DISCUSS: A dialogue move taxonomy layered over semantic representations

چکیده
In this paper we describe DISCUSS, a dialogue move taxonomy layered over semantic representations. We designed this scheme to enable development of computational models of tutorial dialogues and to provide an intermediate representation suitable for question and tutorial act generation. As such, DISCUSS captures semantic and pragmatic elements across four dimensions: Dialogue Act, Rhetorical Form, Predicate Type, Semantic Roles. Together these dimensions provide a summary of an utterance’s propositional content and how it may change the underlying information state of the conversation. This taxonomy builds on previous work in both general dialogue act taxonomies as well as work in tutorial act and tutorial question categorization. The types and values found within our taxonomy are based on preliminary observations and on-going annotation from our corpus of multimodal tutorial dialogues for elementary school science education.

A Classification of Dialogue Actions in Tutorial Dialogue
In this paper we present a taxonomy of dialogue moves which describe the actions that students and tutors perform in tutorial dialogue. We are motivated by the need for a categorisation of such actions in order to develop computational models for tutorial dialogue. As such, we build both on existing work on dialogue move categorisation for tutorial dialogue as well as dialogue taxonomies for ge...
متن کاملEvaluating Questions in Context
We present an evaluation methodology and a system for ranking questions within the context of a multimodal tutorial dialogue. Such a framework has applications for automatic question selection and generation in intelligent tutoring systems. To create this ranking system we manually author candidate questions for specific points in a dialogue and have raters assign scores to these questions. To ...
متن کاملA Multidimensional Approach to Multimodal Dialogue Act Annotation
This paper investigates the benefits of multidimensional approaches to dialogue act annotation, and the advantages of using layered multidimensional ’open’ dialogue act taxonomies. We performed a comparative analysis of a one-dimensional and two multidimensional dialogue act annotation schemes, and concluded that not only does a multidimensional approach support a more accurate analysis of huma...
متن کاملEEH: AGGH-like public key cryptosystem over the eisenstein integers using polynomial representations
GGH class of public-key cryptosystems relies on computational problems based on the closest vector problem (CVP) in lattices for their security. The subject of lattice based cryptography is very active and there have recently been new ideas that revolutionized the field. We present EEH, a GGH-Like public key cryptosystem based on the Eisenstein integers Z [ζ3] where ζ3 is a primitive...
متن کاملIncremental Construction of Robust but Deep Semantic Representations for Use in Responsive Dialogue Systems
It is widely acknowledged that current dialogue systems are held back by a lack of flexibility, both in their turn-taking model (typically, allowing only a strict back-and-forth between user and system) and in their interpretation capabilities (typically, restricted to slot filling). We have developed a component for NLU that attempts to address both of these challenges, by a) constructing robu...
