This document specifies an application-level protocol (i.e., payload type) for chat tools using the Real Time Protocol for Distributed Interactive Media (RTP/I). RTP/I defines a standardized framing for the transmission of application data and provides protocol mechanisms that are universally needed for the class of distributed interactive media. A chat tool provides an instant messaging servic...

An e-mentoring system is an online tool that enables interactive mentoring between a mentor and a mentee, regardless of place and time differences. This paper discusses the system design of an e-mentoring system for Malaysian orphans, called MyMentorMentee.com. The design of MyMentorMentee.com is an adaptation of Keller's ARCS Motivational model and uses its motivational elements to provide an ...

A mobile user's presence and location information often forms important input for those applications and services that must anticipate on the user's context. Additionally, the ability to let a mobile device determine its location in an indoor environment at a fine-grained level supports the creation of a new range of personalized mobile Internet applications. The framework described here joins ...

Mashups are defined to be lightweight Web applications aggregating data from different Web services, built using ad-hoc composition and being not concerned with long term stability and robustness. In this paper we present a pattern based approach, called Mashup Processing Network (MPN). The idea is based on Event Processing Network and is supposed to facilitate the creation, modeling and the ve...

This paper proposes a new, efficient method of building a scalable generic application which can be used to provide various types of information services using mobile messaging. For specific information, mobile users send an SMS (Short Message Service) to the mobile gateway in a proper format which is then forwarded to the generic application. The generic application accordingly creates an auto...

In this paper, we summarize our work on the UDT high performance data transport protocol in the past four years. UDT was designed to effectively utilize the rapidly emerging high-speed wide area optical networks. It is built on the top of UDP with reliability control and congestion control, which makes it quite easy to get installed. The congestion control algorithm is the major internal functi...

SMS messaging technology allows for short messages to be exchanged between individuals at a relatively low cost. Current SMS messaging technology is limited to person-to-person messaging; many other forms of social communication also allow for person-to-location messaging. This is particularly important for domestic messaging since messages may need to be broadcast to an entire family or househ...

Nowadays, short texts are very prevalent in various web applications, such as microblogs, instant messages. The severe sparsity of short texts hinders existing topic models to learn reliable topics. In this paper, we propose a novel way to tackle this problem. The key idea is to learn topics by exploring term correlation data, rather than the high-dimensional and sparse term occurrence informat...
