Abstract
A method and system that uses a chunking technique to guide the parsing. A chunk is a portion of the input for which the system has determined that a sufficient number of syntax rules have been applied such that further application of syntax rules to that chunk is unlikely to produce a more accurate sub-parse for that chunk. When using the chunking technique, the system selects a syntax rule to apply to the current partial parse (sub-trees) of the input sentence. The selected syntax rule has a high probability relative to other syntax rules that can be applied to the one or more potential sub-trees of the input sentence. The system then applies the selected syntax rule to the potential sub-trees of the input sentence to form a new potential sub-trees of the input sentence. When the system determines that syntax rules with low probabilities have recently been applied, the system disables application of syntax rules to a portion of parse of the input sentence (i.e., a chunk) so that that syntax rules can be applied to the other portion of the input sentence.
