LDA-Based Topic Modelling in Javascript: An Update

I’ve just pushed a Javascript version of LDA on my github account. It’s based on my no-longer-functioning earlier work. For testing, I use a subset of the SMS Spam Corpus available here (and thus take no responsibility of the inappropriateness of the text within 🙂 ). Each topic is represented as a word cloud; the larger a word, the more weight it has in the topic. The source sentences are displayed again with a bar which shows the percentage distribution of topics for that sentence. Hovering on each area in the bar would show you the words in the topic. You can of course replace it with any other text, change the number of topics using the slider, and press the ‘Analyse’ button to see it work.
