Bootstrapping pay-as-you-go data integration systems
Data integration systems offer a uniform interface to a set of data sources. Despite recent progress, setting up and maintaining a data integration application still requires sign...

Expressing Priorities and External Probabilities in Process Algebra via Mixed Open/Closed Systems
Defining operational semantics for a process algebra is often based either on labeled transition systems that account for interaction with a context or on the so-called reduction ...

Discrete real-time and stochastic-time process algebra for performance analysis of distributed systems
We present a process algebra with conditionally distributed discrete-time delays and generally-distributed stochastic delays. The treatment allows for expansion laws for the paral...

A Prototypical System for Soft Evidential Update
Autonomous agents that communicate using probabilistic information and use Bayesian networks for knowledge representation need an update mechanism that goes beyond conditioning on ...
