Abstract:
How do we cope with the ever-increasing amount of available information? Can we create computational tools that facilitate the exploratory process inherent in scientific discovery? With a motivating example I encountered in my work in geometry processing, I will present research on managing the provenance of computational processes with VisTrails, a novel scientific visualization system I have helped design and develop. Besides facilitating reproducibility and sharing of results, I will show how this provenance data can be reused to ease the exploration process, derive semi-automatic changes to visualizations and automatically suggest meaningful completions. I will then discuss the impact of the work, and show scenarios where VisTrails is being deployed. Finally, I will talk about some of the outstanding problems in analysing the acquired provenance data, focusing on aspects related to social data analysis.
