A user interface to build interactive visualizations for the semantic web

While the web of linked data gets increasingly richer in size and complexity, its use is still constrained by the lack of applications consuming this data. We propose a Web-based tool to build and execute complex applications to transform, integrate and visualize SemanticWeb data. Applications are composed as pipelines of a few basic components and completely based on Semantic Web standards, including SPARQL Construct for data transformation and SPARQL Update for state transition. The main novelty of the approach lays in the support to interaction, through the availability of user interface event streams as pipeline inputs.
