Enter the Semantic Grid

02.02.2006


To allow business and people to rapidly, and easily, establish virtual organisations to share information, services and computing resources a team of European researchers are laying the technological foundations that will open the door to the era of the Semantic Grid.

OntoGrid on track for Semantics



Working under the IST programme-funded OntoGrid project, they are catalysing the evolution of the Grid from a distributed network of computers in which the meaning of information is implicit and hidden into a medium that will allow computers as well as humans to interpret and share semantically-enriched data.

The upshot is a technological infrastructure in which semantically-aware middleware allows collections of resources - computing, storage, data sets, digital libraries, scientific instruments, businesses and people – to rapidly come together to form virtual organisations to solve a specific problem and disband just as easily once a solution is found. By overcoming cross-organisational, cross-industry and cross-country boundaries, and increasing interoperability by making semantic assumptions explicit, the Semantic Grid promises to aid organisations and businesses in any field where input from multiple and potentially highly differentiated actors is required.


“What we are doing is enriching the Grid with semantics,” explains Asunción Gómez-Pérez at the Universidad Politécnica de Madrid, and one of the OntoGrid coordinators. “This is a visionary initiative. Few other researchers are working in this area at present.”

To test its highly innovative approach, the project partners are developing two semantic applications to be run over Grid infrastructure. One will consist of an insurance settlement system linking together the various parties involved in resolving insurance claims as a way to reduce costs, increase cross-organisational collaboration and fight fraud. The other will offer quality analysis for satellite images, allowing users to transparently obtain and analyse information from different data centres.

“The insurance settlement system solves a very real problem facing the insurance sector: how to resolve claims in which many very different actors are involved,” notes Carole Goble, the OntoGrid’s technical coordinator at the University of Manchester.

“Imagine you crash a car in Spain that you rented in France with a German-registered car driven by a Dutchman: resolving the paperwork is a major problem,” Goble notes. Similarly, the lack of collaboration and communication mechanisms between insurers and other actors raises the potential for fraud. With a Semantic Grid application a virtual organisation linking all actors involved could rapidly be established to settle the claim using semantically-enriched information to overcome their procedural differences and ensure they all use the same terminology.

Middleware for any context

“The problem with the Grid that has existed to date is that it is rigid, systems aren’t easily configurable and there is no way to do things quickly,” the technical coordinator says. “In OntoGrid we are developing flexible and configurable middleware that can be reused.”

To do so, the project has developed Semantic-OGSA, a reference architecture that represents an evolution of the Open Grid Service Architecture (OGSA) and defines a mechanism for the explicit use of semantics in components and applications.

From a business perspective, the more flexible middleware will allow companies to be more agile in finding solutions to problems as and when the need arises, and is particularly beneficial in sectors where actors are distributed. The Semantic Grid middleware could also easily be connected to existing (legacy) systems.

The enhanced information aggregation and exchange the Semantic Grid provides also offers other benefits. The quality analysis system for satellite images, for example, would help aerospace firms collect different data streams from different organisations that use different processes and aggregate it for different purposes, whether it is weather analysis or crop assessment.

Though adopting Semantic Grid systems today is likely to entail large upfront costs for companies (as the technology is still under development), in Goble’s view it will pay off in terms of increased productivity and lower costs in the long term. But as the technology matures (which is something that OntoGrid is contributing to), the upfront costs should go down by orders of magnitude. And she is confident that such systems will be used widely in the future, probably in part thanks to the groundwork carried out by the OntoGrid researchers.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
