Abstract

A method and system for providing instance information data of at least one instance. The method has the steps of generating a semantic representation of the instance on the basis of at least one instance data source, providing a semantic representation of a domain on the basis of at least one structured domain data source, performing an integration of the semantic instance and domain representations to provide an integrated semantic representation and deriving automatically instance information data from the provided integrated semantic representation. The method and system allow to provide efficiently instance information data of a wide range of instances with technical entities and persons, in a particular patients in different domains such as radiology or anatomy.

Claims

1. A method for providing instance information data of an instance comprising:

generating a semantic representation of said instance on the basis of at least one instance data source by transforming annotated images taken of the instance by means of at least one image detection device into the semantic representation of the instance;

classifying one or more attributes of the instance at least in part on the basis of image coordinates;

generating a semantic representation of a domain on the basis of at least one structured domain data source, including;

accessing a domain ontology;

determining a context of the semantic representation of said instance; and

generating a fragment of the accessed domain ontology, including applying an automated filtering or mining process to the accessed domain ontology to exclude portions of the domain ontology unrelated to the determined context of the semantic representation of said instance;

performing an integration of the semantic representation of the instance and the semantic representation of the domain to provide an integrated semantic representation, the integrated semantic representation comprising a knowledge integration model, wherein the knowledge integration model defines an ontological structure of the semantic representation of the domain and the semantic representation of the instance;

deriving automatically instance information data from the provided integrated semantic representation; and

providing the automatically derived instance information data as a medical decision support or an instance process control.

2. The method according to claim 1, wherein said semantic representation of said instance comprises an instance ontology.

3. The method according to claim 1, wherein said instance is an object formed by a person or by a component.

4. The method according to claim 1, further comprising:

the semantic representation of the instance includes an instance ontology; and

the semantic representation of the domain includes a domain ontology;

wherein said instance ontology and said domain ontology are stored as web ontology language files.

5. The method according to claim 1, wherein said semantic representation of said domain is provided by extracting said semantic representation of said domain from a semantic representation of a top-level domain.

6. The method according to claim 5, wherein said semantic representation of said top-level domain is formed by a semantic representation of the anatomy domain or the radiology domain.

7. The method according to claim 1, wherein the integrated semantic representation is adapted to perform at least one of:

a semantic annotation of said instance,

a decision support for classification of said instance,

an instance search or

an instance process control.

8. A system for providing instance information data of an instance comprising:

at least one database storing a semantic representation of said instance and a semantic representation of a domain; and

a processing unit programmed to;

transform annotated images taken of the instance by means of at least one image detection device into a semantic representation of the instance;

classify one or more attributes of the instance at least in part on the basis of image coordinates;

generate a semantic representation of a domain by a process including;

accessing a domain ontology;

determining a context of the semantic representation of said instance; and

generating a fragment of the accessed domain ontology, including applying an automated filtering or mining process to the accessed domain ontology to exclude portions of the domain ontology unrelated to the determined context of the semantic representation of said instance;

at least one database storing the semantic representation of said instance and the semantic representation of a domain; and

wherein the processing unit is further programmed to;

perform an integration of the semantic representation of the instance and the semantic representation of the domain to provide an integrated semantic representation, the integrated semantic representation comprising a knowledge integration model, wherein the knowledge integration model defines an ontological structure of the semantic representation of the domain and the semantic representation of the instance;

automatically deriving instance information data from the integrated semantic representation; and

providing the automatically derived instance information data as a medical decision support or an instance process control.

9. The system according to claim 8, wherein said semantic representation of said instance is an instance ontology stored in a first database and

said semantic representation of said domain is stored in a second database.

10. The system according to claim 9, wherein said instance ontology is stored as a web ontology language file in said first database and

said domain ontology is stored as a web ontology language file in said second database.

11. The system according to claim 8, wherein said processing unit is adapted to execute a reasoning engine which derives automatically the instance information data from the integrated semantic representation stored in said memory.

12. The system according to claim 8, wherein said semantic representation of said instance is generated by a transformation unit which transforms annotated images of said instance into said semantic representation of said instance.

13. The system according to claim 12, wherein said annotated images are provided by an annotation unit for annotating instance images taken of an instance.

14. The system according to claim 13, wherein said instance images are generated by means of at least one image detection device selected from the group consisting of:

a computer tomograph,

a magnet resonance imaging device,

an ultrasound detection device and

a positron emission tomograph.

15. The system according to claim 8, wherein said semantic representation of a domain comprises at least one of:

an Ann-Arbor Staging document providing a classification of lymphomas patients in terms of disease progression,

a foundation model of anatomy ontology and

a radiology lexicon ontology.
