The power of web services can only be realized when web services are utilized as building blocks to dynamically compose new web services. The Building Finder application is an example application that integrates information from several web services by modeling the web services as information sources in a mediator-based architecture. The paper also describes a mediator framework to dynamically ...

Nitpick is a counterexample generator for Isabelle/HOL that builds on Kodkod, a SAT-based firstorder relational model finder. Nitpick supports unbounded quantification, (co)inductive predicates and datatypes, and (co)recursive functions. Fundamentally a finite model finder, it approximates infinite types by finite subsets. Our experimental results on Isabelle theories and the TPTP library indic...

We develop an intelligent agent that builds a user model of a learner during a tour of a virtual world. The user model is based on the learner’s answers to questions during the tour. A dialogue model for a simulated instructor is tailored to the individual learner based upon this user model. We describe an evaluation to track system accuracy and user perceptions.

For this the DTG interrogates Tour Building Blocks (TBB), e.g. potential sights or restaurants, to determine current information, e.g. opening hours or availability. An ontology is used to capture the profiles of ...
