Concept Slicing

• Programming slicing Concept assignment
• Program slicing
• code analysis technique used to identify and
  abstract the smallest possible subset of a
  program that can perform an expected
  functionality.
• Slicing criterion variables or program points
  (Hard but executable )
• Concept assignment
• assigns individual human-oriented concepts to
  portions of source code.
• Slicing criterion domain level concepts (Easy
  but not executable )
• Concept slicing
• combines PS and CA -gt Executable Concept slices
  (ECS)

Concept Slicing (COBOL program)

• Done manually
• Identify all the variables in the code.
• Write down values and line numbers for all
  variables.
• Evaluate the identified variables.
• Negative concept assignment.
• Apply program slicing on the variables identified
  by the concept assignment process.

• Visualization of source code
• Source code analysis (Functional and data
  dependency)
• SCA-based Migration feasibility

• Conclusion
• What can be reused from the initial related
  projects/works?
• Method fragment of SO development methods
• Code extraction techniques
• How can we improve our techniques of extraction?
• Slicer for other languages like COBOL
• How can we make the extraction language platform
  independent?
• Code query technologies
• Can we use design pattern (architectural) to
  local the potential services in legacy codes?
• Source code analysis for data and functional
  dependency
