Sentence: Tom is not Paul's daughter or Tom is tall.
Here the interpretation in predicate logic notation:
[[¬daughter-of-someone (Tom,Paul) v tall(Tom)]] = true
because [[¬daughter-of-someone (Tom,Paul)]]= true
- because I(Tom)= <Tom>, I(Paul)= <Paul> and <Tom,Paul> is NOT in the set of I(daughter-of-someone)
- because I(Tom)= <Tom>, I(Paul)= <Paul> and <Tom,Paul> is NOT in the set of I(daughter-of-someone)
and [[tall(Tom)]] = false
- because I(Tom)= <Tom> and <Tom> is NOT an element of I(tall).
- because I(Tom)= <Tom> and <Tom> is NOT an element of I(tall).
Disjunction (v): At least one of the atomic formulae has to be true in order for the complex formula to be true.
