Helping Autism Researchers, And Others, With Some SPARQL Savvy

One in 50 American children have autism, according to the latest figures released by the Centers for Disease Control and Prevention in March. One of the winners of the YarcData Graph Analytics Challenge, announced in April, can make a difference in better understanding the causes of the disease.

Taking second place in the competition, the work of Adam Lugowski, Dr. John Gilbert, and Kevin Dewesse, of the University of California at Santa Barbara, leveraged a dataset created for the Mayo Clinic Smackdown project, that has the same structure and property types – and scale – as the medical organization’s actual Big Data sets around autism, but which uses publicly available data in place of the real thing. The team can’t use the real data because it includes private information about patients, diagnosis, prescriptions, and the like.

But the actual data deployed for the project doesn’t matter, says Lugowski . “The goal is to find relationships we have never thought of before, and this way it doesn’t prejudice the algorithm,” he says. Using YarcData’s uRIKA graph analytics appliance, the algorithm queries the Smackdown dataset – which in its smallest version has almost 40 million RDF triples and in its largest is about 100 times bigger, mirroring the size of all the Mayo Clinic’s actual autism data – to discover commonalities among the data, mimicking how the real data sets could be queried in search of common precursors among clusters of patients with the diagnosis.

UNIT4 and a Push for Open Data Analytics

Pete Swabey of Information Age recently discussed UNIT4, “the Dutch-owned ERP vendor that acquired UK accounting software provider Coda in 2008. The company collaborated with UK semantic web consultancy Epimorphics to develop a platform that allowed customers to expose their data online as SPARQL endpoints, meaning it could be retrieved using SPARQL, the querying language for RDF. The platform was developed with local authorities in mind, facing as they are growing pressure to be transparent. ‘We were hoping we would have an audience of armchair auditors,’ recalls Pete Brown, chief technology officer of UNIT4 UK.” Read more

For The Enterprise IT Set: Steps To Success With Semantic Tech

IT leaders keeping an eye on Gartner’s top tech trends list know that early in March semantic technologies made the cut (see our original story here, and our follow-up with one of the authors of the Gartner report here). The big question for many enterprise IT pros, though, is what should they be doing with that knowledge – how can they start leveraging semantic technology to their own organizations’ benefit?

Help is on the way. Three experts in semantic web technologies and Linked Data weigh in with their advice on heading down that road:

Fujitsu Labs And DERI To Offer Free, Cloud-Based Platform To Store And Query Linked Open Data

The Semantic Web Blog reported last year about a relationship formed between the Digital Enterprise Research Institute (DERI) and Fujitsu Laboratories Ltd. in Japan, focused on a project to build a large-scale RDF store in the cloud capable of processing hundreds of billions of triples. At the time, Dr. Michael Hausenblas, who was then a DERI research fellow, discussed Fujitsu Lab’s research efforts related to the cloud, its huge cloud infrastructure, and its identification of Big Data as an important trend, noting that “Linked Data is involved with answering at least two of the three Big Data questions” – that is, how to deal with volume and variety (velocity is the third).

This week, the DERI and Fujitsu Lab partners have announced a new data storage technology that stores and queries interconnected Linked Open Data, to be available this year, free of charge, on a cloud-based platform. According to a press release about the announcement, the data store technology collects and stores Linked Open Data that is published across the globe, and facilitates search processing through the development of a caching structure that is specifically adapted to LOD.

Dandelion Geo And Linked Data Marketplace Private Beta On The Way

This week Dandelion, which bills itself as the one-stop shop for smart, high-quality Geo and Linked Data from trusted sources, starts its private beta. The service, which promises end users quality, normalized, linked and enriched data for their apps and reports; developers a simple API for any kind of language on any kind of platform; and corporate and government entities a way to publish and profit from their data, comes from SpazioDati.

That company is the creation of four Italian entrepreneurs – CEO Michele Barbera, president Gabriele Antonelli, partnerships director Andrea Di Benedetto, and Luca Pieraccini – who lived first-hand the frustrating experience of trying to find and leverage useful data for the custom web and mobile apps they were developing while running and working in small IT consulting companies. In an attempt to reverse the ratio of finding and cleaning data to actually building apps, says Barbera, the founders began participating in several EU-funded research projects and in the Open Data movement in Europe and Italy, including founding the non-profit Linked Open Data Italy. They also started experimenting with Semantic Web technologies.

“Open Data helps us to find valuable data and to build value-added web and mobile apps,” says Barbera. “So, let’s say that we solved partly the first problem of finding data, but not the second one, normalizing and cleaning data, since it is still very difficult to merge different data sources to put data in context.” Read more

Eleven SPARQL 1.1 Specifications are W3C Recommendations

SPARQL LogoThe W3C has announced that eleven specifications of SPARQL 1.1 have been published as recommendations. SPARQL is the Semantic Web query language.  We caught up with Lee Feigenbaum, VP Marketing & Technology at Cambridge Semantics Inc. to discuss the significance of this announcement. Feigenbaum is a SPARQL expert who currently serves as the Co-Chair of the W3C’s SPARQL Working Group, leading the design of SPARQL.

Feigenbaum says, “SPARQL 1.1 is a huge leap forward in providing a standard way to access and update Semantic Web data. By reaching W3C Recommendation status, Semantic Web developers, vendors, publishers and consumers have a stable, well-vetted, and interoperable set of standards they can rely on for the foreseeable future.”

Music To Your Ears: Seevl Takes First Step To Become Cross-Platform Music Discovery Service

Seevl, the free music discovery service that leverages semantic technology to help users conduct searches across a world of facts-in-combination to find new musical experiences and artist information, has launched an app for Deezer that will formally go live Monday.  (See our in-depth look at Seevl here, and a screencast of how the service works here.) Deezer is a music streaming service available in more than 150 countries – not the U.S. yet, though – that claims more than 20 million users.

Seevl, which late last year updated its YouTube plug-in with more music discovery features and better integration with the YouTube user interface, models its data in RDF. In a blog post earlier this year, founder and CEO Alexandre Passant explained how the Seevl service uses Redis for simple key-value queries and SPARQL for some more complex operations, like recommendations or social network analysis, as well as provenance. As for the new Deezer app, it provides the same features as the YouTube app for easily navigating and discovering music among millions of tracks, Passant tells the Semantic Web Blog.

Forage Through More Than A Century Of Nobel Prize Awards

When the Nobel Prize winners for 2013 are announced in the fall, perhaps there also will be some challenges issued to the worldwide community of data enthusiasts to see what they can do with open Linked Data about the prizes that have been awarded since the beginning of the 20th century.

Right now that’s just on the wish lists of Matthias Palmér and Hannes Ebner, co-founders of MetaSolutions AB, a spin-off from the Royal Institute of Technology in Stockholm and Uppsala University focused on semantic and scalable web apps. But a solid start has been made through their work with Nobel Media AB, which develops and manages programs, productions and media rights of the Nobel Prize within the areas of digital and broadcast media, including the Nobelprize.org domain, on the Nobel Prize Linked Data set.
