Parsing Natural Language Sentences by Semi-supervised Methods
Table 2: Prague versus full Stanford annotation style, UAS averaged over 30 target languages. The Lexicalized and Delexicalized parser is monolingual; the Transfer parser is a combination of 29 parsers trained on source treebanks, and then applied to the remaining target language. Also lists UAS measured only on non-punctuation nodes.
['Setup', 'Lex', 'Delex', 'Transfer']
As a preliminary experiment, we compared the Prague version with its fully stanfordized version. It can be seen that the Stanford version performs much worse than the Prague one – its results are lower by around 5% UAS absolute.
