Long-range correlations in Korean literary corpora

Abstract

Recently, Montemurro et al. showed that there would be a long-range correlation in Shakespeare’s 36 plays written in English. However it is not clear that similar result can be found in other language which has very different grammar structure from English. So we examine whether there exists a long-range correlation in Shakespeare’s plays translated into Korean which would have very different syntactic rules from English. Additionally, we perform the same experiment for 12 novels written by four Korean popular writers in order to see the difference due to the styles of the writers. As a result, we find Hurst’s exponents of 0.632 ± 0.03 in Shakespeare’s plays translated in Korean. Also we find the similar values of Hurst’s exponent even to the novels of the Korean popular writers. It implies that regardless of languages, there exists a long-range correlation in literary corpora.
