Abstract
We present KLcpos3, a language similar-ity measure based on Kullback-Leibler di-vergence of coarse part-of-speech tag tri-gram distributions in tagged corpora. It has been designed for multilingual delexi-calized parsing, both for source treebank selection in single-source parser trans-fer, and for source treebank weighting in multi-source transfer. In the selection task, KLcpos3 identifies the best source treebank in 8 out of 18 cases. In the weighting task, it brings +4.5% UAS absolute, compared to unweighted parse tree combination.
