The Internet at large
The graph data in this particular example depicts Internet topology showing 535,000-odd Internet nodes and over 600,000 links.

Internet nowadays is not just machines…
• Systems become more interconnected
• Humans and Industrial processes are included in ICT architectures
• Architects are less able to anticipate and design interactions between the components
• Systems becomes too massive for even most skilled system engineers to install configure, optimize, maintain and merge the systems
• And all this may lead..
The last computer genious is theatened!
The latest catastrophe in Japan: Partially fault of an operator
AND WHAT IF HE IS NOT AS HARD??
Global Understanding Environment
• An ICT system which manages itself given high level objectives from the administrator
• A distributed service oriented middleware that supports system components and their interactions
• A system component (or an element) to manage is a resource which delivers services:
• A real world objects connected to a global ICT system (E-utility);• Application service;• An entire business.
Global Understanding Environment
• A component is responsible for: • managing its own internal state and behavior;• managing its interactions within an environment (through signals
and messages to and from other components) and the external world.
• A system manager should only specify what is desired and not how to achieve it.
Engineering/scientific challenges
• How to design diverse (manageable) components?• How to monitor elements and determine problems?
• Event correlation in time / context.• How to maintain relationships among the components?
• Associate the component with a set of output services, which it performs and a set of input services that it requires expressed in a standard format.
• What programming tools and techniques are needed to aid in managing relationships with other components?
• How to locate input services?• Involving sophisticated reasoning about service ontologies.
The dissertation is about…
How to design diverse (manageable) components?
• Agents, Adapters, Ontonuts, Middleware
• The dissertation of Sergiy Nikitin further develops an architecture of Global Understanding environment
• Shows feasibility of the GUN vision in industrial applications through pilot implementations
The dissertation is about…
• How to monitor elements and determine problems?• Event correlation in time / context.
RDFOWL
XML
Ontologies
• The dissertation of Sergiy Nikitin further develops an extension to RDF for managing temporal and contextual binding of components’ information
• Suggests a technique to perform contextual queries using standard tools
The dissertation is about…
• How to maintain relationships among the components?• Associate the component with a set of output
services, which it performs and a set of input services that it requires expressed in a standard format.
• What programming tools and techniques are needed to aid in managing relationships with other components?
• The dissertation of Sergiy Nikitin defines a semantical support and an architectural extension to the agent technology named Ontonuts.
• Ontonut is a semantic software components for representing and managing the agent’s capabilities.
The dissertation is about…
• How to locate input services?• Involving sophisticated reasoning about service ontologies.
• The dissertation of Sergiy Nikitin provides and in an in-depth analysis of the matchmaking problem when querying web services.
Overall, the dissertation of Sergiy Nikitin…
• A conceptual work supported by several practical implementations
• Addresses a set of challenging problems for future ICT architecture
• Demonstrates the feasibility of application of the Global Understanding Environment in the industrial context
• Contributes to the knowledge in the area of autonomic computing in general and Semantic Web in particular
