This paper describes a process for constructing situation-specific belief networks from a knowledge base of network fragments. A situation-specific network is a minimal query­ complete network constructed from a knowledge base in response to a query for the probability distribution on a set of target variables given evidence and context variables. We present definitions of query completeness an...

In this paper, we address the problem of detecting expressions of moral values in tweets using content analysis. This is a particularly challenging problem because moral values are often only implicitly signaled in language, and tweets contain little contextual information due to length constraints. To address these obstacles, we present a novel approach to automatically acquire background know...

This paper examines the use of mobile telephony in public spaces. It looks into the issue of how and why mobile telephony is seen as being disturbing. The two major issues are first, the way in which the device disturbs the web of front and back channel interactions found in a social setting and second the difficulties of managing issues surrounding eavesdropping and courtesy. The paper bases i...

There are many situations in which a customer’s proclivity to buy the product of any firm depends not only on the classical attributes of the product such as its price and quality, but also on who else is buying the same product. We model these situations as games in which firms compete for customers located in a “social network”. Nash Equilibrium (NE) in pure strategies exist in general. In th...
