动态语义空间中的无监督词义消歧

Unsupervised word sense disambiguation in dynamic semantic spaces

摘要:

本文主要研究在新词语和新义频繁出现的动态语义空间中快速自动地区分词义的能力。这些空间是从不断发展的数据集(如维基百科、专利授权和申请的存储库或用于技术辅助审查和电子发现的大量法律文件集)“动态”构建的。这种直接性排除了监督以及先验训练集的使用。我们表明,一个术语的各种意义,可以自动明显与一个简单的聚类算法,每个意义是一个向量的语义空间。虽然我们在这里只考虑通过使用随机向量构建的语义空间,但该算法应该适用于任何类型的嵌入,前提是可以计算术语之间有意义的相似性,并且至少满足两个基本条件,即含义接近的术语具有高相似性,含义不相关的术语具有接近零的相似性。

英文摘要:

In this paper, we are mainly concerned with the ability to quickly and automatically distinguish word senses in dynamic semantic spaces in which new terms and new senses appear frequently. Such spaces are built '"on the fly" from constantly evolving data sets such as Wikipedia, repositories of patent grants and applications, or large sets of legal documents for Technology Assisted Review and e-discovery. This immediacy rules out supervision as well as the use of a priori training sets. We show that the various senses of a term can be automatically made apparent with a simple clustering algorithm, each sense being a vector in the semantic space. While we only consider here semantic spaces built by using random vectors, this algorithm should work with any kind of embedding, provided meaningful similarities between terms can be computed and do fulfill at least the two basic conditions that terms which close meanings have high similarities and terms with unrelated meanings have near-zero similarities.
