The Man Who Mistook His Wife for a Hat : And Other Clinical Tales by
In his most extraordinary book, "one of the great clinical writers of the 20th century" (The New York Times) recounts the case histories of patients lost in the bizarre, apparently inescapable world of neurological disorders. Oliver Sacks's The Man Who Mistook His Wife for a Hat tells the stories of individuals afflicted with fantastic perceptual and intellectual aberrations: patients who have lost their memories and with them the greater part of their pasts; who are no longer able to recognize people and common objects; who are stricken with violent tics and grimaces or who shout involuntary obscenities; whose limbs have become alien; who have been dismissed as retarded yet are gifted with uncanny artistic or mathematical talents.
If inconceivably strange, these brilliant tales remain, in Dr. Sacks's splendid and sympathetic telling, deeply human. They are studies of life struggling against incredible adversity, and they enable us to enter the world of the neurologically impaired, to imagine with our hearts what it must be to live and feel as they do. A great healer, Sacks never loses sight of medicine's ultimate responsibility: "the suffering, afflicted, fighting human subject."

some knowledgesomething is missing
[Fabien Gandon 2009]
semantic web technologies make this knowledge explicit
http URI for naming and connecting everything
documents, people, services, organizations, things, places, concepts, brands, etc.
http://...
Triples for simply describing any resource named with a URI
31
ntology for describing knowledgea logical theory which gives an explicit, partial account of a conceptualization i.e. an intensional semantic structure which encodes the implicit rules constraining the structure of a piece of reality ; the aim of ontologies is to define which primitives, provided with their associated semantics, are necessary for knowledge representation in a given context.[Gruber, 1993] [Guarino & Giaretta, 1995] [Bachimont, 2000]

[Fabien Gandon 2009]
e.g. social web ontologies
microformats: ligthweight semantic

By 2012,70% of public Web pages will have some level of semantic markup, but only 20% will use more extensive Semantic Web-based technologies[Finding and Exploiting Value in Semantic Technologies on the Web
Gartner Research Report, May 2007]
[Fabien Gandon 2009]
and now 2012 is pretty close
what's about Gartner's prediction?
e.g. google rich snippets
e.g. facebook open graph protocol

from linked document to linked data
Linked data principles
1.Use URIs as names for things 2.Use HTTP URIs so that people can look
up those names. 3.When someone looks up a URI, provide
useful information, using the standards (RDF, SPARQL)
4. Include links to other URIs. so that they can discover more things.
this is not only a geek or researcher dream!
this is reality!

2010: 24 billion triples!
e.g. data.gov
The Government is releasing public data to help people understand how government works and how policies are made.
There are currently over 4,600 datasets available, from all central government departments and a number of other public sector bodies and local authorities.
This can then be used by people to build useful applications that help society, or investigate how effective policy changes have been over time.
e.g. application
name, describe, and connect
all the world
e.g. 2D tags, QR code, flashcode

e.g. barcode for android
scan these barcodes

the singlemost important thing
I would like you to bear in mind is that…
…you can’t foresee each and every use and reuse
[Fabien gandon 2009]
FREE AND LINK MOST OF YOUR PUBLIC DATA

I'm probably crazy but…
intelligence?“property of the mind including
related abilities, such as the capacities for abstract thought, understanding, communication, reasoning, learning, learning from past experiences, planning, and problem solving”
[wikipedia 2010]
linked data on the web
machine can learn, deduce and exchange knowledge
a social semantic web of things and services
we are teaching the world to machines
a major step forward in artificial intelligence?
aren't we collaboratively teaching machines how to access knowledge, how to create it and how to exploit it?
