15th January 2020 - A Map of Science. v. 1.0<br> I took all Wikipedia pages in outline of natural, formal, social and applied sciences. I manually added "Data Science" as it is not yet in wikipedia classification. Pre processed these pages to get the main content with regular expressions. Stop words removal, lemmatization with WordNetLemmatizer in NLTK, and calculated cosine similarity. I generate a matrix All vs. All and filtered it by calculating zscore and leaving only edges with a zscore > 1.959964 - Used: R, python, igraph, nltk, d3, javascript, html, wikipedia - Alberto Calderone - sinnefa@gmail.com<br>Preview:http://www.sinnefa.com/wikipediasciencemap/<br>
