俄语文学语篇中词频的变化

Variation of word frequencies in Russian literary texts

Vladislav Kargin

摘要:

本文研究俄语文学语篇中词频的变化。我们的研究结果表明,根据指数$0.62,$的幂律,一个词在文本中的频率的标准差取决于它的平均频率,这表明较罕见的词具有相对较大程度的频率波动性(即,“突发性”)。几个潜在因素模型已估计调查的词频分布的结构。一个词的频率波动依赖于它的平均频率可以解释为潜在因素分布的不对称性。

英文摘要:

We study the variation of word frequencies in Russian literary texts. Our findings indicate that the standard deviation of a word's frequency across texts depends on its average frequency according to a power law with exponent $0.62,$ showing that the rarer words have a relatively larger degree of frequency volatility (i.e., "burstiness"). Several latent factors models have been estimated to investigate the structure of the word frequency distribution. The dependence of a word's frequency volatility on its average frequency can be explained by the asymmetry in the distribution of latent factors.
