This study explores the impact of vocabulary scheme arrangement on the quality of author-generated metadata, specifically specificity and frequency of vocabulary terms chosen from schemes to describe websites. By evaluating vocabulary assigned using hierarchical and flat schemes, and by comparing these evaluations, this study seeks to isolate the arrangement of the scheme used from other variab...
Previous research found that iconicity—the motivated correspondence between word form and meaning—contributes to expressive vocabulary acquisition. We present two new experiments with two different databases and with novel analyses to give a detailed quantification of how iconicity contributes to vocabulary acquisition across development, including both receptive understanding and production. T...
In assessments of second language (L2) writing, quality of lexis typically claims more variance than other factors, and the most readily operationalized measure of lexical quality is word frequency. This study compares two methods of automatically assessing word frequency in learner productions. The first method, a band-based method, involves lexical frequency profiling, a procedure that first ...
This paper presents an evaluation of the RWTH large vocabulary speech recognition system on the Aurora 4 noisy Wall Street Journal database. First, the influence of different root functions replacing the logarithm in the feature extraction is studied. Then quantile based histogram equalization is applied, a parametric method to increase the noise robustness by reducing the mismatch between the ...
This contribution examines the macro quantitative features of 15 lowfrequency word classes. The relationship between word frequency classes and the sizes of the frequency classes obeys Altmann’s power law, and the sizes of lowfrequency word classes increase along with the increase of text length. The relationship between text length and the sizes of low-frequency word classes also obeys Altmann...
The reasons for establishing a new Swedish core vocabulary are presented, and the steps taken in its establishment are described. Some conclusions are drawn as for the usefulness o f frequency lists in this respect The impact on the frequency lists o f the nature of the corpus is illustrated. The necessity o f introducing phrases in the core vocabulary is pointed o u t The information to be ass...
this study explored reading strategy use of tefl ma students when they read academic research articles in english. the purpose of this study was to investigate how this group of readers typically approaches reading academic research articles related to their field of study, and also what they do in reading such research articles. the aim of the present study was bilateral. first, the researcher...
despite improvement of mechanical ventilation devices for infants, lung injury still causes morbidity and mortality in many cases. to determine the effect of high frequency oscillatory ventilation (hfov) in infants with severe respiratory failure, 10 neonates were evaluated prospectively. mean gestational age of these patients was 35 weeks and alveolar-arterial oxygen gradient (a-ado2) and the ...
We describe our word-based implementation of a language identifying system for the text messages written in European languages. Speci cally, we use and compare linguistic (based on functional words) and statistic (based on the word frequency) approaches to construction of the identifying vocabularies. Our version of the statistic approach copes with the di erences in degrees of word overlap amo...
