A PDTB-Styled End-to-End Discourse Parser
We have developed a full discourse parser in the Penn Discourse Treebank
(PDTB) style. Our trained parser first identifies all discourse and
non-discourse relations, locates and labels their arguments, and then
classifies their relation types. When appropriate, the attribution spans to
these relations are also determined. We present a comprehensive evaluation from
both component-wise and error-cascading perspectives.Comment: 15 pages, 5 figures, 7 table
Estudios acerca del establecimiento de conexiones entre enunciados hablados: ¿qué pueden contribuir a la promoción de la construcción de una representación coherente del discurso por parte de los estudiantes?
The aim of this article is to provide an overview of how the establishment of discourse connections among spoken statements has been studied by approaches to discourse analysis and psycholinguistic studies, in order to highlight what variables appear to be important for understanding how comprehension of spoken discourse can be facilitated. The consideration of discourse analysis approaches allows us to think about the role of the establishment of discourse connections among speech acts in the classroom, the uses of contextualization cues by bilingual students, the identification of social and cultural notions in teachers’ discourse, and the interactional effects of teachers’ interventions. Preliminary psycholinguistic studies contribute to our understanding of the role of establishing causal connections and integrating adjacent statements through the presence of discourse markers in the comprehension of spoken discourse by college students. The results of these approaches and studies provide insight into students’ comprehension of classroom discourse, and hold the potential for implications for instruction.El propósito de este artÃculo es realizar un recorrido a través de enfoques de análisis del discurso y estudios de psicolingüÃstica que han investigado el establecimiento de conexiones entre enunciados hablados, a fin de destacar las variables que parecen ser centrales para facilitar la comprensión. La consideración de los enfoques del análisis del discurso nos permitirán pensar acerca del rol del establecimiento de conexiones entre actos del lenguaje en el aula, las funciones de las claves de contextualización, la identificación de las nociones sociales y culturales en el discurso de los profesores, los efectos de las intervenciones de los profesores en la interacción con los estudiantes. Los estudios preliminares de psicolingüÃstica contribuirán a nuestra comprensión del rol del establecimiento de conexiones causales e integración de enunciados adyacentes a través de marcadores del discurso por parte de estudiantes universitarios. La consideración de estos enfoques y estudios nos ayudarán a pensar acerca de las contribuciones que sus propuestas y métodos pueden hacer al enriquecimiento de nuestro entendimiento de cómo los estudiantes comprenden el discurso producido durante las clases.Fil: Yomha Cevasco, Jazmin.

Is writing style predictive of scientific fraud?
The problem of detecting scientific fraud using machine learning was recently
introduced, with initial, positive results from a model taking into account
various general indicators. The results seem to suggest that writing style is
predictive of scientific fraud. We revisit these initial experiments, and show
that the leave-one-out testing procedure they used likely leads to a slight
over-estimate of the predictability, but also that simple models can outperform
their proposed model by some margin. We go on to explore more abstract
linguistic features, such as linguistic complexity and discourse structure,
only to obtain negative results. Upon analyzing our models, we do see some
interesting patterns, though: Scientific fraud, for examples, contains less
comparison, as well as different types of hedging and ways of presenting
logical reasoning.Comment: To appear in the Proceedings of the Workshop on Stylistic Variation
