Conventional Web search engines return long lists of ranked documents that users are forced to sift through to find relevant documents. The notoriously low precision of Web search engines coupled with the ranked list presentation make it hard for users to find the information they are looking for. One of the fundamental issues of information retrieval is searching for compromises between precis...

Although it is well documented that children undergo a productive vocabulary spurt late in the second year, it is unclear whether this development is accompanied by equally significant advances in receptive word processing. In the present study, we tested an electrophysiological procedure for assessing receptive word learning in young children, and the impact of productive vocabulary size for p...

conclusion this study shows no significant improvement in the cancer detection rate by double reading; however, a lower recall rate could be a more helpful consequence. results readers had consensus on bi-rads categories in 459 breasts (71%), but diverse categories were used for 183 breasts (29%), including 132 significant and 51 non-significant discrepancies. according to weighted kappa test, ...

It is well established that extensive reading promotes the incidental learning of L1 and L2 receptive vocabulary; however, little is known about its effectiveness on productive gains in vocabulary knowledge. This paper investigates the extent to which extensive reading combined with writing tasks promotes productive vocabulary growth of Japanese university students. To examine changes in vocabu...

We evaluated a simple computational model of productive vocabulary acquisition, applied to simulating two case studies of 7-year-old children with developmental word-finding difficulties across four core behavioural tasks. Developmental models were created, which captured the deficits of each child. In order to predict the effects of intervention, we exposed the computational models to simulate...

although filling the gap in reading comprehension gained momentum with the rise of the top-down approach, vygotsky’ concept of scaffolding and the dual code  theory provided a strong support for the use of paratext to enhance comprehension. scaffolding is dependent on other-regulation, one type of which is object-regulation. from this vantage-point, various types of paratext can function as sou...

To facilitate the use of syntactic information in the study of child language acquisition, a coding scheme for Grammatical Relations (GRs) in transcripts of parent-child dialogs has been proposed by Sagae, MacWhinney and Lavie (2004). We discuss the use of current NLP techniques to produce the GRs in this annotation scheme. By using a statistical parser (Charniak, 2000) and memorybased learning...

background: the comprehension processes are often inferred or explored indirectly through the assessment of the performance of the students on certain tasks. comprehension is typically measured by the techniques in which the test-taker reads a short text and then selects the correct answers in multiple choice questions, true/false and yes/no tasks or matching activities. purpose: a new approach...
