Annotating "tense" in a Tense-less Language

In the context of Natural Language Processing, annotation is about recovering implicit information that is useful for natural language applications. In this paper we describe a “tense” annotation task for Chinese, a language that does not have grammatical tense, that is designed to infer the temporal location of a situation in relation to the temporal deixis, the moment of speech. If successful...

Tense like equality algebras

In this paper, first we define the notion of involutive operator on bounded involutive equality algebras and by using it, we introduce a new class of equality algebras that we called it a tense like equality algebra. Then we investigate some properties of tense like equality algebra. For two involutive bounded equality algebras and an equality homomorphism between them, we prove that the tense ...

A Tense And Aspect Calculus

This paper focuses on a theory of tense and aspect the representation of time in natural language that attempts a formal representation of the relevant lin guistic devices as implication rules in rst order logic It presents a rich ontology as far as verb aspect is concerned distinguishing between complex patterns and vagueness Examples and conclusions are drawn from the com parison between Engl...

Tense as a Nominal Category

Recent work in morphology in LFG (Nordlinger 1998, Sadler 1998, Barron 1998) has highlighted the fact that NPs in some languages inflect for the traditionally verbal categories of tense, aspect or mood (henceforth TAM). This phenomenon is extremely problematic for head-driven approaches such as HPSG, which assumes that clause-level information will be associated with clausal heads, and not with...
