: A pushdown system is a graph G(P) of configurations of a pushdown automaton P. The model checking problem for a logic L is: given a pushdown automaton P and a formula L decide ...
This work is motivated by the necessity to automate the discovery of structure in vast and evergrowing collection of relational data commonly represented as graphs, for example ge...
A transitive orientation of an undirected graph is an assignment of directions to its edges so that these directed edges represent a transitive relation between the vertices of th...
Named Graphs is a simple, compatible extension to the RDF syntax that enables statements to be made about RDF graphs. This approach is in contrast to earlier attempts such as RDF r...
We generalize Holland's Schema Theorem to the setting that genes are arranged, not necessarily in a linear sequence, but as the nodes in a connected graph. We have experiment...
