Center node: "a comparison of natural english and artificial esperanto languages a multifractal method based analysis"
  Abstract: from each other. We construct one dimensional time series like signals using either word lengths or word frequencies. We use the multifractal ideas for sorting out correlations in the writings. In order to check the robustness of the methods we also write (!) (consider? ) the corresponding shued texts. We compare characteristic functions and e.g. observe marked dierences in the (far from parabolic) f( ) curves, dierences which we attribute to Tsallis non extensive statistical features in the frequency time series and length time series. The esperanto text has more extreme vallues. A very rough approximation consists in modeling the texts as a random Cantor set if resulting from a binomial cascade of long and short words (or words and blanks). This leads to parameters characterizing the text style, and most likely in ne the author writings. PACS numbers:
