Two main difficulties in SVM (Support-Vector Machine) and other machine-learning based biological named entity recognition are the existence of many different spelling variants and a lack of annotated corpus for training. Attempts are made to resolve these two difficulties respectively, which turn out to be rewarding. We automatically expand the annotated corpus in a fast, efficient, and easy w...

In recent literature on persons with learning disabilities (LD), speech recognition has been discussed primarily as an assistive technology to help compensate for writing difficulties. However, prior research by the authors has suggested that in addition to helping persons to compensate for poor writing skills, speech recognition also may enhance reading and spelling; that is, what was designed...

This family-risk (FR) study examined whether the literacy skills of parents with dyslexia are predictive of the literacy skills of their offspring. We report data from 31 child-parent dyads where both had dyslexia (FR-D) and 68 dyads where the child did not have dyslexia (FR-ND). Findings supported the differences in liability of FR children with and without dyslexia: the parents of the FR-D ch...

This study examined the relationships between the cognitive processes of rapid naming and phonological processing and various literacy skills. Variables measured and used in this analysis were phonological processing, rapid naming, reading comprehension, isolated and nonsense word reading, and spelling. Data were collected from 65 second-to-fifth grade children referred for learning difficultie...

The present study explored how children's prephonological writing foretells differential learning outcomes in primary school. The authors asked Portuguese-speaking preschool children in Brazil (mean age 4 year 3 months) to spell 12 words. Monte Carlo tests were used to identify the 31 children whose writing was not based on spellings or sounds of the target words. Two and a half years later, th...

The present study explored how children’s prephonological writing foretells differential learning outcomes in primary school. We asked Portuguese-speaking preschool children in Brazil (mean age 4 1/4 years) to spell 12 words. Monte Carlo tests were used to identify the 31 children whose writing was not based on spellings or sounds of the target words. 2 1/2 years later, the children took a stan...

The current experiment investigated conflicting predictions regarding the effects of spelling-stress regularity on the lexical decision performance of skilled adult readers and adults with developmental dyslexia. In both reading groups, lexical decision responses were significantly faster and significantly more accurate when the orthographic structure of a word ending was a reliable as opposed ...

This is a case study of an adolescent who had largely overcome his early difficulty in learning to read, but continued to have severe problems with spelling. He had no visual memory impairment, and his letter-sound knowledge and phonemic awareness were at adult levels. Testing revealed that his difficulties in both reading and spelling only manifested when processing unfamiliar words. He was sl...

The purpose of this paper is to examine the role of home literacy, parental education and demographic factors in addition to conventional literacy skills at the beginning and end of kindergarten in predicting end of kindergarten spelling achievement. The present study involved 9 schools and 29 classrooms serving an economically and ethnically diverse population (n = 288). Students spelled three...
