... a re-casting of the conventional LTAG parser in terms of such au- tomata 2. For this automaton-based parser, the grammar structures are not trees, but automata corresponding to tree traversals ... merging all the final states into one. The parser maintains a dynamic record of which trees are valid for states (in particular fi- nal states) in the parse table. This means...
