Blackboard system
A blackboard system is an artificial intelligence approach based on the blackboard architectural model, where a common knowledge base, the" blackboard", is iteratively updated by a diverse group of specialist knowledge sources, starting with a problem specification and ending with a solution.
Each knowledge source updates the blackboard with a partial solution when its internal constraints match the blackboard state.
In this way, the specialists work together to solve the problem.
The blackboard model was originally designed as a way to handle complex, ill- defined problems, where the solution is the sum of its parts.
