摘要:

近年来,拓扑数据分析已被广泛用于处理高维噪声数据的问题。然而文本表示往往是高维和噪声的,拓扑数据分析在自然语言处理中的应用还很少。在本文中,我们介绍了一种新的算法来提取拓扑特征的词嵌入表示的文本,可用于文本分类。拓扑数据分析以词嵌入为研究对象,可以解释嵌入的高维空间,发现不同嵌入维数之间的关系。我们将使用持久同源性,拓扑数据分析中最常用的工具,用于我们的实验。检查我们的拓扑算法长文本文档,我们将显示我们定义的拓扑功能可能优于传统的文本挖掘功能。

英文摘要:

In recent years, topological data analysis has been utilized for a wide range of problems to deal with high dimensional noisy data. While text representations are often high dimensional and noisy, there are only a few work on the application of topological data analysis in natural language processing. In this paper, we introduce a novel algorithm to extract topological features from word embedding representation of text that can be used for text classification. Working on word embeddings, topological data analysis can interpret the embedding high-dimensional space and discover the relations among different embedding dimensions. We will use persistent homology, the most commonly tool from topological data analysis, for our experiment. Examining our topological algorithm on long textual documents, we will show our defined topological features may outperform conventional text mining features.
