EN 12381:2005 (E) 4 Introduction Time is an important variable in healthcare, and standards are

23、 needed about how to represent information with explicit references to time. This document is a first contribution to this harmonization process, focusing on “representation” and “explicit reference”. Indeed, a system for Time-Standards must have as a minimum requirement the capacity to order tempor

24、al facts (situations, events, episodes) in three major ways, independent of any specific ontology of time itself: by relating situations to a calendar; by relating situations to “reference” situations; by relating events together in “before- and after-” chains. The main reason for this threefold org

25、anization is that our everyday temporal discourse contains a variety of expressions that only with a certain artificiality can be regimented into a uniform style of analysis. The purpose of this document is to enhance, in a perspective of machine-machine and man-machine communication, the generation

26、 of statements that are guaranteed to be understood unambiguously with respect to the time-related expressions that are embedded within them. The purpose of this document is not to develop a full-blown temporal logic, but a standardized way of representing time-related expressions, such that all kin

27、ds of questions about the temporal organization of situations can be answered on the basis of the information available. Nor is it the intention of the framework presented here to provide a means to interpret the information in its original format. Interpretation of the source information is the tas

28、k of the provider of information itself. The framework presented in this document allows information providers to express their time-related information in such a way that the intended meaning can be unambiguously understood by a receiver. This of course requires the use of a “restricted”, regimente

29、d model or language, allowing the disambiguation of many time-related expressions uttered in natural language. The model (language) presented in this document is restricted enough to allow such disambiguation for time-related expressions in “traditional” medical language, but is not expressive enoug

30、h to account for all time-related linguistic phenomena that can be encountered in natural language. This document provides representational tools for “explicit” time-related information. It does not allow (nor encourage) the ad hoc interpretation of implicit temporal information. In an expression su

31、ch as “diabetes since childhood”, “since childhood” is an explicit temporal reference for the diabetes, but the implicit information what “childhood” might mean (e.g. starting at the age of 2 years ?), is not addressed. However, the framework presented in this document has enough expressive power to

32、 allow a specific provider of information to state explicitly what his understanding is of “childhood”. This document describes some conformance characteristics by means of which developers of health care information systems can label specific modules of their systems as to the degree they are compl

33、iant with the document. Although the framework itself does not deal with temporal reasoning, the conformance characteristics can be used to evaluate to what level temporal reasoning is possible with the information collected in a given system. EN 12381:2005 (E) 5 1 Scope This document specifies a se

34、t of representational primitives and semantic relations required for an unambiguous representation of explicit time-related expressions in health informatics. This document does not introduce or force a specific ontology of time, nor does it force the use of a fixed representation scheme for such an

35、 ontology. Rather this document provides a set of principles for syntactic and semantic representation that allow the comparability of specific ontologies on time, and the exchange of time-related information that is expressed explicitly. This document is applicable to: 1) developers of medical info

36、rmation systems in which the need is felt to have explicit time-related concepts for internal organization (e.g. temporal data bases, temporal reasoning systems); 2) information modellers or knowledge engineers building models for the systems mentioned in (1); 3) experts involved in the development

37、of semantic standards on precise subdomains in health care where time-related information need to be covered, (e.g. in the study of Pathochronology, i.e. the discipline dealing with the time course of specific diseases); 4) developers of interchange formats for messages in which time-related informa

38、tion is embedded. This document is not intended to be used directly for: 1) representing what is true in time; 2) reasoning about time; 3) representation of metrological time (which is covered in other standards). 2 Normative references The following referenced documents are indispensable for the ap

39、plication of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 28601, Data elements and interchange formats - Information interchange - Representation of dates and times (I

40、SO 8601:1988 and its technical corrigendum 1:1991) ISO 31-1, Quantities and units Part 1: Space and time 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 situation phenomenon occurring (or having the potential to occur) at or over a time in a

41、given world context NOTE 1 situations cover phenomena which may occur in past, present or future time NOTE 2 This document applies both to the representation of actual phenomena occuring in the real world (e.g. registrations in medical records), as to the description of concepts (eg medical knowledg

42、e bases). EN 12381:2005 (E) 6 EXAMPLE “The patient suffered from pain which occurred over night”, “pain occurring over night”, 3.2 time interval portion of time of which the duration in a given context is considered to be significant and relevant 3.3 time point portion of time of which the duration

43、in a given context is considered to be insignificant or irrelevant NOTE This document does not specify any regulations on what entities should occupy time points, and what entities should occupy time intervals. Decisions of this kind are explicitly to be made by the user of this document (Chapter 5)

44、. As a consequence, temporal references such as “Friday the 13th” may refer to a time point or a time interval, depending on the context. 3.4 episode situation considered to occupy a time interval NOTE 1 Whether a situation is to be considered an episode or an event, is a decision taken by the provi

45、der of the information, based on its perception of the phenomenon in a given context. NOTE 2 It is possible to further subcategorize episodes into “states”, “culminations”, “processes”, “actions”, or other conceptual entities that can be defined using additional conceptual aspects describing particu

46、lar properties of each of the various episodes. However there is no need to do so within the scope of this document. EXAMPLE a patients stay in the hospital, the “episode of care” related to a medical problem 3.5 event situation considered to occur at a time point 3.6 predication representation of a

47、 situation in a language EXAMPLE “The removal of Mr Jones appendix on 21 July 1994, at 9 oclock in the morning.” 3.7 temporal reference component of a predication representing information related to time EXAMPLE “on 1994-07-21”, “at 9 oclock”, “on 1994-07-21 at 9 oclock” 3.8 propositional clause com

48、ponent of a predication to which temporal references implicitly or explicitly refer EXAMPLE in the expression “taking syrup three times a day for 2 weeks”, the propositional clause is “taking syrup”. To it are attached the temporal references “three times a day” and “for 2 weeks”. NOTE 1 The term pr

49、opositional clause is used here in a broader sense than in formal logic where a proposition denotes a statement on what is true in a given world. In the context of this document, propositional clauses do not impose a truth-value on the phenomena that are represented. NOTE 2 This document allows for a recursive representation of information related to time (see Informative Annex A for a formal description). In expressions such as “severe headache lasting for half an hour after each meal”, both “severe headache” and “severe headache
