Transition Network Grammars for Natural Language Analysis

by W. A. Woods - COMPUTATIONAL LINGUISTICS, D.G. BOBROW, EDITOR , 1970
"... The use of augmented transition network grammars for the analysis of natural language sentences is described. Structure-building actions associated with the arcs of the grammar network allow for the reordering, restructuring, and copying of constituents necessary to produce deep-structure representa ..."
Abstract - Cited by 328 (4 self) - Add to MetaCart
-structure representations of the type normally obtained from a transformational analysis, and conditions on the arcs allow for a powerful selectivity which can rule out meaningless analyses and take advantage of semantic information to guide the parsing. The advantages of this model for natural language analysis

Some advances in transformation-based part-of-speech tagging

by Eric Brill - In Proceedings of the Twelfth National Conference on Artificial Intelligence , 1994
"... Most recent research in trainable part of speech taggers has explored stochastic tagging. While these taggers obtain high accuracy, linguistic information is captured indirectly, typically in tens of thousands of lexical and contextual probabilities. In (Brill 1992), a trainable rule-based tagger wa ..."

LUSTRE: A declarative language for programming synchronous systems

by P. Caspi, D. Pilaud, N. Halbwachs, J. A. Plaice - In 14th Symposium on Principles of Programming Languages (POPL’87). ACM , 1987
"... LUSTRE is a synchronous data-flow language for programming syetema which interact. with their environments in real-time. After an informal presentation of the language, we describe its semantics by means of structural inference rules. Moreover, we ehow how to use this semantics in order to generate ..."

efficient, sequential code, namely, a finite state automaton which represents the control of the program. Formal rules for program transformation are also presented.

HAMMER: hierarchical attribute matching mechanism for elastic registration

by Dinggang Shen, Christos Davatzikos - IEEE Trans. on Medical Imaging , 2002
"... A new approach is presented for elastic registration of medical images, and is applied to magnetic resonance images of the brain. Experimental results demonstrate remarkably high accuracy in superposition of images from different subjects, thus enabling very precise localization of morphological cha ..."

What Is Wrong with Taylor Rules? Using Judgment in Monetary Policy through Targeting Rules

by Lars E. O. Svensson - JOURNAL OF ECONOMIC LITERATURE , 1999
"... It is argued that inflation targeting is best understood as a commitment to a targeting rule rather than an instrument rule, eitherageneral targeting rule (explicit objectives for monetary policy) or a specific targeting rule (a criterion for (the forecasts of) the target variables to be fulfilled), ..."

), essentially the equality of the marginal rates of transformation and substitution between the target variables. Targeting rules allow the use of judgment and extramodel information, are more robust and easier to verify than optimal instrument rules, and they can nevertheless bring the economy close

The Watershed Transform: Definitions, Algorithms and Parallelization Strategies

by Jos B. T. M. Roerdink, Arnold Meijster , 2001
"... The watershed transform is the method of choice for image segmentation in the field of mathematical morphology. We present a critical review of several definitions of the watershed transform and the associated sequential algorithms, and discuss various issues which often cause confusion in the li ..."

Lambda Lifting: Transforming Programs to Recursive Equations

by Thomas Johnsson , 1985
"... Lambda lifting is a technique for transforming a functional program with local function definitions, possibly with free variables in the function definitions, into a program consisting only of global function (combinator) definitions which will be used as rewrite rules. Different ways of doing lambd ..."

Growing World Trade: Causes and Consequences

by Paul Krugman - Brookings Papers on Economic Activity , 1995
"... WHAT ASPECT OF the American economy has changed most in the twenty-five years since Brookings Papers on Economic Activity first be-gan appearing? If you took a poll of economic journalists, businessmen, or policy intellectuals other than professional economists, globaliza-tion-the growing integratio ..."

integration of the United States with the world econ-omy-would probably top the list. It is now conventional wisdom in many circles that the growth of world trade and investment has trans-formed the ground rules for economic policy. Admittedly, many international economists regard the popular con

The Fourier-Series Method For Inverting Transforms Of Probability Distributions

by Joseph Abate, Ward Whitt , 1991
"... This paper reviews the Fourier-series method for calculating cumulative distribution functions (cdf's) and probability mass functions (pmf's) by numerically inverting characteristic functions, Laplace transforms and generating functions. Some variants of the Fourier-series method are remar ..."

GOLD: A Parallel Real-Time Stereo Vision System for Generic Obstacle and Lane Detection

by Massimo Bertozzi, Alberto Broggi - IEEE TRANSACTIONS ON IMAGE PROCESSING , 1998
"... This paper describes the Generic Obstacle and Lane Detection system (GOLD), a stereo vision-based hardware and software architecture to be used on moving vehicles to increment road safety. Based on a full-custom massively parallel hardware, it allows to detect both generic obstacles (without constra ..."
