The interpretation of tense

Xem 1-4 trên 4 kết quả The interpretation of tense
  • This paper gives an account of the role tense plays in the listener's reconstruction of the events and situations a speaker has chosen to describe. Several new ideas are presented: (a) that tense is better viewed by analogy with definite NPs than with pronouns; (b) that a narrative has a temporal focus that grounds the context-dependency of tense; and (c) that focus management heuristics can be used to track the movement of temporal focus. 1

  • This paper proposes a set of representations for tenses and a set of constraints on how they can be combined in adjunct clauses. The semantics we propose explains the possible meanings of tenses in a variety of sentential contexts. It also supports an elegant constraint on tense combination in adjunct clauses. These semantic representations provide insights into the interpretations of tenses, and the constraints provide a source of syntactic disambiguation that has not previously been demonstrated.

  • 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 time (when a sentence contains perfect aspect) and the progressive or during time. A method for providing temporal interpretation for nontensed elements in the sentence is also described.

  • Verbal and compositional lexical aspect provide the underlying temporal structure of events. Knowledge of lexical aspect, e.g., (a)telicity, is therefore required for interpreting event sequences in discourse (Dowty, 1986; Moens and Steedman, 1988; Passoneau, 1988), interfacing to temporal databases (Androutsopoulos, 1996), processing temporal modifiers (Antonisse, 1994), describing allowable alternations and their semantic effects (Resnik, 1996; Tenny, 1994), and selecting tense and lexical items for natural language generation ((Dorr and Olsen, 1996; Klavans and Chodorow, 1992), cf.
