While automatic text summarization is an area that has received a great deal of attention in recent research, the problem of efficiency in this task has not been frequently addressed. When considering the size and quantity of documents available on the Internet and from other sources, the need for a highly efficient tool that produces usable summaries is clear. We present a linear time algorith...

1. INTRODUCTION. Many factors affect the ease or difficulty of understanding a word in a sentence, including the lexical frequency of the word, the syntactic context, the discourse context, the intonation of the sentence, and the plausibility of the situation described by the sentence thus far (see Gibson & Pearlmutter 1998 and Tanenhaus & Trueswell 1995 for summaries of relevant factors and ev...

The purpose of this study is to evaluate the validity of measuring grammatical diversity with a specifically designed Lexical Diversity Assessment Tool (LDAT). A secondary objective is to use LDAT to determine if the level of difficulty assigned to English as a Second Language (ESL) texts corresponds to increases in grammatical, lexical, and temporal diversity. Other methods of lexical diversit...

This quasi-experimental study aimed to investigate the effect of task repetition under four conditions on the three dimensions of oral production (accuracy, complexity and fluency) and grammatical knowledge gain of learners of English as a Foreign Language (EFL). 40 young learners of English as a Foreign Language in four classes were randomly assigned into one of the following groups: repetitio...

The structure of lexical entries and the status of lexical decomposition remain controversial. In the psycholinguistic literature, one aspect of this debate concerns the psychological reality of the morphological complexity difference between compound words (teacup) and single words (crescent). The present study investigates morphological decomposition in compound words using visual lexical dec...

The contributions of social processes and computational processes to early lexical development were evaluated. A re-analysis and review of previous research cast doubt on the sufficiency of social approaches to word learning. An empirical investigation of the relation of social-pragmatic and data-providing features of input to the productive vocabulary of sixty-three 2-year-old children reveale...

The present study aims at investigating the effect of different levels of lexical collocational density on EFL learners’ reading comprehension. Eighty sophomore students with different levels of proficiency studying at  Zand Institute of Higher Education in Shiraz, Iran were chosen from among eighty five learners based on their score distribution on a reduced TOEFL test constructed by Education...

Measuring reading effort is useful for practical purposes such as designing learning material and personalizing text comprehension environment. We propose a quantification of reading effort by measuring the complexity of eye-movement patterns of readers. We call the measure Scanpath Complexity. Scanpath complexity is modeled as a function of various properties of gaze fixations and saccadesthe ...
