towards a web of data?
DESCRIPTION
A presentation to Digital Sparks North West's Transmissions event on 21 July 2010 [http://transmission6.eventbrite.com/]. This presentation covers Linked Data and the Semantic Web, and uses the example of companies such as TripIt to demonstrate that a little semantics can go a long way. The presentation then explores more formal approaches, such as those underway within the UK Government, and asks whether or not this is feasible in a commercial context.TRANSCRIPT

simply making an existing task easier and richer
text processing, back-end knowledge, APIs
semantic knowledge of place, time, etc
valuable data on intentions, choices, preferences and more
adds value, without shouting about it.

semantic smarts
‘cheap sushi’ and ‘great sushi’ require analysis of different data, and may result in different recommendations.

“the Web done right”
Sir Tim Berners-Lee, 2008
harks back to TimBL’s original vision for a Read/Write Web

Use URIs to name things
Use HTTP URIs so that they can be followed
When someone follows a URI, provide useful information
Include links to other URIs, so that more can be discovered.

What does this mean for Enterprise?

Closing Thoughts
cloudofdata.com www.flickr.com/photos/king-edward/2152782252/
semantics on the web bring value
sometimes solving quite narrow problems
The Semantic Web is part of that
but only part
Open Data creates opportunities, and challenges business models
Linked Data takes us beyond specific applications
This isn’t just for the public sector.
