We are developing a framework for interactive composition of services that assists users in sketching their requirements by analyzing the semantic description of the services. We are applying this framework to compose end-to-end simulations for earthquake scientists. We describe the requirements that an interactive framework poses to the representation of the services, and how the representations are exploited to support the interaction. We also describe an analysis tool that helps users create complete and correct compositions of web services.
