FacetE

Abstract

Today's natural language processing and information retrieval systems heavily depend on word embedding techniques to represent text values. However, given a specific task deciding for a word embedding dataset is not trivial. Current word embedding evaluation methods mostly provide only a one-dimensional quality measure, which does not express how knowledge from different domains is represented in the word embedding models. To overcome this limitation, we provide a new evaluation data set called FacetE derived from 125M Web tables, enabling domain-sensitive evaluation. We show that FacetE can effectively be used to evaluate word embedding models. The evaluation of common general-purpose word embedding models suggests that there is currently no best word embedding for every domain.
