set of annotations comprises one or more annotations that can be used to generate one or more inference rules based on the input information.

14. The computer-readable storage medium of claim 10 wherein the instructions that cause the processor to generate an ontology comprise instructions that cause the processor to generate a set of one or more rules based upon the annotated input information.

15. The computer-readable storage medium of claim 10 further comprising instructions that cause the processor to generate an ontology graph based upon the generated ontology.

16. A system for generating an ontology, the system comprising:

a memory configured to store the ontology; and

a processor coupled to the memory, wherein the processor is configured to;

receive input information in a first format;

annotate the input information to generate annotated input information by adding a first set of annotations and a second set of annotations to the input information;

wherein;

the first set of annotations is comprised of relationships between a plurality of entities present in the input information; and

the second set of annotations is comprised of annotations that can be used to generate a set of explicit business rules for the purposes of a specific organization, wherein;

the input information comprises an XSD file and an XML file;

annotating the input information comprises generating an annotated XSD file and an annotated XML file; and

wherein generating the ontology comprises;

converting the annotated XSD file to an OWL schema file; and

converting the annotated XML file to an OWL instance file based upon the OWL schema file;

and

generate, based upon the annotated input information, an ontology encoded in a second format, wherein the second format is different from the first format.
