Composing multiple variability artifacts to assemble coherent workflows

Composing and Analyzing Crowdsourcing Workflows

When trying to crowdsource complex tasks, it is often better to break the big task into a set of smaller tasks and connect them into a production workflow [Little et al. 2009; Little et al. 2010]. Such workflows often allow a set of workers to work together in a task, creating an “assembly line for knowledge work” and allow the completion of tasks that are too complex or difficult for any parti...

A Systematic Approach to Composing and Optimizing Application Workflows

Composing Workflows of Semantic Web Services

Web services are software components that can be accessed over the Internet by other software components. Web service workflows are a set of web services that are executed in a structured way. This paper introduces a workflow composer agent, which is able to compose web service workflows, and more importantly, uses semantic descriptions of web services in finding and matching web services for a...

Composing E-Workflows Using Syntactic, Operational and Semantic Information

With the development and maturity of infrastructures that support e-services, we expect organizations to incorporate Web services as part of their business processes. While in some cases Web services may be utilized in an isolated form, it is natural to expect that Web services will be integrated as part of workflows. The composition of workflows to model e-service applications differs from the...

Automatically Composing Data Workflows with Relational Descriptions and Shim Services

Many scienti c problems can be represented as computational work ows of operations that access remote data, integrate heterogeneous data, and analyze and derive new data. Even when the data access and processing operations are implemented as web or grid services, work ows are often constructed manually in languages such as BPEL. Adding semantic descriptions of the services enables automatic or ...
