Abstract Question answering (QA) systems provide a way of querying the information available in various formats including, but not limited to, unstructured and structured data natural languages. It constitutes considerable part conversational artificial intelligence (AI) which has led to introduction special research topic on question (CQA), wherein system is required understand given context t...

Topic models have been thoroughly investigated for multiple years due to their great potential in analyzing and understanding texts. Recently, researchers combine the study of topic with deep learning techniques, known as Neural Models (NTMs). However, existing NTMs are mainly tested based on general document modeling without considering different textual analysis scenarios. We assume that ther...

Conversational agent is a system that provides user with proper information and maintains the context of dialogue based on natural language. When experts design the network for conversational agent of a domain, the network is usually very complicated and is hard to be understood. So the simplification of network by separating variables in the domain is helpful to design the conversational agent...

Gaze is instrumental in coordinating face-to-face social interactions. But little is known about gaze use when social interactions co-occur with other joint activities. We investigated the case of walking while talking. We assessed how gaze gets allocated among various targets in mobile conversations, whether allocation of gaze to other targets affects conversational coordination, and whether r...

This paper presents our recent work on language identi-cation research using conversational speech (the LDC Conversational Telephone Speech Database). The base-line system used in this study was developed recently ((4, 5]). It is based on language-dependent phone recognition and phonotactic constraints. The system was trained using monologue data and obtained an error rate of around 9% on a com...

Automated analyses of full-day recordings were used to determine whether young children who are hard-of-hearing (HH) received similar levels of exposure to adult words and conversational interactions as age-matched peers with normal-hearing (NH). Differences in adult input between children in this study and in a normative database were considered. Finally, factors were examined that may have co...

The activity of speaking is conducted spontaneously and there is not much time devoted to preplanning and arranging the utterances the speaker intends to deliver. Briefly defined, gambits and routines refer to the words and phrases that facilitate the flow of conversations. As such, one way to help learners acquire oral proficiency is to teach gambits that support the social skills emphasized. ...
