摘要:

统计方法已广泛应用于许多实际的自然语言处理应用中。更具体地说,复杂网络的概念和方法,从动力系统理论已成功地应用于识别书面文本中的文体模式。尽管大量的研究致力于用物理模型来表示文本,但只有少数研究评估了来自文体波动分析的属性的相关性。由于波动代表了表征无数真实系统的关键因素,因此本研究通过复杂网络的拓扑分析和不确定性测量来分析文本中的文体波动特性。结果表明,不同的作者表现出不同的波动模式。特别是,它被发现,它是可能的,以确定作者的书籍使用特定的词汇的不确定性。总之,这里描述的结果表明,风格波动中发现的模式可以用来分析其他相关的复杂系统。此外,与文本风格波动相关的新模式的发现表明,这些模式可能有助于改善许多基于风格的自然语言处理任务的技术水平。

英文摘要:

Statistical methods have been widely employed in many practical natural language processing applications. More specifically, complex networks concepts and methods from dynamical systems theory have been successfully applied to recognize stylistic patterns in written texts. Despite the large amount of studies devoted to represent texts with physical models, only a few studies have assessed the relevance of attributes derived from the analysis of stylistic fluctuations. Because fluctuations represent a pivotal factor for characterizing a myriad of real systems, this study focused on the analysis of the properties of stylistic fluctuations in texts via topological analysis of complex networks and intermittency measurements. The results showed that different authors display distinct fluctuation patterns. In particular, it was found that it is possible to identify the authorship of books using the intermittency of specific words. Taken together, the results described here suggest that the patterns found in stylistic fluctuations could be used to analyze other related complex systems. Furthermore, the discovery of novel patterns related to textual stylistic fluctuations indicates that these patterns could be useful to improve the state of the art of many stylistic-based natural language processing tasks.
