Abstract
Embodiments of an informatics platform where collected data can be normalized, integrated and mapped to a knowledge source, such as medical vocabulary systems are disclosed. One example of such a knowledge source is Unified Medical Language System (UMLS) which is a knowledge source for biomedical applications. Embodiments as depicted herein may provided a method to convert the desired information from UMLS into an ontology representation to allow for its use in conjunction with an informatics system.
Claims18
A system for creating an ontology representation, comprising:
- an informatics system comprising a processor and a non-transitory computer readable medium comprising instructions for:
- creating a Simple Knowledge Organization System (SKOS) representation of the unified medical language system (UMLS), wherein the UMLS includes a UMLS-Semantic Network (UMLS-SN) and a UMLS-Metathesaurus (UMLS-MTH) comprised of one or more source vocabularies and the SKOS representation of the UMLS includes a SKOS representation of the UMLS-SN, a SKOS representation of the UMLS-MTH and a representation of one or more relationships between the UMLS-SN and the UMLS-MTH, wherein creating the SKOS representation of UMLS comprises converting the UMLS-SN to a SKOS representation, converting the UMLS-MTH to SKOS;
- populating the SKOS representation of the UMLS-MTH with concept unique identifiers (CUI) for concepts of the UMLS-MTH, creating one or more representations of the source vocabularies comprising UMLS-MTH, populating the representations of the one or more source vocabularies for the SKOS representation of UMLS and mapping the representations of the one or more source vocabularies in the SKOS representation of ULMS to the UMLS-MTH representation to assert correspondence of concepts and wherein the populated CUIs in the representation of the UMLS-MTH are used as a mapping point between concepts of the representations of the one or more source vocabularies.
A method for creating an ontology representation, comprising:
- creating a Simple Knowledge Organization System (SKOS) representation of the unified medical language system (UMLS), wherein the UMLS includes a UMLS-Semantic Network (UMLS-SN) and a UMLS-Metathesaurus (UMLS-MTH) comprised of one or more source vocabularies and the SKOS representation of the UMLS includes a SKOS representation of the UMLS-SN, a SKOS representation of the UMLS-MTH and a representation of one or more relationships between the UMLS-SN and the UMLS-MTH, wherein creating the SKOS representation of UMLS comprises converting the UMLS-SN to a SKOS representation, converting the UMLS-MTH to SKOS;
- populating the SKOS representation of the UMLS-MTH with concept unique identifiers (CUI) for concepts of the UMLS-MTH, creating one or more representations of the source vocabularies comprising UMLS-MTH, populating the representations of the one or more source vocabularies for the SKOS representation of UMLS and mapping the representations of the one or more source vocabularies in the SKOS representation of ULMS to the UMLS-MTH representation to assert correspondence of concepts and wherein the populated CUIs in the representation of the UMLS-MTH are used as a mapping point between concepts of the representations of the one or more source vocabularies.
A non-transitory computer readable medium comprising instructions for:
- creating a Simple Knowledge Organization System (SKOS) representation of the unified medical language system (UMLS), wherein the UMLS includes a UMLS-Semantic Network (UMLS-SN) and a UMLS-Metathesaurus (UMLS-MTH) comprised of one or more source vocabularies and the SKOS representation of the UMLS includes a SKOS representation of the UMLS-SN, a SKOS representation of the UMLS-MTH and a representation of one or more relationships between the UMLS-SN and the UMLS-MTH, wherein creating the SKOS representation of UMLS comprises converting the UMLS-SN to a SKOS representation, converting the UMLS-MTH to SKOS;
- populating the SKOS representation of the UMLS-MTH with concept unique identifiers (CUI) for concepts of the UMLS-MTH, creating one or more representations of the source vocabularies comprising UMLS-MTH, populating the representations of the one or more source vocabularies for the SKOS representation of UMLS and mapping the representations of the one or more source vocabularies in the SKOS representation of ULMS to the UMLS-MTH representation to assert correspondence of concepts and wherein the populated CUls in the representation of the UMLS-MTH are used as a mapping point between concepts of the representations of the one or more source vocabularies.
