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...

People have generally been very ambivalent about the potential future roles of new technologies (and the internet specifically) and their possible effects on human society. Indeed, there has been a tendency for polarization between attitudes or perceptions of naive enthusiasm and cynical resistance towards the use of computers and computer networks, and for such related concepts as ‘the informa...

Over the last five to seven years the use of chat in military contexts has expanded quite significantly, in some cases becoming a primary means of communicating time-sensitive data to decision makers and operators. For example, during humanitarian operations with Joint Task Force-Katrina, chat was used extensively to plan, task, and coordinate predeployment and ongoing operations. The informal ...

In this study, we examined the links between Internet addiction, engagement in online erotica (including pornography usage and usage of sex-based Internet chat sites), and engagement in risky online sexual behaviors, in this case, sending sexually-explicit pictures to those known only online (i.e., sexting) and expecting to engage in offline sex with those known only online. In our sample of 27...

In Hong Kong, the discussion of youth internet chatting is largely framed as part and parcel of the broader emergence of internet “idling culture.” Surprisingly, there has been little news reports and columns that focus on the discussion of internet chatting in Hong Kong. When it does appear, most of them focus on internet crime, slander and sexual harassment; in other words, local news rarely ...

How do users behave in online chatrooms, where they instantaneously read and write posts? We analyzed about 2.5 million posts covering various topics in Internet relay channels, and found that user activity patterns follow known power-law and stretched exponential distributions, indicating that online chat activity is not different from other forms of communication. Analysing the emotional expr...

We have developed a system that streams and archives live sound from remote areas across Japan via an unmanned automatic camera. The system was used to carry out pilot bird censuses in woodland; this allowed us to examine the use of live sound transmission and the role of social media as a mediator in remote scientific monitoring. The system has been streaming sounds 8 h per day for more than f...

Multihomed subscribers are increasingly adopting intelligent route control solutions to optimize the cost and end-to-end performance of the traffic routed among the different links connecting their networks to the Internet. Until recently, IRC practices were not considered adverse, but new studies show that in a competitive environment, they can lead to persistent traffic oscillations, causing ...

We evaluate several different overlay routing structures for supporting interactivity features in End Sysytem Multicast. Interactivity features include low-bandwidth textual chat, as well as higher-bandwidth audio conferencing and immersive audio applications. Overlays are evaluated using real interaction patterns seen in IRC, as well as real join and leave patterns from an ESM video broadcast....
