The objective of this research is to reduce confusion in chat conversation, which is the main problem regarding the use of chat tools for holding online course debates. This problem is investigated using a Groupware Engineering approach. A number of successive versions of the Mediated Chat tool have been developed as part of this research. This research aims at producing an enhanced chat tool d...

Knowledge sharing is crucial for companies in knowledge-intensive domains, but poses challenges for firms operating in a project-based manner. One domain facing this challenge is agile software business, which is based on autonomous teams and where the technological progress poses a constant need to update programmers’ knowledge.

Highly connected nodes (hubs) in biological networks are topologically important to the structure of the network and have also been shown to be preferentially associated with a range of phenotypes of interest. The relative importance of a hub node, however, can change depending on the biological context. Here, we report a Cytoscape app, the Contextual Hub Analysis Tool (CHAT), which enables use...

Chatrooms, for example Internet Relay Chat, are generally multi-user, multi-channel and multi-server chat-systems, which run over the Internet and provide a protocol for real-time text-based conferencing between users all over the world. While a well-trained human observer is able to understand who is chatting with whom, there are no efficient and accurate automated tools to determine the group...

This paper gives an overall account of a prototype natural language question answering system, called Chat-80 . Chat-80 has been designed to be both efficient and easily adaptable to a variety of applications. The system is implemented entirely in Prolog, a programming language based on logic. With the aid of a logic-based grammar formalism called extraposition grammars, Chat-80 translates Engl...

BACKGROUND It has been previously shown that cultured granulosa cells (GCs) derived from human ovarian preovulatory follicles contain choline acetyltransferase (ChAT), the enzyme responsible for acetylcholine (ACh) synthesis. They also produce ACh and express functional muscarinic ACh receptors. ACh can act on GCs to increase proliferation, disrupt gap junctional communication, alter intracellu...

BACKGROUND In European countries, including Switzerland, as well as in many states worldwide, cannabis is the most widely used psychoactive substance after alcohol and tobacco. Although approximately one in ten users develop serious problems of dependency, only a minority attends outpatient addiction counseling centers.
