The centering framework explains local coherence by relating local focus and the form of referring expressions. It has proven useful in monolog, but its utility for multiparty discourse has not been shown, and a variety of issues must be tackled to adapt the model for dialog. This paper reports our application of three naive models of centering theory for dialog. These results will be used as baselines for evaluating future models.
Mathematical Modeling I – preliminary is designed for undergraduate students. Two other followup
books, Mathematical Modeling II – advanced and Mathematical Modeling III – case studies in biology,
will be published. II and III will be designed for both graduate students and undergraduate students.
All the three books are independent and useful for study and application of mathematical modeling in
The aim of this work is to present some preliminary results of an investigation in course on the typology of the morphology of the native South American languages from the point of view of the formal language theory. With this object, we give two contrasting examples of descriptions of two Aboriginal languages ﬁnite verb forms morphology: Argentinean Quechua (quichua santiague˜ o) and Toba.
We present a preliminary study on unsupervised preposition sense disambiguation (PSD), comparing different models and training techniques (EM, MAP-EM with L0 norm, Bayesian inference using Gibbs sampling). To our knowledge, this is the ﬁrst attempt at unsupervised preposition sense disambiguation.
In this work I address the challenge of augmenting n-gram language models according to prior linguistic intuitions. I argue that the family of hierarchical Pitman-Yor language models is an attractive vehicle through which to address the problem, and demonstrate the approach by proposing a model for German compounds. In an empirical evaluation, the model outperforms the Kneser-Ney model in terms of perplexity, and achieves preliminary improvements in English-German translation.
For the last two decades, Vietnam has achieved great developments in economic. Our
country is in the middle of industrialization and modernization process. But side-effects of
economic developments which is greater than ever are environmental problems, especially
water pollution. At present, with the pressure of environmental pollution, river water
quality is showing signs of pollution at some degrees. For the season, it is necessary to
assessing and monitoring river water quality, then using models to simulate water quality
to propose managing strategies.
This paper discusses the task of formulating a model of linguistic performance and proposes an approach toward this goal that is oriented toward an embodiment of the model as a digital-computer program. The methodology of current linguistic theory is criticized for several of its features that render it inapplicable to a realistic model of performance, and remedies for these deficiencies are proposed.
.This product is part of the RAND Corporation technical report series. Reports may include research ﬁndings on a speciﬁc topic that is limited in scope; present discussions of the methodology employed in research; provide literature reviews, survey instruments, modeling exercises, guidelines for practitioners and research professionals, and supporting documentation; or deliver preliminary ﬁndings. All RAND reports undergo rigorous peer review to ensure that they meet high standards for research quality and objectivity....
It exploits a vector-space model developed in information retrieval research. We present a preliminary result from our computational experiment. Introduction Many machine translation systems have been developed and commercialized. When these systems are faced with unknown domains, however, their performance degrades. Although there are several reasons behind this poor performance, in this paper, we concentrate on one of the major problems, i.e., building a bilingual dictionary for transfer.
This paper describes the development of a rule-based computational model that describes how a feature-based representation of shared visual information combines with linguistic cues to enable effective reference resolution. This work explores a language-only model, a visualonly model, and an integrated model of reference resolution and applies them to a corpus of transcribed task-oriented spoken dialogues.
The purpose of this text is to provide the basis for an upper-level undergraduate
or graduate course over one or two semesters, covering basic concepts and
examples of fluid mechanics with particular applications in the natural environment.
The book is designed to meet a dual purpose, providing an advanced
fundamental background in the fluid mechanics of environmental systems and
also applying fluid mechanics principles to a variety of environmental issues.
The topics of control engineering and signal processing continue to ﬂourish and
develop. In common with general scientiﬁc investigation, new ideas, concepts
and interpretations emerge quite spontaneously and these are then discussed,
used, discarded or subsumed into the prevailing subject paradigm. Sometimes
these innovative concepts coalesce into a new sub-discipline within the broad
subject tapestry of control and signal processing. This preliminary battle be-
tween old and new usually takes place at conferences, through the Internet and
in the journals of the discipline.
Applied statistics for civil and environmental engineers has many contents: Preliminary Data Analysis, Basic Probability Concepts, Random Variables and Their Properties, Model Estimation and Testing, Methods of Regression and Multivariate Analysis, Frequency Analysis of Extreme Events, Simulation Techniques for Design, Risk and Reliability Analysis, Bayesian Decision Methods and Parameter Uncertainty.
This book is an extension of “Probability for Finance” to multi-period financial models, either in the discrete or continuous-time framework. It describes the most important stochastic processes used in finance in a pedagogical way, especially Markov chains, Brownian motion and martingales. It also shows how mathematical tools like filtrations, Itô’s lemma or Girsanov theorem should be understood in the framework of financial models. It also provides many illustrations coming from the financial literature....

P-glycoprotein at the blood-brain barrier: kinetic modeling of 11C-desmethylloperamide in mice using a 18F-FDG μPET scan to determine the input function
Lieselotte Moerman1*, Dieter De Naeyer2, Paul Boon3 and Filip De Vos1
Purpose: The objective of this study is the implementation of a kinetic model for 11C-desmethylloperamide (11CdLop) and the determination of a typical parameter for P-glycoprotein (P-gp) functionality in mice.
This book is about pricing issues in modern communications networks. Recent technology
advances, combined with the deregulation of the communication market and the
proliferation of the Internet, have created a new and highly competitive environment for
communication service providers. Both technology and economics play a major role in
this new environment. As recent events in the marketplace make clear, the success of a
communication services business is not guaranteed by new technology alone.
Today there are many services which provide information over the phone using
a prerecorded or synthesized voice. These voices are invariant in speed. Humans giving information over the telephone, however, tend to adapt the speed of their presentation to suit the needs of the listener. This paper presents a preliminary model of this adaptation. In a corpus of simulated directory assistance dialogs the operator’s speed in number-giving correlates with the speed of the user’s initial response and with the user’s speaking rate.
Chapter 1 - Introduction. This chapter sets the scene for the book by discussing in broad terms the questions of what is econometrics, and what are the ‘stylised facts’ describing financial data that researchers in this area typically try to capture in their models. It also collects together a number of preliminary issues relating to the construction of econometric models in finance.
