Now We're Talking: Leveraging the Power of Natural Language Processing to Inform ITS Development

In the current study, we utilize natural language processing techniques to examine relations between the linguistic properties of students’ self-explanations and their reading comprehension skills. Linguistic features of students’ aggregated selfexplanations were analyzed using the Linguistic Inquiry and Word Count (LIWC) software. Results indicated that linguistic properties of self-explanatio...

Look Who’s Talking NOW! Parentese Speech, Social Context, and Language Development Across Time

In previous studies, we found that the social interactions infants experience in their everyday lives at 11- and 14-months of age affect language ability at 24 months of age. These studies investigated relationships between the speech style (i.e., parentese speech vs. standard speech) and social context [i.e., one-on-one (1:1) vs. group] of language input in infancy and later speech development...

New antiplatelet agents: are we better off now than we were with aspirin?

Yesterday's future: the gap between where we are now and where we were supposed to be.

Had my dear mentor and friend, the Canadian surgeon Pierre Grondin, been alive today he would have been surprised—or even shocked—to realize that, 45 years after he placed the tricuspid valve in the surgical arena, we heart surgeons are still debating which is the best repair technique [1]. In spite of all the known limitations of a retrospective analysis, the paper by Thomas Guenther et al. ex...

D-Theory: Talking about Talking about Trees

Linguists, including computational linguists, have always been fond of talking about trees. In this paper, we outline a theory of linguistic structure which talks about talking about trees; we call this theory Description theory (D-theory). While important issues must be resolved before a complete picture of D-theory emerges (and also before we can build programs which utilize it), we believe t...
