Is singular value decomposition useful for word similarity extraction?

This study compares simple hash-based methods for computing distributional similarity with the complex singular value decomposition approach. It comes to the conclusion that the simpler methods produce both better quality and can be computed at a fraction of the time required for SVD. (2011)

Knowledge-free Verb Detection through Tag Sequence Alignment.

This work presents an algorithm that is able to detect verbs relying on completely unsupervised language processing methods. Being able to recognize action clues in textual resources enables our applications to apply methods for deeper language understanding (such as relation extraction) in a completely unsupervised manner.

Towards Well-grounded Phrase-level Polarity Analysis.

Our approach to sentiment analysis shows that polarity of phrases can be composed out of the word’s polarity. Our polarity model is language-indepedent and thus, can be easily adapted to new languages / domains.
