Similarity Based Estimation

We compare four similarity-based esti- mation methods against back-off and maximum-likelihood estimation meth- ods on a pseudo-word sense disam- biguation task in which we controlled for both unigram and bigram …...

This paper describes unsupervised learn- ing algorithm for disambiguating verbal word senses using term weight learning. In our method, collocations which char- acterise every sense are extracted using similarity-based estimation. …...
