Hebrew has a wide coverage lexicon / morphological-analyzer (henceforth, KC Analyzer) available 2 , but its tagset is different than the one used by the Hebrew Treebank.
unlike the oracle segmentation case, here the semisupervised lexical probabilities (LexProbs) have a major effect on the parser performance (∼ 69 to ∼ 73.5 F-score), an overall improvement of ∼ 6.6 F-points over the Baseline, which is the previous state-of-the art for this joint task.
