What is the best way to compute trending topics or tags?

Question

Many sites offer some statistics like \"The hottest topics in the last 24h\". For example, Topix.com shows this in its section \"News Trends\". There, you can see the topics

Answer 1

I had worked on a project, where my aim was finding Trending Topics from Live Twitter Stream and also doing sentimental analysis on the trending topics (finding if Trending Topic positively/negatively talked about). I've used Storm for handling twitter stream.

I've published my report as a blog: http://sayrohan.blogspot.com/2013/06/finding-trending-topics-and-trending.html

I've used Total Count and Z-Score for the ranking.

The approach that I've used is bit generic, and in the discussion section, I've mentioned that how we can extend the system for non-Twitter Application.

Hope the information helps.
