Experiments in Base-NP Chunking and Its Role in Dependency Parsing for Thai

This paper studies the role of base-NP information in dependency parsing for Thai. The baseline performance reveals that the base-NP chunking task for Thai is much more difficult than those of some languages (like English). The results show that the parsing performance can be improved (from 60.30% to 63.74%) with the use of base-NP chunk information, although the best chunker is still far from perfect (F=1 = 83.06%).
