Compressing Word Embeddings Using Syllables
share
This work examines the possibility of using syllable embeddings, instead of the often used n-gram embeddings, as subword embeddings. We investigate this for two languages: English and Dutch. To this end, we also translated two standard English word embedding evaluation datasets, WordSim353 and SemEval-2017, to Dutch. Furthermore, we provide the research community with data sets of syllabic decompositions for both languages. We compare our approach to full word and n-gram embeddings. Compared to full word embeddings, we obtain English models that are 20 to 30 times smaller while retaining 80 70 used, our models can be trained in a matter of minutes, as opposed to hours for the n-gram approach. We identify a path toward upgrading performance in future work. All code is made publicly available, as well as our collected English and Dutch syllabic decompositions and Dutch evaluation set translations.
