IMPROVED BLACKBOARD

Blackboard Systems

Blackboard systems are not new technology. The first blackboard system, the Hearsay-II speech understanding system [1], was developed nearly twenty years ago. While the basic features of Hearsay-II remain in today’s blackboard systems, numerous advances and enhancements have been made as a result of experience gained in using blackboard systems in widely varying application areas. Unlike most A...

Applying NAILS to Blackboard

Reputation blackboard systems

Blackboard systems are motivated by the popular view of task forces as brainstorming groups in which specialists write promising ideas to solve a problem in a central blackboard. Here we study a minimal model of blackboard system designed to solve cryptarithmetic puzzles, where hints are posted anonymously on a public display (standard blackboard) or are posted together with information about t...

DARBS: A Distributed Blackboard System

Prior to this work, an algorithmic and rule-based blackboard system (ARBS) had been developed over a ten-year period. ARBS benefited from a versatile rule structure and the ability to mix computational styles either as separate knowledgesources or by embedding algorithms within rules. It was a serial system – any knowledge source that was able to contribute had to wait its turn. We report here ...
