We give a new proof showing that it is not possible to define in monadic second-order logic (MSO) a choice function on the infinite binary tree. This result was first obtained by G...
Previous work reports about SXSI, a fast XPath engine which executes tree automata over compressed XML indexes. Here, reasons are investigated why SXSI is so fast. It is shown tha...
We define a new model of automata for the description of bidirectional parsing strategies for tree adjoining grammars and a tabulation mechanism that allow them to be executed in ...
