This work presents a new algorithm to detect RDF graph isomorphism. Furthermore, we show that isomorphic RDF graphs issue can be solved in an efficient manner using graphs information. Algorithm efficiency resides in the detection of RDF subgraphs isomorphism. The theoretical complexity of algorithm is O(nlogn+eG), where n is the number of vertices and eG is the cost to check all edges. The proposed...
Nowadays there are several data mining algorithms applied to the resolution of many different problems, such as the classification of patterns. However, when these algorithms are used separately to classify they usually present an inferior performance compared to the performance obtained by combined models. The bagging and boosting techniques combine models of the same kind in a competitive form,...
The aliphatic hydrocarbon composition (acyclic isoprenoids, hopanoids and steroids) of oils from the most productive fields in the southern geological Province of Cuba have been studied. This province is defined by its position with respect to the Cretaceous overthrust belt generated during the formation of oceanic crust along the axis of the proto-Caribbean Basin. The relative abundances of 18α(H)-22,29,30-trisnorneohopane,...
