Joint POS Tagging and Dependency Parsing with Transition-based Neural Networks
Table 5: Interaction between POS tagging and dependency parsing. “tag → parse” denotes that parsing leverages lexical information and “tag ← parse” denotes that tagging exploits syntactic information. The interactions can be disabled as shown in Eq. (10)-(12). The tagging and parsing results are evaluated on the Chinese Penn Treebank development set.
['Interaction tag → parse', 'Interaction tag ← parse', 'POS', 'UAS', 'LAS']
We observe that disabling the interactions between tagging and parsing significantly deteriorates both tagging and parsing quality.
