Description Logics Why not First Order Logic (FOL)? FOL, which we explained previously, is a knowledge representation language which can be used to express a variety of ideas. Expressivity is a measure of the modelling power of a knowledge representation language. The expressivity of FOL is a double-edged sword. When trying to determine whether particular statements are true, more expressive knowledge representation languages require greater computational resources. FOL is undecidable, meaning that reasoning programs can't be written that are guaranteed to produce correct results without the possibility that they will never terminate (i....
