Inducing Lexico-Structural Transfer Rules from Parsed Bi-texts

摘要

This paper describes a novel approach to inducing lexico-structural transfer rules from parsed bi-texts using syntactic pattern matching statistical co-occurrence and error-driven filtering the present initial evaluation results and discuss future directions. This paper describes a novel approach to inducing transfer rules from syntactic parses of bi-texts and available bilingual dictionaries. The approach consists of inducing transfer rules using the four major steps described in more detail below: (1) aligning the nodes of the parses: (2) generating candidate rules from these alignments: (3) ordering candidate rules by co-occurrence: and (4) applying error-driven filtering to select the final set of rules. Our approach is based on lexico- structural transfer (Nasr et. al. 1997) and extends recent work reported in (Han et al. 2000) about Korean to English transfer in particular. Whereas Han et al. focus on high quality domain-specific translation using handcrafted transfer rules in this work we instead focus on automating the acquisition of such rules.
