VecShare: A Framework for Sharing Word Representation Vectors

This work presents a framework, called VecShare, that makes it easy to share and retrieve word embeddings on the Web, and performs an experimental evaluation of VecShare’s similarity strategies, and shows that they are effective at efficiently retrieving embeddeddings that boost accuracy in a document classification task.

Abstract

Many Natural Language Processing (NLP) models rely on distributed vector representations of words. Because the process of training word vectors can require large amounts of data and computation, NLP researchers and practitioners often utilize pre-trained embeddings downloaded from the Web. However, finding the best embeddings for a given task is difficult, and can be computationally prohibitive. We present a framework, called VecShare, that makes it easy to share and retrieve word embeddings on the Web. The framework leverages a public data-sharing infrastructure to host embedding sets, and provides automated mechanisms for retrieving the embeddings most similar to a given corpus. We perform an experimental evaluation of VecShare’s similarity strategies, and show that they are effective at efficiently retrieving embeddings that boost accuracy in a document classification task. Finally, we provide an open-source Python library for using the VecShare framework.
