摘要:

我们引入了一种新的潜在向量空间模型,该模型可以联合学习单词、电子商务产品以及两者之间的映射的潜在表示,而无需显式注释。该模型的强大之处在于它能够直接建模产品和特定单词之间的区别关系。我们将我们的方法与现有的潜在向量空间模型(LSI,LDA和word2vec)进行比较,并将其作为学习排序设置中的一个功能进行评估。我们的潜在向量空间模型在学习更好的产品表示时实现了增强的性能。此外,从词到产品的映射和词的表示直接受益于在参数估计期间从产品表示传播回来的误差。我们对模型的性能进行了深入分析,并分析了学习表示的结构。

英文摘要:

We introduce a novel latent vector space model that jointly learns the latent representations of words, e-commerce products and a mapping between the two without the need for explicit annotations. The power of the model lies in its ability to directly model the discriminative relation between products and a particular word. We compare our method to existing latent vector space models (LSI, LDA and word2vec) and evaluate it as a feature in a learning to rank setting. Our latent vector space model achieves its enhanced performance as it learns better product representations. Furthermore, the mapping from words to products and the representations of words benefit directly from the errors propagated back from the product representations during parameter estimation. We provide an in-depth analysis of the performance of our model and analyze the structure of the learned representations.
