A Sliding-Window Drop-in Replacement for the HMM Part-of-Speech Tagger in Apertium

Summary

Although the title shows that it's a sliding-window drop-in replacement for the HMM tagger, actually we did three things further:

1) Besides the SW tagger, we also implemented the Light Sliding-Window (LSW) tagger, and successfully incorporated rules into the LSW tagger.

2) Instead of replacing the original HMM, we implemented the LSW tagger as an extension, so that the functionalities of the original HMM are fully kept.

3) We wrote a paper about the implementation of the SW and LSW tagger, and conducted a series of experiments.
