PubMed Central ready for the Semantic Web and Open Data?

Ukpmc-Logo

With a background in archaeology, the collections of the Archaeology Data Service tend to be rather more intelligible to me than the underpinnings of advancement in the life sciences that are the bread and butter of PubMed Central and its UK manifestation. I don’t need to be able to engage at a detailed level with all of the science to have long been able to see the importance and value of the initiative, or to see it as an important plank in wider open access and open data activities that I do understand.

As such, it was intriguing to return to decent network connectivity and pick up Matt Day’s post to Nature’s Nascent blog earlier this week;

“What do UK researchers want from UKPMC, their free archive of full-text journal articles? That was the subject of a meeting today at the Wellcome Trust in London.”

Matt mentions that UKPMC are surveying anyone with something to say, asking that we,

“please help [UKPMC] create the definitive portal for biomedical and health research literature”

The online survey is only available until the end of this week, but anyone adding contact details to their submission will be entered into a prize draw to win a weekend in London. There’s no small print, so I can’t tell you whether that prize will include the return flights from Auckland, San Francisco or Beijing… but I suspect not.

We’ve talked about open access publishing, and the publishing-specific requirements of open data, here before. Peter Murray-Rust’s podcast from last year is a good introduction to the area, and it would be a significant step ‘just’ to have some of his quite reasonable requests implemented more widely. Since that podcast, of course, we do now have a licensing framework that has scientific research as one of its intended use cases. UKPMC, the Wellcome, JISC, and others should certainly be looking at that, and giving far more serious thought to the ways in which the core data behind scientific advancement can be at least as addressable as the academic papers they’re investing so heavily in making openly accessible.

Returning to the survey, and Matt’s notes from the meeting, I was interested to see frequent mention of ‘Web 2.0 community participation;’

“Discussion groups then pondered the question about priorities for further UKPMC development. Three broad areas were put forward to focus us all: adding in Web 2.0 community participation, adding in new content types, and adding in new user services.”

Participation is certainly an important step forward, especially in a process that is as participative as science. My immediate impression, though (and I admit that I haven’t seen Timo Hannay’s slides yet) is that I’d question the real value to science or scientists of ‘community participation’ inside yet another silo.

We’re very good at carving the world up, and expecting people to interact in very different ways across the little pockets of functionality that each new web site offers. Yet another username and password. Yet another user interface. Yet another set of ‘friends’ to find, invite, and nurture. Yet another great site that you don’t use enough, because it’s too much hassle to recreate yourself and your network there.

Rather than ’simply’ bolt some tags, curvy-edged boxes, and other Web 2.0 frippery onto the outside of a repository, why not think more radically? Why not throw the whole thing open, leverage the power of the Semantic Web that solutions like the Talis Platform offer, and see what we can do to maximise the value of those connections between papers, people, and areas of research… rather than simply expecting people to restate them, yet again, for some half-purpose?

Most of the data already exist. The technology already exists. Let’s join the pieces together, and do something really interesting.

And, in related news, it’s great to see Richard Poynder writing in ComputerWeekly about some of the work Peter Murray-Rust has been putting in on open access and open data.

More Semantic Web coverage out in venture capital land

46949214 9B03Df39F4 M

Following a flurry of venture capital interest around Metaweb’s announcement of a $42.5 million Series B led by Goldman Sachs earlier this month, it was great to see Troy Lane Williams’ PeoplePad attract VentureBeat’s attention this week.

I have to note, of course, that we got there first:-)

Well done, Troy.

Too much to read, too little time

Weaving the Web cover

Last week, I wrote about Nick Carr’s new book on ZDNet’s Web 2.0 Explorer blog.

I got home last night to find a note from the Post Office confirming that the anticipated Amazon parcel had arrived. Also waiting for me were three editions of the Financial Times, this month’s Wired and this month’s Harvard Business Review.

I’m still reading last month’s HBR! :-( And I need to reread Weaving the Web before next week. Hmm… clearly time to stop sleeping or something.

What is it with all this Library stuff?

Talis is starting to get quite a reputation as a thought leader and innovator in the Semantic Web space. What with being featured as one of the 10 Semantic Apps to Watch on ReadWriteWeb, and everything. A quick glance through that list soon highlights that Talis is different type of company. Different to the start-ups behind most of the applications and developments in this space. Talis is nearly 40 years old.

At first glance, taking an excursion around the Applications area of www.talis.com, or reading the posts on our sister blog Panlibus, or listening to the many podcasts hosted by myself that are published there, you could be forgiven for thinking that all we did was sell software and systems to Public and University Libraries.

So what is this old library company up to with their Semantic Web based Platform? A question that Microsoft Evangelist Jon Udell probed, when he interviewed me for his Interviews with Innovators series on IT Conversations. Worth a listen, as you will see how our thinking has evolved from some of the challenges to be found in the metadata rich world of libraries.

In November I gave a presentation at the Talis Insight Conference. This conference was for library professionals in the UK, they were interested in what we were doing with Platforms & Semantic Web, and how it could be relevant to libraries. Placing the library technology world in context against the background of the waves of technology in the wider world of the web, it helped the understanding of the future benefits that this work will bring in to the library technology sphere. Take a look, you might find it interesting.

With a long history working with rich metadata, it is clear that libraries are fertile grounds for identifying problems that Semantic Web technologies could help solve. For instance by evolving librarian’s cataloging practices to embrace RDF, some of their unfulfilled ambitions, in the area of simply linking together authors and their works, could be realised.

SemanticMarc Three of my colleagues (Rob Styles, Danny Ayers, and Nadeem Shabir) have published a paper Semantic Marc, MARC21 and the Semantic Web [pdf] on Rob’s blog. This paper takes you through the process of translating MARC21 [the lingua franca of library metadata]records directly in to RDF, then building on that basic RDF representation in to a more readable form and then on in to identifying and walking the graph of relationships between authors, their pseudonyms and their books. A very readable and enlightening paper, well worth a read.

So, hopefully having browsed through that lot you will have a better idea why a library company with a nearly 40 year long heritage is actively engaging with Semantic Web stuff - because libraries provide concrete examples, lots of rich metadata that many want to link to.

Libraries have given us an insight in to issues to be found when dealing with large quantities of rich and variable data and metadata - no wonder we are so at home with the Semantic Web.

Polishing that SPARQL, so you can all see it shine

I wrote last week, to draw readers’ attention to the news that SPARQL had reached the dizzy heights of ‘Recommendation’; the highest accolade that those guardians of the web’s evolution, W3C, can award to a technology, and the closest that the group comes to calling anything ’standard’.

SPARQL is definitely extremely important. Indeed, Tim Berners-Lee went so far as to suggest that;

“Trying to use the Semantic Web without SPARQL is like trying to use a relational database without SQL.”

However, it’s one of those pieces of the puzzle that just gets on and does its job, behind the scenes, often unnoticed and unremarked. That is, of course, exactly as it should be. Technology (unless it’s an iPhone) isn’t there to be drooled over. It isn’t there to rub your nose in its cleverness. It should just ensure, quietly, that your task is completed with less fuss, less intervention, and less hassle than before. If you’re lucky, it might let you do something you couldn’t do before.

Reduced to its simplest, the SPARQL Recommendations offer a simple and standard means of querying any store of RDF, regardless of the software used to run the store. The software has to support SPARQL, of course, and the Talis Platform is amongst those that do.

I reckon about 50% of Nodalities‘ readership knows all this, and lobs SPARQL queries about with gay abandon. For the rest of us, seeing is often an important step toward believing, and luckily I know just the man to help.

My colleague, Danny Ayers, has put together a simple demonstration to illustrate how SPARQL queries can be formed and submitted to one of several Talis Platform stores. As the Semantic Web grows, and reaches increasingly beyond the laboratory and the Intranet to embrace the open Web, the ability to consistently and reliably query disparate pools of data via SPARQL will become ever more important. Any resource becomes - potentially - both directly addressable and consistently queryable. A very different picture from that of today’s web… where often all you can search for across the Web at large is the user interface of some proprietary database or other. You then need to visit that database, understand its interface, and then ask the question again; this time constrained to the pool of possible answers within that one source.

Take a look at Danny’s examples (including one for the Twitter store he built for his article in this month’s Talis Platform News) and you begin to understand some of what’s possible. Now stretch a bit, and imagine this query capability transposed behind the shiny, curvy-cornered UI of some Web 2.0 application. Suddenly, this application breaks free of the limitations of its own ‘database’, and is able to reach out across the Web at large to interact with conformant and permissive agglomerations of data, wherever they may be.

See? Told you SPARQL was important.

Update: Leigh Dodds reminds me of his paper at XTech 2006, which also provides useful illustrative examples.

Welcome to SPARQL

Sw-Sparql-Blue

W3C reports that;

“Today, the World Wide Web Consortium made it easier to share and reuse data across application, enterprise, and community boundaries with the publication of three new Semantic Web standards for SPARQL (pronounced ’sparkle’). SPARQL is the query language for the Semantic Web (see Semantic Web use cases). SPARQL queries hide the details of data management, which lowers costs and increases robustness of data integration on the Web. ‘Trying to use the Semantic Web without SPARQL is like trying to use a relational database without SQL,’ explained Tim Berners-Lee, W3C Director. There are already 14 implementations of the standard, which is comprised of three W3C Recommendations: SPARQL Query Language for RDF, SPARQL Protocol for RDF, and SPARQL Query Results XML Format. Read the press release, testimonials and learn more about the Semantic Web Activity.”

A fuller press release is available here.

As our very own Ian Davis noted in his testimonial,

“Talis is delighted to see the publication of the SPARQL Recommendations. We believe that this is an important milestone in making the Semantic Web usable for a broad class of applications in the enterprise. The Talis Semantic Web Platform provides its users with services using the SPARQL query language and protocol to allow searching of their data. We look forward to SPARQL being incorporated in many more applications enabling Web-scale integration of data between and within organisations.”

Welcome to the world, SPARQL!

BlogTalk 2008

Blogtalk2008 Small

I received some good news over the weekend; my submission to BlogTalk 2008 in Cork has been accepted.

I like Ireland, although I’ve not made it to Cork before. It’s always good when this job takes you places you want to go… rather than simply lowering you into the depressing horror that is London as previous jobs of mine tended to do.

Confirmed Keynotes include Yahoo!’s Salim Ismail and Talis Platform Advisory Group member Nova Spivack, so there’s plenty to see alongside my sojourn into ‘Realising potential in the Web of Relationships.’

See you in Cork in March!
