I like this insight into IBM's Social Networks & Discovery (SaND) research and their focus on filter improvements to identify contextually relevant people, documents and expertise within the enterprise.
For me, this represents an early example of Phase 3 in my five phased roadmap of Enterprise communication and collaboration software. Phase 3 is about adding filtering and sensing features that make enterprise applications "aware" (e.g. context-aware, location-aware and social-aware) based on simple analysis of our personal ambient and declarative data.
"the IBM aggregation and filtering system works on any entity in a system–people, textual documents, or meta-information (tags). Like Google, searching on any term returns a ranked results list. But unlike Google, pausing over a link shows the relationships between people, tags, and documents"…
"As this information proliferation grows–on both sides of the firewall–filtering relevant people and content will only become more necessary"
