metadata ontology definition

Metadaten oder Metainformationen sind strukturierte Daten, die Informationen über Merkmale anderer Daten enthalten. 103.94.16.129. In this chapter, we discussed issues related to the management of metadata from the perspective of different application scenarios. We also found definitions that were flagged in the definition (DEF) column of the MRDEF table. Table S1. PubMed Google Scholar. Kim, H., Park, Y., Lee, K. et al. Information brokering was observed to be a central component of these applications, with special emphasis on the capture, storage, and interrogation of information content. Every piece of evidence and background data related to the care can also be documented. However, most MDRs do not fully utilize or register a CS, and some MDRs support only two or three concept items in each CS for classifying their own metadata. Ontologies are, by far, the most complex type of vocabulary. To complete the CMDO annotation process, at least two medical informatics researchers confirmed the above-four CMDO annotation sets and rated their coverage of CMDO into the following categories: adequate, too broad (i.e., first-level terms or general second-level terms), or too specific (i.e., terminal-node terms that were used infrequently). These 5 documents from SNUH and 663 clinical documents mentioned in the Methods section were mutually exclusive. Finding is the first-level class with the largest number of child terms (n = 82). It also found that some CMDO concepts were too specific for utilization as a general classification and used for only specific CDEs such as ‘Consciousness State of Patient Specify’ (and hence were rated as being too specific), which comprised 4.1, 1.3, and 0% of concepts for the 6 HL7 templates, 25 clinical documents, and the CCR+ specification, respectively. CMDO has 256 definitions that cover the 189 CMDO concepts, with 459 synonyms for 139 (74.0%) of the concepts. The left panel of the CMDO Browser displays lists of CMDO preferred terms arranged as a hierarchical tree that can be navigated by clicking the name of each term to explore CMDO concepts, with their detailed properties displayed in the right panel. Die Ontologie (im 16. The main difference between taxonomy and ontology is that taxonomy is only based on hierarchy whereas ontology is based on both hierarchy and other complex variations. Sharing behavioral data through a grid infrastructure using data standards. Unable to display preview. J Biomed Inform. As a result, the interconnectedness and interoperability of the model make it invaluable for addressing the challenges of accessing and querying data in large organizations. 2012. https://doi.org/10.1136/amiajnl-2011-000739. Xu L, Furlotte N, Lin Y, Heinrich K, Berry MW, George EO, Homayouni R. Functional cohesion of gene sets determined by latent semantic indexing of PubMed abstracts. https://cdebrowser.nci.nih.gov/cdebrowserClient/cdeBrowser.html#/search. Tennison J, O'Hara K, Shadbolt N. APECKS: using and evaluating a tool for ontology construction with internal and external KA support. List of CDEs matched to CMDO concepts from two source data. The two nurses who performed the evaluation were certified medical record administrators who had an average of 5 years of work experience. DialysisNet: application for integrating and management data sources of hemodialysis information by continuity of care record. To construct an ontology for use with clinical documents, we used metadata in clinical documents obtained from the real-world clinical setting of a tertiary hospital in South Korea. One approach is to construct a common data model, which we call a top-down approach since a top-level knowledge model agreement is applied to the underlying data models of the interoperating parties to ensure successful data exchange [1]. With today's powerful computers and wide data highways, the secret to digital data management is simple. An ontology-based search approach can be considered as one example of a semantically enhanced information retrieval method. Obrst L. Ontological architectures. J Biomed Inform. Additional file 1: Table S3 lists the CDEs that were rated as being either too broad or too specific. While Ontology seeks to describe every possible thing, ontologists in computer science tend to work in particular knowledge domains, focusing their work on smaller portions of a larger ontological whole. Dabei wird etwa eine Systematik grundlegender Typen von Entität… Most (n = 164, 87.7%) of the CMDO concepts were matched to UMLS preferred terms. Jiang G, Solbrig HR, Chute CG. Table 1 lists the statistics of CMDO concepts for each level under the first-level classes. Nadkarni PM, Brandt CA. We can expect CMDO to be useful as (1) a CS for CDEs for clinical documents and CRFs, and (2) a tool for integrating CDEs from diverse clinical documents and CRFs. Healthcare providers then perform diagnostic or therapeutic procedures based on the information provided by the patient. For example, Result of Physical Examination has Breast as a child term. We will also apply other ontology methods to CMDO to check it for semantic consistency, and consider adding more concept relationships, such as part-of relationships. This study has demonstrated that a clinical-content-based ontology can be used to identify standardized CDEs. During the process of developing hierarchical relationships, identified CMDO concepts were modified to have synonyms to reflect superordinate terms. DIGITAL ONTOLOGY. For instance, the patient may say ‘During the accident I sustained an injury to the back of my head and neck.’ No concept in UMLS corresponds to the problem ‘injury to the back of the head and neck.’ Instead, the problem concept Injury (C3263722), the direction Back (C0205095), and anatomical locations Head (C0018670) and Neck (C0027530) must be postcoordinated into an on-the-fly concept [5]. 2002;56:375–422. Establishing semantic interoperability in the course of clinical document exchange using international standard for metadata registry. Definition of Ontology. 2b). Figure 1 presents a graphical representation of the CMDO classification showing the Allergy Test from Finding as a parent concept being assigned to Allergy History derived largely from Description. CMDO web services: (a) CMDO Browser and (b) CMDO-enabled CDE Browser., (c) CMDO Download Function (OWL). So an ontology would be a formal, logic based definition of the types, their properties and their interrelationships within real objects in a particular subject domain. Our construction, implementation and use of the ontology also revealed two further limitations. For OWL ontologies, the authors specify this property as part of the ontology metadata (the default is skos:definition). Jeong S, Kim HH, Park YR, Kim JH. Park YR, Yoon YJ, Jang TH, Seo HJ, Kim JH. Auch das, was nicht mit den Sinnen erfasst werden kann, ist Thema der Ontologie. Daniel C, Ouagne D, Sadou E, Paris N, Hussain S, Jaulent MC, Kalra D. Cross border semantic interoperability for learning health systems: the EHR4CR semantic resources and services. 2012. https://doi.org/10.1161/STROKEAHA.111.634352. List of CMDO concepts and its hierarchical structure. Whetzel PL, Noy NF, Shah NH, Alexander PR, Nyulas C, Tudorache T, Musen MA. statement and Healthc Inform Res. CCR+: metadata based extended personal health record data model interoperable with the ASTM CCR standard. Given the increasing use of CDEs in many studies and real-world clinical documentation, CMDO will be a useful tool for integrating numerous CDEs from different research projects and clinical documents. 2007. https://doi.org/10.1197/jamia.M2470. J Am Med Inform Assoc. To design the vocabulary, we also propose a set of generic guiding principles and a well-established methodology which take into account real concerns of the ontology users and practitioners. This research was supported by a grant of the Korea Health Technology R&D Project through the Korea Health Industry Development Institute (KHIDI), funded by the Ministry of Health & Welfare, Republic of Korea (grant number:HI18C2386). pp 17-28 | Ontologies also provide descriptive properties of those objects and their relationships. Stud Health Technol Inform. The Ontology Definition MetaModel (ODM) is an Object Management Group (OMG) specification to make the concepts of Model-Driven Architecture applicable to the engineering of ontologies. Clinical data can be captured, stored, accessed, displayed, and transmitted in clinical practices using clinical documents, which can be designed as a complex structure that comprises a multitude of data elements. Clinical documents can be automatically classified and automatically managed based on the similarities between the sets of CDEs that they contain. https://doi.org/10.1161/STROKEAHA.111.634352, https://doi.org/10.1111/j.1528-1167.2011.03018.x, https://doi.org/10.1136/amiajnl-2013-001763, https://doi.org/10.1016/j.jbi.2013.05.009, https://doi.org/10.4258/hir.2014.20.4.295, https://doi.org/10.4258/hir.2014.20.2.145, https://doi.org/10.5124/jkma.2012.55.8.729, https://doi.org/10.1371/journal.pone.0018851, http://creativecommons.org/licenses/by/4.0/, http://creativecommons.org/publicdomain/zero/1.0/, https://doi.org/10.1186/s12911-019-0877-x, Standards, technology, machine learning, and modeling. 2013;192:618–21. Healthc Inform Res. None of the authors has conflicts of interest with other persons or organizations that could inappropriately influence their work. 2 Analysis of current ontology metadata practices 2.1. These classes are the different taxonomic ranks known … 2015;2015:1083–92. The root term of CMDO is Clinical metadata, which has four first-level classes. Cookies policy. A multi-technique approach to bridge electronic case report form design and data standard adoption. We manually extracted common concepts that were counted more than twice from the DECs while considering whether it was reasonable to subordinate them to first-level terms of CMDO, and chose them as CMDO concepts, which are the child terms of each first-level term. Links considered as independent to contents in hypermedia are the most common vehicle for this kind of metadata. Metadata for the relationship between Leia and Alderaan, such as the timespan when she lived there, can be added. Stroke. CMDO was developed using one of the appropriate methodologies for conceptual modeling, the General Formal Ontology (GFO) method [27], which is a manual iterative process comprising five steps: (1) defining the scope of CMDO by conceptualizing its first-level terms (or classes), (2) identifying CMDO concepts, (3) assigning hierarchical relationships among CMDO concepts, (4) developing CMDO properties (e.g., synonyms, preferred terms, and definitions) for each CMDO concept, and (5) evaluating the utility of CMDO. Keyword searching suffers from imprecision and ambiguity; for example, documents containing synonyms of the query keywords will not be retrieved, and homonyms cannot be properly managed. Roberts K, Rodriguez L, Shooshan SE, Demner-Fushman D. Automatic extraction and post-coordination of spatial relations in consumer language. All metadata used in our work registered in the CHMR (http://chmr2.snubi.org:8083/chmr/). Correspondence to UMLS has Concept Unique Identifier (CUI), and terms with the same CUI can be grouped together since they are semantically equivalent [28]. Google Scholar. All of the CDEs extracted from two clinical document sets (six HL7 templates and five documents from the five teaching hospitals) were manually annotated with CMDO concepts. Hence, it links Common Logic (CL), the Web Ontology Language (OWL), and the Resource Description Framework (RDF). Dordrecht: Springer; 2010. p. 27–66. PubMed  2014. https://doi.org/10.1136/amiajnl-2013-001763. Learn Health Sys. Also, an approach for re-use of terms in pre-existing domain specific ontologies, as the vocabulary for constructing intensional metadata expressions, was discussed. This process is experimental and the keywords may be updated as the learning algorithm improves.
