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. -W On 23 August 2011 06:17, Cathy & Bob Crothers <crothers4...@comcast.net>wrote: > I would like find ?word1 and ?word2 such that the absolute value of > ?rowNumber1 minus?rowNumber2 is the minimum number and ?word1 is not equal > to ?word2**** > > ** ** > > 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) > (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**** > > ) **** > > ** ** > > This rule never fired.**** > > ** ** > > ** ** > > ** ** > > I tried **** > > (defrule find-lines-per-block-ssn**** > > ?word1 <- (word (page ?page) (rowNumber ?rowNumber1) (type ssn) > (text ?text1) )**** > > ?word2 <- (word (page ?page) (rowNumber ?rowNumber2) (type ssn) > (text ?text2) )**** > > (not **** > > (word (page ?page) (rowNumber ?rowNumberVar&:(< (abs (- > ?rowNumberVar ?rowNumber1) ) (abs (- ?rowNumber2 ?rowNumber1) ) ) ) )**** > > )**** > > =>**** > > ; do someting**** > > ) **** > > ** ** > > This fired but ?word1 equals ?word2.**** > > ** ** > > Thanks**** > > ** ** > > Bob**** > > ** ** > > ** ** >
