Subject: Re: [Humanist] 33.272: randomising: examples Dear Willard, Geoffrey's mention of word clouds leads me to add some additional thoughts on randomization. First, I think the randomization Geoffrey mentions may be a bug rather than a feature of word clouds. The fact that words with the same frequency can occur with different orientations and different colors means that it is unlikely that anyone looking at a word cloud can tell which words occur at the same frequency. In word clouds, beauty (which has its value) has been prioritized over interpretability. A very early use of randomization can be found in the great progenitor, John F. Burrows's, "Not Unless You Ask Nicely: The Interpretative Nexus Between Analysis and Information," Literary and Linguistic Computing, Vol. 7, No. 2,1992, where he uses random selection of sections of texts to equalize the influence of authors. Stylo/R implements randomization in many places, for example in Rolling Classification. See Eder, M., Rybicki, J. and Kestemont, M. (2016). Stylometry with R: a package for computational text analysis. "R Journal", 8(1): 107-121. Finally, one of the most common uses of randomization these days is in topic modeling. Mallet uses a random seed in text sampling, which results in the variability in topic models that often disconderts new users of Mallet. My experience is that running Mallet twice without setting a random seed results in two models in which it is normal for the average match between the most similar topics in the two models to be 30% or less. That is, on average, less than 30% of the words in each pair of most similar topics in the two models are the same, on average. (A relatively crude comparison function is implemented in my Prepare and Visualize Mallet Topics spreadsheet, available at https://wp.nyu.edu/exceltextanalysis/.) Best, David -- David L.
