Description:		COWAL is a wrapper of two stand-alone word aligners [[http://www.clarin.eu/tools/yawa-yet-another-word-aligner|YAWA]] and [[http://www.clarin.eu/tools/meba-word-aligner|MEBA]]. COWAL merges the alignments produced by each stand-alone aligner and then uses a trained SVM classifier to prune the unlikely alignment links. The classifier is based on the [[http://www.csie.ntu.edu.tw/~cjlin/papers/quadworkset.pdf|LIBSVM kit]], used with the default parameters (C-SVC classification and radial basis kernel function). The classifier was trained with positive and negative hand-validated examples of word alignment links. With the current F-measure of 83.98%, COWAL won the first place in the lexical alignment competition held with the occasion of the 43rd Annual Meeting of the Association for Computational Linguistics (ACL’05) workshop on “Building and Using Parallel Texts: Data Driven Machine Translation and Beyond”, Ann Arbor, USA.
