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 simulation of these nondeterministic automata in polynomial time, independent of the parsing strategy. The proposed application of this work is the design of efficient parsing algorithms for tree-adjoining grammars and related formalisms.}, ANNOTE = {COLIURL : Pardo:2000:TAT.pdf Pardo:2000:TAT.ps} } @Article{Bertsch_Nederhof:1999, AUTHOR = {Bertsch, Eberhard and Nederhof, Mark-Jan}, TITLE = {On Failure of the Pruning Technique in Error Repair in Shift-Reduce Parsers}, YEAR = {1999}, JOURNAL = {ACM Transactions on Programming Languages and Systems (TOPLAS)}, VOLUME = {21}, NUMBER = {1}, PAGES = {1-10}, URL = {http://www.dfki.de/dfkibib/publications/docs/nederhof99d.ps.gz}, ABSTRACT = {A previous article presented a technique to compute the least-cost error repair by incrementally generating congurations that result from inserting and deleting tokens in a syntactically incorrect input.
