The Future Starts Today
“Industrial Ontologies” Group

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
Semantic Web is an extension of the current
web in which information is given well-defined
meaning, better enabling computers and people
to work in cooperation
Agentcities is a global, collaborative effort
to construct an open network of on-line systems
hosting diverse agent based services.
Agentcities
Grid Computing
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.
Web 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.

Web Services
• 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

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

Different companies would be
able to share and use
cooperatively
their
Web
resources and services due to
standardized descriptions of
their resources.
Corporate/Business Hub
Hub ontology
and shared domain ontologies
Partners / Businesses
What parties can do:
Companies would be able to create “Corporate
Hubs”, which would be an excellent cooperative
business environment for their applications.
What parties achieve:
Publish own resource descriptions
Software and data reuse
Advertise own services
Automated access to enterprise (or partners’) resources
Lookup for resources with semantic search
Seamless integration of services
Ontologies will help to glue such Enterprise-wide / Cooperative Semantic Web of shared resources
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…
