IEEE eScience: Web services architecture for visualization Web services architecture for visualization
Jeremy Walton, Numerical Algorithms Group

convert data to information leading to knowledge
visualization and statistical analysis – visual analytics

ADVISE system–
- visual analytics
- enables creation of analysis application (generic or domain specific)
- service oriented architecture

2 existing systems
IRIS explorer – visualization algorithms
GenStat – statistical algorithms

merge these > advise > clients
3 layers visualization components > web services middleware > user interface

modules connected in pipelines
(modules from the older systems, plus some new ones)
middleware – stateful service so that data in calls can be re-used, maintains a model of pipeline state..

user interface – in java, can use pre-built pipelines or build your own….
(he demoed one where you could pick off the modules and build it – and another with dropdown boxes and a go button)

future work-
real user data sets
intelligent data types (streaming data – that’s cool but does it come packaged?, sharing large data)
more fine grained visualization services
connecting to other web services
