This study examined the capacity of text-based online chat to promote learners’ noticing of their problematic language productions and of the interactional feedback from their interlocutors. In this study, twelve ESL learners formed six mixed-proficiency dyads. The same dyads worked on two spot-thedifference tasks, one via online chat and the other through face-to-face conversation. Stimulated ...

Online text chat is a very popular Internet-based application. Previous studies have identified several problems with standard text chat systems. Real-time collaborative editing systems can be used for text chat. This paper compares text chat via collaborative editing systems with text chat via standard text chat systems. It has been identified that standard text chat system do not maintain som...

Mostly, the conversations taking place in chat mediums bear important information concerning the speakers. This information can vary in many fields such as tendencies, habits, attitudes, guilt situations, and intentions of the speakers. Therefore, analysis and processing of these conversations are of much importance. Many social and semantic inferences can be made from these conversations. In d...

This paper is an attempt to move the literature on chat-based reference services beyond the current spate of case studies and discussions of emerging standards and best practices in providing chat-based reference, to a higher level of discussion on the creation and discussion of theoretical frameworks to unite these standards and practices. This paper explores the various steps in the process o...

In recent years many online text chat systems have been developed and use. Internet Relay Chat or IRC, ICQ, AOL and MSN are some examples of the most popular tools for real-time communications via the Internet and have been used both for doing serious work [4], decision making [5] and for entertainment purpose. Messaging programs tend to imitate each other and they imitate other chat programs e...

We propose AliMe Chat, an open-domain chatbot engine that integrates the joint results of Information Retrieval (IR) and Sequence to Sequence (Seq2Seq) based generation models. AliMe Chat uses an attentive Seq2Seq based rerank model to optimize the joint results. Extensive experiments show our engine outperforms both IR and generation based models. We launch AliMe Chat for a real-world industri...

This paper introduces a text-based chat system designed to support conversations anchored to specific locations of shared images and reports our experience in operating it at WISS2004. Our system is unique in that it focuses on supporting communications scattered around among multiple images, while other systems for anchored conversations are designed for deeper discussions within a single docu...

INTRODUCTION Mobile health interventions have the potential to promote risk factor management and lifestyle modification, and are a particularly attractive approach for scaling across healthcare systems with limited resources. We are conducting two randomised trials to evaluate the efficacy of text message-based health messages in improving secondary coronary heart disease (CHD) prevention amon...

Malicious users on chat network systems would reduce the willingness of benevolent users to chat on the same network. Thus it is often desirable to classify malicious users based on their personal profile and chat contents. In this study, different algorithms including Naive Bayes, SVM, Decision Table, Multilayer Perceptron, and Logistic classification are applied on the dataset from an anonymo...

Chat rooms and newsgroup on the internet is a valuable, and often free of charge, source of information. In this paper, a design of smart chat room bots that automatically retrieve and filter on line messages is proposed. The design is based on internet technology and Bayesian Networks. Technical details of connecting to and retrieving data from web based chat room servers are presented. A Naiv...
