<p>You might want to try <a href="http://rdrpostagger.sourceforge.net/" rel="nofollow">RDRPOSTagger</a>: a robust, easy-to-use and language-independent toolkit for POS and morphological tagging.</p>

<p>(Programming language: Python &amp; Java)</p>

<p>RDRPOSTagger obtains fast performance in both learning and tagging process. In addition, RDRPOSTagger achieves a very competitive accuracy in comparison to the state-of-the-art results. See experimental results including performance speed and tagging accuracy in <a href="http://arxiv.org/abs/1412.4021" rel="nofollow">this paper</a>.</p>

<p>RDRPOSTagger now supports pre-trained POS and morphological tagging models for 13 languages, including Thai and Vietnamese.</p>
Korean, Thai and Indonesian POS tagger
<p>Can someone recommend an open source POS tagger for Korean, Indonesian, Thai and Vietnamese?</p>

<p>That I can use to tag the corpus data that I currently have. (e.g. <a href="http://nlp.stanford.edu/software/index.shtml" rel="noreferrer">the stanford-postagger</a>)</p>

<p>If you are a dev and care to share and let me test out the POS tagger, I don't mind either.</p>

<p>With some modifications of the output, I've POS tagged the Vietnamese data with <a href="http://sourceforge.net/projects/jvntextpro/" rel="noreferrer">jvntextpro</a></p>

<p>But I'd still like more input on Korean, Indonesian and Thai POS tagging.</p>
