Bidirectional Automata for Tree Adjoining Grammars
نویسندگان
چکیده
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 polynomial time. This new model of automata provides a modular way of describing bidirectional parsing strategies for TAG, separating the description of a strategy from its execution.

Tabulation of Automata for Tree-Adjoining Languages
We propose a modular design of tabular parsing algorithms for treeadjoining languages. The modularity is made possible by a separation of the parsing strategy from the mechanism of tabulation. The parsing strategy is expressed in terms of the construction of a nondeterministic automaton from a grammar; three distinct types of automaton will be discussed. The mechanism of tabulation leads to the...
متن کاملTree-adjoining grammars and lexicalized grammars
In this paper, we will describe a tree generating system called tree-adjoining grammar(TAG)and state some of the recent results about TAGs. The work on TAGS is motivated by linguistic considerations. However, a number of formal results have been established for TAGs, which we believe, would be of interest to researchers in tree grammars and tree automata. After giving a short introduction to TA...
متن کاملBidirectional parsing of TAG without heads
We present a bottom-up bidirectional parser for Tree Adjoining Grammars that is an extension of the parser defined by De Vreught and Honig for Context Free Grammars. Although this parser does not improve the complexity of the parsers defined in the literature, it presents several characteristics that can be of interest for practical parsing of natural languages.
متن کاملPractical aspects in compiling tabular TAG parsers
This paper describes the extension of the system DyALog to compile tabular parsers from Feature Tree Adjoining Grammars. The compilation process uses intermediary 2-stack automata to encode various parsing strategies and a dynamic programming interpretation to break automata derivations into tabulable fragments.
