Tell me, how much time do you waste searching for stuff on the web, or filling up forms with similar information over and over?
A Scattered Web of Destinations
For all its might, utility, and growth, what we have today is a scattered web, a web of destinations, on which finding information requires a whole expedition across loosely-connected archipelagos of data, each with its own information requirements*, rules of engagement, and gravitational attempts at capturing your time and money.
* I'll get sick if I have to fill one more login form. Even with the advent of Open ID and other unique identity services, way too many applications still require their own sign-in process.
So, when David Siegel contacted me to review his upcoming book Pull: The Power of the Semantic Web to Transform Your Business, I was immediately attracted by his core premise, the creation of a web that would automatically wrap around us and serve us based on the actual characteristics and needs of our lives.
"This book describes the pull era, where customers pull everything to them on demand – products, services, information, knowledge, and advice. Much of the foundation for pulling is called the semantic web, a new way of packaging information to make it much more useful and reusable. Over the next ten to twenty years, it will change business from a lead-push model to a pull-follow model of interacting with customers."
- David Siegel, Pull
Siegel describes the web not as it is, but as we'd like it to be. His vision should be a no-brainer. In the Web-powered world he describes, you would avoid repetitive information tasks and have just the information you need at your fingertip. For many of us, having the web's knowledge organize around us stands right up there with "getting more money" in our Top 5 Desires Chart.
Siegel's vision should be a no-brainer for the web authorities of this world, but it's not.
Offering The Vision We Lacked
Voluntarily or not, by escaping the "Knowledge Curse", Siegel is addressing the main shortcoming of the semantic web development efforts to this day: a vision by techies for techies. The idea of "Turning the Web into a Giant Database" powered by the semantic web stack is at the core of Tim Berners-Lee and the W3C's effort so far at formulating the next web. It's not wrong, but it's not user-centric and it remains a very incomplete vision of what is required to deliver a vastly more useful web.
To get there, the W3C approach really has been to apply the concept of Relational Database to the whole web, throwing in some innovations with RDF and OWL standards and then developing SPARQL on top (the equivalent of SQL in RDBMS). And now only, they are starting to really think about the Proof and Trust levels of the stack. This is putting the cart before the horse.
Certainly illustrations and even applications have been offered (see a recent effort by Talis with the video The Semantic Web and Linked Data – In Action), and there are benefits, but by and large those fall vastly short of what users need and what they hope for, because quite simply those benefits stem from a largely clustered and technologically-centric perspective - and from organizations like the W3C with few people truly thinking in more end user-centric terms.
Because of this, the stack is a castle of cards: it is built on shaky foundations because little attention was paid to how the whole structure should look like and what it should do in the end. So it's overbuilt on some aspects (e.g. turning supergranular pieces of information into triples) and underthought on many others (e.g. origination, trust, speed of querying a web at large, tagging more conceptual pieces of information, timestamping etc). Seconding recent words by Alex Iskold, I will thus predict for 2010 that the "Semantic Web as described in the original vision is still not happening and Linked Data is not unfolding as quickly as some people have predicted."
It's sometimes ok to figure out some of those things as we go, but then we need at least a vision of where we want to be. As the adage says, if you don't know where you're going, any way will get you there. If the vision is to turn the web into a Relational Database as we know them, then that's what we'll get, with all the shortcomings alluded to above.
So, inspired by Siegel, I would propose that the vision and Ariadne's thread of the Semantic effort should be to enable a User-Centric Web.
Product Requirements for the User-Centric Web
To go from the web we have to the web we want, the first step is not to look at the existing technologies and wonder where to go from here, but to identify the unmet needs of end users - and by end users, I don't mean people who build the web, but people who use it for real-world purposes.
The antidote to geek's myopia is to understand the desired benefits, starting with the end in mind, and only then figure what we have and what we lack. If you do a poor job of the first phase, anything you do in the second one is unlikely to amount to much.
What's most to like about Siegel's book is that it does just that: it starts from the needs and hopes of end users, and thus can help us reverse-engineer the "product requirements" for any next-web application.
The most controversial thing about Pull is David's use of the expression Semantic Web in a very different manner from the one. To many, this will look as an attempt to surf the "Semantic wave" for the author's own benefit, and in fact I have no doubt it partially is, given that surfing on trends is pretty much the only way to sell a book concept to a publisher these days. But it is not just that.
His definition of the Semantic Web is one I have long advocated on this blog: a broad one. If it furthers the understanding of data by machine ("semantic") and it links in and out ("web"), it's part of the semantic web. Ok, for the "semantic" part, Siegel also adds a more utopian requirement that "it needs to be tagged in a royalty-free format, governed by a nonprofit organization, that all software programs can understand". We'll see whether the nonprofit part of this vision becomes true, but overall it sounds like the right direction.
Pull does an impressive job of pulling together a number of trends around one common wish. It truly is the book that was missing from our landscape, to articulate the benefits of semantic technologies to businesses and society. This is recommended reading to all builders and users of the next web, and by that I mean anyone with a web access. We have the right vision now, so let's get to work to realize it.
