  6. Two Approaches for Processing • Neural Networks • Bayesian Conditional Probability • Pros/Cons • Expert Systems • Consolidated Assessment Business Rules • Pros/Cons

  7. Future Challenges / Possible Solutions • Horizontal systems integration • Current systems • Future systems • Satellites • Ground Systems • Most importantly: Same info, different interpretation • Significance of info • How info is handled
