Computer-mediated environments provide an arena for learning to argue. We investigate to what extent student dyads’ online argumentation can be facilitated with collaboration scripts that (1) prompt learners to prepare individually, (2) create conflict, and (3) encourage productive collaboration and argumentation. A process analysis of the chats of the dyads showed that the scripted treatment g...

In this paper, we suggest a list of high-level features and study their applicability in detection of cyberpedophiles. We used a corpus of chats downloaded from www.perverted-justice.com and two negative datasets of different nature: cybersex logs available online and the NPS chat corpus. The SVM classification results show that the NPS data and the pedophiles’ conversations can be accurately d...

Between April 2020 and May 2021, a series of ten online panel discussions took place known as Fireside Chats to examine the transport implications pandemic. A wide ranging set topics diversity perspectives have made for rich source insight at time critical reflection sector. This article offers glimpse into issues it examined.

Many people started being concerned about their privacy in delivering private chats, photographs, contacts and other personal information through mobile instant messaging services. Fortunately, in the majority of mobile instant messaging services, encrypted communication channels (e.g., using the SSL/TLS protocols) are used by default to protect delivered messages against eavesdropping attacks....

Computer mediated communication (CMC) provides a way of incorporating participant interaction into online environments. Use of such features as discussion forums and chats enhance collaborative work and learning. For many, however, CMC may be an unfamiliar medium. To ensure a successful CMC event, it is essential to adequately prepare participants for CMC. A proposed four step model prepares pa...

This paper argues that one reason for the success of collaborative problem solving where individual attempts failed is the polyphonic character of work in small groups. Polyphony, a concept taken from music, may occur in chats for problem solving, transforming dialog into a “thinking device”: Different voices jointly construct a melody (story, or solution) and other voices adopt differential po...

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...

Data is the primary concern in data mining. Data Stream Mining is gaining a lot of practical significance with the huge online data generated from Sensors, Internet Relay Chats, Twitter, Facebook, Online Bank or ATM Transactions. The primary constraint in finding the frequent patterns in data streams is to perform only one time scan of the data with limited memory and requires less processing t...

Online interactive exchange offers the learner many opportunities to use the target language to negotiate both meaning and form in a social context that is crucial for second language acquisition. This paper discusses a pilot study using synchronous electronic chats combined with task-based instruction (TBI) to enhance learners’ communication skills. TBI focuses on the two-way exchange of infor...
