Computational Representation Of Russian Aspectual Morphology With A Focus On Perfective Prefixation, Natalia Tyulina

Dissertations, Theses, and Capstone Projects

This work performs an empirical analysis of Russian aspectual morphology focusing on perfective derivation via prefixation. We present a number of computational experiments measuring productivity of morphological processes of prefixation that form perfective verbs from simple imperfective verbs. Several hypotheses related to the argument structure of perfective verbs vs. their prefixed derivatives are tested statistically. Furthermore, we investigate semantic relatedness by computing cosine similarities of unprefixed verbs vs. their prefixed versions. Finally, we analyze the correlation between productivity, frequency, argument structure and semantic similarity across both simple imperfective – prefixed perfective verb forms, and various perfectivizing verbal prefixes.
