RDRPOSTagger
RDRPOSTagger is a robust and easy-to-use toolkit for POS and morphological tagging. It employs an error-driven approach to automatically construct tagging rules in the form of a binary tree.
-
RDRPOSTagger obtains very fast tagging speed and achieves a competitive accuracy in comparison to the state-of-the-art results. See experimental results including performance speed and tagging accuracy for 13 languages in our AI Communications article.
-
RDRPOSTagger now supports pre-trained UPOS, XPOS and morphological tagging models for about 80 languages. See folder
Modelsfor more details.
The general architecture and experimental results of RDRPOSTagger can be found in our following papers:
