Semantic Web:The Future Starts Today

“Industrial Ontologies” Group

InBCT Project, Agora Center, University of Jyväskylä, 29 April 2003

Industrial Ontologies Group:Important Objective

• For us there are no doubts about the possibilities, which Semantic Web opens for industry.

• that is why one important objective of our activities is to study appropriate industrial cases, collect arguments, launch industrial projects and develop prototypes for the industrial companies to not only believe together with us but also benefit from the Semantic Web.

Why and Where Semantic Web ?

WWW

Business

Knowledge Management

more then 3,000,000,000 web-pages “Information” burst ICT needs comprehensive resource management technology

Needs for integration of businesses Web Services for e-Business Standardization and Interoperability problems

Consolidate and reuse experience Standardize knowledge sharing technology Needs for the intelligent tools to use human’s knowledge

Approach: Semantic Web

“The Semantic Web is a vision: the idea of having data on the Web defined and linked in a way that it can be used by machines not just for display purposes,

but for automation, integration and reuse

of data across various applications”

http://www.w3.org/sw/

The Semantic Web is an initiative with the goal of extending the current Web and facilitating Web automation, universally accessible web resources, and the 'Web of Trust', providing a universally accessible platform that allows data to be shared and processed by automated tools as well as by people.

Word-Wide Correlated Activities

Semantic Web

Grid Computing

Web Services

Agentcities

Agentcities is a global, collaborative effort to construct an open network of on-line systems

hosting diverse agent based services.

WWW is more and more used for application to application communication.The programmatic interfaces made available are referred to as Web services.

The goal of the Web Services Activity is to develop a set of technologies in order to bring Web services to their full potential

FIPA

FIPA is a non-profit organisation aimed at producing standards for the interoperation

of heterogeneous software agents.

Semantic Web is an extension of the currentweb in which information is given well-definedmeaning, better enabling computers and people

to work in cooperation

Wide-area distributed computing, or "grid” technologies, provide the foundation to a number of large-scale efforts

utilizing the global Internet to build distributed computing and communications infrastructures.

Smart machines and devices

• Web services are self-contained, modular business Web applications with open and standardized interfaces.

• Web Services is next-generation technology for EAI, e-Business and industrial automation.

• Unlike e-Commerce, Web Service are supposed to be used not by humans, but by other services or software applications.

• Web Services will be retrievable in the Web, integrated and used by an application in the same way as humans are browsing and accessing web resources.

• Web Services are building blocks for future information systems.

Semantic Web will provide a description framework for Web Services, which is required for automated service discovery and composition

Ontologies are key enabling technology for the Semantic Web

“..explicit specification of conceptualization..”

Ontology is formal and rich way to provide shared and common understanding of a domain, that can be used by people and machines

Applications of Semantic Web

Semantic Web provides a basis for interoperability, scalability, intelligent processing,reuse of resources/knowledge/services

Possible Application Areas:• Global (Internet):

– e-Commerce, Web Services

• (Inter-)Enterprise: – EAI, e-Business

• Industrial (sub)systems: – Process Automation, Condition Monitoring, Maintenance etc.

Machine-to-Machine Communication

P2P ontology

P2P ontology

Heterogeneous machines can “understand” each other while exchanging data due to shared ontologies

Semantic Web-Supported Sharing and Integration of Web Services

Different companies would be able to share and use cooperatively their Web resources and services due to standardized descriptions of their resources.

P2P ontology

P2P ontology

Corporate/Business Hub

Publish own resource descriptions

Advertise own services

Lookup for resources with semantic searchAutomated access to enterprise (or partners’) resources

Hub ontologyand shared domain ontologies

Seamless integration of services

Software and data reuse

Partners / Businesses

What parties can do:What parties achieve:

Ontologies will help to glue such Enterprise-wide / Cooperative Semantic Web of shared resources

Companies would be able to create “Corporate Hubs”, which would be an excellent cooperative business environment for their applications.

Web Services for Smart Devices

Smart industrial devices can be also Web Service “users”. Their embedded agents are able to monitor the state of appropriate device, to communicate and exchange data with another agents. There is a good reason to launch special Web Services for such smart industrial devices to provide necessary online condition monitoring, diagnostics, maintenance support, etc.

Conclusion

• Semantic Web is not only a technology as many used to name it;

• Semantic Web is not only an environment as many naming it now;

• Semantic Web it is a new context within which one should rethink and re-interpret his existing businesses, resources, services, technologies, processes, environments, products etc. to raise them to totally new level of performance…
