Wedefine an algebra of ternary relations for cyclic ordering of 2Dorientations. Thealgebra (1) is a refinement of the CYCORDtheory; (2) contains 24 atomic relations, hence 224 gen...
AI planning techniques are beginning to find use in a number of practical planning domains. However, the backward-chaining and partial-order-planning control strategies traditiona...
We consider the problem of representing sets of 3D points in the context of 3D reconstruction from point matches. We present a new representation for sets of 3D points, which is g...
We characterise the set of subalgebras of Allen's algebra which have a tractable satisfiability problem, and in addition contain certain basic relations. The conclusion is th...
We propose an extension of the syntactic restriction for complex role inclusion axioms in the description logic SROIQ. Like the original restriction in SROIQ, our restrictions can ...
