I read on CNN - an article written by Mashable's Peter C - that one of his predictions for 2010 is word cloud becomes more prominent. Though I do see its relevance and standing, I dont see it as often as before on blogs and sites. Perhaps it is being incorporated on a back-end. What do you think? Have you used word cloud on the back end of your online community?

asked whether word clouds are being used on the back end of communities, and wondered if they are worth the fuss. Short answer: yes, but usually as a lightweight analytics or navigation aid rather than a deep analysis tool. Word clouds are great for quick snapshots of frequent terms (titles, tags, recent comments), but they do not convey context, sentiment, or topic structure. Use them as a visual entry point, not the final insight.

A practical backend pipeline that works for communities: collect a rolling corpus (post titles, tags, comment bodies), clean text (strip markup, lowercase, remove stopwords), normalize (lemmatize or stem), detect phrases (bigrams/trigrams), choose a weighting (raw frequency or TF-IDF across documents), then render and cache the cloud. For server-side generation a minimal Python example with the popular WordCloud library looks like this:

from wordcloud import WordCloud

text = " ".join(corpus)  # corpus is a list of cleaned strings
wc = WordCloud(width=800, height=400, background_color="white").generate(text)
wc.to_file("cloud.png")

See the library docs for options and masks: Python WordCloud docs. For interactive client-side clouds consider d3-cloud or wordcloud2.js. Use NLTK or spaCy for phrase detection and lemmatization (example collocations: NLTK collocations how-to). Use TF-IDF when comparing many documents (scikit-learn TF-IDF docs).

Important cautions: merge synonyms and multi-word expressions so counts aren’t split; remove noise and spam; provide an accessible fallback (ordered list and alt text) and cache generated images for performance. Word clouds are a starting visualization—combine them with charts or topic models (LDA) for deeper insight (; W3C image accessibility tips).

I can see word clouds becoming more prominent in many applications but I hope that there are much bigger things in store for 2010!
