A Knowledge Based Look

A Knowledge Based Look at Federation Conceptual
Model Development Cuneyd FIRAT
2
Motivation

• To explore the types of knowledge common to
  federation conceptual model development
• Emphasizing the knowledge view of federation
  conceptual model development will help to perform
  it consistently

3
Conceptual Modeling

• Conceptual Modeling (CM) is an effort to
  formalize and structure informal requirements
  into a formal blueprint for system developers
• It is an effort to formalize and structure the
  knowledge about a specific system to be developed
  by exploiting methodology knowledge that is about
  interpretation and representation techniques

4
Knowledge!!!

• Knowledge is defined as
• The sum of what is known the body of truth,
  information, and principles acquired by mankind
• Webster Dictionary

5
Knowledge!!!

• Knowledge engineering forms the heart of
  simulation conceptual model
• Dale K. Pace

6
Knowledge for Federation Conceptual Model

• Federation Knowledge (FK) the information to be
  managed and modeled
• Even it is application specific, content of FK
  can be abstracted out for a typical federation
  development

7
Knowledge for Federation Conceptual Model (cont'd)

• Methodology Knowledge (MK) used in managing the
  federation knowledge
• With its well-known and unique techniques, is
  independent of any federation.

Methodology Knowledge

• Requirements Interpretation and Formalization
  Knowledge
• Natural Language Processing Knowledge
• Semantics
• Syntax
• Pragmatics
• Grammar
• Formalization Techniques Knowledge (Artificial
  Languages)

Results

• A taxonomy of the knowledge typical to federation
  conceptual model is given
• As the knowledge content of federation conceptual
  models are identified and elaborated, the concept
  will be clearer and convenience will increase
• Knowledge content will enlighten Federation CM
