Subsumption Propagation between Remote Ontologies in Distributed Description Logic
Distributed Description Logics (DDL) is a KR formalism that enables reasoning with multiple ontologies interconnected by directional semantic mapping. Subsumption propagation in DD...

Mapping gene expression quantitative trait loci by singular value decomposition and independent component analysis
Background: The combination of gene expression profiling with linkage analysis has become a powerful paradigm for mapping gene expression quantitative trait loci (eQTL). To date, ...
