More and more data on the internet is being published in reusable and
remotely queryable formats. Some of us may be familiar with XML which
is way of structuring data so it can be interpreted by a variety of
different applications and devices – for example RSS feeds are
specified using XML
To make this really clear – here is an example:
We
all have a common understanding of the concept of “a book”. We
understand that are several elements to a book: it has an author, a
publisher, a title and so on. So we have a common shared frame of
reference for how we define a book.
However to a computer the
concept of ‘a book’ is meaningless. What structured data formats such
as XML do is to allow for the creation of common definitions so that,
say, within the publishing industry information can be specified in the
same way and shared easily between companies. So in the XML world a
book can actually be defined as having a title, author, ISBN number,
publisher etc. so that different computer systems and applications all
‘understand’ the definition of a book – and can then manipulate that
data with a common frame of reference.
What this then means is
that intelligent agents or spiders (essentially programs that crawl the
web) can scan different websites, gather data and make valid
comparisons. This is how price comparison sites such as Kelkoo and
Confused.com work.
The next evolution of this is called the
Semantic Web. “Semantics” is about the meanings of things and the
Semantic web is described as a state of the internet where computers
can not only recognise and compare structured data – but be able to
actually understand how different pieces of information relate to each
other.
“The Semantic Web describes the relationships between
things (like A is a part of B and Y is a member of Z)…and the
properties of things (like size, weight, age and price)” (source
w3schools.com)
This moves us towards the vision of the web
originally envisaged by its creator Tim Berners-Lee as a universal
medium for data, information and knowledge exchange.
Back in 1999 he said:
“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”
And
even though a statement made a decade ago appears prehistoric by
today’s fast moving standards, elements of this vision are taking shape.
The World Wide Web Consortium (W3C)
is the organisation responsible for setting technical standards on the
web. They are examining a series of standards designed to make data as
openly accessible and linkable as possible and in which automated
software can store, exchange, and use machine-readable information
distributed throughout the Web. As a result, this will enable users to
deal with the information with greater efficiency and certainty.
One
element of these standards is called RDF (Resource Description
Framework) and putting information into RDF files makes it possible for
intelligent agents and spiders to search, discover, pick-up, collect,
analyse and process information from all over the internet. In essence
the Semantic Web uses RDF to describe the content and resources on the
internet.
And as all data on the internet becomes part of this
standard format, it transforms the web from a random collection of
pages into one huge database with each piece of data connected to each
other in a way that computers can understand.
So what does that mean for marketers?
Put simply, it means that the internet is going to get organised.
As
search engines start to recognise semantically tagged data in their
pages that they crawl, structured data as per the RDF formats will
present far more compelling summaries of those pages in their search
results.
It’s basically like current search engine marketing –
but on steroids. In fact this aspect is often referred to as Search
Engine Optimisation Plus (SEO+). Search is seen as the killer
application for the Semantic Web that will finally drive its growth.
So
at the most fundamental it means that marketers will need to start
managing brands in the Semantic layer that the consumer cannot see as
actively as they manage their brands in the layers consumers can see –
that’s websites, online advertising etc.
Scott Brinker on the Chief Marketing Technologist Blog suggests that:
“Marketing
becomes champion of the underlying data – good, accurate, detailed
content and the processes by which to keep it up to date. This isn’t
just old school “marketing data” ie the stuff of brochures and the
visual corporate website, but rich, detailed information that’s
historically been trapped much deeper in the organisation – information
that can create value for the firm by its wide disseminations….this
constitutes a new kind of market positioning and placement…semantic
branding if you will”
And having data in a more
accessible format will mean that organisations will look to build rich
data applications over the top of this data.
One example given
by Tim Berners-Lee is of being able to combine your calendar and bank
statements. If both of these talked the same language then a user would
be able to drag their digital bank statements onto their calendar and a
series of dots would appear showing the user when they spent their
money. Now imagine that you still can’t remember where a particular
transaction happened – then you could drag your photo album on top of
your calendar and be reminded that you used your credit card at the
same time you were taking pictures of your kids at a theme park.
And
if we look at comparison or price aggregation sites, with the semantic
web consumers will increasingly be able to make more accurate and
reliable comparisons not just for more complex & configurable
products such as cars, holidays etc, but also services such as
builders, accountants and solicitors because the information on those
products and services can be far richer and more structured.
Let’s
take another example of a consumer searching for a ‘holiday’ in the
future. The Semantic Web will allow people to use these ‘information
agents’ and set them tasks such as “go and find me a holiday” that’s:
• In Greece
• By a beach
• But also has some historical interest
• That fits my calendar
• And fits within my budget
The intelligent agent is then left to in
stantly
research the request, asking additional questions where necessary. An
early example of this is www.tripit.com. With Tripit a user can simply
forward their travel confirmation emails and the site and their Tripit “Itinerator”
takes over and combines all the related travel bookings (from flights,
car hire and hotels) into a single master itinerary. It then searches
the Web to add related information such as daily weather, local maps,
driving directions (for example to get from the airport to the hotel),
city guides and so on. You can then access your itinerary from a mobile
device or synchronise it with your PC calendar and share itineraries
within group bookings to make sure there are no date issues or overlaps.
This
will also be important to B2B marketers where our consumer habits of
online research have been transported into the workplace and where
businesses will need to create and manage their semantic data with
increasing numbers of potential customers using search engines to
research and shortlist suppliers.
Another example of the “Semantic Web” is s
omething called ‘Friend of a Friend’ (FOAF). And this is interesting because of its impact on the future of social networking.
FOAF
allows people to describe themselves using an RDF format. You can
describe personal details, hobbies, relations to other people &
things. But what’s fascinating about FOAF is that there is no one
central database or repository of information. Your profile does not
exist only in Facebook, or Bebo or Myspace. It’s a piece of data
searchable by any computer. Computers may then use these FOAF profiles
to find and relate people to one another.
It’s the 21st Century equivalent of ’6-Degrees of Separation’.
