Blackboarding is A process that involves experts work together to solve a specific problem using the blackboard as their workspace

Summary

One paragaph which summarises the main ideas of the article.

Description 1

• In this case, the experts work together to solve a specific problem using the blackboard as their workspace;
• Each expert gets equal opportunity to contribute to the solution via the blackboard;
• It is assumed that all participants are experts, but they might have acquired their individual expertise in situations different from those of the other experts in the group;
• The process of blackboarding continues till the solution has been reached;
• Characteristics of blackboard system:
  • Diverse approaches to problem-solving;
  • Common language for interaction;
  • Efficient storage of information;
  • Flexible representation of information;
  • Iterative approach to problem-solving;
  • Organized participation.
• Components of blackboard system:
  • The knowledge source (KS): Each KS is an independent expert observing the status of the blackboard and trying to contribute a higher level partial solution based on the knowledge it has and how well such knowledge applies to the current blackboard state;
  • The blackboard: it is a global memory structure, a database, or a repository that can store all partial solutions and other necessary data that are presently in various stages of completion;
  • A control mechanism: it coordinates the pattern and flow of the problem solution.
• The inference engine and the knowledge base are part of the blackboard system;
• This approach is useful in case of situations involving multiple expertise, diverse knowledge representations, or situations involving uncertain knowledge representation.
