... capture syntactization of the given t-node, with values such as n:subj – semantic noun (s.n.) in sub- ject position, n :for+ X – s.n. with preposition for, n:poss – possessive form of s.n., v:because+fin ... Therefore we suggest to use HMTM and tree-modified Viterbi algorithm for tasks interpretable as label- ing nodes of dependency trees. In par- ticular, we show that the transfer pha...
