ontology is a requirement engineering product and the key to knowledge discovery. it includes the terminology to describe a set of facts, assumptions, and relations with which the detailed meanings of vocabularies among communities can be determined. this is a qualitative content analysis research. this study has made use of ontology for the first time to discover the knowledge of vaccine in ir...

Road recognition from video sequences has been solved robustly only for small, often simplified subsets of possible road configurations. This contribution argues for a massive augmentation of the amount of prior knowledge to enable the development of more generally applicable estimators. Description Logic is introduced as an expressive knowledge representation formalism for scene understanding....

A graph is edge-distance-regular when it is distance-regular around each of its edges and it has the same intersection numbers for any edge taken as a root. In this paper we give some (combinatorial and algebraic) proofs of the fact that every edge-distance-regular graph Γ is distance-regular and homogeneous. More precisely, Γ is edge-distance-regular if and only if it is bipartite distance-reg...

The fundamental construct of numerical algebraic geometry is the representation of an irreducible algebraic set, A, by a witness set, which consists of a polynomial system, F , for which A is an irreducible component of V(F ), a generic linear space L of complementary dimension to A, and a numerical approximation to the set of witness points, L ∩A. Given F , methods exist for computing a numeri...
