ILIADS Goal:
Produce high-quality integration via a flexible method able to adapt to a wide variety of ontology sizes and structures
Method: Combining statistical and logical inference Use schema (structure) and data (instances) effectively
Solution: Integrated Learning In Alignment of Data and Schema
(ILIADS)

Future: Focus on Integrated Tasks
Putting it all together… Bioinformatics Computer Vision Natural Language Processing Personal Information Management

Research Agenda Visual Analytics
Complexity of the integrated SRL tasks require sophisticated user interfaces which allow user feedback and support explanation
Query-time adaptive information gathering Complexity of the integrated SRL tasks require flexible, adaptive
algorithms which retrieve relevant information in real time
Some related areas to keep in mind: resurgence of work in probabilistic databases (DB), social network analysis (social science), network science (physicists)

D-Dupe: An Interactive Tool for Entity Resolution
http://www.cs.umd.edu/projects/linqs/ddupe
Novel combination ofnetwork visualization and statistical relational models
well-suited to the visual analytic task at hand
