The purpose of this study was to investigate the effects of variations in text density levels and the cognitive style of field dependence on learning from a CBI tutorial, based on the dependent measures of achievement, reading comprehension, and reading rate, and of lesson completion time. Eighty college undergraduate students were randomly assigned to text density levels, after being assigned ...

With regard to the relationship between the use of modality and readability levels oftexts, 2 opposing views have been raised. The first view endorses direct positiverelationship between modality and readability in the sense that the use of modalityincreases textual understandability. The second view is that the use of modality leadsto an increase in the number of words, resulting in readabilit...

Text-based geolocation classifiers often operate with a grid-based view of the world. Predicting document location of origin based on text content on a geodesic grid is computationally attractive since many standard methods for supervised document classification carry over unchanged to geolocation in the form of predicting a most probable grid cell for a document. However, the grid-based approa...

This paper explores the use of a statistical technique known as density estimation to potentially improve the results of text categorization systems which label documents by computing similarities between documents and categories. In addition to potentially improving a system's overall accuracy, density estimation converts similarity scores to probabilities. These probabilities provide con denc...

This study compared 2 main approaches to readability assessment. Thequantitative approach applied idea density based on part of speech tagging andcompared 3 sets of text types (i.e., narrative, expository, and argumentative) withrespect to their ease of reading. The qualitative approach was done throughdeveloping questionnaires measuring intermediate EFL learners’ perceptions oncontent, motivat...

In this article, we report significant findings resulting from an investigation into the correlation between adjective density, calculated as the proportion of adjectives in word tokens, and degrees of text formality as part of an attempt to examine the potential application of adjectives in automatic text classification and identification. Correlations obtained from the training corpus will be...

Several studies have shown that the amplitude of the first rahmonic peak (R1) in the cepstrum is an indicator of hoarse voice quality. The cepstrum is obtained by taking the inverse Fourier Transform of the log-magnitude spectrum. In the present study, a number of spectral analysis processing steps are implemented, including period-synchronous and periodasynchronous analysis, as well as harmoni...

We describe two systems for text simplification using typed dependency structures, one that performs lexical and syntactic simplification, and another that performs sentence compression optimised to satisfy global text constraints such as lexical density, the ratio of difficult words, and text length. We report a substantial evaluation that demonstrates the superiority of our systems, individua...
