<h1>Misspelling Rates in Amazon Reviews Are Predictable via a Neural Network Based Just on Basic Astronomy of the Day</h1> <p>by Renay Oshop <a href="http://AyurAstro.com" rel="nofollow">AyurAstro.com</a> Twitter:<a href="https://twitter.com/AyurAstro" rel="nofollow">@AyurAstro</a></p> <p>A version of this write-up was accepted for publication by <em>National Council for Geocosmic Research</em> <a href="https://geocosmic.org/" rel="nofollow">https://geocosmic.org/</a>. I am grateful.</p> <p>The original data from <em>Amazon</em> is 17.6 GB, too big to upload to OSF. However, it can be downloaded here: <a href="https://www.dropbox.com/s/11mjgy84ms9ldsq/aggressive_dedup.json.gz?dl=0" rel="nofollow">https://www.dropbox.com/s/11mjgy84ms9ldsq/aggressive_dedup.json.gz?dl=0</a></p> <p>The <a href="https://osf.io/s74hg/files/" rel="nofollow">files</a> section of this presentation includes original source code and the resultant data files that were uploaded to <em><a href="http://BigML.com" rel="nofollow">BigML.com</a></em>.</p> <p><a href="https://osf.io/s74hg/wiki/Version%201/" rel="nofollow">Version 1</a> is the original version of this article. As you can see, a very few European or archaic English words (such as "travelling") were accidently included in the list of misspelled words. This is erroneous.</p> <p><a href="https://osf.io/s74hg/wiki/Version%202/" rel="nofollow">Version 2</a> is the next iteration of this study where the few archaic or international variants were excised from the list of 100 marker words and replaced by other, legitimate misspellings. Also in this version of the results, the code first verified that a review was nonempty and in English before computing the incidence ratio of the count of misspelled English marker words divided by the total number of words in the review. Only 0.223% (or 177513) of reviews were either empty or not in English. These were not included in the subsequent graphs, calculations, or DeepNet. An improvement in R-squared by approximately 5% was achieved by these changes.</p>
