When Things Go Wrong: Interrupting Conversations

This paper presents a true-concurrent approach to formalising integration of Small-to-Medium Enterprises (SMEs) with Web services. Our approach formalises common notions in service-oriented computing such as conversations (interactions between clients and web services), multi-party conversations (interactions between multiple web services) and coordination protocols, which are central in a tran...

Periodic paralyses: when channels go wrong.

In 1865, Claude Bernard wrote that ‘the constancy of the internal milieu is the essential condition to a free and independent life’ [1]. It would be hard to find a more illustrative paradigm for that statement than for the case of hyperkalaemic periodic paralysis (HyperPP) reported by Grgic et al. in this issue [2]. A 14-year-old male was admitted for a sudden ascending paralysis involving the ...

Getting it right when things go wrong.

Understanding the Bethe approximation: when and how does it go wrong?

Belief propagation is a remarkably effective tool for inference, even when applied to networks with cycles. It may be viewed as a way to seek the minimum of the Bethe free energy, though with no convergence guarantee in general. A variational perspective shows that, compared to exact inference, this minimization employs two forms of approximation: (i) the true entropy is approximated by the Bet...

When calls go wrong: how to detect problematic calls based on log-files and emotions?

Traditionally, the prediction of problematic calls in Interactive Voice Response systems in call centers has been based either on dialog state transitions and recognition log data, or on caller emotion. We present a combined model incorporating both types of feature sets that achieved 79.22% classification accuracy of problematic and non-problematic calls after only the first four turns in a hu...
