The semantic web
“I have a dream for the Web [in which computers] become capable of analyzing all the data on the Web – the content, links, and transactions between people and computers.
A ‘Semantic Web’, which should make this possible, has yet to emerge, but when it does, the day-to-day mechanisms of trade, bureaucracy and our daily lives will be handled by machines talking to machines.
The ‘intelligent agents’ people have touted for ages will finally materialize.”
Sir Tim Berners-Lee, inventor of the World Wide Web 1999

The semantic web
Mostly flat information
Some databases but content very functional
Little engagement or
interactivity
![Page 4: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/4.jpg)
The semantic web
Greater interactivity
Growth of social media /
social networking
Online communities
created / social capital
![Page 5: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/5.jpg)
The semantic web
Joining up of information
Data portability
Browsers and search
engines become more
‘intelligent’
![Page 6: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/6.jpg)
The semantic web
Works but is clunky, not that efficient, technically limited
![Page 7: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/7.jpg)
The semantic web
Smoother experience, looks better, still lacks cohesion
![Page 8: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/8.jpg)
The semantic web
Greater scope for exploration, limitless potential, smart
![Page 9: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/9.jpg)
The semantic web
![Page 10: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/10.jpg)
The semantic web
OK, so we’ve seen how the web is evolving.
Let’s get into semantics.
Firstly, we’ll look at the traditional web model…
![Page 11: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/11.jpg)
The semantic web
Let’s introduce Professor
Gibson.
With the traditional web
model she has the
following…
![Page 12: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/12.jpg)
The semantic web
A faculty page
![Page 13: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/13.jpg)
The semantic web
A faculty page
A research page
![Page 14: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/14.jpg)
The semantic web
A faculty page
A research page
A blog
![Page 15: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/15.jpg)
The semantic web
A faculty page
A research page
A blog
and a staff listing page
![Page 16: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/16.jpg)
The semantic web
The content of these
sites is fine but there are
no linkages between the
data.
So visitors find it
difficult to get all the
information they need
quickly and easily.
![Page 17: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/17.jpg)
The semantic web
That’s where the
Semantic web comes in…
![Page 18: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/18.jpg)
The semantic web
Using code we can create
relationships between
websites, people and
events…
These can then be
understood by the browser
and interpreted in a helpful
way.
![Page 19: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/19.jpg)
The semantic web
So we can link Professor
Gibson’s faculty page to
her research.
![Page 20: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/20.jpg)
The semantic web
So we can link Professor
Gibson’s faculty page to
her research.
Then link data in her blog
to both of these.
![Page 21: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/21.jpg)
The semantic web
So we can link Professor
Gibson’s faculty page to
her research.
Then link data in her blog
to both of these.
And link profile data to
her staff listing.
![Page 22: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/22.jpg)
The semantic web
And her staff listing could
show some of the other
academics she works with.
![Page 23: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/23.jpg)
The semantic web
And her staff listing could
show some of the other
academics she works with.
With her research page
showing her links with
worldwide research
collaborators.
![Page 24: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/24.jpg)
The semantic web
Who also know one of
her colleagues.
![Page 25: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/25.jpg)
The semantic web
Who also know one of
her colleagues.
Who comment on
Professor Gibson’s blog
regularly.
![Page 26: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/26.jpg)
The semantic web
With all this data being
able to be displayed
simply it provides a much
richer user experience and
offers information that
previously might not have
been exposed.
![Page 27: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/27.jpg)
The semantic web
Well that’s exciting stuff. But how do we go about
getting onboard with semantics?
Glad you asked. There are a few different ways we’ll
look at in more detail now…
![Page 28: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/28.jpg)
The semantic web
Firstly we could create
Our documents using
RDF:
ResourceDescriptionFramework
![Page 29: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/29.jpg)
The semantic web
Here special meta-data
code is added to pages
that describe the
relationships between
that data.
These are called triples.
![Page 30: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/30.jpg)
The semantic web
RDF is very powerful but
up to now hasn’t been
widely deployed as it
can be a very complex
process to create the
relationships and
browser support has been
limited.
![Page 31: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/31.jpg)
The semantic web
Having said this, better
tools now exist to
create RDF documents
which we will explore in
the next section.
![Page 32: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/32.jpg)
The semantic web
An easier way of getting
involved is to use
Microformats.
These are simple pieces
of code that allow the
browser to interpret the
data intelligently.
![Page 33: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/33.jpg)
The semantic web
Here’s a couple of real
world examples from
some of our pages…
![Page 34: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/34.jpg)
The semantic web
On the communications
team website the address
has been coded as a
microformat.
![Page 35: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/35.jpg)

The semantic web
On the communications
team website the address
has been coded as a
microformat.
This allows the visitor to
automatically add the
contact details to Outlook.
![Page 37: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/37.jpg)

The semantic web
Now let’s take a look at
the HR contacts page.
Again we’ve used the
address microformat.
![Page 39: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/39.jpg)
The semantic web
Now let’s take a look at
the HR contacts page.
Again we’ve used the
address microformat.
This allows visitors to get
a Google map of the
location with a single click.
![Page 40: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/40.jpg)

The semantic web
Let’s now take a look at some of the options available to us if we want to take things forward…
![Page 42: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/42.jpg)

The semantic web
Jadu is the CMS we are
using for the corporate
web project.
![Page 44: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/44.jpg)
The semantic web
Jadu is the CMS we are
using for the corporate
web project.
It already provides rich
metadata functionality
when building pages.
![Page 45: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/45.jpg)
The semantic web
They have made it clear
that semantic web tools
are part of their product
road map and are in the
pipeline.
We have discussed this
with CEO Suraj Kika
previously.
![Page 46: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/46.jpg)
The semantic web
He also states on the
Jadu website:
"For information on the
Internet to make sense to
people and to machines –
its necessary to adopt
standards as and when
they change"
![Page 47: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/47.jpg)
The semantic web
Benefits of using Jadu
We already have the
system running.
Training costs are greatly
reduced.
Jadu works well with our
Google search engine.
![Page 48: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/48.jpg)
The semantic web
Benefits of using Jadu
All the code created is
accessible and fully
standards compliant.
![Page 49: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/49.jpg)
The semantic web
Drawbacks of using
Jadu
We may need some
functionality that doesn’t
yet exist and needs to be
developed.
![Page 50: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/50.jpg)

The semantic web
Drawbacks of using
Endeca
Creates additional
complexity in page builds
so more to go wrong and
timescales affected.
![Page 54: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/54.jpg)
The semantic web
Open Calais is a project
funded by Reuters to
help improve the quality
of web metadata.
A key element of this is
a set of powerful tools for
creating RDF documents
and semantic applications.
![Page 55: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/55.jpg)

The semantic web
Benefits of using Open
Calais
Could probably be made
to work with Jadu and
other sites fairly easily.
![Page 57: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/57.jpg)
The semantic web
Drawbacks of using
Open Calais
No guarantees the service
will always be free.
![Page 58: The semantic web or how I learned to stop worrying and love metadata… Richard Ashby, communications team 5 August 2008.](https://reader036.fdocuments.in/reader036/viewer/2022070406/56649e005503460f94ae98e4/html5/thumbnails/58.jpg)
The semantic web
We’ve already looked at
microformats but let’s
now see the pros and
cons of using them.

The semantic web
Benefits of using
microformats
Very simple to add to
pages.
Code is easy to follow, and
more ‘human friendly’ than
RDF.

The semantic web
Benefits of using
microformats
Flexible and can be put
to many different uses.
Require very little time /
money investment.

The semantic web
Drawbacks of using
microformats
Lack some of the power
of RDF.
Browser support is still
somewhat patchy.

The semantic web
Recommendations
Continue to use
microformats.
Liaise with Jadu to see
how CMS can help deliver
semantic data.

The semantic web
Recommendations
Potentially some more
research on Endeca to
see if any benefits can be
derived.
Investigate if Open Calais
could provide any quick
wins.

The semantic web
We’ve covered quite a lot of ground to this point.
Now there will be a practical demonstration of the
semantic web in action.
Thanks for listening.
