The description of: Emerging Intelligent Data and Web Technologies (EIDWT-2011) is a call for software designed for non-human users.
The Social Life of Information by John Seely Brown and Paul Duguid, makes it clear that human users don’t want to share data because sharing data represents a loss of power/status.
A poll of the readers of CACM or Computer would report a universal experience of working in an office where information is hoarded up by individuals in order to increase their own status or power.
9/11 was preceded and followed by, to this day, by a non-sharing of intelligence data. Even national peril cannot overcome the non-sharing reflex with regard to data.
EIDWT-2011 and conferences like it, are predicated on a sharing of data known to not exist, at least among human users.
Hence, I suspect the call must be directed at software for non-human users.
