A Feature-Rich Vietnamese Named-Entity Recognition Model
Table 5: Proposed NER systems without chunking tag-based features. We compare default PoS with PoS generated by other tools.
['[BOLD] Setting', '[BOLD] Precision', '[BOLD] Recall', '[ITALIC] F1']
In the next experiment, we remove chunk features in the model, and compare the accuracy of the model when we use PoS tags generated by different tools. However incorporating PoS tags generated by other PoS tagging tools did not help to improve against the model without PoS and chunking tags.
