A computational model of human parsing

  • Steven P. Abney


This report describeslicensing-structure parsing (LS-parsing), a computational model of human parsing. LS-parsing corresponds to human parsing at three points: (1) the order in which the LS parser builds nodes is psychologically more accurate than the orders in which either LL or LR parsers build nodes, (2) the LS parser's preferences in resolving local ambiguities are preferable to Frazier's strategies on both empirical and theoretical grounds, and (3) the backtracking strategies the parser uses when it has made an error at an earlier choice point model the distinction betweenweak andstrong garden paths-strong garden paths being irrecoverable, weak garden paths causing psychological difficulty, but not preventing recovery of the correct structure.
