Presented by Liarou Erietta and Stratos Idreos (CWI) at The 10th International Semantic Web Conference (ISWC 2011), October 23-27, 2011, Bonn, Germany. Publication: http://bit.ly/HmIRZV ABSTRACT: The trend for more online linked data becomes stronger. Foreseeing a future where "everything" will be online and linked, we ask the critical question; what is next? We envision that managing, query- ing and storing large amounts of links and data is far from yet another query processing task. We highlight two distinct and promising research directions towards managing and making sense of linked data. We in- troduce linked views to help focusing on specific link and data instances and linked history to help observe how links and data change over time.

10. Data and Links Deluge
Challenges
• How to deal with so much data and so many links
• How to best exploit and make sense of the links
and data deluge

15. Linked views
• Dynamic, adaptive, personalized views of the Linked Data
• Different scientific points of view
• continue, refine and expand the search
• browse views to be inspired
• Create views in a crowd-sourcing way

30. Research Issues
• How can we create, store and maintain views
• full materialization will be impractical
• Who can access and modify an existing view?
• ideally we want to share and be inspired by others views
• Created by one, enriched by the crowd
• How can we store and maintain the history
• Efficient queries on history
• naive search would lead to millions of joins
• New languages and standards
• Views and History should be accessible from the Web
