This chapter considers some of the basic ideas about language and linguistic analysis that define the family of feature-based grammars. Underlying the complex constraint languages and representations that give this family its characteristic ‘look and feel’ are a number of relatively straightforward claims and hypotheses. Foremost among these is the idea that many of the distinctive properties w...

We introduce a stochastic grammatical channel model for machine translation, that synthesizes several desirable characteristics of both statistical and grammatical machine translation. As with the pure statistical translation model described by Wu (1996) (in which a bracketing transduction grammar models the channel), alternative hypotheses compete probabilistically, exhaustive search of the tr...

The main objective of this paper is to model and optimize the parallel and relatively complex FuzzyP+FuzzyI+FuzzyD (FP+FI+FD) controller for simultaneous control of the voltage and frequency of a micro-grid in the islanded mode. The FP+FI+FD controller has three parallel branches, each of which has a specific task. Finally, as its name suggests, the final output of the controller is derived fro...

In this paper we present a general purpose grammar for the deep linguistic processing of Portuguese that delivers high precision grammatical analysis and detailed meaning representations. We present the main design features and evaluation results concerning the grammar’s coverage as well as its ability to produce correct grammatical analyses.

In this study we examine the roles of semantic reference and of grammatical morphology in the learning of an artificial syntax. Subjects assigned to one of three training conditions viewed sentences from a miniature phrase structure language. In the reference field condition, subjects saw sentences which each referred to an array of geometric figures. In the morphology condition no reference fi...
