基于语义词嵌入的文本分割

Text Segmentation based on Semantic Word Embeddings

Cornell University(康奈尔大学)

Alexander A Alemi, Paul Ginsparg

摘要:

我们探讨了语义词嵌入在文本分割算法中的应用,包括C99分割算法和受分布式词向量表示启发的新算法。通过开发一个通用的框架来讨论一类分割目标,我们研究了贪婪与精确优化方法的有效性,并提出了一种新的迭代细化技术,以提高贪婪策略的性能。我们使用已知的指标将我们的结果与已知的基准进行比较。我们展示了未经训练的方法与我们的内容向量分割(CVS)在Choi测试集上的最新性能。最后,我们将分割过程应用于由从arXiv.org数据库中的学术文章中提取的文本组成的野外数据集。

英文摘要:

We explore the use of semantic word embeddings in text segmentation algorithms, including the C99 segmentation algorithm and new algorithms inspired by the distributed word vector representation. By developing a general framework for discussing a class of segmentation objectives, we study the effectiveness of greedy versus exact optimization approaches and suggest a new iterative refinement technique for improving the performance of greedy strategies. We compare our results to known benchmarks, using known metrics. We demonstrate state-of-the-art performance for an untrained method with our Content Vector Segmentation (CVS) on the Choi test set. Finally, we apply the segmentation procedure to an in-the-wild dataset consisting of text extracted from scholarly articles in the arXiv.org database.
