This paper presents an approach to detecting and correcting edit disfluency based on conditional random fields with variable-length features. The variable-length features consist of word, chunk and sentence features. Conditional random fields (CRF) are adopted to model the properties of the edit disfluency, including repair, repetition and restart, for edit disfluency detection. For the evaluat...

In this paper we explore how a conversational virtual human could be designed to be deployed as a socially acceptable autonomous assistive system for elderly and cognitively impaired users. In particular, we focus on a system’s functionality in helping to maintain a well-structured daily life. We present initial findings from two types of studies: (1) Conducting interviews and focus groups cons...

obviously, learning environment plays a crucial role in how second language or a foreign language is learned. in this regard, the importance of interaction for l2 learning has been emphasized. the current study investigated teachers' interactional moves (im) and learners' uptake in efl classrooms systematically. to meet this end, four efl contexts of speaking and listening courses for...

The conversational agent understands and provides users with proper information based on natural language. Conventional agents based on pattern matching have many restrictions to manage various types of real dialogues and to improve the answering performance. For the effective construction of conversational agents, we propose a domain-adaptive conversational agent that infers the user’s intenti...

Conversational case-based reasoning (CBR) systems, which incrementally extract a query description through a user-directed conversation , are advertised for their ease of use. However, designing large case libraries that have good performance (i.e., precision and querying ee-ciency) is diicult. CBR vendors provide guidelines for designing these libraries manually, but the guidelines are diicult...

This paper introduces a Vietnamese text-based conversational agent architecture on specific knowledge domain which is integrated in a question answering system. When the question answering system fails to provide answers to users’ input, our conversational agent can step in to interact with users to provide answers to users. Experimental results are promising where our Vietnamese text-based con...

In this paper we present a framework for conversational awareness and conflict resolution in spoken dialogue systems for home care assistance. Conversational awareness is supported through OWL ontologies for capturing conversational modalities, while interpretation and incremental context enrichment is facilitated through Description Logics reasoning. Conflict resolution further assists the int...

The therapeutic relationship is the greatest predictor of treatment outcome, yet its relationship to communication is largely unevaluated. This study explored how psychiatrists and people with a diagnosis of schizophrenia establish mutual understanding in naturalistic communication, and associations with the therapeutic relationship, patient satisfaction and symptoms. In conversation analysis, ...
