TAILIEUCHUNG - Báo cáo khoa học: "Improved Lexical Alignment by Combining Multiple Reified Alignments"

We describe a word alignment platform which ensures text pre-processing (tokenization, POS-tagging, lemmatization, chunking, sentence alignment) as required by an accurate word alignment. The platform combines two different methods, producing distinct alignments. The basic word aligners are described in some details and are individually evaluated. The union of the individual alignments is subject to a filtering postprocessing phase. Two different filtering methods are also presented. The evaluation shows that the combined word alignment contains less errors than the best individual aligner. . | Improved Lexical Alignment by Combining Multiple Reified Alignments Dan Tufi Institute for Artificial Intelligence 13 13 Septembrie 050711 Bucharest 5 Romania tufis@ Radu Ion Institute for Artificial Intelligence 13 13 Septembrie 050711 Bucharest 5 Romania radu@ Alexandru Ceau u Institute for Artificial Intelligence 13 13 Septembrie 050711 Bucharest 5 Romania alceausu@ Dan ặteíănescu Institute for Artificial Intelligence 13 13 Septembrie 050711 Bucharest 5 Romania danstef@ Abstract We describe a word alignment platform which ensures text pre-processing to-kenization POS-tagging lemmatization chunking sentence alignment as required by an accurate word alignment.

Dieterich 1998 discusses conditions under which different decisions in his case classifications may be combined for obtaining a better result. Essentially a successful automatic combination method would require comparable performance for the decision makers and additionally that they should not make similar errors. This idea has been exploited by various NLP researchers in language modelling statistical POS tagging parsing etc. We developed two quite different word aligners driven by two distinct objectives the first one was motivated by a project aiming at the development of an interlingually aligned set of wordnets while the other one was developed within an SMT ongoing project. The first one was used for validating against a .
