摘要:

在本文中,我们将文档修订检测问题建模为依赖于计算文档距离的最小成本分支问题。此外,我们提出了两个新的文档距离的措施,基于词向量的动态时间弯曲(wDTW)和基于词向量的树编辑距离(wTED)。我们的修订检测系统是为大规模语料库设计的,并在Apache Spark中实现。我们证明,我们的系统可以更精确地检测修订比国家的最先进的方法,利用维基百科的修订转储https://snap.stanford.edu/data/wiki-meta.html和模拟数据集。

英文摘要:

In this paper, we model the document revision detection problem as a minimum cost branching problem that relies on computing document distances. Furthermore, we propose two new document distance measures, word vector-based Dynamic Time Warping (wDTW) and word vector-based Tree Edit Distance (wTED). Our revision detection system is designed for a large scale corpus and implemented in Apache Spark. We demonstrate that our system can more precisely detect revisions than state-of-the-art methods by utilizing the Wikipedia revision dumps https://snap.stanford.edu/data/wiki-meta.html and simulated data sets.
