Bootstrapping Techniques for Polysynthetic Morphological Analysis
Figure 4: Error analysis of lane2019’s FST model of Kunwinjku verbs shows 5 classes of error and the percent of the total error attributed to each class.
['Error Class', '% of Error']
The FST relies on a lexicon to provide analyses for inflected forms, and when it comes across OOV morphs, or verb stems modified by processes like reduplication, it fails to return an analysis. We sort the coverage issues into classes, and remark that the largest source of error comes from reduplication, followed by variation in tense/aspect/mood (TAM) inflection We address each of these problems in the following sections.
