Demystifying Data Science: A Live Tutorial
summary
Live demo builds an n‑gram index of RailsConf abstracts, scrapes 497 talks (81 in 2014) with Nokogiri, normalizes text, and stores counts in a redis sorted set so queries return per‑year frequencies (example: programmer overtakes banker in 2014; Ember first appears in 2014). Code runs; frontend (abstractogram.herokuapp.com) visualizes results and the repo (bit.ly/railsconfdata) contains the scraper, ngram generator, and redis ingestion so the pipeline is reproducible.
