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
