Let's explore this:
(and
(between 10 5 11)
(between 10 4 11)
(between 10 6 11)
(between 10 7 11))
Using the KI translator this becomes:
AND
10 is between 5
10 is between 11
10 is between 4
10 is between 11
10 is between 6
10 is between 11
10 is between 7
10 is between 11. (05)
What semantics does the between predicate have? (06)
How about the quaternary predicate, isBetweenOnPath?
Can you express the following with triples: (07)
(and
(isBetweenOnPath WashingtonDC Maryland Virginia I95)
(not (isBetweenOnPath WashingtonDC Maryland Virginia I495))) (08)
