DESCRIPTION:Dr Dipanjan Chakraborty\, IBM Research\nPresence\, broadly def
 ined as an event publish-notification infrastructure for converged applica
 tions\, has emerged as a key mechanism for collecting and disseminating co
 ntext attributes for next-generation services in both enterprise and provi
 der domains.  Current presence-based solutions and products lack in the ab
 ility to a) support flexible user-defined queries over dynamic presence da
 ta and b) derive composite presence from multiple provider domains. Accord
 ingly\, current uses of context are limited to individual domains/organiza
 tions and do not provide a programmable mechanism for rapid creation of co
 ntext-aware services.\n\nThis work presents a large-scale presence virtual
 ization and federation platform that (a) federates across heterogeneous pr
 esence domains and thereby enables applications to exploit cross-domain co
 ntextual data\; (b) provides a programmatic interface for aggregating pres
 ence data from various sources and for composing base presence information
  into abstract\, functionally richer entities for enabling applications. A
 n underlying design consideration is to leverage capabilities of protocols
  that are being widely deployed today.\n\nThis is a joint research project
  between IBM T.J. Watson Research Center and IBM Research India. The platf
 orm has undergone customer trials.\n\nTime permitting\, In the later part 
 of the talk\, I plan to cover our work in the related area of real-time so
 cial networking\, and specifically talk about R-U-In? (pronounced Are you 
 in?) - an activity-oriented social networking prototype we have developed.
