摘要:

词义具有不同的方面,而现有的词表示将这些方面“压缩”到单个向量中,并且需要进一步分析以恢复不同维度的信息。受量子概率的启发,我们将单词表示为密度矩阵,它本质上能够表示混合状态。实验表明,密度矩阵表示可以有效地捕捉不同方面的单词的含义,同时保持与向量表示相当的可靠性。此外,我们提出了一种新的方法,结合相干求和和非相干求和的矢量和密度矩阵的计算。在词汇类比任务上取得了持续的提高。

英文摘要:

Word meaning has different aspects, while the existing word representation "compresses" these aspects into a single vector, and it needs further analysis to recover the information in different dimensions. Inspired by quantum probability, we represent words as density matrices, which are inherently capable of representing mixed states. The experiment shows that the density matrix representation can effectively capture different aspects of word meaning while maintaining comparable reliability with the vector representation. Furthermore, we propose a novel method to combine the coherent summation and incoherent summation in the computation of both vectors and density matrices. It achieves consistent improvement on word analogy task.
