A survey of effective characterizations of tree logics. If L is a logic, then an effective characterization for L is an algorithm, which inputs a tree automaton and replies if the...
The IPSI XQuery Demonstrator (IPSI-XQ) implements the XQuery surface syntax, its mapping to the XQuery Core Language, and the static and dynamic semantics of XQuery Core "by t...
Timed automata has been used as a powerful formalism for specifying, designing, and analyzing real time systems. We consider the generalization of timed automata to Pushdown Timed ...
In this paper we present an approach that combines multimedia reasoning and natural language processing for the semantic integration of automatic and manual image annotations base...
