摘要:

我们估计了自然语言文本在字长表示中的$n$ -gram熵,发现这些熵对文本语言和体裁敏感。我们将这种敏感性归因于单个单词长度的概率分布的变化,并强调单词长度在5到10之间的概率的均匀性的关键作用。此外,与混洗数据的熵的比较揭示了估计的$n$ -gram熵的字长相关性的影响。

英文摘要:

We estimate the $n$-gram entropies of natural language texts in word-length representation and find that these are sensitive to text language and genre. We attribute this sensitivity to changes in the probability distribution of the lengths of single words and emphasize the crucial role of the uniformity of probabilities of having words with length between five and ten. Furthermore, comparison with the entropies of shuffled data reveals the impact of word length correlations on the estimated $n$-gram entropies.
