Information visualization techniques have been successfully used to build visual and
interactive analysis of data and data relationships. However, dimensionality, volume and …

Knowledge of structure is critical to map legacy workflows to environments suitable to run on
the cloud. We present a method which characterizes a workflow structure with the execution …

Scientific workflows describe the scientific process from experimental design, data capture,
integration, processing, and analysis that leads to scientific discovery. Laboratory …

Resource discovery systems may assist scientists in the selection of bioinformatics
resources suitable to implement scientific workflows. In this paper we address several …

We present a deductive approach that supports resource discovery. The BiOnMap Web
service is designed to support the selection of resources suitable to implement specific …

Scientific legacy workflows are often developed over many years, poorly documented and
implemented with scripting languages. In the context of our cross-disciplinary projects we …

Infrastructures that support reasoning on services and their composition into workflows are
critical to evaluate and improve performance. In this paper we present ProtocolDB, a system …

Scientific workflow management systems primarily consist of data flow oriented execution
models, and consequently, these systems provide a limited number of control flow constructs …

Low power consumption is emerging as a major design constraint in several digital
applications, out of which some present also high reliability requirements, that can be …

We present a model that supports Web service description, composition, and workflow
design. The model is composed of an ontological layer that represents domain concepts and …
