The potential of synchronous chat through the Internet to improve online learning experiences has rarely been discussed by researchers. The case study reported in this paper discovers the needs of synchronous communication and assesses the value of online chats in distance-learning environments. Both qualitative and quantitative methods were used to analyze the value of the chat sessions. Insig...

This paper describes the personalized normalization of a multilingual chat system that supports chatting in user defined short-forms or abbreviations. One of the major challenges for multilingual chat realized through machine translation technology is the normalization of non-standard, self-created short-forms in the chat message to standard words before translation. Due to the lack of training...

In this paper we investigate the implications of providing a real-time messaging interface in a Web-based citizen science game. Our study draws on data from two weeks of chat messages and survey responses collected from Eyewire, a highly successful citizen science game which enables players to take part in scientific enquiries, within a semi-gamified environment. Our analysis reveals that real-...

OBJECTIVE This study validates the Modified Checklist for Autism in Toddlers, Revised with Follow-up (M-CHAT-R/F), a screening tool for low-risk toddlers, and demonstrates improved utility compared with the original M-CHAT. METHODS Toddlers (N = 16,071) were screened during 18- and 24-month well-child care visits in metropolitan Atlanta and Connecticut. Parents of toddlers at risk on M-CHAT-R...

This system demonstration paper presents IRIS (Informal Response Interactive System), a chat-oriented dialogue system based on the vector space model framework. The system belongs to the class of examplebased dialogue systems and builds its chat capabilities on a dual search strategy over a large collection of dialogue samples. Additional strategies allowing for system adaptation and learning i...

CHAT offers an alternative to SLG-WAM for implementing the suspension and resumption of consumers: unlike SLG-WAM, it does not use freeze registers nor a complicated trail to preserve their execution environments. CHAT also limits the amount of copying of CAT, which was previously put forward as an alternative to SLG-WAM. Although experimental results show that in practice CHAT is competitive w...
