Induction of Finite-State Covering Grammars for Text Normalization (joint work with Kyle Gorman)

In the first talk I argued for the use of covering grammars to guide the decoding in RNN text normalization, to help the system avoid "silly errors". This talk presents a deeper dive on our work on inducing such covering grammars from data. I start with presenting our work on inducing grammars for number names (123 verbalized as one hundred (and) twenty three). This work draws inspiration from the (small) linguistics literature on number names, and our method allows one to train finite-state transducers with small amounts of data ( a few hundred examples). I will compare the performance with that of an RNN trained on orders of magnitude more data. I will then report on our ongoing work on inducing grammars for a wider range of text normalization problems.
