<div>Dear All</div>
<div> </div>
<div>Has anybody reviewed or assessed the rate of accuracy of POS-tagging (not error tagging) to learner corpora, or simply reported the use of POS-tagging in their learner corpora studies? Due to the unexpected non-native features of learner English, POS tagging systems designed for NSs will need some modification or adjustment when used on learner corpora. I wonder whether somebody has already worked out some better solutions than simply using POS tagging software for general purposes. I am aware that this thorny issue of learner corpora study was addressed somewhat before (for example, Granger in Granger 2002) and there were few studies based on POS tagging to learner corpora, but in this fast growing area there might be some progress which has already largely outdated the problem (POS-tagging to learner corpora) (fingers crossed).
