Yes, this works! This meets my requirements.

 

Thank you Wolfgang.

 

This is similar to my first effort, which never fires. Can you explain the
difference between the two rules.

 

My first effort

 

(defrule find-lines-per-block-ssn

   ?word1 - (word (page ?page) (rowNumber ?rowNumber1) (type ssn)
(text ?text1)  )

?word2 - (word (page ?page) (rowNumber ?rowNumber2:(
?rowNumber1 ?rowNumber2)) (type ssn) (text ?text2) )

(not 

(word (page ?page) (rowNumber ?rowNumberVar:( (abs (-
?rowNumberVar ?rowNumber1) ) (abs (- ?rowNumber2 ?rowNumber1) ) ) ) )

)

=

; do something

) 

 

Thanks to everyone who responded. This was my first message to the forum.
Thanks for all the quick and helpful responses.

 

Bob

Not sure whether this meets all the possibly undisclosed requirements, not
sure about the relation of row numbers and words, but this is firing one,
even when there is words from more than one page:

(defrule find-lines-per-block-ssn
  ?w1 - (word (page ?page)
   (rowNumber ?rowNumber1)
   (type ssn)
   (text ?text1))
  ?w2 - (word (page ?page)
   (rowNumber ?rowNumber2 :( ?rowNumber1 ?rowNumber2))
   (type ssn)
   (text ?text2))
  (not (and (word (page ?px)
  (rowNumber ?rn1)
  (type ssn))
(word (page ?px)
  (rowNumber ?rn2 :( ?rn1 ?rn2))
  (type ssn))
(test ( (- ?rn2 ?rn1) (- ?rowNumber2 ?rowNumber1)
=
  (printout t (fact-slot-value ?w1 text)  -  (fact-slot-value ?w2 text)
crlf)
)

What makes one word different from another one? Surely *you* know (but
*we*don't), and this must be a constraint in that rule.

If it is the rowNumber, than this condition would be logically correct:
   (rowNumber ?rowNumber2 :( ?rowNumber1 ?rowNumber2))
although it were better written as
   (rowNumber ?rowNumber2  ~?rowNumber1)
If it isn't, omit this constraint.

 rowNumber are integers, 1, 2, 3

 I have verified that there is a single minimum.

 I have tried

 (defrule find-lines-per-block-ssn

?word1 - (word (page ?page) (rowNumber ?rowNumber1) (type ssn)

 This fired but ?word1 equals ?word2.
