Summary
One paragraph which summarises the main ideas of the article.
Description
- 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.
