  In this paper, we present SATIS, a framework to derive Web Service
specifications from end-user's requirements in order to opera-tionalise
business processes in the context of a specific application domain. The aim of
SATIS is to provide to neuroscientists, which are not familiar with computer
science, a complete solution to easily find a set of Web Services to implement
an image processing pipeline. More precisely, our framework offers the
capability to capture high-level end-user's requirements in an iterative and
incremental way and to turn them into queries to retrieve Web Services
description. The whole framework relies on reusable and combinable elements
which can be shared out by a community of users sharing some interest or
problems for a given topic. In our approach, we adopt Web semantic languages
and models as a unified framework to deal with end-user's requirements and Web
Service descriptions in order to take advantage of their reasoning and
traceability capabilities.
