Kurzfassung
We propose a novel method for reasoning in the description logic SHIQ. After a
satisfiability preserving transformation from SHIQ to the description logic
ALCIb, the obtained ALCIb Tbox T is converted into an ordered binary decision
diagram (OBDD) which represents a canonical model for T. This OBDD is turned
into a disjunctive datalog program that can be used for Abox reasoning. The
algorithm is worst-case optimal w.r.t. data complexity, and admits easy
extensions with DL-safe rules and ground conjunctive queries.
