This paper examines two problems in document-level sentiment analysis: (1) determining whether a given document is a review or not, and (2) classifying the polarity of a review as positive or negative. We first demonstrate that review identification can be performed with high accuracy using only unigrams as features. We then examine the role of four types of simple linguistic knowledge sources in a polarity classification system.
This paper proposes an analysis method for Japanese modality. In this purpose, meaning of Japanese modality is classified into four semantic categories and the role of it is formalized into five modality functions. Based on these formalizations, information and constraints to be applied to the modality analysis procedure are specified. Then by combining these investigations with case analysis, the analysis method is proposed. This analysis method has been applied to Japanese analysis for machine translation. ...
This third edition of Analytical Chemistry for Technicians is the culmination and ﬁnal product of a series
of four projects funded by the National Science Foundation’s Advanced Technological Education Program
and two supporting grants from the DuPont Company. The grant funds have enabled me to utilize an
almost limitless reservoir of human and other resources in the development and completion of this
manuscript and to vastly improve and update the previous edition. A visible example is the CD that
accompanies this book.
Power quality has become an important issue in recent times when many utilities
around the world find very difficult to meet energy demands which leads to load
shedding and power quality problems. This book on power quality written by experts
in their fields will be of great benefit to professionals, engineers and researchers. This
book comprises of 16 chapters which are arranged in two sections. Section one covers
power quality monitoring, classification, and analysis aspects.
We present results of two methods for assessing the event profile of news articles as a function of verb type. The unique contribution of this research is the focus on the role of verbs, rather than nouns. Two algorithms are presented and evaluated, one of which is shown to accurately discriminate documents by type and semantic properties, i.e. the event profile. The initial method, using WordNet (Miller et al. 1990), produced multiple cross-classification of articles, primarily due to the bushy nature of the verb tree coupled with the sense disambiguation problem. ...
We develop a general feature space for automatic classification of verbs into lexical semantic classes. Previous work was limited in scope by the need for manual selection of discriminating features, through a linguistic analysis of the target verb classes (Merlo and Stevenson, 2001). We instead analyze the classification structure at a higher level, using the possible defining characteristics of classes as the basis for our feature space.
This project measures and classifies language variation. In contrast to earlier dialectology, we seek a comprehensive characterization of (potentially gradual) differences between dialects, rather than a geographic delineation of (discrete) features of individual words or pronunciations. More general characterizations of dialect differences then become available. We measure phonetic (un)relatedness between dialects using Levenshtein distance, and classify by clustering distances but also by analysis through multidimensional scaling.
This chapter distinguish between costs that are capitalized and costs that are expensed in the period in which they are incurred; compare the financial reporting of the following classifications of intangible assets: purchased, internally developed, acquired in a business combination; explain and evaluate the effects on financial statements and ratios of capitalizing versus expensing costs in the period in which they are incurred;...

(BQ) Part 1 book "The cutaneous lymphoid proliferations - A comprehensive textbook of lymphocytic infiltrates of the skin" presents the following contents: Introduction to the classification of lymphoma; the therapy of cutaneous T cell lymphoma; molecular analysis in cutaneous lymphoid proliferation; benign lymphocytic infiltrates; reactive lymphomatoid tissue reactions mimicking cutaneous T and B cell lymphoma,...
The first edition of Food Lipids was published in 1998 and the second edition in 2002 by Marcel
Dekker, Inc. Taylor & Francis Group, LLC, acquired Marcel Dekker and the rights to publish the
third edition. We firmly believe that this book has been of interest and will help those involved in
lipid research and instruction. Many have bought the previous editions and we thank you for your
support. The need to update the information in the second edition cannot be overstated, as more data
and new technologies are constantly becoming available.
Chapter 1 presents IVUS. Intravascular ultrasound images represent a unique
tool to guide interventional coronary procedures; this technique allows to
supervise the cross-sectional locations of the vessel morphology and to provide
quantitative and qualitative information about the causes and severity of
coronary diseases. At the moment, the automatic extraction of this kind of information
is performed without taking into account the basic signal principles
that guide the process of image generation....
Human activities are affecting the global environment in myriad
ways, with numerous direct and indirect effects on ecosystems.
The climate and atmospheric composition of Earth are changing
rapidly. Humans have directly modified half of the ice-free terrestrial
surface and use 40% of terrestrial production. Our actions are
causing the sixth major extinction event in the history of life on
Earth and are radically modifying the interactions among forests,
fields, streams, and oceans.
Lipids (fats and oils) are a wide range of organic molecules that serve several functions in organisms. Lipids are essential components of our diet, highlighting their important contribution in energy, representing 9 kcal/g (or 37.7 kJ/g), and by some components relevant to the metabolism, such as essential fatty acids, fat soluble vitamins and sterols (cholesterol and phytosterols).
Independent Component Analysis (ICA) is a signal-processing method to extract independent sources given only observed data that are mixtures of the unknown sources. Recently, Blind Source Separation (BSS) by ICA has received considerable attention because of its potential signal-processing applications such as speech enhancement systems, image processing, telecommunications, medical signal processing and several data mining issues.
In Chapter 1 we present in detail a framework for fully automated brain tissue
classification. The framework consists of a sequence of fully automated state
of the art image registration (both rigid and nonrigid) and image segmentation
algorithms. Models of the spatial distribution of brain tissues are combined with
models of expected tissue intensities, including correction of MR bias fields and
estimation of partial voluming. We also demonstrate how this framework can
be applied in the presence of lesions....
A-priori market segmentation designates groups of customers who are similar in terms
of segmentation variable(s) that are known or believed in advance to be related to con-
sumption of a company’s product, for example, demographics, purchase volume or
geographic area. Segmentation variables are selected before analysis begins.
This book deals with problems which are sufficiently important to become the subject of studies.
Cancer of the stomach remains one of the most pressing medical problems. Meanwhile,
scientific and practical interest in this problem has markedly diminished during recent years.
According to some experts, this can be explained first by the decreasing incidence of gastric
cancer. But this concerns only some developed countries, where effective measures are taken
for the prevention and early diagnosis of malignant tumors.
