Abstract

Recently a number of unsupervised approaches

have been proposed for learning vectors that capture

the relationship between two words. Inspired

by word embedding models, these approaches rely

on co-occurrence statistics that are obtained from

sentences in which the two target words appear.

However, the number of such sentences is often

quite small, and most of the words that occur in

them are not relevant for characterizing the considered

relationship. As a result, standard cooccurrence

statistics typically lead to noisy relation

vectors. To address this issue, we propose

a latent variable model that aims to explicitly determine

what words from the given sentences best

characterize the relationship between the two target

words. Relation vectors then correspond to the

parameters of a simple unigram language model

which is estimated from these words.
