More and more companies allow users to bring their own IT devices to the workplace. As a result, an increased heterogeneity of hardand software makes it challenging to deliver central IT support. Therefore, employees might increasingly rely on the help of their colleagues. In such a user-to-user support scenario, traditional communication media such as text chat and telephone are used. In this ...

This study explored learners’ attitudes toward collaborative writing in pairs and small groups (fours sixes) a synchronous web-based environment. Sophomore pre-service teachers one intact class the Philippines (n=31) completed same tasks using Google Docs. In three separate out-of-class sessions, they first worked pairs, then were assigned to either of four or six succeeding two sessions. After...

In this paper, the latest version of an emotion extraction engine used for real time Internet text communication is presented. The engine can analyse input text from a chat environment, extract the emotion being communicated, and deliver the parameters necessary to invoke an appropriate expressive image on screen to the communicating user display. The parameters include the emotion extracted fr...

We describe two advanced video analysis techniques, including video-indexed by voice annotations (VIVA) and multi-media indexing and explorer (MINER). VIVA utilizes analyst call-outs (ACOs) in the form of chat messages (voice-to-text) to associate labels with video target tracks, to designate spatial-temporal activity boundaries and to augment video tracking in challenging scenarios. Challengin...

Motivation To understand the molecular mechanisms involved in cancer development, significant efforts are being invested in cancer research. This has resulted in millions of scientific articles. An efficient and thorough review of the existing literature is crucially important to drive new research. This time-demanding task can be supported by emerging computational approaches based on text min...

Meaning making is central to the interactions that take place in CSCL settings. The collaborative construction of shared meaning is a complex process that has not previously been analyzed in detail despite the fact that it is often acknowledged as being the distinguishing element in CSCL. Here, a three-minute excerpt from a discussion among three students is considered in some detail. The stude...

The Math Forum is an online resource center for pre-algebra, algebra, geometry and pre-calculus. Its Virtual Math Teams (VMT) service provides an integrated web-based environment for small teams of people to discuss math and to work collaboratively on math problems or explore interesting mathematical micro-worlds together. The VMT Project studies the online math discourse that takes place durin...
