Improved Part-of-speech Tagging by Log-linear Models
|
Abstract:
This paper presented our latest approaches for improving English part-of-speech tagging with a large tagset by using a log-linear model.We found that integration of multiple probability models log-linearly led to significant im- provements on part-of-speech tagging.We compared our proposed approach with the two traditional approaches,hid- den markov model(HMM)and maximum entropy principle.The HMM approach was implemented by using a new smoothing method while for the maximum entropy approach,we integrated de...
