We examine the problem of generating definite noun phrases that are appropriate referring expressions; that is, noun phrases that (a) successfully identify the intended referent to the hearer whilst (b) not conveying to him or her any false conversational implicatures (Grice, 1975). We review several possible computational interpretations of the conversational implicature maxims, with different computational costs, and argue that the simplest may be the best, because it seems to be closest to what human speakers do. We describe our recommended algorithm in detail, along with a specification of the resources a host system must provide in order to make use of the algorithm, and an implementation used in the natural language generation component of the IDAS system. 相似文献

The result of a meta-analysis is conventionally pictured in the forest plot as a diamond, whose length is the 95% confidence interval (CI) for the summary measure of interest. The Diamond Ratio (DR) is the ratio of the length of the diamond given by a random effects meta-analysis to that given by a fixed effect meta-analysis. The DR is a simple visual indicator of the amount of change caused by moving from a fixed-effect to a random-effects meta-analysis. Increasing values of DR greater than 1.0 indicate increasing heterogeneity relative to the effect variances. We investigate the properties of the DR, and its relationship to four conventional but more complex measures of heterogeneity. We propose for the first time a CI on the DR, and show that it performs well in terms of coverage. We provide example code to calculate the DR and its CI, and to show these in a forest plot. We conclude that the DR is a useful indicator that can assist students and researchers to understand heterogeneity, and to appreciate its extent in particular cases. 相似文献

The possible-worlds semantics for modality says that a sentence is possibly true if it is true in some possible world. Given
classical prepositional logic, one can easily prove that every consistent set of propositions can be embedded in a ‘maximal
consistent set’, which in a sense represents a possible world. However the construction depends on the fact that standard
modal logics are finitary, and it seems false that an infinite collection of sets of sentences each finite subset of which
is intuitively ‘possible’ in natural language has the property that the whole set is possible. The argument of the paper is
that the principles needed to shew that natural language possibility sentences involve quantification over worlds are analogous
to those used in infinitary modal logic. 相似文献

This paper explores how we can make our own mythological version of ‘Jung’ say whatever we want. Excessive veneration gets in the way of his theories being allowed to stand on their own. Understanding ‘Jung’ as a mythologem provides a way out of this intoxication with identification by letting us recollect and re‐connect to the Collective Unconscious. 相似文献

Bias in cross-sectional analyses of longitudinal mediation 总被引:2,自引:0,他引:2
Most empirical tests of mediation utilize cross-sectional data despite the fact that mediation consists of causal processes that unfold over time. The authors considered the possibility that longitudinal mediation might occur under either of two different models of change: (a) an autoregressive model or (b) a random effects model. For both models, the authors demonstrated that cross-sectional approaches to mediation typically generate substantially biased estimates of longitudinal parameters even under the ideal conditions when mediation is complete. In longitudinal models where variable M completely mediates the effect of X on Y, cross-sectional estimates of the direct effect of X on Y, the indirect effect of X on Y through M, and the proportion of the total effect mediated by M are often highly misleading. 相似文献

A comparison of mean scores on the Beck Depression Inventory and State-Trait Anger Expression Inventory scales revealed that women scored significantly higher than men on depression, whereas there were no significant differences on any of the 6 anger scales. Separate multiple regression analyses revealed that there were statistically significant relationships between the linear combination of anger scales and depression for both groups. A comparison of zero-order correlations of depression with the anger scales revealed that Anger-In correlated significantly more highly with depression among women than men. Finally Anger-In correlated significantly with 4 of the 5 other anger scales for women, but only with one for men. 相似文献

Patterns of impaired verbal,spatial, and object working memory after thalamic lesions 总被引:2,自引:0,他引:2
Working memory processes in six individuals with isolated thalamic lesions were assessed. Participants were given a verbal, spatial, and object n-back task, each at three levels of task load (1-back, 2-back, and 3-back). Relative to a control group, the patients were impaired on the verbal and spatial n-back tasks, and possibly on the object n-back task as well. None of the patients showed impaired short-term memory as measured by digit span. Group differences on trials measuring matching, sequencing, and inhibitory abilities were consistent with other reports suggesting that thalamic lesions may impair the operation of executive processes. 相似文献
