We investigate and evaluate methods for the characterization of social relations from textual communication context, using e-mail as an example. Social relations are intrinsically characterized by the Cartesian product of weights on various axes (we employ valuation and intensity as examples). The prediction of these characteristics is performed by application of unsupervised learning algorithm...

We present in this paper the architecture of MetaTutor, an intelligent tutoring system that teaches students meta-cognitive strategies while learning about complex science topics. A more in-depth presentation of the micro-dialogue component in MetaTutor is provided. This component handles the meta-cognitive strategy of subgoal generation. This strategy involves subgoal assessment and feedback g...

This study examines the relationship between length of time since a patient received their first treatment for cancer and feedback they give on that treatment. The analysis is based corpus 214,340 written comments (14,403,694 words) relating to National Health Service (NHS) care in England 2015 2018. Patients are grouped according duration compared terms ratings gave, themes positive negative c...

In our paper we describe the structure and implementation of a semi-automatic evaluation environment for natural language processing in speech understanding systems. The major goal of this evaluation framework is to support the construction of linguistic processors and their accompanying linguistic knowledge bases (grammars) in order to reduce development costs and raise quality. Our evaluation...

Novel labels provide feedback that may enhance categorical alignment between interlocutors. However, the nature of this feedback may not always be linguistic. Lupyan (2008) has demonstrated the effects of labels on individual categorization, and even non-word labels have seemingly produced greater consistency in sorting strategies (Lupyan & Casasanto, 2014). We extend this to alignment by demon...

This paper introduces a formal view of the semantics and pragmatics of corrective feedback in dialogues between adults and children. The goal of this research is to give a formal account of language coordination in dialogue, and semantic coordination in particular. Accounting for semantic coordination requires (1) a semantics, i.e. an architecture allowing for dynamic meanings and meaning updat...

The Linguistic Data Consortium (LDC) has created various annotated linguistic data for a variety of common task evaluation programs and projects to create shared linguistic resources. The majority of these annotated linguistic data were created with highly customized annotation tools developed at LDC. The Annotation Graph Toolkit (AGTK) has been used as a primary infrastructure for annotation t...

corrective feedback (cf) and its different types have long absorbed many scholars and practitioners. as ellis (2009) mentioned some experimental studies need to be carefully designed to discover the relative effectiveness of each of these cf techniques. the goal of this qualitative study was to discover whether the employment of different cf strategies could bring about an attitudinal shift. to...
