There is an increasing interest in the NLP community in developing tools for annotating historical data; for example; to facilitate research in the field of corpus linguistics. In this work; we experiment with several PoS taggers using a sub-corpus of the Icelandic Saga Corpus. This is carried out in three main steps. First; we evaluate taggers; which were trained on Modern Icelandic; when tagging Old Icelandic. Second; we semi-automatically correct errors in the training corpus using a bootstrapping method. Finally; we evaluate the taggers on the corrected training corpus. The best performing single tagger is Stagger; a tagger based on the averaged perceptron algorithm; obtaining an accuracy of 91.76%. By combining the output of three taggers; using a simple voting scheme; the accuracy increases to 92.32%.
