Old Swedish Part-of-Speech Tagging between Variation and External Knowledge
Yvonne Adesam, Gerlof Bouma · 2016
We present results on part-of-speech and morphological tagging for Old Swedish (1225–1526). In a set of experiments we look at the difference between withincorpus and across-corpus accuracy, and explore ways of mitigating the effects of variation and data sparseness by adding different types of dictionary information. Combining several methods, together with a simple approach to handle spelling variation, we achieve a major boost in tagger performance on a modest test collection.
