Scientific Workflow Composition in E-Science

An important element in e-Science research is the scientific workflow that, in general, is very long, composed of many computations, and represents a scientific process. Generally, a scientific workflow is very large what turns it difficult to be defined. One possibility to help its definition is using tools that aggregate semantics to assist in the composition. In this context, this paper presents a proposal that aims to make possible the composition of scientific workflows, considering semantic search of web services and incorporating them in the workflows definition.
