The Fuzzy Description Logic ALCFH with Hedge Algebras as Concept Modifiers

  title={The Fuzzy Description Logic ALCFH with Hedge Algebras as Concept Modifiers},
  author={Steffen H{\"o}lldobler and Hans-Peter St{\"o}rr and Dinh Khang Tran},
In this paper we present the fuzzy description logic ALCFH introduced, where primitive concepts are modified by means of hedges taken from hedge algebras. ALCFH is strictly more expressive than FuzzyALC defined in [11]. We show that given a linearly ordered set of hedges primitive concepts can be modified to any desired degree by prefixing them with appropriate chains of hedges. Furthermore, we define a decision procedure for the unsatisfiability problem in ALCFH , and discuss knowledge base… CONTINUE READING
