Extracting consumer trends in real time using 100 billion tweets.

Submitted Mar 27, 2013

Connected consumers express everything they feel about products, services, brands in social media. How consumer feel and engage with products is very important for retailers to make better merchandizing decisions.

In this talk we will outline one such system we built to analyze 13 months of twitter data amounting to ~100B tweets.


We will outline a system to extract volume, sentiment, geo trends and related words about any arbitrary topic (defined as a boolean query) from a corpus on 100B tweets increasing at ~500M a day.
