Rule Certainty Factors

Premise:


($AND (SAME CNTXT SITE BLOOD) 
      (SAME CNTXT GRAM GRAMNEG)
      (SAME CNTXT MORPH ROD) 
      (SAME CNTXT BURNED))
Action:

 (CONCLUDE CNTXT
           IDENTITY PSEUDOMONAS-AERUGINOSA
           TALLY 400)

The result of the rule as a whole is calculated as follows:

  1. $AND sets the global variable TALLY to the minimum CF of its components.
  2. The Rule CF is TALLY times the CF specified in the CONCLUDE line, divided by 1000.
This forms the input to the CF Combination algorithm.
