Title : An Ambient Agent Model Exploiting Workflow-Based Reasoning to Recognize Task Progress
| Presenter | Fiemke Both |
| Abstract | For an ambient intelligent agent to support a human in demanding tasks it is important to be aware of the progress made in a given workflow. It would be possible to interact with the human about this, but this may disturb task performance. In this paper an ambient agent model is presented that is able to obtain such an awareness of the human’s progress in a workflow by performing model-based analysis using available workflow models and available observation information. Simulation experiments for the presented the ambient agent model for a case study are discussed, and evaluated by automated formal verification. |
Title : What's wrong with web services. Part II: The Free Speech way
| Presenter | Ruud Stegers |
| Abstract | During my last talk I showed how existing web service protocols hinder building a truely open web of services. The remote function call style of implementing services introduces heavy restrictions on compatibility which are not driven by contraints from the domain, but follow only from the choice of protocol. Last time I did not provide any solution at all. This time I will focus on a solution: The Free Speech system. I'll introduce a new way of thinking about inter-service communication, and will replace 'communication by invocation' by true communication about the task at hand. The Free Speech system will be illlustra ted by actual output from a prototype implementation. |
