23、onal standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Internat

24、ional organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the ru

25、les given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at

26、 least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 24617-1 was prepared by Technical Committee ISO/

27、TC 37, Terminology and other language and content resources, Subcommittee SC 4, Language resource management. ISO 24617 consists of the following parts, under the general title Language resource management Semantic annotation framework (SemAF): Part 1: Time and events (SemAF-Time, ISO-TimeML) Part 2

28、: Dialogue acts The following parts are under preparation: Part 4: Semantic roles (SemAF-SRL) Part 5: Discourse structure (SemAF-DS) The following parts are planned: Part 3: Named entities (SemAF-NE) Part 6: Principles of semantic annotation Part 7: Spatial information (ISO-Space) Part 8: Relations

29、in Discourse (SemAF-DRel) BS ISO 24617-1:2012ISO 24617-1:2012(E) ISO 2012 All rights reserved viiIntroduction This part of ISO 24617 results from the agreement between the TimeML Working Group and the ISO Working Group, ISO/TC 37/SC 4/WG 2, Language resource management Semantic annotation, that a jo

30、int activity should take place to accommodate the two existing documents for annotating temporal information, TimeML 1.2.1 and TimeML Annotation Guidelines, into ISO international standards. This work should lead to the achievement of two objectives: modification of the two documents in conformance

31、to the ISO International Standards; verification of the annotation guidelines for a wide coverage of multilingual resources. It should be noted that this part of ISO 24617 provides normative guidelines not just for temporal information, but also for information content in various types of events in

32、English as well as other languages.

33、al language texts is an increasingly important component to the understanding of those texts. This part of ISO 24617, SemAF-Time, specifies a formalized XML-based markup language called ISO-TimeML, with a systematic way to extract and represent temporal information, as well as to facilitate the exch

34、ange of temporal information, both between operational language processing systems and between different temporal representation schemes. The use of guidelines for temporal annotation has been fully attested with examples from the TimeBank corpus, a collection of 183 documents that have been annotat

35、ed by TimeML before the current version of ISO-TimeML was formulated. NOTE Throughout this document, SemAF-Time refers to the ISO 24617-1, while ISO-TimeML refers to the annotation language specified in this document. 2 Normative references The following referenced documents are indispensable for th

36、e application 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. NOTE The first reference shows how dates and times are represented and the second provides a format for the

37、standoff representation of ISO-TimeML annotation presented here.

38、of this document, the terms and definitions in ISO 8601:2004 and the following apply. NOTE The terms and definitions provided below are provided to clarify the terminology relating to the metamodel, specification, and semantics of ISO-TimeML. Terminology derived from XML and other formal languages a

39、s well as from general temporal logics is not defined here. 3.1 ALINK linking tag that represents a phase relation between an aspectual verb (or morpheme) and a predicate denoting an event (3.5) 3.2 annotation process of adding information to segments of language data or that information itself BS I

41、 something that can be said to obtain or hold true, to happen or to occur NOTE The term “event” is used here with a very broad notion of event, which includes all kinds of actions, states, processes, etc. It is not to be confused with the more narrow notion of event as something that happens at a ce

42、rtain point in time (such as the clock striking 2, or waking up) or during a short period of time (such as laughing). 3.6 instant point in time with no interior points NOTE Time is often viewed as a straight line from minus infinity to plus infinity. In this view, time is formed by an infinite seque

43、nce of points. An instant can also be seen as an infinitesimally small interval. Cf. OWL-Time Ontology for “instant”: http:/www.w3.org/TR/owl-time/. 3.7 markable entity in general, or segment of a text in particular, that is subject to an annotation (3.2) 3.8 MLINK linking tag that represents the me

44、asurement of the duration of an event (3.5) or the measurement of the length of a (possibly discontinuous) time span 3.9 point of event instant (3.6) at which the event (3.5) mentioned in a given utterance occurs NOTE Next to a point of speech, a point of event also needs to be defined in order to i

45、nterpret tense. For example, in “Arthur smiled”, the temporal location of the point of event can be defined as being prior to the point of speech. 3.10 point of reference instant (3.6) of temporal perspective on the event (3.5) in a given utterance NOTE 1 “Arthur will have gone by tomorrow”, where t

46、he point of speech is now, the point of event is some time in the future, but before the point of reference referred to by “tomorrow”. NOTE 2 To locate certain tenses in time, a third anchor point is also required, defined as the point of reference. 3.11 point of speech time unit (3.17) at which a g

47、iven utterance occurs NOTE 1 The notion of point of speech is needed in order to interpret tense. This requires the use of anchor points in time, of which the point of speech is one (point of text, see 3.12, is another one). For example, in “Arthur smiled”, the point of speech is the time that the u

48、tterance is made. NOTE 2 For a document as a whole, this may be considered to be the same as the document creation time. BS ISO 24617-1:2012ISO 24617-1:2012(E) ISO 2012 All rights reserved 33.12 point of text instant (3.6) at which reported speech is anchored NOTE It is the point of time considered

49、in the text of the speech. So for example, when a person is telling a story, it is not enough to know the point of the speech itself (the document creation time), but the point at which the speech in the story is taking place. 3.13 representation format in which an annotation (3.2) is rendered, for instance in XML, independent of its content 3.14 SLINK linking tag that represents a subordinating relation between two events (3.5) 3.15 temporal interval period uninterrupted stretch of time, with
