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...

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...

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...

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...

The abuse of chat services by automated programs, known as chat bots, poses a serious threat to Internet users. Chat bots target popular chat networks to distribute spam and malware. In this paper, we first conduct a series of measurements on a large commercial chat network. Our measurements capture a total of 14 different types of chat bots ranging from simple to advanced. Moreover, we observe...

Chatting is a popular communication media on the Internet via ICQ, chat rooms, etc. Chat language is different from natural language due to its anomalous and dynamic natures, which renders conventional NLP tools inapplicable. The dynamic problem is enormously troublesome because it makes static chat language corpus outdated quickly in representing contemporary chat language. To address the dyna...
