Semantic Web travel services on a voyage of discovery

05.01.2006


A secure, semantic-based interoperability framework for exploiting Web service platforms across peer-to-peer networks in the tourism industry hopes to set free the valuable Web-based tourism information that is currently trapped in isolated silos of incompatible databases.



"The tourism industry today is the second largest economic sector, after manufacturing, in the world," says Professor Asuman Dogac, Director of the Software Research & Development Center in Turkey, and coordinator of the SATINE project. "Earlier than in other sectors, tourism embarked on e-business, not only with respect to business-to-business, but also with business-to-consumer."

Currently, travel information services are dominantly provided by Global Distribution Systems (GDSs). A GDS gives its subscribers pricing and availability information for multiple travel products such as flights. Travel agents, corporate travel departments, and even Internet travel services, subscribe to one or more GDS’.


"However, small and medium-sized enterprises [SMEs], for example bed-and-breakfast accommodation or companies hiring bicycles, restaurants and many others cannot participate in GDS-based e-business because selling their products through GDS’ is too expensive for them," says Dr Dogac.

Furthermore, GDSs are legacy systems, and suffer from a number of problems. They mostly rely on private networks, are mainly for human use, are difficult to use and have cryptic interfaces. Their speed and search capabilities are limited. Finally, it’s difficult to get them to interoperate with other systems and data sources. This means that tour operators, travel agencies and others cannot benefit fully from the advantages of electronic business-to-business trading.

The potential for advanced online travel Web services

The SATINE project developed a secure peer-to-peer network that enables peers to deploy their semantically-enriched travel Web services and allows others to discover these services semantically. "By introducing semantics to Web services, we have addressed the interoperability issue on the semantic level and constructed a peer-to-peer network that eases service discovery," says Dr Dogac.

"The creation of complex services through the orchestration of simple Web services is an important task that is of particular relevance in the travel business: Apart from the typical examples, like the composition of package tours, more sophisticated services like a flight booking based on the availability of tickets for a certain cultural event are conceivable," says Dr Dogac.

For instance, ultimately the work of SATINE could lead to very advanced travel services, where a holiday maker might enter terms like the dates, cost, car rental, hill walking, scuba diving and sunbathing and then be presented with a list of options offering all those activities and services with detailed itineraries and cost information, and all necessary bookings. The user would simply click on the option that appeals most.

"In SATINE project, we have developed a Semantic Wrapper for constructing and describing Web services," says Dr Dogac. The main role of this component is to wrap existing information resources to make them appear as semantically well-described Web Services. It’s an easy-to-use tool for SMEs to create and annotate Web services from their existing enterprise applications.

The Semantic Wrapper provides two complementary tools: the Web Service Creator and the Web Service Annotator. The Web Service Creator transforms existing resources in Web Services. The Web Service Annotator describes a Web service at a semantic level, using OWL-S as the ontology of reference.

OWL is a markup language for publishing and sharing data using ontologies on the Web. OWL-S ontologies describe the Web service semantics. Ontologies are the vocabularies that allow machines to identify specific services or information. For example, a human operator would understand the term ’booking’, but it needs to be defined in a special way for a machine to understand.

The project is also developing a mobile application to wrap the basic functionality of SATINE and provide a mobile interface for consumers to query and invoke the services in the network. These are secure Web services deployed among peers in the p2p network.

The project developed a prototype that was demonstrated successfully at over six major conferences. SATINE also organised a number of commercial demonstrations, including one to German software firm, SAP research.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
