- I would suggest using a BlackBoard system to do the arbitration.
- You may want to look at HearSay II for inspiration. Alternatively,
- you could try a connectionist approach to the arbitration problem.
- I do not know of anyone who has done previous work with the
- connectionist approach, but would like to hear any ideas. I have
- been thinking about doing something similar to what you have
- suggested for my PhD research, which I hope to start next fall.
