Pitfall of Google tri-grams word similarity measure

This paper describes and examines google trigram word similarity based on google n-gram dataset. google tri-grams measure (gtm) is an unsupervised similarity measurement technique. the paper investigates gtm’s word similarity measure which is the state-of-the art of the measure and we eventually reveal its pitfall. we test the word similarity with mc-30 word pair dataset and compare the result against the other word similarity measures. after evaluation,gtm word similarity measures is found significantly fall behind other word similarity measure. the pitfall of gtm word similarity is detailed and proved with evidences.
