Plan-based Event Representations for the Analysis of Tense and Aspect
نویسندگان
چکیده
In this paper, a representation formalism based on actions and hierarchical plans is proposed to model the aspectual and temporal composition of sentences. Action verbs are interpreted as (possibly un-derspeciied) instances of action schemata that include a plan body; the interpretation process is carried out in an incremental way: the other linguistic elements, like tense and adverbs, are evaluated by means of rules that add constraints to event representations. Pragmatic factors related to the communicative situations are accounted for by introducing defea-sible rules for conversational implicatures that determine the telicity of a given description.

متن کاملThe Interpretation of Tense and Aspect in English
An analysis of English tense and aspect is presented that specifies temporal precedence relations within a sentence. The relevant reference points for interpretation are taken to be the initial and terminal points of events in the world, as well as two "hypothetical" times: the perfect t ime (when a sentence contains perfect aspect) and the progressive or during time. A method for providing tem...
