metadata ontology definition

However, there was also a case of disagreement, in that for the data element ‘Estimated Blood Loss’ in an Operation Note from the HL7 template, one nurse chose Procedure|Surgery and the other chose Finding|Surgery|Problem. PubMed Central  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. Grinnon ST, Miller K, Marler JR, Lu Y, Stout A, Odenkirchen J, Kunitz S. National Institute of Neurological Disorders and Stroke common data element project - approach and methods. Each CMDO concept has properties to show how it can cover the same or similar meanings for discovering semantic correspondences. Links considered as independent to contents in hypermedia are the most common vehicle for this kind of metadata. Metadata

The Ontology Metadata Sets depicted in the LDM diagram (patent drawing 14) are an isomorphic representation of an RDF/OWL metamodel, but for reverse-engineering we only populate the common subset. The ontology is not the data itself, but rather the system that defines the columns and tables ... definitions. For example, Result of Physical Examination has Breast as a child term. Again CHMR is a metadata registry that does not contain any of patients’ real data but list of descriptions and definitions of common data elements (CDEs) conforming the ISO/IEC 11179 standard for metadata description and registry. The CDE consisted of two parts: a data element concept (DEC) for the meaning of data, and the value domain (VD). Springer Nature. 1 W3C definition: An ontology defines the terms used to describe and represent an area of knowledge. Thus, when constructing an MDR or registering designed CDEs into an MDR, it is also necessary to select or design the contents of the CS using controlled vocabularies [20, 21]. Formal recording of plans in unambiguous way for informatic systems –a possibility to exchange plans between different systems 2. Healthc Inform Res. However, a complex clinical concept is often too sophisticated to be comprehensively encoded in a uniform manner, resulting in postcoordination ambiguities with many different encodings that in turn prohibit semantic interoperability. The most frequently used CMDO concepts for CMDO-matched CDEs in the 6 HL7 templates and 25 clinical documents were from the Description (n = 34) and Finding (n = 316) classes, respectively. CMDO definitions that were not obtained from UMLS either did not include brackets or their source information was represented using an indicator such as Wiki or WebMD [29]. AMIA Annu Symp Proc. Common data elements in epilepsy research: development and implementation of the NINDS epilepsy CDE project. CMDO provides precise and comprehensive semantic annotations in terms of UMLS, in that each CMDO concept has properties including synonyms and definitions that are mapped to the UMLS CUI, adopting UMLS preferred terms considering CMDO as a part of UMLS in the clinical domain to classify CDEs. A multi-technique approach to bridge electronic case report form design and data standard adoption. Kim JH. PubMed  © 2020 BioMed Central Ltd unless otherwise stated. 2014;2014:55–9. 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. And the metadata are the descriptors of the rows and the columns. Often, it is favorable to organize metadata into ontologies. To facilitate access to CMDO, we developed the CMDO Browser that provides the CMDO ID, preferred terms, and related properties such as synonyms, definitions, the parent term, and the UMLS CUI (Fig. The right panel displays the number of the CDEs tagged with the searched CMDO terms along with the list of CDEs containing the CDE name, CDE definition, and list of clinical documents containing the CDEs. Hye Hyeon Kim and Yu Rang Park contributed equally to this work. Cite as. It is the most-important source of information for clinical decision-making, communicating between healthcare providers, and addressing legal issues. We also found that the 25 clinical documents contained more-specific CDEs than the 6 HL7 templates, since 3 times as many CMDO terminal concepts were used for mapping the CDEs in the clinical documents. J Am Med Inform Assoc. Saver JL, Warach S, Janis S, et al. classes with no definition: a list of classes that have no value for the definition property.

We have had no chance of using patients’ private and/or personal information at all in writing the manuscript. We provide CMDO ID with a URL hyperlink to the corresponding CDEs in the CHMR, of which CMDO is one of the CSs. Ontologie im Wörterbuch: Bedeutung, Definition, Synonyme, Übersetzung, Herkunft, Rechtschreibung, Beispiele, Silbentrennung, Aussprache. 2013;4(1):89–99. H.H.K and J.H.K designed the study, and wrote the paper. A clinical document is a record of a patient’s medical history and care. famous definition of ontology is by Studer et al: “ontology is an explicit specification of conceptualization”. 2014. https://doi.org/10.4258/hir.2014.20.2.145. 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. Search functions for CMDO concepts can be made by entering terms in the ‘Jump to:’ box, which also has an autocomplete function. For this purpose ISO/IEC 11179 provides a classification scheme (CS) structure for the conceptual classification and identification of data elements. Table S3. 2013. https://doi.org/10.1016/j.jbi.2013.05.009. AMIA Jt Summits Transl Sci Proc. CMDO provides 459 synonyms for 139 (74.0%) CMDO concepts, and 256 definitions for 188 (100%) CMDO concepts. For ontologies in OBO and RRF formats, the property for definition is part of the language. Healthc Inform Res. • Ontologies include computer-usable definitions of basic concepts in the domain and the relationships among them – They encode domain knowledge (modular) – Knowledge that spans domains (composable) – Make knowledge available (reusable) Source: “What is An Ontology” Leo Obrst / Ontolog / 2006.01.12. ppy/Boostrapping-From-Metadata-to-Ontology--PeterYim_20070719/Jul-2007 6 … Full names of definition sources. 06/2018. Secondly, the authors themselves have developed and been in charge of operating the CHMR. It should be noted that while CMDO appears to be a feasible ontology for annotating CDEs in clinical documents, but it has the limitation of an insufficient concept coverage due to its contents and granularity; our evaluation revealed that 5% of the CMDO items are either too broad or too specific. BMC Medical Informatics and Decision Making https://doi.org/10.1136/amiajnl-2011-000739. This study has demonstrated that a clinical-content-based ontology can be used to identify standardized CDEs. The sharing, understanding, and integration of data from multiple different domains can be facilitated by standardization. By using this website, you agree to our PubMed  We call this a ‘middle-out’ approach because CDEs are pragmatically defined at a highly practical level for immediate real-world use, and then we systematically link them ‘up’ to the ontology classifications and ‘down’ to the standard controlled vocabularies. AMIA Annu Symp Proc. Methods Inf Med. http://bioportal.bioontology.org/ontologies/CMDO/. 2006. https://doi.org/10.1197/jamia.M1888. Healthc Inform Res. Clinical data from multiple sites need to be effectively integrated and compared in order to improve patient care and clinical research. Article  CMDO is an ontology and classification scheme for CDEs used in clinical documents. However, this was unsuccessful since the available ontologies were either too complicated and had a high complexity (e.g., UMLS) or were not appropriate (e.g., DO); we therefore constructed CMDO. We assigned an is-a relationship between CMDO concepts by applying the following process: Terms that appeared to be in a subordinates–superiors relationship were determined to be in an is-a relationship involving two medical doctors and two medical informatics researchers. PubMed Central  A CS has been provided for clinical documents, and document names have been standardized. The two nurses who performed the evaluation were certified medical record administrators who had an average of 5 years of work experience. The CMDO annotation process was performed by two independent nurses while considering the most-granular terms in CMDO (where this was possible). We allowed all cases of agreement or disagreement among these two annotators as following examples. The HL7/LOINC Document Ontology (DO) was developed to provide a standard representation of the attributes of clinical documents using a multiaxis structure and to standardize the names of clinical documents as an essential first step toward the optimal use, management, and exchange of documents both within and between institutions [33, 34]. Park YR, Yoon YJ, Jang TH, Seo HJ, Kim JH. None of the authors has conflicts of interest with other persons or organizations that could inappropriately influence their work. 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. The common data elements for cancer research: remarks on functions and structure. 2011;18:341–6. Data standards in clinical research: gaps, overlaps, challenges and future directions. Our construction, implementation and use of the ontology also revealed two further limitations. J Biomed Inform. All authors discussed the results and commented on the manuscript at all stages. PubMed  Detailed labels derived from one ontology not only connect everything but are critical to creating the best shortlists. Clinico-histopathological metadata registry. Health avatar: An informatics platform for personal and private big data. In this chapter, we discussed issues related to the management of metadata from the perspective of different application scenarios. CDEs are designed at a pragmatic or ‘middle’ level and then ‘out’ to the higher ontologies and the lower vocabularies in a systematic way. An ontology-based search approach can be considered as one example of a semantically enhanced information retrieval method. It seems that the CDEs in the 25 real-world clinical documents contained more observational concepts than the CDEs for the exemplar items in the 6 HL7 templates. Also, an approach for re-use of terms in pre-existing domain specific ontologies, as the vocabulary for constructing intensional metadata expressions, was discussed. statement and The ISO/IEC 11179 norm for metadata registries: does it cover healthcare standards in empirical research? Part of Springer Nature. The numbers of child terms are indicated in parentheses next to the CMDO concepts. Two administrators of medical records separately validated the two CMDO annotation sets. 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]. There are multiple benefits in using CDEs based on the ISO/IEC 11179 standard, including (1) effective and rapid data collection that reduces the burden on investigators and thereby facilitates their participation in clinical research, (2) improved data sharing and data aggregation due to employing common forms and standard definitions, and (3) higher data quality by providing unified data and their descriptions [9, 10]. 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. Ontologies have multiple advantages over other types of metadata organization. The CMDO Browser and CMDO-enabled CDE Browser make it easy to search, share, and reuse CDEs, and also effectively integrate and manage CDEs from different studies and clinical documents.

This process is experimental and the keywords may be updated as the learning algorithm improves. 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. Code review; Project management; Integrations; Actions; Packages; Security Nucleic Acids Res. Not affiliated UMLS has Concept Unique Identifier (CUI), and terms with the same CUI can be grouped together since they are semantically equivalent [28]. Healthc Inform Res. 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. Tennison J, O'Hara K, Shadbolt N. APECKS: using and evaluating a tool for ontology construction with internal and external KA support. ), based on their common class (types, properties, interrelationships, etc. Table 1 lists the statistics of CMDO concepts for each level under the first-level classes. A federated semantic metadata registry framework for enabling interoperability across clinical research and care domains. These concepts were reviewed and selected by two medical doctors and two medical informatics researchers. We also implemented ISO/IEC 11179 based on a metadata registry called the Clinico-Histopathological Metadata Registry (CHMR), which contains more than 20,000 highly curated CDEs [18, 19]. This approach resulted in 27,109 CDEs being extracted from 663 SNUH clinical documents. This service is more advanced with JavaScript available, Information Brokering Across Heterogeneous Digital Data Ontology is the study and description of reality, or what can be said to exist, and an attempt to categorize existing things and their relationship to one another. In computer science and information science, an ontology encompasses a representation, formal naming and definition of the categories, properties and relations between the concepts, data and entities that substantiate one, many, or all domains of discourse. J Am Med Inform Assoc. We found that CMDO concepts in the Finding class exhibited the highest CMDO mapping rate for CDEs in clinical documents. Table S1. We evaluated the utility of the developed CMDO using 1 personal health record (PHR) specification [CCR Plus (CCR+)] [22, 24], 6 HL7 templates [25], and 25 common clinical documents from 5 teaching hospitals in South Korea [26]. The mandatory items for CMDO are the preferred terms and CMDO ID. Clinical documents can be automatically classified and automatically managed based on the similarities between the sets of CDEs that they contain. ), and thus formalising a full or a subset of a domain. Ku HS, Kim S, Kim H, Chung HJ, Park YR, Kim JH. We also found definitions that were flagged in the definition (DEF) column of the MRDEF table. PubMed  We applied high-level integrative modeling of entire clinical documents from real-world practice to create the Clinical MetaData Ontology (CMDO) for the appropriate classification and integration of CDEs that are in practical use in current clinical documents. In form type, HL7 and CDA are represented 6 HL7 templates and 25 clinical documents from 5 teaching hospitals, respectively. CMDO has been implemented in OWL 2 using WebProtégé (version 4.0.0) [30], since this automatically checks the semantic consistency of the data to be entered, which can further improve its scalability. We created two CMDO properties (synonyms and definitions) for each CMDO concept by referencing the UMLS Metathesaurus and Wikipedia. K.H.L and Y.S.S were reviewed the first version of our ontology and revised it as the clinical point of view. Google Scholar. In this hierarchical structure, Breast refers to a result from a physical examination of the breast, and not to the anatomical structure of the breast. 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. 2015;2015:1083–92. The most-popular headings extracted from the clinical documents were assigned to CMDO concepts. 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. Sharing behavioral data through a grid infrastructure using data standards. Clinical MetaData ontology: a simple classification scheme for data elements of clinical data based on semantics. With today's powerful computers and wide data highways, the secret to digital data management is simple. CMDO is formally structured as a hierarchical tree structure, with a root value and subtrees of child nodes with a parent node. 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. Loring DW, Lowenstein DH, Barbaro NM, et al. It is therefore necessary to not only classify clinical documents themselves but also classify the CDEs contained within them in order to comprehensively understand and manage such documents. Google Scholar. First, when constructing CMDO we did not consider other methods and compare them with the GFO method, instead only considering the GFO since we considered it an appropriate method for conceptualizing ontologies. According to the standard, metadata has such things as ‘the minimum value of patient’s age is set to be zero’, ‘the gender of a patient has a permissible value of ‘M’ for male, ‘F’ for female, etc. Accessed 6 Mar 2019. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. Establishing semantic interoperability in the course of clinical document exchange using international standard for metadata registry. PubMed Central  Article  For example, to formalize the domain family, we can define the relationships husband wife, mother daughter, brother sister, and so on. 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. 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.

Quality evaluation of value sets from cancer study common data elements using the UMLS semantic groups. Table 2 indicates that 81.3, 96.0, and 100% of the CMDO concepts were rated as being adequately annotated for the 6 HL7 templates, 25 clinical documents, and the CCR+ specification, respectively. Every piece of evidence and background data related to the care can also be documented. All of the CDEs extracted from 6 HL7 templates, 25 clinical documents of 5 teaching hospitals, and 1 personal health record specification were successfully annotated by 41 (21.9%), 89 (47.6%), and 13 (7.0%) of the CMDO concepts, respectively. Discussion. Possibility to search areas of given criteria in local, regional or national scale through web service 3. Chen ES, Melton GB, Engelstad ME, Sarkar IN. Ontology Metadata Sets. In particular, we selected clinical documents from Seoul National University Hospital (SNUH) related to CDEs from among all of the CDEs in the CHMR in order to query and examine DECs. 2012. https://doi.org/10.1136/amiajnl-2011-000739. These 5 documents from SNUH and 663 clinical documents mentioned in the Methods section were mutually exclusive. Jeong S, Kim HH, Park YR, Kim JH. The total number of CMDO concepts is 189. The root term of CMDO is Clinical metadata, which has four first-level classes. We reviewed the existing upper level ontologies in an attempt to identify an appropriate one for classifying CDEs in clinical documents. This process involving procedures, observations, and testing is repeated until the end of treatment. In: Poli R, Healy M, Kameas A, editors. Metadata is a structured, coded data that describes the characteristics of media objects that facilitates the identification, detection, evaluation and management of these objects. Ontologies provide formal names to real world objects in a specific domain. To achieve semantic interoperability, these models utilize connected terms from various standard terminologies such as Unified Medical Language System (UMLS), SNOMED-CT, and LOINC. 2012. https://doi.org/10.5124/jkma.2012.55.8.729. The concepts of CMDO developed during the current study are available http://www.snubi.org/software/CMDO/, and http://bioportal.bioontology.org/ontologies/CMDO/. 2006:1056. Ontologies also provide descriptive properties of those objects and their relationships. For OWL ontologies, the authors specify this property as part of the ontology metadata (the default is skos:definition). AMIA Annu Symp Proc. J Biomed Inform.

While the leading search engines maintain their own sets of synonyms, they may not be as complete as those that can be provided by a specialized publisher. Manage cookies/Do not sell my data we use in the preference centre. For example, an admission note and discharge summary may share many CDEs such as the chief complaint, present illness, and past history, making them structurally similar but with very different administrative roles. In form type, HL7 and CDA are represented 6 HL7 templates and 25 clinical documents from 5 teaching hospitals, respectively. Barton C, Kallem C, Van Dyke P, Mon D, Richesson R. Demonstrating "collect once, use many"--assimilating public health secondary data use requirements into an existing domain analysis model. 2002;56:375–422. The HL7 Reference Information Model (RIM) and EN 13606 standards are representative data models in the healthcare domain, which include generic reference models of concepts and relationships (e.g., CEN/ISO 13606, openEHR Reference Model, and HL7 RIM) and more-detailed models (e.g., openEHR Archetypes/Templates and HL7 Detailed Clinical Model) [2, 3]. List of clinical documents used in building and evaluating CMDO. 2017. https://doi.org/10.1002/lrh2.10014. Park YR, Kim H, An EY, et al. For CMDO concepts that were not assigned to a UMLS CUI, we either used Wikipedia or manually described synonyms and definitions used by expert medical doctors. However, a major problem of this top-down ontology-construction approach is that it takes an unacceptably long time for users to adopt and use them under all possible situations that are encountered in healthcare [4]. Semantic metadata can be used to increase traffic from search engines as such metadata can provide search engines with more information about the content being searched. Nadkarni PM, Brandt CA.

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. Taxonomy and ontology are very similar phenomena used in biology to describe and classify organisms. A classification of metadata based on information content captured was discussed, and domain specific metadata was identified as the most appropriate for information brokering. Int J Hum Comput Stud.
