In this paper, we present an application for the automatic identification of the important moments that might occur during students’ collaborative chats. The moments are detected based on the input received from the user, who may choose to perform an analysis on the topics that interest him/her. Moreover, the application offers various types of suggestive and intuitive graphics that aid the use...

We consider the task of classifying chat contributions by dialogue act in a multi-party setting. This extends the problem significantly over the 1-1 chat scenario due to the semiasynchronous and “entangled” nature of the contributions by chat participants. We experiment with a number of machine learning approaches, using different categories of features: lexical, contextual, structural, keyword...

The nervous system plays a profound regulatory role in maintaining appropriate immune responses by signaling to immune cells. These immune cells, including B- and T-cells, can further act as intermediary messengers, with subsets of B- and T-cells expressing choline acetyltransferase (ChAT), the enzyme required for acetylcholine (ACh) synthesis. Neural control of ACh release from ChAT+ T-cells c...

The problem in processing Chinese chat text originates from the anomalous characteristics and dynamic nature of such a text genre. That is, it uses ill-edited terms and anomalous writing styles in chat text, and the anomaly is created and discarded very quickly. To handle this problem, one solution is to re-train the recognizer periodically. This costs a lot of manpower in producing the timely ...

la morphologie, c’est l’étude des formes ou bien la mise en place des éléments constitutifs du conte. le travail de vladimir propp consiste à étudier non pas le contenu des contes folkloriques mais le contenant, c’est-à-dire la forme extérieure des contes et leur structure globale. ainsi, l’analyse de le petit poucet et de le chat botté fait appel à une logique fictionnelle propre au merveilleu...

Introduction: Maintenance of neurogenesis depends on the function of some histone-modifying enzymes; including Enhancer of zeste homolog 2 (EZH2) and histone acetyltransferases (P300). The mechanism of epigenetic regulation and gene expression underlying the transition of human umbilical cord blood mesenchymal stem cells (hUCB-MSCs) into MNs has not been fully clarified.  Methods: Two morphoge...

Prior research has shown that intermediate-level adult learners of Russian who worked interactively with partners using text chat improved their vocabulary and oral production skills more than students who worked independently (Tare et al., 2014). Drawing on the dataset from Tare et al. (2014), the current study follows up to explore the nature of the students’ (N = 25) interactions during the ...
