[Notes] Manfred Hauswirth at #SSSW2013

It's a dynamic world! Ubiquitous streams and the Linked Data Web from Manfred Hauswirth (pooh42)

Streams: Any time dependant data / changes over time.

Has done a paper about P2P stuff.

Data silo - "natural enemy of SW scientists"

Massive exponential growth of global data.

Still have to integrate dynamic data with static data.
Multiway joins are domintion operator. Need to be efficient.

Everything/body is a sensor.

Various research challenges:

CoAP ~= http for sensors.

Stuff about sensor networks and context - useful for Michael.

Rewrite query to spit out static and dynamic - lots of overhead.
But need to optimise between these.
Neither existing stream processing systems nor existing databases could be efficient enough.
So the built own LD stream processing system. (Optimised and adopted existing database stuff).

HyperWave - didn't succeed. Didn't listen to customers and wasn't open source (license fees).
But better than hypertext was back in the day.
Performance important for success/uptake.

Just putting it on cloud infrastructure doesn't mean it scales.

To do?

World is:
... uncertain, fuzzy, contradictory.
So combine statistics and logics.
Hard to scale logical reasoning, so use statistics to shoot in the right direction.


Don't get hung up on approaches / labels.
