9 - Extending the Range of Temporal Annotation

Summary

In Chapter 9, I introduce eXTimeML, an extended variant of ISO-TimeML, with three extensions. (i) Temporal measure expressions are annotated as part of generalized measure: e.g., 30 hours. (ii) Quantified temporal expressions are annotated as part of generalized quantification: e.g., every day. (iii) Adjectives and adverbs are annotated as modifiers of nouns and verbs, respectively: e.g., daily, never. Temporal measures and temporal quantifiers are treated as part of generalized measures and quantifiers. I then illustrate how the representation language of ABS applies to each of these extensions in eXTimeML by deriving appropriate (logical) semantic forms from the well-formed annotation structures of temporal measures, quantifiers, and modifiers. Semantic forms are then interpreted with respect to admissible models, constrained by the formal definitions of logical predicates such as twice or three thousand.
