While some recent work in tutorial dialogue has touched upon tutor reformulations of student contributions, there has not yet been an attempt to characterize the intentions of refor-mulations in this educational context nor an attempt to determine which types of reformu-lation actually contribute to student learning. In this paper we take an initial look at(More)
Rimac is a natural-language intelligent tutoring system that engages students in dialogues that address physics concepts and principles, after they have solved quantitative physics problems. Much research has been devoted to identifying features of tutorial dialogue that can explain its effectiveness (e.g., [1]), so that these features can be simulated in(More)
BACKGROUND The persistent colonization of paranasal sinus mucosa by microbial biofilms is a major factor in the pathogenesis of chronic rhinosinusitis (CRS). Control of microorganisms within biofilms is hampered by the presence of viscous extracellular polymers of host or microbial origin, including nucleic acids. The aim of this study was to investigate(More)
Plastic debris has been documented in many marine ecosystems, including remote coastlines, the water column, the deep sea, and subtropical gyres. The North Pacific Subtropical Gyre (NPSG), colloquially called the "Great Pacific Garbage Patch," has been an area of particular scientific and public concern. However, quantitative assessments of the extent and(More)
This poster describes Rimac, a natural-language tutoring system that engages students in dialogues that address physics concepts and principles, after students have solved quantitative physics problems. We summarize our approach to deriving decision rules that simulate the highly interactive nature of human tutoring, and describe a pilot test that compares(More)
Research in proteomics has exploded in recent years with advances in mass spectrometry capabilities that have led to the characterization of numerous proteomes, including those from viruses, bacteria, and yeast. In comparison, analysis of the human proteome lags behind, partially due to the sheer number of proteins which must be studied, but also the(More)
Plankton imaging systems are capable of providing fine-scale observations that enhance our understanding of key physical and biological processes. However, processing the large volumes of data collected by imaging systems remains a major obstacle for their employment, and existing approaches are designed either for images acquired under laboratory(More)
In this paper we explore the question of whether additional benefits can be derived from providing formative feedback on students' explanations given the difficulties of accurately assessing them automatically. We provide a preliminary evaluation of an approach in which students assist in interpreting their own explanations and we lay out our plans for(More)
The INLG 2012 program consists of presentations of substantial, original, and previously unpublished results on all topics related to natural language generation. This year we received 27 submissions (12 full papers, 9 short papers and 6 demo proposals) from 10 different countries from around the world. As in previous years, each submission was reviewed by(More)
Education has always been the hallmark of man's progress in the civilized world. In the past few decades we have seen the face of the classroom change by including more and more electronic devices like projectors, tablet PC's and computers. Mi-Clicker is revolutionary interactive mobile application software for students. The Mi-Clicker encourages student(More)
