We describe some common problems experienced by users of computer-based text chat, and show how many of these problems relate to the loss of timing-specific information. We suggest that thinking of chat as a streaming media data type might solve some of these problems. We then present a number of alternative chat interfaces along with results from user studies comparing and contrasting them bot...

The Internet has been utilized in several real life aspects such as online searching, and chatting. On the other hand, the Internet has been misused in communication of crime related matters. Monitoring of such communication would aid in crime detection or even crime prevention. This paper presents a text categorization approach for automatic monitoring of chat conversations since the current m...

This paper reports from an experimental study of cooperative work in a collaborative virtual environment (CVE) with sixty test subjects. A method from social psychology, interaction process analysis (IPA), was used for analyzing group dynamics within the CVE in relation to three communicative modes: text-chat, voice, and video conferencing. The study investigated how the communicative mode infl...

The goal is classification of microtext: classifying lines of military chat, or posts, which contain items of interest. This paper evaluates non-linear statistical data modeling techniques, and compares with our previous results using several text categorization and feature selection methodologies. The chat posts are examples of 'microtext', or text that is generally very short in length, semi-...

Quasi-synchronous chat consists of the production and posting of text messages in an online environment. It differs from face-to-face talk-in-interaction in a number of important ways that are significant for participants in the chats and methodologically in terms of the way analysis can be conducted and the kinds of analytical claims that can be made. The perspective adopted in this paper is t...

Overview This design project addresses the inherent ambiguities of text chat interfaces concerning which messages relate to which. Due to their linear nature, the relationship between two messages is not always obvious. A prototype of an application has been developed that allows users to structure their conversations in a mindmap or tree layout. Its use of space and color is designed to make i...

Chat-based Computer Supported Collaborative Learning (CSCL) often suffers from limitations due to the communication medium. A frequently reported consequence is the lack of discourse coherence and by this a lack of cognitive coherence in the learning process. To overcome these deficiencies, the implementation of explicit references with chat messages caused higher learning results. However up t...

Instant Messaging has become an important means of communication between people around the globe, providing an alternative to telephone and email conversations. The number of users using Instant Messenger products has been increasing over recent years. Messenger services provide a perfect environment for private and personal chat. People of all ages log into messenger service or chat rooms to s...

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...
